Regulatory Guide - Holistic Safety (ARPANSA-GDE-1753)

This document provides guidance to licence holders on the interaction of key technological, individual or human, and organisational factors necessary to create and maintain optimal safety.

Introduction

Citation

This publication may be cited as the Regulatory Guide: Holistic Safety (2025). This publication supersedes the Regulatory Guide - Holistic Safety (ARPANSA-GDE-1753).

Background

Charged with the function of protecting the health and safety of people and the environment from the harmful effects of radiation under the Australian Radiation Protection and Nuclear Safety Act 1998 (the Act), ARPANSA adopts a holistic safety approach to the regulation of radiation protection and nuclear safety.

A holistic safety approach considers the role of the whole system in managing safety. This includes technical (equipment, tools, technology, etc.), human (cognition, attention, perception, etc.) and organisational (culture, procedures, work environment, etc.) factors, as well as the interactions between them. 

Holistic safety is an interaction between technical, human, and organisational factors (THOF)

Figure 1: Holistic safety is an interaction between technical, human, and organisational factors (THOF)

Holistic safety also takes a systems-thinking approach which recognises that work exists within a wide system, where safety responsibility and influence spans multiple system levels (Salmon et al., 2023). These levels include the work itself, the staff who perform the work, the leaders (both middle and senior management) who manage the work, the organisation commissioning the work, and external stakeholders (including regulators; Rasmussen, 1997).

ARPANSA encourages the adoption of holistic safety principles. This requires a comprehensive understanding of factors affecting the safety of day-to-day work, especially those that may otherwise be overlooked. This approach aims to prevent the decline of safety performance, in line with International Nuclear Safety Advisory Group (INSAG) Report 15. 

Information and influence should move across all levels of a system hierarchy, and in both directions.

Development of the Guide

This Guide has been developed in consultation with ARPANSA’s international nuclear regulator counterparts, Australian regulators in other high-risk industries, and ARPANSA licence holders. 

These guidelines are consistent with the aims of:

Wherever possible, these references have been provided alongside their relevant factors within this guide.

Purpose

The purpose of this Guide is to provide ARPANSA applicants, licence holders, assessors, and inspectors an updated framework on holistic safety in line with modern best practice. When implemented, these guidelines should support applicants and licence holders in meeting their regulatory requirements, including sections 53(ea), 54(ea), 57A and 60 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations).

A secondary objective is to provide reference to high quality standards and research to assist in the practical application of this Guide. These resources can be used to assess systems and operations, develop internal assessment tools, and integrate holistic safety across organisations.

Scope

This Guide presents a high-level overview of what should be considered when taking a holistic approach. As a guide, the individual recommendations within this document are not regulatory requirements but instead establish ARPANSA’s regulatory expectations for best practice and inform ARPANSA’s approach to making licensing decisions (Act s32(3) and s33(3)).

ARPANSA is the Australian Government’s primary authority on radiation protection and nuclear safety. As such, all factors in this Guide are considered with respect to radiation protection and nuclear safety. Factors in this Guide may overlap with those considered by other regulators (e.g. Comcare). Licence holders should be aware that regulators may take different approaches to these factors due to differences in underlying legislation and jurisdiction.

A graded approach should be adopted by licence holders in the consideration and application of these factors, where the scale of actions taken is proportional to the significance of the associated risk. Licence holders should apply due consideration to the relevance of each factor and ensure alignment with international best practice and other applicable documents.

How to use this Guide

How licence holders should use this Guide

This Guide is designed to be a practical and enabling resource for the application of holistic safety throughout the work lifecycle (e.g. when designing systems, developing procedures, or conducting self-assessments).

The Guide is divided into 4 chapters: Technical Factors, Human Factors, Organisational Factors, and Systemic Factors. Each chapter includes a number of factor categories (e.g., Defence in Depth, Situational Awareness, Work Environment, etc.), which each contain factors. Each factor follows a set structure:

The Guide is divided into 4 chapters: Technical Factors, Human Factors, Organisational Factors, and Systemic Factors. Each chapter includes a number of factor categories (e.g., Defence in Depth, Situational Awareness, Work Environment, etc.), which each contain factors. Each factor follows a set structure:

Licence holders are encouraged to reflect on the relevance and prevalence of each factor in their respective work/workplace. Once relevant factors are identified, licence holders should reflect on the individual considerations and interrogate how effectively those considerations are being addressed by their organisation. Licence holders should also determine where improvements are required and should develop specific action plans to achieve them. Reference tables should be used as additional support in developing actions. 

Where factors have been deemed less/not relevant, licence holders should justify reasons for exclusion. Where reference tables contain a limited number of resources, this should not be interpreted as an indication of the factor's limited relevance. Instead, it underscores the unique value of this document, which extends beyond the scope of factors addressed by other resources. Finally, reference tables are not exhaustive lists of related standards, codes, legislation, or best-practice.

The framework provided in this Guide should become part of a licence holder’s process for designing, implementing and assessing holistic safety in their systems, equipment, tools, tasks and general work environments. This Guide can also be used to inform investigations into incidents and other safety events.

Licence holders should adopt a systematic approach to the application of the factors within this framework and understand how the factors across the 4 chapters interact across the system. When implemented thoughtfully, selected controls and actions can be designed to support multiple factors at once. 

How ARPANSA will use this Guide

This Guide is ARPANSA’s principal document on holistic safety. It will serve as the main point of reference for ARPANSA’s regulatory approach, particularly sections 53(ea), 54(ea), 57A and 60 of the Regulations. This includes in the assessment of licence holder submissions and in conducting inspections.

ARPANSA adopts an evidence-based approach to regulation. Any decisions made by ARPANSA will reflect the data collected from/submitted by licence holders, in line with a graded approach. Where evidence points to issues regarding holistic safety, this may prompt further enquiry.

Chapter 1: Technical factors 

Technical factors are the set of technological and protective conditions that support operators in being safe. This chapter outlines the importance of distinct technical factors and their safety relevance.

Licence holders should demonstrate a concerted effort in addressing these factors when designing and implementing technology and related controls, including the unique interactions introduced by these technologies.

Technical factors are relevant wherever humans interact with technology. While these factors are particularly significant for human-operated technologies, all technology requires some degree of human involvement and organisational support in its design, development, monitoring, maintenance, and decommissioning. Consideration of technical factors, and their interactions with human and organisational factors, throughout each stage will support safety for all degrees of human involvement.

Technology factors

Technology integrations in the workplace can result in unique and unexpected interactions between systems and the people working with them. The factors in this category address the safety implications that may arise from the intersection of technology and the way work is fundamentally performed

Human-machine interfaces

Human-machine interfaces (HMIs) are the point of interaction between a human and a machine. This includes where the machine provides information on its status (output) and where an operator engages with the machine (input). These interfaces can include the user interface of a computer, analogue dials, control panels, etc. Good HMIs support users in making safe decisions by providing accurate and timely information in an intuitive, responsive and easy-to-understand format.

Licence holders should demonstrate:
  • a shared understanding across the workforce of the factors that support and limit the useability of HMIs
  • that HMIs provide accurate and timely information and are intuitive, responsive and easy-to-understand
  • application of proven and best-practice design principles that support the development of good HMIs
  • consistency in the design principles of HMIs used across the organisation
  • availability of training and resources for users on the use of HMIs
  • regular review and revision of HMIs to ensure there are adequately maintained and support the changing needs of users

Note: criteria listed from Performance Objectives and Criteria (facility) in reference tables may differ from matched criteria listed in Performance Objectives and Criteria (sources). Readers will need to compare documents to determine relevant criteria. 

Automation and artificial intelligence

Integration of automation (including semi-automation) and artificial intelligence (AI) into systems involves the transition from ‘humans as controllers’ to ‘humans as system managers’. As the complexity of automation and algorithms grows, so too does the challenge of deciphering the system's internal logic. This has implications for how individuals interact with systems, including how they assess risk, what decisions they make, and what actions they take. Outcomes can be either beneficial (e.g. system efficiency) or adverse (e.g. overconfidence in automated functions or impeded situation awareness) to safety. 

Licence holders should demonstrate:
  • rigorous processes for determining the appropriateness of automation/AI integration before implementation, including understanding the purpose, opportunities, risks and potential safety outcomes
  • thorough piloting processes for verifying the use of selected automation/AI, including acceptance testing
  • routine evaluations of the effectiveness of automation/AI integrations, with action taken to address outcomes
  • clear chains-of-responsibility for automation/AI integrated systems, including operator responsibilities, that are well understood across the workforce
  • processes for managing and responding to events when automation/AI integration fails

Control factors

Applying control measures, in a graded approach, is crucial for protecting safety and security. The following factor(s) address the way in which controls should be designed, selected and layered to provide maximum safety assurances.

Defence in Depth

Defence in depth (DiD) refers to the deployment of successive levels of protection, and is traditionally applied to nuclear safety. However, elements of DiD can be applied to safety generally. Specifically, DiD seeks to:

  • compensate for potential failures (technical, human or organisational)
  • provide, and maintain the effectiveness of, protective barriers
  • protect the public and the environment when protective barriers are ineffective.

DiD, as presented in INSAG-10, is structured in five levels. If one level fails, subsequent levels should take effect. Importantly, conservative design, quality assurance and a mature safety culture are considered prerequisites to the effective implementation of DiD.

Level

ObjectiveEssential means

1

Prevent failures and ensure that anticipated operational occurrences/disturbances are infrequentConservative, high quality, proven design and high quality in construction

2

Maintain the intended operational states and detect failuresProcess control and limiting systems, other surveillance features and procedures

3

Protect against design-basis accidentsSafety systems and accident procedures

4

Limit the progression and mitigate the consequences of beyond-design-basis accidentsAccident management and mitigation

5

Mitigate the radiological consequences of beyond-design-basis accidentsOff-site emergency response

 

Licence holders should demonstrate:
  • implementation of DiD across the facility
  • that adequate action has been taken to implement the relevant levels of defence in depth
  • regular evaluations of the effectiveness of protective barriers used in each successive level
  • evaluation of the independence of defences to prevent cascading effects (e.g. due to tight coupling)
  • the triggering of reviews and updates of controls if a layer of defence fails
  • attention to internal or external events that have the potential to adversely affect more than one barrier at once, or to cause simultaneous failures of safety systems
  • prerequisites of conservatism, quality assurance and safety culture are met
  • that DiD is applied with a graded approach
  • protection of safety barriers/controls themselves

Chapter 2: Human factors

Human factors are the full array of complex mental, physical and psychosocial factors that contribute to an individual’s ability to work safely. This chapter outlines the importance of distinct human factors and their relevance to nuclear safety and radiation protection.

Licence holders should demonstrate consideration and integration of these factors when designing equipment, tools, tasks and the general work environment. This includes understanding how people think and feel, how they interact with each other, and the strengths and limitations of their capabilities (physical, psychological, or otherwise). Applicants and licence holders should further consider how human factors will interact with technical and organisational factors.

Cognitive factors

Cognitive factors relate to how individuals process information, specifically, how they think, perceive, understand and respond to their environment. Understanding human information processing is key as this can impact safety, both directly and indirectly.

The following factors explain the components of human information processing, their role in safety, and the considerations necessary for managing it. 

Cognitive factors

Situation awareness

Situation awareness refers to an individual’s ability to perceive a system’s current status, to anticipate its future status, and to respond appropriately (Endsley, 2015). Put more simply; ‘what is happening, what might happen next, and what can I do about it’. Good situation awareness allows individuals to respond appropriately and rapidly to changing circumstances, thereby supporting safety.

Licence holders should demonstrate:
  • a shared understanding across the workforce of the basic principles of situation awareness, including which factors can affect it, and which can be impacted by it
  • that systems, equipment, tools, tasks and the general work environment are designed to support users in maintaining situation awareness
  • training that develops competence in situation awareness, including how to build it, maintain it and recognise when it has been degraded

Cognitive demands

Cognitive resources like memory and attention are limited and in demand. Individuals rely on these resources to diagnose risks and to guide decision-making. As the complexity of a task increases, so too do cognitive demands. On either extreme, cognitive demands have considerable implications for safety.

Licence holders should demonstrate:
  • a shared understanding across the workforce of the basic principles of situation awareness, including which factors can affect it, and which can be impacted by it
  • that systems, equipment, tools, tasks and the general work environment are designed to support users in maintaining situation awareness
  • training that develops competence in situation awareness, including how to build it, maintain it and recognise when it has been degraded

Cognitive demands

Cognitive resources like memory and attention are limited and in demand. Individuals rely on these resources to diagnose risks and to guide decision-making. As the complexity of a task increases, so too do cognitive demands. On either extreme, cognitive demands have considerable implications for safety.

Balancing cognitive demands is key for optimal performance

Figure 4: Balancing cognitive demands is key for optimal performance

Take for example, an operator who manages a control room with fully automated systems and where human intervention is rarely required. Over time, this operator may become inattentive, complacent or bored. Alternatively, operating a control room where systems are frequently and simultaneously in alarm and human intervention is frequently required may lead them to become overwhelmed, confused, or burnt out. Both cases can have cascading implications for situation awareness, decision-making, and safety overall.

When a task is novel, cognitive demands tend to be high as performance is based on the individual’s knowledge base (as there is no past experience to draw on). Over time, as individuals become more familiar and experienced, performance becomes more rule-based and skills-based, and cognitive demands decrease (Embrey, 2005; Rasmussen J. , 1983). If cognitive demands diminish too much, this can have negative safety implications. 

Optimising cognitive demands to align with the mental capacities of the person conducting the work, and accounting for changes in demands over time, is key to safety performance.

Licence holders should demonstrate:
  • an assessment of the type of cognitive resources in demand when designing systems, tasks, processes, and procedures
  • an assessment of the cognitive demands of work, with consideration for how both high and low demands impact safety
  • alignment of cognitive demands with the capabilities of those performing the work
  • that procedural documents are prepared with consideration of cognitive demands

Sensory perception

Sensory perception refers to the use of senses (vision, hearing, touch, smell and taste) to perceive and understand the physical environment. Accurate perception is necessary for making informed decisions and taking appropriate action. Perceptual deficiencies or overstimulation (e.g. a loud working environment) can interfere with this accuracy, thereby impacting safety.

Licence holders should demonstrate:
  • consideration of human sensory perception, and its limitations, in the design of the physical environment, systems, tasks and procedures
  • assessments of the perceptual requirements of tasks and alignment of these requirements with the capabilities of those performing the work
  • controls to identify and manage factors that may impact perceptual effectiveness

Decision-making

Decision-making is the process of reaching a judgement or choosing an option that meets the needs of a given situation. This can be done casually (intuitively) or analytically (through rational and logical evaluation) or even informed by technology (e.g. artificial intelligence). 

Roadmap illustrating the journey of a good decision-maker

Figure 5: Roadmap illustrating the journey of a good decision-maker

Decision-making, at both an individual and organisational level, should be appropriately conservative, realistic, and proportionate to the potential risks. Taking a conservative approach, where actions are determined to be safe before proceeding, benefits safety. 

Licence holders should demonstrate:
  • a shared understanding across the workforce of how decision-making can contribute to positive and negative safety and security outcomes
  • a conservative approach to decision-making
  • active consideration of multiple options and justification for why one option was chosen over others
  • various decision-making tools, models and processes, and an understanding of their strengths and weaknesses
  • training programs that build competence in good decision-making
  • clearly established roles, responsibilities and powers of individuals for decision-making. These should be well-known across the workforce
  • consistent, transparent and systematic decision-making processes, which prioritise safety and security. This approach should be informed, rational, objective and prudent
  • evaluations of the effectiveness of decision-making and integration of lessons learnt into the decision-making process

Fitness for Duty factors

The factors within this category are those which may impact on both physical and psychological health and wellbeing. Organisations that adopt a holistic approach to the management of these factors protect safety outcomes by ensuring workers are fit for duty. 

Stress and burnout

Stress is the high emotional arousal an individual might feel in response to a physically or cognitively challenging event. Some stress can be beneficial and help motivate individuals to rise to the occasion. This can support safety by promoting vigilance and other positive safety behaviour. However, stress can also become overly taxing on an individual’s physical or mental resources or exceed their ability to cope. This can degrade health and subsequently safety. 

Relationship between arousal and performance

Figure 6: Relationship between arousal and performance

When individuals cope with stress by detaching from work, they are likely to be experiencing burnout. Burnout is a syndrome characterised by emotional exhaustion, increased mental distance from one’s job, and reduced feelings of personal accomplishment (World Health Organization, 2019). 

Stress and burnout impact personal safety as well as one’s ability to uphold one’s safety and security responsibilities at work.

Licence holders should demonstrate:
  • robust mechanisms to identify stressors and manage their implications (realised or potential)
  • design jobs and work methods to consider and mitigate potential stressors
  • adequate allocation of human and technical resources to support with tasks with inherently high demands
  • methods for monitoring and managing employee stress
  • increased opportunities for job control that can be availed by staff when dealing with high demands and other stressors
  • supportive work groups and team resources to share occupational demands across staff
  • training and resources which support individuals to manage stress

Fatigue

Fatigue is a state of tiredness or diminished functioning. Fatigue can be both mental (e.g. complex decision-making), physical (e.g. physical exertion), or both (e.g. extended lack of sleep). Whilst individuals may be able to work through small amounts of fatigue, chronic fatigue can have increasingly dangerous effects on safety. The most insidious aspect of fatigue is that those who are fatigued often cannot recognise their own fatigue and thus, may continue to operate under these conditions. This can have considerable safety implications.

Licence holders should demonstrate:
  • a shared understanding across the workforce on the basics of fatigue, its implications on safety and security, and how to manage it
  • contingency measures and staff planning arrangements to mitigate fatigue-related issues, particularly in the case of shiftwork
  • consideration of external factors which may impact upon staff fatigue, and methods for management of them
  • systems which measure, manage, monitor and report on staff fatigue. This includes peer evaluation and notification of fatigue
  • work and systems that manage fatigue as part of their inherent design

Psychosocial hazards

Psychosocial hazards are workplace factors which can cause psychological harm. These may arise from the design or management of work itself, the work environment, or workplace interactions. Psychosocial hazards can also interact to create new, changed, or more complex risks. For example, high workloads may become more hazardous when individuals also have insufficient breaks or poor peer support. Without intervention or controls, psychosocial hazards can impact safety (for example, by degrading decision-making or problem-solving abilities).

Licence holders should demonstrate:
  • a systematic approach to identifying reasonably foreseeable psychosocial hazards and eliminating or minimising them
  • psychosocial hazards and risk management forms part of the design of training, systems, tasks, policies and processes and other key elements of work
  • awareness and implementation of different psychosocial intervention methods, and their effectiveness
  • routine evaluations of the effectiveness of implemented controls for psychosocial hazards, and adjustments made to ensure risks are reduced

Alcohol and other drugs

The effects of alcohol and other drugs (AOD) can impair one’s fitness for duty by degrading the physical and mental functions that are critical to safety. These include:

The effects of AOD

Identifying and managing staffs’ use of AOD is critical for reducing the risk of injury, harm and other negative safety outcomes. 

Licence holders should demonstrate:
  • clear documentation and circulation of policies that deal constructively with AOD use and outline the standards and expectations of staff
  • assessments of factors that may contribute to AOD use (including the physical environment, availability, stress, job characteristics and management style)
  • mechanisms that address, limit, or eliminate factors that may contribute to AOD use
  • established procedures for the detection, assessment and reporting of AOD use, including the use of legal substances that can impair function or magnify the effects of AOD

Physical ergonomics 

The physical capabilities of an individual impact how they engage with equipment, tools, technology, tasks and the general work environment. The following sections outline the interplay between physical capabilities and safety and specifies the considerations necessary to ensure work environments are designed with consideration for those working within them.

Physical work environment

Physical work environment refers to the design of an individual’s and team’s workspace (e.g. desk, workbench) and the surrounding environmental conditions (e.g. lighting, noise, cleanliness). This can include the interactions between multiple workflows. Designing spaces to avoid unnecessary stresses and strains (e.g. postural risks and repetitive strain), whilst maintaining useability and accessibility, can help decrease the chance of error and enable safe practice. 

Reducing the change of drops
Licence holders should demonstrate:
  • that the design of the physical work environment eliminates or minimises hazards or risks to safety
  • design and implementation of training, systems, tasks, policies and processes support a safe physical work environment
  • routine assessment of the physical work environment and its impact on individuals, their work and overall outcomes
  • a process to review and revise the physical work environment to ensure it remains optimised for the needs of people and the organisation

Anthropometry

Anthropometry is the measurement of the proportions, size and form of the human body, and the application of this information to the design of workspaces and equipment. Anthropometric design helps ensure that an individual’s full functional capacity is maintained when doing a task. For example, hazmat suits should adequately conform to an individual’s physical dimensions, or equipment at workstations should be easily accessible for individuals of different heights and limb lengths. Importantly, this requires a thorough understanding obtained via assessment of the actual user group. 

Licence holders should demonstrate:
  • an assessment and understanding of the user group to guide anthropometric design activities
  • use of anthropometric measurement and analysis in the design of equipment, tools, technology, tasks and the physical work environment (e.g. layout)
  • use of anthropometric techniques to evaluate the appropriateness of equipment, tools, technology, tasks and the physical work environment, and action taken to address the outcomes of these evaluations

Chapter 3: Organisational factors 

Organisations are complex structures, with individuals, teams and leadership working together with equipment, systems, and technology, inside a dynamic working environment, to uphold safety. This chapter outlines the importance of distinct organisational factors and their relevance to nuclear and radiation safety.

Licence holders should demonstrate a concerted effort to address these factors when developing the policies, processes, procedures and practices for their broader organisational systems. This includes thinking and responsive planning for the long-term. Addressing organisational factors should involve the consideration of their impacts and interactions with technical and human factors.

Workforce factors

The factors in the following section address an organisation’s ability to develop and ensure their workforce possesses the fitness, readiness, capacity, and capability to perform their work safely, as both individuals and as a team.

Competence and training

Competence is the collection of knowledge, skills and experience necessary for an individual to perform their duties to a recognised standard, including those set for safety and security. Having a competent workforce is crucial for safe operations.

Training (and assessment) is a key mechanism for ensuring that competence is achieved and maintained. Training involves updating, developing, applying and practising knowledge and skills. Together, competency and training help mitigate safety issues that may arise from a lack of knowledge and/or skills.

Licence holders should demonstrate:
  • a competent workforce that ensures safety and security standards are upheld
  • rigorous processes for determining the requisite competencies of safety related roles across all levels of the organisation, including leaders
  • regular assessments of the competence of individuals to work safely across all levels of the organisation, including leaders
  • that training builds competence to the required standard before any work is carried out
  • that training is clearly linked to role requirements, includes learning objectives, and defines satisfactory performance, including for leaders
  • that training is proactive, rather than reactive, and conducted regularly to maintain competence
  • that training effectiveness is measured and used to improve systems of training
  • succession planning arrangements that compensate for the departure of competent staff

Recruitment and resourcing

Recruitment and resourcing refer to the selection and acquisition of staff, including contractors and consultants. This requires an appropriate number of suitably qualified and experienced persons (SQEPs) who are equipped with the resources (budget, time, training, etc.) necessary to perform their duties safely. This includes taking a long-term view of the organisation, anticipating future needs, and planning accordingly.

Licence holders should demonstrate:
  • sufficiency in resourcing (including personnel) needed for running a safe operation
  • long-term planning of resources important for safety, including succession plans for safety functions or positions of expertise/leadership
  • regular evaluation of current and future resource constraints, their potential impacts upon safety, and strategies to mitigate adverse effects.
  • organisational structures which appropriately place SQEPs, in a manner that positively impacts safety and addresses resourcing constraints
  • established and documented standards for the minimum level of education, experience, knowledge and skills required for all roles in the organisation
  • rigorous and robust methods for the assessment and selection of SQEPs, and validation of these methods

Communication

Communication is the interdependent exchange of information between parties, through speaking, writing, reading, listening, and remotely.

Communication is the interdependent exchange of information between parties, through speaking, writing, reading, listening, and remotely

Figure 8: Good communication ensures a focus on safety, resulting in these outcomes

Effective communication can be a management aid for achieving shared meaning and driving safe performance. Ineffective communication can degrade safety by increasing the frequency and severity of errors. The effectiveness of communication depends on characteristics of the sender (e.g. clarity of message), characteristics of the receiver (e.g. receptiveness), and noise (e.g. distractions).

Effective communication is key to achieving shared meaning

Figure 9: Effective communication is key to achieving shared meaning

Licence holders should demonstrate:
  • a shared understanding of the benefits of effective communication and the risks of inadequate communication on safety and security
  • a shared understanding across the workforce of the barriers to effective communication, including types of communication errors and how to avoid them
  • free flowing information across the organisation and with regulators, that builds transparency for internal and external stakeholders
  • communication channels which facilitate flow of information upwards (from staff up to leaders), downwards (from leaders down to staff), and sideways (between those at the same level)
  • mechanisms for verifying that the message communicated has been interpreted as intended
  • dedicated communication channels for contractors, with regular communication to and from contractors
  • availability of different communication methods, tools and modes of delivery, and an understanding of the strengths and limitations of each
  • established systems, processes and policies that support effective internal and external communication
  • training on the non-technical skill of communication

Team Dynamics

Teams are groups of individuals, guided by a leader, working interdependently towards a common goal. The personal qualities, behaviours, styles and strategies adopted by both the individuals and the leader of a team influence safety. Leaders set the tone for safety by influencing norms, deciding on action, and allocating resources. This includes the leadership demonstrated by those outside of technical areas, as their example and decisions still impact upon safety. For example, a budgetary decision made by the CFO may apply a financial constraint that impacts the safety of work.

Groups that demonstrate good team dynamics can better adapt to adversity and solve more complex problems, thus supporting safety. 

Licence holders should demonstrate:
  • systems, policies, processes and procedures that support effective leadership and teamwork
  • a shared understanding across the workforce of individual and group characteristics that influence team dynamics, including leadership
  • a shared understanding across the workforce of the risks of inadequate leadership and teamwork and the benefits of effective leadership and teamwork on safety and security
  • that staff are aware of their individual role/responsibility within teams, especially leaders
  • that teams work effectively without diminishing the questioning attitude of individuals
  • training on the non-technical skill of leadership and teamwork

Safety culture

Safety culture is the assembly of values, attitudes, and behaviour of individuals that result in and from a collective commitment to safety. This commitment establishes safety as the overriding priority within an organisation [26, 47].

Leadership for safety

Leadership significantly influences the safety culture of an organisation. The more senior a leader, the greater their influence on culture. This influence is exerted through the policies they enact, the example they set, and the expectations they place on their staff. ‘Leadership for safety’ acknowledges the considerable role of leaders in shaping culture and outlines the approach that should be adopted to demonstrate that safety is the top priority.

A visual representation illustrating the greater influence of more senior leaders in an organisation

Figure 11: A visual representation illustrating the greater influence of more senior leaders in an organisation

Leadership for safety comprises:

  1. commitment to safety as a value
  2. responsibility and accountability
  3. communication, engagement and oversight.

Commitment to safety as a value

Leaders should hold, demonstrate, and institutionalise a strong commitment to safety as a core organisational value. 

Licence holders should demonstrate:
  • setting a good example for safety by role modelling safe behaviour and reinforcing safety as the overriding priority
  • commitment to ensuring safety including both proactive and reactive involvement from all levels of leadership
  • commitment to safety is reflected in all decisions, statements and actions, and not just on paper                                                                        

Responsibility and accountability

It is important for leaders to understand, establish and adhere to their safety responsibilities and accountabilities.

Licence holders should demonstrate:
  • that authority, roles and responsibilities for safety are specific, well-defined and well-understood
  • that ultimate responsibility and accountability for safety lies collectively with the CEO, or equivalent, of the licence holder and the senior management team of the licence holder
  • the conditions necessary for safe operation, including that resources have been appropriately planned and dedicated, and that rewards and sanctions are appropriately distributed
  • strategic, long-term alignment between organisational policies and safety goals, ensuring they are measurable and periodically reviewed
  • single points of accountability within senior leadership for each activity, group and work area

Communication, engagement and oversight

Leaders shall engage and communicate across their organisation and ensure adequate safety oversight. 

Licence holders should demonstrate:
  • open, candid and free flowing communication, where information is shared both vertically and horizontally
  • regular communication of decisions and actions that impact on safety, and the rationale behind them. Communication on change is particularly important
  • active involvement and engagement with individuals across the organisation to improve safety.
  • receptiveness to feedback and constructive criticism from across the organisation
  • visible engagement with the workforce (e.g. field presence), which includes asking questions, reinforcing expectations and maintaining one’s own situation awareness
  • an environment where lessons learnt are systematically shared and integrated across the organisation, preventing the formation of silos
  • that trust is cultivated across the organisation, and everyone is treated with dignity, respect and openness
  • informed questioning and strong oversight on safety matters
  • recognition, encouragement and rewarding of behaviour that promotes safety, and coaching or sanctioning of behaviour that may hinder safety
  • that an independent safety group is established, with real powers to investigate and intervene, reporting directly to the CEO

Individual responsibility

All individuals have a responsibility for safety, for both themselves and others. Individuals should feel a sense of ownership in knowing their safety responsibilities and striving to fulfil them.

Licence holders should demonstrate:
  • safety responsibilities and expectations for each role are specific, well-defined and well-understood by all individuals
  • individuals have a strong sense of personal ownership for safety, and share learnings with others when necessary
  • individuals adhere to set policies, procedures, processes and practices, particularly those relating to safety
  • a culture that empowers staff to not report for duty if they believe themselves to be unfit
  • individuals are responsible for collaboration and transparent communication across the organisation. This includes valuing diverse perspectives to safety and sharing safety lessons
  • individuals understand their expectations for the reporting of safety events and the subsequent updating of procedures and practices

Values and behaviour

A safe organisation will, at all levels, possess shared values and beliefs for safety. These values and beliefs produce and inform behavioural norms, which provide appropriate attention to safety and its prioritisation over competing goals.

Licence holders should demonstrate:
  • safety is the top priority for all individuals
  • safety and production are seen to go hand in hand
  • respect, trust and honesty are valued and cultivated
  • an understanding (especially by leadership) of the impact of incentives/KPIs on the prioritisation of safety
  • formal and informal reinforcement of safety values and behaviour

HSCMLR.1, LR.6, WE. 

Questioning attitude

A ‘questioning attitude’ is one where individuals are able and encouraged to question their work and working environment. This requires individuals to avoid complacency, remain vigilant, and voice concern even when the concern seems minor. This supports safety by identifying potential risks and taking action.

Licence holders should demonstrate:
  • that a questioning attitude is adopted, encouraged and enabled across the organisation
  • that individuals are encouraged and enabled to offer different perspectives regarding safety, e.g. formal and informal systems for feedback and concerns
  • that individuals understand the unique risks associated with their work, including potential safety implications
  • that individuals are enabled to stop work when uncertain of the risks, and to seek advice before proceeding
  • that individuals remain vigilant and avoid complacency

GSR Part 23.2c, 5.2e
HSCMQA., RC. 

Just culture and fairness

A ‘just culture’ is one that acknowledges that errors are inevitable. Errors reflect a wider system of failures rather than a failure of the individual. A just culture balances safety and accountability (Dekker, 2007) by fairly distributing rewards and sanctions. Individuals are encouraged to continue reporting issues, even when linked to their own actions. This satisfies the need for accountability and provides an opportunity for learning and improvement. 

Fairness requires a consistent approach to be taken in the rewarding, sanctioning and general treatment of all staff. This is key to building a just culture.

Licence holders should demonstrate:
  • a shared understanding across the workforce of just culture and fairness, and how it impacts safety.
  • an approach of ‘just culture’ across the organisation.
  • policies upholding individuals’ rights for fair and confidential treatment, including intolerance of harassment, intimidation, retaliation or discrimination for raising safety concerns.
  • fairness in rewarding and sanctioning actions that is consistent across all individuals.
  • fairness in resolving conflicts, in a timely manner

HSCMLR.6, WE., RC.

Management systems

A comprehensive definition of management systems can be found in ARPANSA’s Regulatory Guide - Plans and arrangements for managing safety (ARPANSA-GDE-1735). Management systems are relevant to holistic safety due to their ability to influence an organisation’s safety culture, and for this safety culture to influence management systems in return. Management systems are the key location of the information required to conduct work safely. 

Procedure management

Procedure management refers to the foundational role of documented procedures in supporting safety. When properly implemented, these procedures offer a consistent, risk-assessed approach to work. Procedures that accurately reflect work-as-done, and are adhered to, contribute meaningfully to achieving safety objectives. Importantly, effective procedure management requires the support of underlying policies and processes, as well as good document management practices. Good oversight over, and periodic updates of, documents including creation, maintenance, management, and use of documents can safeguard against risks to safety.

Licence holders should demonstrate:
  • processes and procedures, particularly those impacting safety, are well-documented, precise, logical and readily available
  • routine reviews and updates of documented processes and procedures, ensuring that they reflect work ‘as done’ and optimise safety
  • a consultative approach to the design, development, documentation, and evaluation of processes and procedures
  • clear ownership of procedures, policies and underlying documentation
  • retention of records over time to support knowledge management and operational longevity
  • that risk assessments are conducted and reviewed for all procedures
  • that adherence expectations are established and systems for monitoring adherence are implemented
  • that the design of processes and procedures considers the human operator undertaking each stage of that process/procedure, including human reliability
  • quality assurance measures which verify that procedures are consistent, readable, current, and version controlled
  • consideration of the interaction of a given process or procedure with another
  • consideration of the information that needs to be communicated between different groups related to processes and procedures
  • that where there is deviation from procedures, the deviations are reported, risks are assessed and procedures updated

Change management 

Change management is the process of undertaking change in a systematic and methodical way. Good change management maintains safety throughout all phases of the change. A typical change management process involves the following steps: 

The change management process

Figure 10: The change management process

These steps should be followed diligently to ensure that changes have no detrimental effects on safety. 

Where a change has significant implications for safety, licence holders require prior approval from the CEO of ARPANSA under section 63 of the Regulations. Thresholds for when and how to seek approval can be found within ARPANSA’s Regulatory Guide - When to seek approval to make a change with significant implications for safety (ARPANSA-GDE-1751).

Licence holders should demonstrate:
  • that changes are adequately justified
  • that the method chosen for conducting a change is selected as the best from a range of possible options
  • a systematic, transparent and rigorous change management process, applied to all types of change, including assessment of the cumulative impact of multiple changes. The rigour of this process should be proportionate to the significance of the change
  • a clear and well-communicated change management policy that prioritises safety
  • adequate resourcing to support and manage change. This includes resourcing for retraining where necessary
  • regular reviews of change as it progresses, and action taken to address any issues identified
  • the presence and use of mechanisms for communicating and capturing the outcomes of changes. This includes communicating these outcomes with the regulator

Project management

Project management is the application of knowledge, skills, tools and techniques, to plan activities that meet the needs of a project. A project typically spans 5 phases: 

Project timeline

Figure 11: The typical timeline of a project

Managing safety is an integral part of project management and interacts with all phases of the project lifecycle. Making safety considerations early in the project planning phase may offer the greatest protection to safety outcomes. 

Licence holders should demonstrate:
  • projects are planned, communicated and implemented in a manner that promotes safety
  • projects manage risks (both planned and unexpected), including identification, analysis, response planning, monitoring and control
  • project documents are clear on the roles and responsibilities of project team members, including their safety responsibilities and accountabilities
  • projects managed externally remain aligned with the organisation’s safety standards, and ultimate accountability for safety remains with CEO, or equivalent, of the licence holder and the senior management team of the licence holder

Contractor management

Calling upon the expertise of external service providers is often necessary. However, the use of contractors (incl. consultants) can introduce safety risks when improperly managed. Having a robust contractor management system can help mitigate these risks. This system should put in place arrangements that specify, monitor, and manage contractors in a way that aligns with the safety standards of the organisation.

Licence holders should demonstrate:
  • characteristics of an ‘intelligent customer’ in the use of contractors, ensuring the organisation is not adversely impacted in its ability to manage safety
  • a contractor management system that specifies, monitors and manages contractors according to set safety standards
  • policies, processes, procedures and practices (especially those regarding safety) extend to contractors
  • clear documentation and communication of the safety responsibilities of contractors, whilst acknowledging that ultimate responsibility for safety is retained by the licence holder

Chapter 4: Systemic factors

This category addresses broader factors which should be integrated into all systems across an organisation. The absence of these factors may signal an incomplete or potentially unsafe organisational system.

Resilience

Resilience refers to a set of abilities that enable a system to maintain or regain a safe and stable state. Systems achieve this by adjusting themselves before, during or after an event, and continuing to operate safely in both expected and unexpected conditions.

A resilient system is one which has the ability to respond, monitor, learn and anticipate (Hollnagel, 2010)

 strong resilience

Figure 12: The abilities which enable strong resilience

The ability to respond

The ability to respond involves taking appropriate action to maintain or regain a safe and stable system state. This requires individuals to know what to do to adjust to both expected and unexpected conditions, including when to enact planned actions.

Licence holders should demonstrate:
  • regular appraisals of their systems to identify potential deviations that may lead to changes to the safety and stability of a system, including human factors
  • that individuals are equipped with the capability to respond to any deviations (both expected and unexpected) and to return the system to safe and stable operations
  • response capabilities and readiness are maintained for both emergency and non-emergency scenarios

The ability to monitor

The ability to monitor involves identifying and keeping track of indicators that help determine the safety and stability of a system. This includes indicators which both positively and negatively impact upon safety. Importantly, a long-term approach to monitoring is crucial, particularly in recognising slow, incremental changes that could have significant safety implications over time (i.e. drift; Dekker, 2011).

Licence holders should demonstrate:
  • a regularly updated and validated list of indicators relevant to monitoring the status of systems, including human factors
  • routine monitoring of indicators, ensuring they are tracked, trended, evaluated and acted upon in a timely manner
  • methods for identifying and managing factors that may impact the fitness for duty of the workforce
  • active monitoring of long-term trends, including the incremental cutting back of safety margins and resources
  • active monitoring and evaluation of remedial actions, including mechanisms for feeding back this information into a cycle for continuous improvement
  • that quantitative assessments and analyses, including of human reliability, use values derived using verified, transparent methods that avoid subjective judgements
  • that qualitative assessments, analysis and arguments establish clear criteria and apply consistent methods so as to avoid subjective judgements
  • comparative assessments which benchmark the organisation against equivalent (national or international) organisations

The ability to learn

The ability to learn involves taking stock of past events, generating insights and lessons learnt, and understanding and leveraging these lessons to improve systems. The effectiveness of learning is impacted by which events are captured, how well they are analysed, and how meaningful the derived lessons are.

Licence holders should demonstrate:
  • clear and systematic principles to determine which events to investigate (including near-misses)
  • sufficiency in resourcing to facilitate data collection, analysis and learning
  • integration of lessons learnt (of both what did and did not go well) to drive improvements in safety
  • learning that is effective, timely, continuous and shared across the organisation
  • learning facilitated by both internal self-assessments and, where appropriate, external assessments

The ability to anticipate

The ability to anticipate involves forecasting for potential events, conditions, threats or opportunities that may either benefit or hinder the safety and stability of systems. Furthermore, it involves making plans and preparations to address them.

Licence holders should demonstrate:
  • systems and arrangements (including resources) dedicated to the role of anticipating future safety challenges
  • regular reviews of potential future events that may impact upon safety, including human factors
  • appropriate communication of anticipated future events and their safety impact to the wider organisation
  • developed plans and arrangements that address anticipated future events

Hierarchy of Controls

The Hierarchy of Controls (HoC) is a sequential approach to managing risk, arranged from most to least effective. Employing the highest level of control (elimination) is desirable and encouraged. However, this may not always be practicable. In this case, subsequent levels of control should be implemented. Effective protection will often involve the deployment of multiple controls across the hierarchy, with resources prioritised for controls higher in the hierarchy (e.g. engineering controls such as interlocks must be supported by maintenance and inspections procedures to effectively manage safety). 

Selecting which controls to deploy will require a thorough understanding of the people performing the work, the technologies they use, and the environment within which they operate. Importantly, controls must be visible and well understood by workers to be effective. Otherwise, they are routinely violated and often fail.

The hierarchy of controls demonstrates the various ways in which risk can be mitigated

Figure 13: The hierarchy of controls demonstrates the various ways in which risk can be mitigated

Licence holders should demonstrate:
  • robust assessments that identify hazards across the organisation
  • processes for determining controls including the consideration of multiple options
  • justification for the controls selected, including combinations of controls across the hierarchy
  • appreciation for human aspects when selecting, designing, implementing and maintaining controls
  • implementation of controls and that they are being used effectively across the organisation
  • that workers are aware of, and understand, the controls that are in place and what they protect against
  • routine evaluations of the effectiveness of controls, and action taken to address outcomes

User-centred design

User-centred design (UCD) places the end user at the centre of the design process. This helps designers understand (and design to) the needs of the end user, the work they do, and their work environment. Safety can degrade when design does not appropriately account for the real-life use cases of end users. For example, having touchscreen equipment in a lab where workers are wearing protective gloves, rendering the touchscreen unusable. UCD addresses this by encouraging users to participate in the design process upfront, thus helping protect systems from the threats of traditional design methods. 

Licence holders should demonstrate:
  • a shared understanding across the workforce of the principles of good and poor UCD, and their implications for safety
  • application of UCD principles in the design of systems, equipment, tools, tasks and the physical work environment
  • application of inclusive design practices within a UCD approach
  • regular reviews of systems to ensure they remain user-centred and meet the current needs of end users

Security

Security is an essential part of safety, where any controlled source, apparatus or facility can only be considered safe if it is also secure.

Security Integration

Security concerns the implementation of systems and a culture which supports:

Security Integration

The common aim for these different forms of security is to mitigate the potential harm caused intentionally by bad actors, or inadvertently by good actors, to themselves or others.

Nuclear Security Culture

Nuclear security culture refers to the assembly of characteristics, attitudes and behaviours of individuals, organisations and institutions, which serve to support and enhance nuclear security. Whilst safety culture and security culture share common goals, security culture places additional emphasis on deliberate acts that are intended to cause harm. For this reason, a different set of attitudes and behaviour are required to establish a good security culture.

Safety-Security Intersection

At times, safety and security may be competing priorities. To ensure safety remains the overriding priority, without jeopardising security, it is important to understand and manage where safety and security intersect. 

Licence holders should demonstrate:
  • consideration and integration of security in policies, processes, procedures and practices, without negatively impacting safety
  • effective security measures to meet the requirements of personnel security, including in recruitment
  • effective security measures to meet the requirements of information security
  • effective security measures to meet the requirements of physical security
  • a strong security culture that is supported by all individuals and leadership, with appreciation for the different focuses of safety and security culture
  • identification and management of the intersecting priorities of safety and security

Glossary

Note: Definitions for each factor included in this Guide are provided at the beginning of their respective sections.

 

Accountability

Being answerable for safety outcomes due to holding ownership over a system and its risks.

Contractor

A worker who is external to the licence holder’s organisation, but who performs work on behalf of the licence holder.

Constraint

Any system element that imposes limits on other parts of the system. These limits could be on resourcing, finances, time, radiation dose, etc.

Continuous improvement

The ongoing process of identifying, analysing, and making incremental improvements to systems, processes, procedures, and practices. 

Control

An element of, or change in, design which intends to eliminate or mitigate the risk of adverse events.

Coupling 

The degree of interdependence that exists between system elements. Tight coupling between system elements may allow for cascading failures through the system. Loose coupling may reduce control over the system.

Graded approach

An approach where the scale of actions taken is proportional to the significance of the risk

Holistic safety/holistic approach

A best-practice approach which considers technical, human and organisational factors, including how factors interact and the relationships between them.

Incidents, near misses and deviations 

Incident - the Regulations state that an “incident means:

(a) any unintended event, including an operating error, equipment failure, initiating event, accident precursor, near miss or other mishap; or

(b) any unauthorised act, whether or not malicious;

the consequences or potential consequences of which are not negligible.”

Near miss - an incident in which no harm was done to individuals or the environment, but where these consequences were narrowly avoided due to controls failing, or not being present.

Deviation - Any circumstance which results in a departure from normal conditions. A deviation may or may not result in an incident. For example, an authorised departure from procedure which results in no adverse consequences is still considered a deviation.

Heuristics

Mental short-cuts or rules of thumb which are less cognitively demanding but may oversimply a situation or event.

Intelligent Customer

The capability of the organization to have a clear understanding and knowledge of the product or service being supplied. The ‘intelligent customer’ concept relates mainly to a capability required of organizations when using contractors or external expert support.

Management system

The systems, tools and processes that allow for effective record-keeping, information availability and quality assurance, particularly during periods of development and change.

Performance

The extent to which a person is capable of carrying out a task or process safely and successfully.

Safety

Safety is the ability to perform work in varying, unpredictable environments without causing harm. This is demonstrated by the presence of defences, not the absence of accidents. 

System

A set of dynamically interacting elements. These elements include technologies, organisational structures and people.

This guide refers to multiple systems.

Systems-thinking

An approach which considers systems as a whole and emphasises the interactions and relationships between elements of the system. This often involves the consideration of a hierarchy which groups system elements in to work design, frontline staff, management, the organisation, and external elements (including government, regulators and the public).

Work-as-done

The way in which work is actually performed, rather than the way it is expected to be done when planning (work-as-planned).

Regulatory Guide – How to determine whether a UV source is a controlled apparatus (ARPANSA-GDE-1747)

 

1. Purpose

This document is provided to assist controlled persons to determine whether an ultraviolet (UV) source is classed as controlled apparatus under the Australian Radiation Protection and Nuclear Safety Act 1998 (the Act). In particular, it clarifies the conditions specified in section 9 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations). A number of case studies where typical UV emitting apparatus have been assessed in accordance with this guide have been published in the document UV emitting apparatus – case studies.

This document is valid for both pulsed and continuous sources of UV radiation where the exposure duration is not less than 0.1 ms. It does not apply to UV lasers. Exposure to lasers are covered by laser standard AS/NZS IEC 60825.1 Safety of laser products.

Reference documents

Radiation Protection Standard for Occupational Exposure to Ultraviolet Radiation (2006), ARPANSA Radiation Protection Series No. 12 (RPS 12). Extracts from this document can be found in Appendix 1.

To fulfil the requirements of section 2.1 of RPS 12 supplementary information and management plans for controlling exposure to UVR can be found on the ARPANSA website:

Read this document in conjunction with Regulatory Guide: UV emitting apparatus case studies.

2. Definitions

Exposure limit: the exposure which it is believed that nearly all workers can be repeatedly exposed to without adverse effect (exposure limits for UV are given in Schedule 1 of RPS 12).

Note: The exposure limits apply to artificial sources of UVR. Due to highly variable ambient solar UVR levels the application of exposure limits is not practical and limiting solar UVR exposure to as low as possible is the most effective approach.

Permissible exposure time, tPET: the time it takes to reach the exposure limit (calculated according to Schedule 1 of RPS 12).

3. Controlled apparatus

In section 4 Group 1 table of the Regulations defines an optical source, other than a laser product, emitting ultraviolet radiation, infrared or visible light as controlled apparatus.

4. Criteria to be satisfied

Section 9 of the Regulations consists of two separate criteria, both of which must be fulfilled for the apparatus to be classed as controlled apparatus.

The first criterion, paragraph 9(1)(b) concerns source emission. It is fulfilled if the apparatus produces non-ionising radiation that could lead to a person being exposed to radiation levels exceeding the non-ionizing radiation exposure limits. For UVR the relevant standard referred to in section 4 is Radiation Protection Standard for Occupational Exposure to Ultraviolet Radiation (2006), ARPANSA Radiation Protection Series No. 12 (RPS 12).

The second criterion, paragraph 9(1)(c) is based on the accessibility of the source. Factors determining whether radiation above the exposure limits is accessible to persons have to be evaluated. The condition is fulfilled if excess levels of radiation are readily accessible to persons in any of the following situations:

  • in the course of intended operations or procedures of the apparatus; or
  • as a result of a reasonably foreseeable abnormal event involving the apparatus; or
  • as a result of a reasonably foreseeable single element failure of the apparatus; or
  • without the use of tools or other specialised equipment required to remove protective barriers or access panels.

If the apparatus is not one of the exempt dealings in section 44(7) of the Regulations the procedure in the next section describes how to go through these two criteria to determine whether a UVR source is classed as controlled apparatus or not.

5. Procedure

This procedure (as show by the flow chart on page 4) will assist you to determine whether your apparatus is controlled or not. 

  1. If the apparatus is a transilluminator or germicidal lamp where the emission is accessible, it is classed as controlled apparatus.
  2. If the apparatus is a fluorescence microscope, a spectrophotometer or a high-performance liquid chromatography (HPLC) where the light source is completely enclosed, it is not controlled apparatus.
  3. If there is a reasonably foreseeable abnormal event involving the apparatus that would lead to a person being exposed to levels above the exposure limits, the apparatus is classed as controlled apparatus. Examples of this are: forgetting or using the wrong PPE, possible exposure during normal maintenance, not using prescribed shielding to cover a sample, easy overriding of an interlock etc.
  4. If there is a reasonably foreseeable single element failure of the apparatus that would lead to a person being exposed to levels above the exposure limits, the apparatus is classed as controlled apparatus. An example of this is a malfunctioning interlock. A failsafe interlock would not lead to a person being exposed as no UVR is emitted if the interlock fails.
  5. If a person can receive excess levels of radiation when removing protective barriers or access panels that do not require the use of tools or other specialised equipment, then the apparatus is classed as controlled apparatus.
  6. Determine if the source emits UV radiation that could lead to a person being exposed to radiation levels in excess of the exposure limits in the course of intended operations or procedures. Calculate the permissible exposure time, tPET, according to the method described in Schedule 1 of RPS 12.

Notes:

The distance to the source when the unit is in operation should be taken into account. Using the inverse square law the radiation level is calculated at the position where the closest person is situated. If the unit is handheld and no distances are specified: assume that the skin and eyes are 20 cm and 50 cm, respectively, from the source.

Embedded devices can be designed in such a way that it can be considered safe for their intended use and during normal operation as the emission hazard only becomes accessible during service or maintenance. i.e. protective housing, interlocks and other organisational safety measures. The servicing of embedded UV sources can increase the risk of injury as the servicing may include various adjustments. To carry out servicing in a safe manner it may be necessary to implement temporary procedures and safeguards appropriate to the increased level of risk. Manufacturers may provide advice on safe procedures during servicing and maintenance.

Compare with the maximum exposure duration, texp.

If  texp> t PET  the apparatus is classed as controlled apparatus.

If      the apparatus is not classed as controlled apparatus.

Appendix 1

Extracts from Schedule 1 Radiation Protection Standard for Occupational Exposure to Ultraviolet Radiation (2006)

Radiation Protection Series No. 12

Exposure Limits (EL) for UVR from Artificial Sources 1

S1.1 The EL for occupational exposure to UVR incident upon the skin or eye where irradiance values are known and the exposure duration is controlled are as below. Note that S1.2 and S1.3 must both be satisfied independently.
S1.2   For the UV-A spectral region 315 to 400 nm, the total radiant exposure on the unprotected eye must not exceed 10 kJ.m–2 within an 8 hour period and the total 8 hour radiant exposure incident on the unprotected skin must not exceed the values given in Table 1. Values for the relative spectral effectiveness are given up to 400 nm to expand the action spectrum into the UV-A for determining the EL for skin exposure.
S1.3 In addition, the ultraviolet radiant exposure in the actinic UV spectral region (UV-B and UV-C from 180 to 315 nm) incident upon the unprotected skin and unprotected eye(s) within an 8 hour period must not exceed the values given in Table 1.
S1.4 

For broadband sources emitting a range of wavelengths in the ultraviolet region (ie most UVR sources), determination of the effective irradiance of such a broadband source is done by weighting all wavelengths present in the emission with their corresponding spectral effectiveness by using the following weighting formula:

Eeff       =       ∑Eλ. Sλ. ∆λ

where

Eeff       =       Effective irradiance in W.m–2 (J.s–1.m–2) normalised to a monochromatic source at 270 nm

Eλ              =       Spectral irradiance in W.m–2.nm

Sλ              =       Relative spectral effectiveness (unitless)

λ             =       Bandwidth in nanometres of the calculated or measurement intervals

S1.5  Permissible exposure time in seconds for exposure to actinic UVR incident upon the unprotected skin or eye may be computed by dividing 30 J.m–2 by Eeff in W.m–2. The maximum exposure duration may also be determined using Table 2 of this Schedule which provides representative exposure durations corresponding to effective irradiances in W.m–2 (and μW.cm-2).

1 These exposure limits are intended to be used as guidelines only for Solar UVR exposure.

Regulatory Guide - How to determine whether a Class 1M or Class 2M laser product is a controlled apparatus (ARPANSA-GDE-1739)

On this page

1. Purpose

This document is provided to assist controlled persons to determine whether a Class 1M and Class 2M source is classed as a controlled apparatus under the Australian Radiation Protection and Nuclear Safety Act 1998 (the Act). In particular, it clarifies the conditions used in section 9 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations).  

Reference documents

AS/NZS IEC 60825.1 Safety of laser products Part 1: Equipment classification and requirements
AS/NZS IEC 60825.2 Safety of laser products Part 2: Safety of optical fibre communication systems (OFCS) 
AS/NZS IEC 60825.14 Safety of laser products Part 14: A user’s guide

2. Background

There are currently eight classifications for lasers based on the likelihood of injury. The classification of a laser is used to develop safety control measures. The Accessible Emission Limit (AEL) is the maximum accessible emission permitted within a particular class of laser.

In section 44(7) of the Regulations the exempt dealings define a laser as an exempt laser product with an accessible emission that does not exceed the accessible emission limits of a Class 3R laser product, as set out in AS/NZS IEC 60825.1 and an optical fibre communication system that does not exceed the hazard level 3R, as set out in AS/NZS IEC 60825.2.

Therefore, a laser with an AEL greater than the accessible emission limit of a Class 3R laser product is deemed a controlled apparatus and an optical fibre communication system where it exceeds a Hazard Level 3R as a controlled apparatus.

Because the emission level of Class 1M and Class 2M laser products may exceed the AEL for Class 3R, Class 1M and Class 2M lasers are potentially classified as controlled apparatus.

3. Class 1M lasers

A Class 1M laser is any laser product in the wavelength range from 302.5 nm to 4000 nm.

Since Class 1M is assigned to lasers where the exposure would not normally exceed the AEL of Class 1, most Class 1M lasers would not be considered to be a controlled apparatus.

The two notable exceptions to this would be where it is reasonably foreseeable that the beam may be viewed with magnifying optics like a telescope, binoculars or a microscope. Consequently the AEL may be greater than the AEL of a Class 3R laser: 

  1. where the beam is collimated with a large diameter and optics are used to focus the beam, or
  2. where the beam is highly divergent and optics are used near the laser aperture to collimate the beam.

Example: Laser diodes, fibre communication systems.

4. Class 2M lasers

Class 2M laser is any laser product in the wavelength range from 400 nm to 700 nm.

Class 2M applies only to visible lasers and assumes that a degree of protection is afforded by the aversion response (blinking and turning away). In most cases, due to the aversion response, it is not considered reasonably foreseeable that a person would deliberately view the beam for more than 0.25s. The same conditions given for Class 1M lasers apply to Class 2M lasers: unless the beam is viewed with magnifying optics it is not considered to be a controlled apparatus. 

Warning for potential hazard to the skin or eye

If the accessible emission from a Class 1M or Class 2M laser is greater than the AEL of a Class 3R as determined with a 3.5 mm diameter aperture placed at the closest point of human access, an additional warning regarding potential skin hazard and/or anterior parts of the eye hazard must be given. The following additional warning must be given on the device:

 

Warning sign that reads: AVOID EXPOSURE. LASER RADIATION IS EMITTED FROM THIS APERTURE

Hazard level 1M and 2M optical fibre communications systems (OFCS)

Hazard level refers to the potential hazard from laser emissions at any location in an end-to-end fibre optic communication system that may be accessible during use or maintenance or in the event of a failure or fibre disconnection as described in AS/NZS IEC 60825.2. The assessment of the hazard level uses the class AEL described in AS/NZS IEC 60825.1.

Hazard level 1M and Hazard level 2M OFCS may be considered to be controlled if their emission level exceeds the AEL for Class 3R and in the course of intended operations or under a reasonably foreseeable abnormal event, may lead to persons being exposed to emission in excess of the MPE mentioned in AS/NZS IEC 60825.1. Each accessible location in an extended enclosed optical transmission system will be designated by a hazard level as those for classifications in AS/NZS IEC 60825.1 and based on radiation that could become accessible and exceeds the AEL for Class 3R under reasonably foreseeable circumstances such as a fibre cable break or disconnected fibre connector. Labelling and marking requirements can be found in AS/NZS IEC 60825.2.

5. Summary

Class 1M and Class 2M lasers may be considered to be controlled if their emission level exceeds the AEL for Class 3R and in the course of intended operations or under a reasonably foreseeable abnormal event, may lead to persons being exposed to emission in excess of the MPE mentioned in AS/NZS IEC 60825.1. 

For the purposes of determining the hazard level of 1M and 2M optical fibre communications systems, the same rules apply as for Class 1M and 2M lasers.

Regulatory Guide - How to determine whether a RF source is a controlled apparatus (ARPANSA-GDE-1734)

1. Purpose

This document is provided to assist controlled persons to determine whether a radiofrequency (RF) source is classed as a controlled apparatus under the Australian Radiation Protection and Nuclear Safety Act 1998 (the Act). In particular, it clarifies conditions and defines terms used in Section 9 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations).

2. Controlled apparatus

The Group 1 table in section 4 of the Regulations defines some of the types of RF emitting devices which are classed as controlled apparatus. 

The following are examples of RF devices:

  • a magnetic field non-destructive testing device
  • an induction heater or induction furnace
  • an industrial radiofrequency heater or welder 
  • a radiofrequency plasma tube
  • microwave or radiofrequency diathermy equipment
  • an industrial microwave or radiofrequency processing system

More explanatory examples of the above listed RF emitting devices can be found in Appendix 1.

Note: In section 44 (7) of the Regulations exempt dealings for the following RF emitting devices:

  • radar equipment used for detection and ranging
  • radiofrequency equipment used for communications
  • Klystron

3. Criteria to be satisfied

Section 9 of the Regulations consists of two separate criteria, both of which must be fulfilled for the apparatus to be classed as controlled apparatus. 

The first criterion paragraph 9(1)(b) concerns source emission. It is fulfilled if the apparatus produces non-ionising radiation that could lead to a person being exposed to radiation levels exceeding the non-ionizing radiation exposure limits. For RF the relevant standard referred to in section 4 is Radiation Protection Standard for Limiting Exposure to Radiofrequency Fields – 100 kHz to 300 GHz (RPS S-1). This document specifies reference levels which have been derived from the basic restriction levels. The reference levels have been chosen as they are based on quantities that are easy to measure and compliance with the reference levels will ensure compliance with the basic restrictions. See Appendix 2 for more details and extracts from RPS S-1.  

Some of the apparatus (for example induction heaters) also generate electric and magnetic fields at 50/60 Hz. In this case the exposure limits referred to in section 4 are in the ICNIRP Guidelines for Limiting Exposure to Time-Varying Electric and Magnetic Fields (1 Hz – 100 kHz). See Appendix 3 for more details and extracts from the ICNIRP Guidelines.  

The second criterion, paragraph 9(1)(c) is based on the accessibility of the source. Factors determining whether radiation above the exposure limits is accessible to persons have to be evaluated. The condition is fulfilled if excess levels of radiation are readily accessible to persons in any of the following situations: 

  • in the course of intended operations or procedures of the apparatus; or
  • as a result of a reasonably foreseeable abnormal event involving the apparatus; or 
  • as a result of a reasonably foreseeable single element failure of the apparatus; or
  • without the use of tools or other specialised equipment required to remove protective barriers or access panels.

The following procedure describes how to go through these two criteria to determine whether an RF emitting device is classed as controlled or not.

4. Radiofrequency (high frequency) and low frequency radiation

The part of the electromagnetic spectrum with high frequencies is in the range 3 kHz to 300 GHz and is referred to as radiofrequency (RF). The low frequency is in the range of 1 Hz to 100 kHz which include the 50/60 Hz electric and magnetic fields. The diagram below shows the divisions of the electromagnetic spectrum that are commonly accepted and will be used in this guide. Microwave (MW) frequency radiation is commonly used to denote a subset of RF radiation, typically at frequencies from 300 MHz to 300 GHz. 

RF and MW radiation are forms of non-ionising radiation where individual photons are not energetic enough to break chemical bonds or remove electrons (ionisation). Ultraviolet, visible and infrared light are other forms of non-ionising radiation.

Reference Documents

  • Radiation Protection Standard for Limiting Exposure to Radiofrequency Fields – 100 kHz to 300 GHz (2021), ARPANSA Radiation Protection Series S-1 (RPS S-1). 

    The ARPANSA RF Standard sets limits for human exposure to RF EMR in the frequency range 100 kHz to 300 GHz. The Standard also includes requirements for management of risk in occupational exposure and measures for protection of the general public together with additional information on measurement and assessment of compliance. Extracts from this document can be found in Appendix 2.
     
  • ICNIRP Guidelines for Limiting Exposure to Time-Varying Electric and Magnetic Fields 1Hz-100 kHz (2010), Health Physics 99(6):818-836

    The International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines are aimed at preventing the established health effects resulting from exposure to ELF EMF. The ICNIRP ELF guidelines are consistent with ARPANSA’s understanding of the scientific basis for the protection of the general public and workers from exposure to ELF EMF. Extracts from this document can be found in Appendix 3.

Definitions 

Exposure limits – Elimit: are defined in terms of basic restrictions for occupational and general public exposure as specified in RPS S-1 and the ICNIRP Guidelines. Different exposure limits apply for occupational exposure and exposure to the general public.

Controlled apparatus (non-ionising) as defined in the Act: an apparatus prescribed by the regulations that produces harmful non-ionising radiation when energised.

Procedure for determining controlled apparatus

This procedure (as illustrated by the flow chart below) will assist you to determine whether your apparatus is controlled or not.  

This procedure (as shown in the flow chart below) will assist you to determine whether your apparatus is controlled or not.  

1. A prescribed apparatus that produces non-ionizing radiation that could lead to a person being exposed to radiation levels exceeding the non-ionizing radiation exposure limits. For example, if the apparatus is one of the devices stated in Section 1 Controlled apparatus. 

2. If there is a reasonably foreseeable abnormal event that could lead to a person being exposed to radiation levels in excess of the maximum exposure level, as specified in RPS S-1 or the ICNIRP Guidelines and reproduced in Appendix 2 and Appendix 3, the apparatus is classed as controlled apparatus. Examples of reasonably foreseeable abnormal events are possible exposure during normal maintenance, easy overriding of an interlock, entry into exclusion zones etc.   

3. If there is a reasonably foreseeable single element failure of the apparatus that would lead to a person being exposed to levels above the maximum exposure level, then the apparatus is classed as controlled apparatus. An example of this is a malfunctioning interlock. 

4. If the apparatus is enclosed the possibility of removal of the access panels or protective barriers has to be assessed. If there is no enclosure, choose no, and go to the next step. If a person can be exposed to levels above the maximum exposure level when removing protective barriers or access panels that do not require the use of tools or other specialized equipment, the apparatus is classed as controlled apparatus. 

5. Estimate the exposure level that a person could receive in the course of intended operations and procedures, ELop. The distance to the unit during intended operations should be estimated and the expected exposure level calculated or measured. The attenuation provided by any fixed shields should be taken into account. 

Compare with the exposure limits (Elimit) as specified in RPS S-1 or ICNIRP Guidelines.  

If     ELop > Elimit    then the apparatus is classed as controlled apparatus

If     ELop < Elimit     then the apparatus is not classed as controlled apparatus

Appendix 1: Examples of RF emitting apparatus 

1. Induction heater 

Definition: A heater that uses an induced electric current to produce heat.

Description: In an induction heater a conducting material is heated by induction of an electric current in the object to be heated. The resistance of the metal leads to heating. An induction heater consists of an electromagnet through which a high-frequency alternating current is passed. Heat can also be generated by magnetic hysteresis losses.  

Induction heating provides a controllable and localized method of heating without contact between the heater and the components. Typical uses for induction heaters are heat treatment of metals, hardening of steel, annealing, bonding, curing and forging. A typical induction heater is shown below in Figure 2 and induction heating of a metal bar is shown in Figure 3.

Operating frequencies range from 50/60 Hz to over 1 MHz. Induction welders and induction solders are types of induction heaters and are included in the above category. 

2. Induction furnace

Definition: A furnace that uses an induced electric current to heat a metal to its melting point.

Description: An induction furnace uses induction to heat a metal to its melting point. The heating mechanism is the same as in the induction heater. Common metals that are melted are iron, steel, copper, aluminium and precious metals. Melting and mixing rates can be controlled by selecting and varying the frequency and power. A picture of an induction furnace is shown in Figure 4.

3. Industrial radiofrequency heater 

Definition: A heating device in which heat is generated through a radiofrequency field. Industrial signifies that the apparatus is not used for domestic applications. 

Description: The frequency of operation of RF heaters is in the range 10 MHz – 100 MHz, with output powers up to 100 kW. Common frequencies are 13.56 MHz, 27.12 MHz and 40.68 MHz. These frequencies have been designated to prevent interference with communications equipment.

RF heaters are used to heat, melt, dry or cure dielectric materials (insulators or poor conductors that can be polarized by an applied electric field). Plastic, glue and rubber are electrical and thermal insulators and consequently difficult to heat using conventional methods. These materials are well suited for heating with an RF heater. This is in contrast to induction heaters (defined in the previous section) which operate at lower frequencies and are used to heat materials which are good conductors of electricity. RF heaters can be used in industrial drying processes and are then often called RF dryers.

4. Industrial radiofrequency welder 

Definition: A heating device in which heat is generated through a radiofrequency field and the heat is used to weld the material. Industrial signifies that the apparatus is not used for domestic applications. 

Description: The heating mechanism is the same in an RF welder as in an RF heater. The material (often plastic) is heated to its melting point and the work pieces are joined together. RF welders are sometimes called RF sealers. An example of a RF welder is shown in Figure 5.

5. Radiofrequency plasma tube

Definition: A tube containing plasma which is created by a radiofrequency field.  

Description: An RF generator is attached to the RF tube and is used to generate the plasma. The tube typically contains a gas or a mixture of gases. As the gas is ionized, free electrons are accelerated in the field and collide with the atoms thereby exciting the atoms. As the atoms are de-excited photons are emitted resulting in visible or ultraviolet emission. A picture of an RF plasma tube is shown in Figure 6. Common frequencies are 13.56 MHz and 2.45 GHz.

6. Microwave or Radiofrequency (RF) diathermy equipment

Definition: Microwave diathermy equipment uses electromagnetic energy in the microwave frequency range (300 MHz to 300 GHz) for therapeutic purposes.

Whilst, RF diathermy equipment uses electromagnetic energy in the frequency range (3-30 MHz) for therapeutic purposes.

In Australia the only approved frequency for microwave diathermy treatment is 2450 MHz.  

RF diathermy is sometimes referred to as shortwave diathermy. In Australia the only approved frequency for RF diathermy is 27.12 MHz. A picture of a diathermy unit is shown in Figure 7.

Note: Microwave and RF diathermy are not used very much nowadays and very few licence holders have this apparatus. In both microwave diathermy and RF diathermy heating of muscular tissue is performed for therapeutic reasons. In surgical diathermy a high-frequency electric current is made to pass through the body between two contact electrodes. The frequency is lower than for RF diathermy, typically 0.5–3 MHz. Surgical diathermy is not included in the above definition for microwave and radiofrequency diathermy equipment.

7. Industrial microwave processing system

Definition: A system where energy in the form of microwaves is used for heating or drying. Industrial signifies that the apparatus is not used for domestic applications.  

Common microwave frequencies are 915 MHz, 2.45 GHz and 5.8 GHz. An industrial microwave is considered an industrial microwave processing system.

8. Industrial radiofrequency processing system

Definition: A system where energy in the form of radiofrequency waves is used for heating or drying. Industrial signifies that the apparatus is not used for domestic applications.  

The most common RF frequencies are 13.56 MHz, 27.12 MHz and 40.68 MHz. Note that the definition for an industrial RF processing system is similar to the definition for an industrial RF heater. Typically an industrial RF processing system is a large enclosed unit used for large scale heating or drying (see Figure 9).

Radiofrequency and microwave processing systems are frequently used for heating and drying of materials such as paper, ceramics, food and plastics. Heating through RF and microwave is fast compared with conventional heating mechanisms which makes them a preferred option for pasteurization and sterilization. Microwave heating is a common choice in a laboratory environment. The heating mechanism is the same in RF heating, the only difference being the lower frequency. The selection of RF or microwave heating depends on the physical properties of the process. The penetration depth is greater for RF (longer wavelength) which can therefore be more suited for larger scale systems. RF systems also have a greater uniformity of heating.

Appendix 2: Extracts from RPS S-1 Limiting Exposure to RF Fields – 100 kHz to 300 GHz (2021)

General information

The standard includes:

  • mandatory basic restrictions for both occupational and general public exposure involving the whole body and also for exposure over localised areas of the body
  • indicative reference levels for measurable quantities derived from the basic restrictions
  • approaches for verification of compliance with the standard
  • requirements for management of risk in occupational exposure and measures for protection of the general public 

Basic Restrictions:

Mandatory limits on exposure to RF fields are based on established health effects and are termed ‘basic restrictions’. Depending on the frequency the physical quantities used to specify the basic restrictions are induced electric field (Eind), specific absorption rate (SAR), specific energy absorption (SA) and absorbed energy density (Uab). These quantities are often impractical to measure. Therefore reference levels are measured as an alternative means of showing compliance with the mandatory basic restrictions.

Reference Levels:

Reference levels using quantities that are more practical to measure have been developed. The reference levels have been conservatively formulated such that compliance with the reference levels will ensure compliance with the basic restrictions. Provided that all basic restrictions are met and adverse effects can be excluded, the reference levels may be exceeded. Hence the reference levels have been conservatively formulated such that compliance with the reference levels will ensure compliance with the basic restrictions. The relevant reference level quantities are incident electric field strength (Einc), incident magnetic field strength (Hinc), incident power density (Sinc), plane-wave equivalent incident power density (Seq), incident energy density (Uinc), and plane-wave equivalent incident energy density (Ueq), all measured outside the body, and electric current (I) inside the body.

Reference levels are given for occupational exposure and exposure to the general public. These groups are distinguished by their potential level of exposure. 

In the extract from RPS S-1 below, reference levels are specified in Tables 4 - 7 and have been set to protect against effects associated with:

  • Table 4 whole body exposure (averaged over 30 minutes) 
  • Table 5 local exposure (averaged over 6 minutes)
  • Table 6 brief local exposure (integrated over intervals between >0 and <6 minutes)
  • Table 7 instantaneous local exposure (peak instantaneous field strength) 

For further information see Radiation Protection Series S-1.

Notes:

  1. ‘NA’ signifies ‘not applicable’ and does not need to be taken into account when determining compliance. 
  2. ‘ES’ signifies that no reference level is available, as it would be greater than the reference level for spatial peak and temporal peak field strengths based on electrostimulation effects shown in Table 7. 
  3. fM is frequency in MHz. 
  4. Sinc, Einc and Hinc are to be averaged over 30 minutes, over the whole-body space.

  5. For frequencies of 100 kHz to 30 MHz, regardless of the far-field/near-field zone distinctions, compliance is demonstrated if neither Einc nor Hinc exceeds the above reference level values. 
  6. For frequencies of >30 MHz to 2 GHz: a) within the far-field and radiating near field zones: compliance is demonstrated if either Sinc, Einc or Hinc, does not exceed the above reference level values (only one is required); Seq derived from either Einc or Hinc may be substituted for Sinc; b) within the reactive near-field zone: compliance is demonstrated if both Einc and Hinc do not exceed the above reference level values; Sinc cannot be used to demonstrate compliance, and so basic restrictions must be assessed. 
  7. For frequencies of >2 GHz to 300 GHz: a) within the far-field and radiating near field zones: compliance is demonstrated if Sinc does not exceed the above reference level values; Seq derived from either Einc or Hinc may be substituted for Sinc; b) within the reactive near-field zone, reference levels cannot be used to determine compliance, and so basic restrictions must be assessed.

Notes:

  1. ‘NA’ signifies ‘not applicable’ and does not need to be taken into account when determining compliance. 
  2. ‘ES’ signifies that no reference level is available, as it would be greater than the reference level for spatial peak and temporal peak field strengths based on electrostimulation effects shown in Table 7. 
  3. fM is frequency in MHz; fG is frequency in GHz. 
  4. Sinc, Einc and Hinc are to be averaged over 6 minutes, and where spatial averaging is specified in Notes 6-7, over the relevant projected body space. Temporal and spatial averaging of each of Einc and Hinc must be conducted by averaging over the relevant square values (see ICNIRP guidelines for limiting exposure to electromagnetic fields (100 kHz to 300 GHz), Health Physics, 118(5):483–524 for details) see link International best practice - non-ionising radiation safety | ARPANSA to the ICNIRP website.
  5. For frequencies of 100 kHz to 30 MHz, regardless of the far-field/near-field zone distinctions, compliance is demonstrated if neither peak spatial Einc nor peak spatial Hinc, over the projected whole-body space, exceeds the above reference level values. 
  6. For frequencies of >30 MHz to 6 GHz: a) within the far-field and radiating near field zones, compliance is demonstrated if one of peak spatial Sinc, Einc or Hinc, over the projected whole-body space, does not exceed the above reference level values (only one is required); Seq derived from either Einc or Hinc may be substituted for Sinc; b) within the reactive near-field zone: compliance is demonstrated if both Einc and Hinc do not exceed the above reference level values; Sinc cannot be used to demonstrate compliance; for frequencies >2 GHz, reference levels cannot be used to determine compliance, and so basic restrictions must be assessed.
  7. For frequencies of >6 GHz to 300 GHz: a) within the far-field and radiating near field zones, compliance is demonstrated if Sinc, averaged over a square 4 cm2 projected body surface space, does not exceed the above reference level values; Seq derived from either Einc or Hinc may be substituted for Sinc; b) within the reactive near-field zone, reference levels cannot be used to determine compliance, and so basic restrictions must be assessed. 
  8. For frequencies of >30 GHz to 300 GHz, exposure averaged over a square 1-cm2 projected body surface space must not exceed twice that of the square 4 cm2 Sinc restrictions.

Notes:

  1. ‘NA’ signifies ‘not applicable’ and does not need to be taken into account when determining compliance. 
  2. fM is frequency in MHz; fG is frequency in GHz; t is the exposure time interval in seconds, such that exposure from any pulse, group of pulses, or subgroup of pulses in a train, as well as from the summation of exposures (including non-pulsed RF electromagnetic fields), delivered in t seconds, must not exceed these reference level values for any time 0 < t < 360 s. 
  3. Uinc is to be calculated over time t, and where spatial averaging is specified in Notes 5-7, over the relevant projected body space. 
  4. For frequencies of 100 kHz to 400 MHz, >0 to <6-minute restrictions are not required and so reference levels have not been set. 
  5. For frequencies of >400 MHz to 6 GHz: a) within the far-field and radiating near field zones: compliance is demonstrated if peak spatial Uinc, over the projected whole-body space, does not exceed the above reference level values; Ueq derived from either Einc or Hinc may be substituted for Uinc; b) within the reactive near-field zone, reference levels cannot be used to determine compliance, and so basic restrictions must be assessed. 
  6. For frequencies of >6 GHz to 300 GHz: a) within the far-field or radiative near-field zone, compliance is demonstrated if Uinc, averaged over a square 4 cm2 projected body surface space, does not exceed the above reference level values; Ueq derived from either Einc or Hinc may be substituted for Uinc; b) within the reactive near-field zone, reference levels cannot be used to determine compliance, and so basic restrictions must be assessed. 
  7. For frequencies of >30 GHz to 300 GHz: exposure averaged over a square 1cm2 projected body surface space must not exceed 275/fG0.177 x 0.72(0.025+0.975[t/360]0.5) kJ/m2 for occupational and 55/fG0.177 x 0.72(0.025+0.975[t/360]0.5) kJ/m2 for general public exposure.

(V/m)
Incident H-field strength Hinc
(A/m)
Occupational 100 kHz – 10 MHz 170 80
General Public 100 kHz – 10 MHz 83 21

Notes: 

  1. Regardless of the far-field/near-field zone distinction, compliance is demonstrated if neither the temporal nor spatial peak Einc or Hinc, over the space occupied by the body, exceeds the above reference level values. 

The figures for occupational and general public reference levels for whole body and local exposure to RF electromagnetic fields as specified in tables 4 and 5 can be found in RPS S-1 Schedule 1.

Reference levels for limb currents

Limb current reference levels have been set to account for effects of grounding near human body resonance frequencies that might otherwise lead to reference levels underestimating exposures within tissue at certain RF electromagnetic field frequencies (averaged over 6 minutes – see Table 8) Limb current reference levels are only relevant in exposure scenarios where a person is not electrically isolated from a ground plane.

Table 8: Reference levels for current induced in any limb averaged over 6 minutes at frequencies between 100 kHz and 110 MHz

Exposure Scenario Frequency range Current I (mA)
Occupational 10 MHz – 110 MHz 100
General Public 10 MHz – 110 MHz 45

Notes: 

  1. Current intensity values must be determined by averaging over the relevant square values (see ICNIRP guidelines for limiting exposure to electromagnetic fields (100 kHz to 300 GHz), Health Physics, 118(5):483–524 for details), the document can be downloaded from the ARPANSA website link International best practice - non-ionising radiation safety | ARPANSA to the ICNIRP website.
  2. Limb current intensity must be evaluated separately for each limb. 
  3. Limb current reference levels are not provided for any other frequency range. 
  4. Limb current reference levels are only required for cases where the human body is not electrically isolated from a ground plane. 

Tables 4 to 8 specify averaging and integrating times of the relevant exposure quantities to determine whether personal exposure level is compliant with the Standard. These averaging and integrating times are continuous periods.

Guidance for contact currents

Exposure due to contact currents is indirect, in that it requires an intermediate conducting object to transduce the field. This makes contact current exposure unpredictable, due to both behavioural factors (e.g., grasping versus touch contact) and environmental conditions (e.g., configuration of conductive objects), and reduces this Standard’s ability to protect against them. Accordingly, the ICNIRP guidelines and the Standard do not provide restrictions for contact currents, and instead provide ‘guidance’ to assist those responsible for transmitting high-power RF fields to understand contact currents, the potential hazards, and how to mitigate such hazards. 

In determining the likelihood and nature of the hazard due to potential contact current scenarios, ICNIRP views the following as important for the Responsible Person in managing risk associated with contact currents within the 100 kHz to 110 MHz region. 

(a) Contact current thresholds for reversible, mild pain, for adults and children, are likely to be approximately 20 mA and 10 mA respectively. 

(b) Contact current magnitude will increase as a function of field strength and is affected by conducting-object configuration such as the proximity to the original source and the angular alignment to the original source. 

(c) Risk of contact current hazards can be minimized by training workers to avoid contact with conducting objects, but where contact is required, the following factors are important: 

i.    Large conducting objects should be connected to ground (grounding). 

ii.    Workers should make contact via insulating materials or PPE (e.g., RF protective gloves). 

iii.    Reducing or removing the RF power at the original source can eliminate the risk. 

iv.    Workers should be made aware of the risks, including the possibility of ‘surprise’, which may impact on safety in ways other than the direct impact of the current on tissue (for example, by causing accidents when working at heights).

Regulatory Guide - UV emitting apparatus case studies (ARPANSA-GDE-1748)

Introduction

This document is provided to assist applicants and licence holders assess UV emitting apparatus. It may also be useful for non-licence holders to gain an understanding of the hazard of some typical UV emitting apparatus. It contains case studies of apparatus that have been assessed by ARPANSA. 

Read this guide in conjunction with Regulatory Guide: Determining whether a UV source is a controlled apparatus.

If you have any questions on how to evaluate your specific apparatus please contact your regulatory officer or send an email to: licenceadmin@arpansa.gov.au.

Note: Subsection 44(7) of the Regulations exempts dealings with the following UV emitting apparatus:

  • an artificial optical source emitting ultraviolet A radiation (315 – 400 nm)
  • a completely enclosed apparatus containing an ultraviolet radiation light source (e.g., a spectrophotometer)
  • a biological safety cabinet (laminar flow or biohazard) with a failsafe interlocking system
     

Contents

Apparatus Outcome
1. Biological safety cabinet – Example 1 Controlled apparatus
2. Biological safety cabinet – Example 2 Not controlled apparatus
3. High-performance liquid chromatography (HPLC) Not controlled apparatus
4. Pen-ray Mercury lamp Controlled apparatus
5. Spectrophotometer Not controlled apparatus
6. Transilluminator Controlled apparatus
7. UV light box Controlled apparatus
8. Water steriliser – Example 1 Controlled apparatus
9. Water steriliser – Example 2 Not controlled apparatus

1. Biological safety cabinet – Example 1

 

biological safety cabinet

Details of the apparatus 

  • The biological safety cabinet emits at a wavelength of 254 nm, which is in the UVC region (180 – 280 nm). It is a germicidal lamp which means that the emission levels will be well above the exposure limits. 
  • The lower access panel can be taken off while the UV lamp is energized.
  • There is no interlock or the interlock can be overridden.

Assessment

During intended operations or procedures the exposure limits will not be exceeded, as the window and access panel will protect the user. The UV light is only used between procedures for disinfecting. It should not be used while samples are being handled.  

It is reasonably foreseeable that a person could remove the access panel while the UV light is on and receive an exposure. 

This biological safety cabinet is classed as controlled apparatus

2. Biological safety cabinet – Example 2

 

biological safety cabinet

Details of the apparatus 

  • The biological safety cabinet emits UV light at 254 nm (UVC). It is a germicidal lamp which means that the emission levels will be well above the exposure limits.
  • The fluorescent lamps and UV light cannot work simultaneously as they are electronically interlocked.
  • While the unit is in UV mode the sliding window cannot be opened.
  • UV light cannot be turned on while the sliding door is open. 
  • If a fault occurred and the window could be opened electronically or manually, an interlock will cut the UV emission. The interlock is failsafe (meaning that if it should fail the UV emission will terminate) and hard to override.

Assessment

During intended operations or procedures the exposure limits will not be exceeded. 

Due to the robust failsafe, interlock there is no reasonably foreseeable abnormal event that would expose a person to levels above the exposure limits. 

As the interlock is failsafe there is no reasonably foreseeable single element failure that would expose a person to levels above the exposure limits. 

This biological safety cabinet is not classed as controlled apparatus 

Comment 

This assessment is based on the above criteria for a biological safety cabinet. Most standard older biological safety (laminar flow/biohazard) cabinets containing a UV source are classed as controlled apparatus. Please contact an ARPANSA regulatory officer to discuss if you have a biological safety cabinet that you believe is not classed as controlled apparatus on the same grounds as in the example above.

3. High-performance liquid chromatography (HPLC)

 

high-performance liquid chromatography

Details of the apparatus 

  • The UV light source is completely enclosed
  • Low UV emission

Assessment

During intended operations or procedures the exposure limits will not be exceeded. 

It is not reasonably foreseeable that a person could access the UV source and receive exposures above the exposure limit. 

A person cannot remove access panels without use of tools or specialised equipment. 

The apparatus is not classed as controlled apparatus

Comment

If a unit is a standard HPLC with properties similar to the one above it is automatically classed as not controlled. There is no need to assess it against the regulatory guide.

4. Pen-Ray Mercury lamp

 

pen ray mercury lamp

Source: http://uvp.com/mercury.html

Details of the apparatus

  • UV lamp used in a number of applications in laboratories (sterilisation, fluorescent inspection, wavelength calibration etc.)  
  • Lamp emits Mercury spectral lines with the primary emission at 254nm.
  • Typical intensity:
    • 254 nm @ 20 mm distance = 4700 µW/cm2 = 47 W/m2 (UVC)
    • 365 nm @ 20 mm distance = 215 µW/cm2 = 2.15 W/m2 (UVA)

Assessment

Skin and Eye UVR exposure:

Calculate the effective irradiance according to RPS 12:

At 20 mm:

 

Equation

 

Equation

       
At 20 cm: 

 

Equation

It is reasonably foreseeable that someone would be exposed for more than 2 minutes at 20 cm distance or more than 1.3 seconds at 20 mm distance. This means that the UVR exposure limit could be exceeded.

Eye UVA (315 – 400 nm) exposure:

At 20 mm: E365nm=  2.15 W/m2

 

Equation

 

At 50 cm:

The exposure limit at 50 cm  

 

Equation

Maximum UVA exposure for the eyes will not be exceeded. The exposure to the skin will be the limiting factor.  

It is reasonably foreseeable that a person could be exposed to levels above the exposure limit.

The apparatus is classed as controlled apparatus

5. Spectrophotometer

 

spectrophotometer

Details of the apparatus 

  • The UV light source is enclosed during operation
  • Low UV emission

Assessment

During intended operations or procedures the exposure limits will not be exceeded. 

It is not reasonably foreseeable that a person could access the UV source and receive exposures above the exposure limit. 

The apparatus is not classed as controlled apparatus

Comment

If a unit is a standard spectrophotometer with properties similar to the one above it is automatically classed as not controlled. There is no need to assess it against the regulatory guide.

6. Transilluminator

 

transilluminator

 

transilluminator

Details of the apparatus 

  • The emission of transilluminators is typically 254 nm, 312 nm or 366 nm.
  • Transilluminators are powerful sources of UV radiation. Emission levels are above exposure limits. Transilluminators, used in research can be a significant source of occupational exposure to UVR. Hands, arms, face and eyes are likely sites of injury. Working unprotected for even a few minutes can cause injury.

Assessment

Reasonably foreseeable abnormal events where exposure limits could be exceeded are:

  • shielding is removed or non-existent
  • PPE is not worn or is not appropriate

Both transilluminators are classed as controlled apparatus

Comment 

There have been a number of incidents where the user of a transilluminator developed erythema because appropriate PPE was not used and a shield was not present.   

7. UV light box

 

uv light box

 

uv light box

Details of the apparatus 

  • Homemade units 
  • Manual switches turns UV source on and off
  • Intensity levels unknown
  • There is no interlock or fixed shielding

Assessment

It is reasonably foreseeable that someone might place their hand in the box while the UV source in on. If the levels are high enough the exposure levels could be exceeded. 

The apparatus is classed as controlled apparatus 

Comment 

If emission levels are measured and found to be low (no reasonably foreseeable abnormal event where a person would be exposed to levels above the exposure limit) the apparatus is not controlled.

8. Water steriliser – Example 1

 

water steriliser

Details of the apparatus 

  • Water steriliser where UV lamp is used to kill bacteria as the water flows past. 
  • Germicidal action which means that emission levels are high (primarily UVC – 254 nm). 
  • UV light is leaking out from the back of the unit. The unit is completely enclosed apart from this opening. The emission levels of the escaping UV light have not been quantified. 
  • The enclosure is interlocked. 

Assessment

We can assume that the intensity of the escaping light is low so that during intended operations or procedures the exposure limits will not be exceeded (a person will not normally be close to the unit). 
It is reasonably foreseeable that a person could hold their hand close to the unit and be exposed to the escaping light. As we do not know the intensity of the escaping light we make the conservative assumption that the exposure limit can be exceeded. 

The apparatus is classed as controlled apparatus

9. Water steriliser – Example 2

 

water steriliser

Details of the apparatus 

  • Water steriliser where UV lamp is used to kill bacteria as the water flows past. 
  • The emission of the UV light is at 254 nm (UVC). Germicidal action which means that emission levels are high. 
  • The unit is fully enclosed and the housing is not interlocked.  
  • A screwdriver is needed to open the housing. 

Assessment

During intended operations or procedures the exposure limits will not be exceeded as the source is completely enclosed.

A reasonably foreseeable abnormal event that would expose a person to levels above the exposure limit could be exposure during maintenance when the UV lamp is replaced. The standard operating procedure for changing the lamp illustrates that the lamp is completely enclosed in a special housing, and that the power has to be switched off before you can access the UV lamp. From this it is concluded that there is no risk of exposure during the process of changing the lamp. 

Excess levels of radiation are not accessible under a reasonable foreseeable single element failure of the apparatus and the source cannot be accessed without the use of tools or specialised equipment. 

The apparatus is not classed as controlled apparatus

Regulatory Guide - Applying for a source licence (or amendment) (ARPANSA-GDE-1740)

Associated forms

Selecting the correct application form

There are 3 source licence application forms - the choice of form depends on the hazard of the source(s): Group 1 sources are considered low hazard, Group 2 sources are considered medium hazard and Group 3 sources are considered high hazard. Section 4 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations) describes the types of sources in each group and this will assist you to select the correct application form. 

Completing the application form

Nominee

If the applicant is physically removed from the source dealing, such that they cannot demonstrate effective control, the name and contact details of a person more directly in control of the source dealing must be provided. This nominee must be in effective control of the sources. Generally, the nominee will be the manager of a division or agency’s operation at the site of the proposed activity or, in the case of mobile or portable devices, where the devices are usually stored. Other nominees may also be acceptable where the hazards of the activity are low and only minimal control is required. If a nominee is appointed, an organisational chart should be provided showing the relationship of the nominee to the applicant and end users.

Radiation Safety Officer (RSO)

This is an individual appointed by the applicant to supervise radiation safety in relation to the sources for which the licence is sought. This person must be technically competent in radiation protection matters relevant to all sources, including non-ionising radiation sources if these are part of the application. Evidence of competency should be included. If there is more than one radiation safety officer, the details of other radiation safety officers should also be provided.

Note 2: An RSO may not always be required. Applicants should refer to Regulatory Guide: Plans and Arrangements for Managing Safetyor contact ARPANSA.

An explanation of terms and required information appears in the first worksheet. The completed SIW must be submitted with the application.

Section D: Plans & arrangements for managing safety 

The applicant must have plans and arrangements for managing sources to ensure the health and safety of people and protection of the environment. These should be a comprehensive program of policies and procedures that demonstrate how radiation safety will be ensured. The content of these plans and arrangements will vary depending on the hazard and complexity of the sources to be dealt with. 

There is no pre-determined format for supplying this information. The applicant may either describe the plans and arrangements on the application form or may reference suitable organisational documents. If the latter option is taken, the applicant must clearly indicate on the application form where the relevant information can be found within accompanying documents.  

A brief description of what is expected in plans and arrangements is provided below. For more detailed information, refer to Regulatory Guide: Plans and Arrangements for Managing Safety

Applicants should identify the codes and standards relevant to the proposed dealing and describe how these will be implemented or taken into account in managing the safety of sources. This information may be incorporated into Section D of the licence application.  

Codes and standards applicable to each kind of source can be found here. These codes and standards will become conditions of licence should the application be approved. 

ARPANSA publishes information about international best practice (IBP) with links to international codes and standards that may be relevant to the proposed dealing. The applicant is advised to consider these where relevant. 

Depending on the type of source, the applicant may be required to address some or all of the following:

Effective Control Arrangements

Provide information to demonstrate how the applicant or nominee will maintain control over the particular dealings for which a licence is sought. The arrangements should cover such things as organisational arrangements, management systems and resources.

Safety Management Plan

Describe the administrative arrangements for managing safety. These arrangements may be minimal, where only low hazards are involved, but will be more extensive for dealings of higher hazard or complexity. The safety management plan should cover things such as safety culture, safety of premises and equipment, competency and training, incidents, auditing and record keeping. 

Radiation Protection Plan

Radiation protection policies and procedures should be set out in a radiation safety manual and in specific operating procedures. Guidance on the content of such a manual is provided in chapter 3 of RPS C-1 Code for Radiation Protection in Planned Exposure Situations

The radiation protection plan should cover issues such as principles of radiation protection, planning and design of the workplace, classification of work area, local procedures, radiation monitoring of individuals and the workplace and protection of the environment.  

Where sources are to be used for medical purposes, the plans and arrangements should address the requirements of RPS C-5 Code for radiation protection in medical exposure  and associated safety guides for diagnostic and interventional radiology, radiotherapy, and nuclear medicine; in particular, addressing optimisation of exposure and radiation protection of the patient. 

In addition, the applicant is responsible for ensuring that arrangements are implemented for the appointment of a suitably qualified radiation safety officer and/or radiation safety committee as appropriate. Information should be provided about the qualifications and experience of such persons and the arrangements in place for their continued competency. 

Radioactive Waste Management Plan

A full description and anticipated amounts of any radioactive wastes, including discharges arising from the proposed dealing and the arrangements for the safe handling, treatment, storage and disposal of any such waste should be set out in a radioactive waste management plan. 

Refer to RPS C-6 Code for Disposal of Waste by the User

Ultimate Disposal or Transfer Plan

Provide a plan for the ultimate transfer or disposal of sources. Copies of documented undertakings by other organisations to accept sources when no longer required should be provided where possible. Applicants should note that after a licence is issued, section 65 of the Regulations applies to the disposal and transfer of sources. 

Note 3: Stricter requirements apply to security enhanced sources - applicants should refer to the RPS 11 Code of Practice for Security of Radioactive Sources.

Security Plan

Describe the arrangements for the security of sources to prevent theft, damage or unauthorised access. These arrangements should ensure that control of sources is not relinquished without appropriate approvals required by the Regulations and conditions of licence.  The plan should provide for periodic inventory checks to confirm that all sources are secure and in their assigned location.

Refer to RPS 11 Code of Practice for Security of Radioactive Sources. Compliance with this code is mandatory for security enhanced sources - in particular the need for an approved security plan.  

Note 4: A security enhanced source is a radioactive source or aggregation of sources assigned Security Category 1, 2 or 3 when using the methodology set out in Schedule B of RPS 11.   

Emergency Plan

Emergency arrangements must be developed for all foreseeable emergencies such as dispersion of materials, overexposure of operators, or theft or loss of controlled material. The arrangements should include: the responsibilities of all parties in the event of an emergency; contact arrangements; emergency procedures; emergency equipment; and reporting arrangements. Where necessary, arrangements for involving external agencies such as police and other emergency services should be included.

The plan should include arrangements for testing the emergency arrangements through regular reviews and exercises and rectifying any deficiencies found in the emergency plans. 

Refer to RPS G-3 Guide for Radiation Protection in Emergency Exposure Situations.

Section E: Matters to be taken into account by the CEO

Subsection 33(3) of the Australian Radiation Protection and Nuclear Safety Act 1998 (the Act) requires the CEO to take into account international best practice in relation to radiation protection and nuclear safety when making a decision whether to issue a source licence. The CEO must also take into account the matters prescribed in section 53 of the Regulations. Provide information on these matters in Section E for the CEO to consider.

International best practice in radiation protection and nuclear safety 

Describe how international best practice (IBP) has been considered in relation to the facility relevant to the type of authorisation sought. 

Each element of the proposed activity should be researched to determine what can be regarded as IBP. Undertaking research and benchmarking exercises are a useful way to establish IBP.   

Implementation of relevant national and international codes and standards is considered a demonstration of best practice. 

Refer to the International Best Practice page for further information. 

Undue risk 

Provide information to demonstrate that sources can be dealt with without undue risk to the health and safety of people and the environment. This should include evidence that the radiation risks to people and the environment arising from the proposed dealing have been fully assessed, including the probability and magnitude of potential exposures arising from incident scenarios and abnormal occurrences.  

Net benefit 

Provide information to demonstrate that dealing with sources produces sufficient benefit to individuals or to society to offset the radiation harm that it might cause, taking into account societal, economic and other relevant factors; that is, the applicant must justify the dealing and demonstrate a net benefit from it.

Optimisation of protection

Provide information to demonstrate that protection has been optimised. The level of protection should be the best under prevailing circumstances and should provide for an adequate margin of benefit over harm. Information should show that the likelihood of incurring exposures, the number of people exposed, and the magnitude of exposures are as low as reasonably achievable, having regard to economic and societal factors. Information such as actual dose information, including dosimeter readings and surveys or sample dose calculations or both could be provided for this purpose.    

Technical, human and organisational factors

Provide information to demonstrate that interactions between technical, human and organisational factors have been considered in the management of safety.  

Human factors involve understanding human capability and limitations in operational and maintenance roles relating to sources. There are a variety of human factors assessments that can be used to both understand and demonstrate the management of safety critical risks. 

Organisational factors are aspects of the organisation that facilitate performance (in safety), e.g. culture, safety management systems, leadership, resilience, defence-in-depth. Organisational factors can be addressed through a variety of self-reflective practices and systemic design.

Technical factors include the design, operation and maintenance of equipment, machinery and tools. It is important the organisation thinks about the ways in which humans will respond, adapt, and learn from organisational and technical factors.

Guidance on what interactions to consider and questions to ask can be found in the Holistic Safety Guide and Holistic Safety Guide (sample questions).

Capacity to comply 

Provide information to demonstrate that the applicant has the capacity to comply with the Regulations and licence conditions that would be imposed under section 35 of the Act.  

Evidence of compliance with similar legislation such as that administered by Comcare or the Australian Safeguards and Non-Proliferation Office (ASNO) may be useful for this purpose.  A current ARPANSA licence holder may refer to their compliance history.   

Provide information to demonstrate that there are sufficient financial and human resources to safely deal with sources. 

Authorised signatory 

The application must be signed by an office holder of the applicant or a formally authorised person.

International best practice in radiation protection and nuclear safety 

Describe how international best practice (IBP) has been considered in relation to the facility relevant to the type of authorisation sought. 

Each element of the proposed activity should be researched to determine what can be regarded as IBP. Undertaking research and benchmarking exercises are useful ways to establish IBP. Implementation of relevant national and international codes and standards is considered a demonstration of best practice.  

Refer to the International Best Practice page for further information.     

Undue Risk 

Provide information to demonstrate that the proposed conduct can be undertaken without undue risk to the health and safety of people and the environment. This should include evidence that the radiation risks to people and the environment arising from the proposed conduct have been fully assessed, including the probability and magnitude of potential exposures arising from incident scenarios and abnormal occurrences.  

Net benefit 

Provide information to demonstrate that the proposed conduct produces sufficient benefit to individuals or to society to offset the radiation harm that it might cause, taking into account social, economic and other relevant factors; that is, the applicant must justify the conduct and demonstrate a net benefit from it.

Optimisation of protection 

Provide information to demonstrate that protection has been optimised. The level of protection should be the best under prevailing circumstances and should provide for an adequate margin of benefit over harm. Information should show that the likelihood of incurring exposures, the number of people exposed and the magnitude of exposures are as low as reasonably achievable, having regard to economic and societal factors. Information such as actual dose information, including dosimeter readings and surveys or sample dose calculations or both could be provided for this purpose.     

Technical, human and organisational factors 

Provide information to demonstrate that interactions between technical, human and organisational factors have been considered in the management of safety. 

Human factors involve understanding human capability and limitations in operational and maintenance roles relating to the PRF. There are a variety of human factors assessments that can be used to both understand and demonstrate the management of safety critical risks. 

Organisational factors are aspects of the organisation that facilitate performance (in safety), eg. culture, safety management systems, leadership, resilience, defence-in-depth. Organisational factors can be addressed through a variety of self-reflective practices and systemic design.

Technical factors include the design, operation and maintenance of equipment, machinery and tools. It is important the organisation thinks about the ways in which humans will respond, adapt, and learn from organisational and technical factors.

Guidance on what interactions to consider and questions to ask can be found in the Holistic Safety Guide and Holistic Safety Guide (sample questions).

Capacity to Comply 

Provide information to demonstrate that there is capacity to comply with the Regulations and licence conditions that would be imposed under section 35 of the Act.  

Evidence of compliance with similar legislation such as that administered by Comcare or the Australian Safeguards and Non-Proliferation Office (ASNO) may be useful for this purpose.  A current ARPANSA licence holder may refer to their compliance history.   

Provide information to demonstrate that there are sufficient financial and human resources to safely undertake the proposed conduct.

The level of protection should be the best under prevailing circumstances and should provide for an adequate margin of benefit over harm. Information should show that the likelihood of incurring exposures, the number of people exposed and the magnitude of exposures are as low as reasonably achievable, having regard to economic and societal factors. Information such as actual dose information, including dosimeter readings and surveys or sample dose calculations or both could be provided for this purpose. 

Technical, human and organisational factors 

Provide information to demonstrate that interactions between technical, human and organisational factors have been considered in the management of safety.  

Human factors involve understanding human capability and limitations in operational and maintenance roles relating to the nuclear installation. There are a variety of human factors assessments that can be used to both understand and demonstrate the management of safety critical risks. 

Organisational factors are aspects of the organisation that facilitate performance (in safety), eg. culture, safety management systems, leadership, resilience, defence-in-depth. Organisational factors can be addressed through a variety of self-reflective practices and systemic design.

Technical factors include the design, operation and maintenance of equipment, machinery and tools. It is important the organisation thinks about the ways in which humans will respond, adapt, and learn from organisational and technical factors.

Guidance on what interactions to consider and questions to ask can be found in the Holistic Safety Guide and Holistic Safety Guide (sample questions).

Capacity to comply 

Provide information to demonstrate that the applicant has the capacity to comply with the Regulations and licence conditions that would be imposed under section 35 of the Act.  

Evidence of compliance with similar legislation such as that administered by Comcare or the Australian Safeguards and Non-Proliferation Office (ASNO) may be useful for this purpose.  A current ARPANSA licence holder may refer to their compliance history.   

Provide information to demonstrate that there are sufficient financial and human resources to safely undertake the proposed conduct. 

Authorised signatory 

The application must be signed by an office holder of the applicant or a formally authorised person. An office holder is the Secretary, Chief Executive Officer or an equivalent person of the Department or entity that is named as the applicant. Where a person authorised by an office holder of the applicant signs the application, a copy of the instrument of authorisation must be provided.

Checklist

A checklist is provided to confirm the application is complete.

Application fee

Refer to section 49 of the Regulations to determine the appropriate application fee. The fee must be received before the application can be assessed. Accepted payment methods are EFT, credit card or BPAY – please see payment methods.

Submitting your application

Send the completed application and all supporting documents to licenceadmin@arpansa.gov.au.  

Note: A version of the application suitable for public review must also be provided.  Documents for release must satisfy the Australian Government Web Accessibility guidelines.

How your application will be processed

When your application is submitted it will be examined to see if all the necessary information is included, if it is properly signed, if the correct application fee has been paid, and if a version of the application has been provided for public review. If so, you will receive an acknowledgment email. If any of the basic information is missing you will be contacted for further information or in some cases the application and fee may be returned.

As soon as practicable after receiving your application, and after confirming it is complete, the CEO is required by section 48 of the Regulations to publish a notice in a national daily newspaper and on ARPANSA’s website, stating the intention to make a decision on the application. The public version of the application will be published with the notice. The CEO will include in the notice:

  • an invitation to people and bodies to make submissions about the application 
  • a period for making submissions 
  • procedures for making submissions  

Your application will then be assigned to a regulatory officer. The regulatory officer will discuss and agree a time with you to complete the assessment. 

The regulatory officer will review all the information and consider the claims, evidence and arguments presented. Where matters require clarification, the regulatory officer will contact you or your nominee. The regulatory officer may also consider that an inspection or site visit is necessary and will contact you to arrange. 

The officer will then prepare a regulatory assessment report to document the review. The content of any submissions made by members of the public about the application will be addressed in the report. 

The assessment report will make a recommendation to the CEO about whether to issue a licence and may recommend licence conditions to be imposed under section 35 of the Act. The assessment report undergoes a rigorous review and approval process prior to being sent to the decision maker with all relevant documentation.

You will be advised in writing of the decision. The CEO may also publish a ‘statement of reasons’ for the decision on this website.  

Detailed information about how ARPANSA undertakes assessments can be found in our Review and Assessment Manual on the 'how we regulate' page.   

Under section 37 of the Act, a licence may be issued indefinitely or for a specified period. When issued a licence remains in force until it is cancelled or surrendered, or the specified period has elapsed.  

Appealing a licence decision

Section 40 of the Act describes the rights of review available to eligible persons in respect of licence decisions made by the CEO. The following decisions are reviewable:

  • to refuse to grant a licence
  • to impose conditions on a licence
  • to suspend a licence
  • to cancel a licence
  • to amend a licence 
  • not to approve the surrender of a licence
  • to issue a licence for a particular period, rather than for a longer period or indefinitely
  • not to extend the period for which a licence was issued

An eligible person in relation to a decision to refuse to grant a licence means the person who applied for the licence, and in relation to any other licence decision, it is the licence holder.

Review by the Minister

Should an applicant wish to have a licence decision reviewed, the applicant may request the Minister for Health to review the decision. The request must be in writing and be given to the Minister within 28 days of the making of the licence decision.

If a request for review is lodged, the Minister must reconsider the licence decision and confirm, vary or set aside the decision.

The Minister is taken to have confirmed the licence decision if the Minister does not give written notice within 60 days of the request.

Review by the Administrative Review Tribunal (ART)

An application may be made to the ART for review of a decision of the Minister. 
 

 

 

 

Regulatory Guide - Preparation of the safety analysis report for non-reactor facilities (ARPANSA-GDE-1925)

A guide for applicants and licence holders on what ARPANSA expects to be considered in the preparation and maintenance of the safety analysis report for a non-reactor facility 

1. Introduction

1.1. Background

When a controlled person as defined in section 13 of Australian Radiation Protection and Nuclear Safety Act 1998 (the Act) [1] intends to undertake any of the following activities:

  • prepare a site for a controlled facility
  • construct a controlled facility
  • have possession or control of a controlled facility
  • operate a controlled facility
  • decommission, dispose of or abandon a controlled facility 
  • remediate a prescribed legacy site

they must submit a facility licence application to ARPANSA. Section 46 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations) [2] details what the application must contain. In particular, section 46(1)(e) requires a safety analysis report (SAR) to be provided for each activity described above.

The SAR is a document produced by the operator which details the site and facility, describes any hazards and risks associated with the facility, how the facility will be used and managed, and the controls that must be in place to mitigate the risks.

The SAR must cover technical, organisational and human factors in a systemic/holistic approach to safety. The SAR is usually a detailed top-level document that references all supporting evidence, for example, the risk assessments and the operators’ management system (plans and arrangements).

The primary user of the SAR is the operator who should use it as a reference document to manage safety throughout the life of the facility. The SAR is a ‘living’ document which, as operations evolve and operational knowledge is gained, is continuously reviewed and updated so that operational safety margins are known and managed accordingly. All changes to the SAR must be assessed against the change requirements of s63 and s64 of the Regulations.

The SAR is also important to the regulator. Assessors must critically examine and test the SAR to ensure that it demonstrates that the facility is safe and can be operated safely into the future. The assessor must ensure that the SAR informs the licensing basis for the facility on which a program of safety oversight and compliance monitoring will be established. This is achieved through the clear identification of performance standards for any aspects important for safety including the arrangements to ensure that the SAR is maintained and accurate.

The SAR describes all activities with safety significance in appropriate detail including any restrictions on inputs to and outputs from the facility. It should include the application of the safety principles and criteria in the design for the protection of workers, the public and the environment. The SAR should contain an analysis of the hazards associated with the operation of the facility and should demonstrate compliance with the regulatory requirements. It should also contain analyses of accidents and of the safety features incorporated in the design for preventing accidents or minimising the likelihood of their occurrence and for mitigating their consequences in accordance with the concept of defence in depth.

1.2. Objective

This document provides guidance for an applicant, a licence holder and/or a responsible person1[3], technical support organisations, and other interested parties on preparing safety analysis at each stage of the facility life. It aims to assist in ensuring that the safety analysis of non-reactor facilities is prepared in accordance with international best practice. This document is also used for the regulatory assessment of a licence application for each stage of a controlled facility.
The safety analysis confirms that the design of a facility:

  • is capable of meeting the design and safety requirements and to derive or confirm operational limits and conditions that are consistent with the design and safety requirements
  • assists in establishing and validating accident management procedures and guidelines
  • assists in demonstrating that safety goals which may be established to limit the risks posed by the facility are met 
  • helps to demonstrate that the design of the facility reflects effective defence in depth and that the plant design and operation are robust and provide acceptable levels of safety

1.3. Scope

This regulatory document provides guidance for undertaking the safety analysis of non-reactor nuclear facilities and other controlled facilities including radioisotope and radiopharmaceuticals production facilities, radioactive waste management facilities, particle accelerators and research and development facilities. The document covers radiation risks and associated consequences arising from facilities.

For guidance on the safety analysis of research reactors, ARPANSA uses guidance published by the IAEA in Specific Safety Guide SSG-20 [4]. 

For guidance on the safety analysis for remediating a prescribed legacy site, ARPANSA uses guidance published by the IAEA [5]. 

For the guidance on safety analysis for abandoning a prescribed legacy site, ARPANSA uses guidance published by the IAEA [6]. 

1.4. General Expectations

Submissions to ARPANSA should be accurate and complete and be built from claims, arguments and evidence. A claim is a statement by the applicant about a property of an object or process. The evidence is an artefact that establishes fact to support the claim.  Arguments describe the relationship that links the evidence with the claims to demonstrate that they have been met.  

The regulatory assessor must assess any claims and arguments that lack supporting evidence with caution. Such claims and statements should carry less weight in the overall assessment. A good quality SAR also helps to demonstrate the applicant’s understanding of a facility and its operation and is therefore an indirect indication of the applicant’s capacity to comply with any licence issued (as required under section 53(f) of the Regulations.  

An example of a claims-arguments-evidence approach is provided in Appendix A of this guide.

2. Content of the safety analysis report

This section of the guide provides general guidance on the topics for a typical SAR for a non-reactor facility. ARPANSA does not stipulate a format or structure for a SAR. This should be determined by the applicant or licence holder to meet its organisation’s requirements. The section headings shown below may be suitable for different chapters of the SAR. The content of the SAR should be applied as far as practicable and in a graded approach commensurate with the degree of hazard associated with the conduct or dealing. Graded approach is defined by the IAEA as a process or method in which the stringency of the control measures and conditions to be applied is commensurate, to the extent practicable, with the likelihood and possible consequences of, and the level of risk associated with, a loss of control.

2.1. Introduction and facility description

  • An introduction of general information about the facility and any associated facilities.
  • Facility overview should typically include the purpose of the facility, facility configuration, and the processes to be performed therein. The safety objectives and design requirements should also be included.      
  • Facility description should include the facility and processes in support of hazard identification, hazard and accident analysis, and selection of hazard controls. The description of the facility will allow the reader to understand facility structures, operations and application. Graded information should be provided based on the hazard category and the complexity of the safety analyses.
  • Facility structure should include facility buildings and structures including construction details such as floor plans, equipment layout, construction materials, and dimensions relevant to hazard and accident analyses.
  • Process description should include details on basic process parameters including: (1) types and quantities of radioactive and other hazardous materials; (2) process equipment; (3) instrumentation and control systems and equipment; (4) basic flow diagrams; and (5) operations including major interfaces between structures, systems and components (SSC).

2.2. Site characteristics

The site description should describe the location of the site and of the facility on the overall site, identify facility boundaries, and locate nearby facilities that could affect the safety of operations or be affected by the facility. Information should be provided on external accident initiators both natural and man-made to support assumptions used in the hazard and accident analyses.

  • Information on the geological, seismological, hydrological and meteorological characteristics of the site and the vicinity in conjunction with present and projected population distributions, land use, site activities, and planning controls should be included. For low hazard facilities it is not necessary to discuss meteorological conditions, hydrological, geological, seismological characteristics, and offsite accident effects.

2.3. Safety structures, systems and components

  • Information should be provided on the structures, systems and components (SSCs) necessary to protect the public and workers and to provide major contributions to defence in depth. The section should also describe the attributes (functional requirements and performance criteria) required to support the safety functions identified in the hazard and accident analyses and to support subsequent derivation of safety requirements. In preparing information the Regulatory Guide: Construction of an item important for safety [7] should be consulted.
  • The design codes, standards and guides used for establishing the safety basis of the facility should be listed. 
  • The description of each such SSC should contain sufficient detail for describing its safety function and its relationship to the facility safety analysis taking into account the design basis and various modes of operation. 
  • The SSCs should be categorised based on the importance of the safety function(s) they provide, the consequences of failure to perform the safety function, and related factors.
  • Information on: component reliability, system interdependence, redundancy, diversity of fail-safe characteristics and physical separation of redundant system; evidence that the material used will withstand the postulated conditions; provisions for tests, inspections and surveillance, and effects of ageing on the operability of the SSC should be provided.

2.4. Hazard and accident analysis    

  • Detailed information should be provided on the evaluation of normal, abnormal, and accident conditions. The process used to systematically identify hazards, categorise the facility, and evaluate the potential internal, man-made external, and natural phenomena events that could trigger accidents should be described in this chapter. 
  • Postulated initiating events, including human induced events, which could affect safety should be identified and their effects, both individually and in credible combinations, should be evaluated. The list of internal and external hazards, including human induced hazards should be used to select initiating events for detailed analysis. Expert judgement, feedback from operating experience of similar facilities and deterministic assessment should be used for identifying postulated initiating events.
  • Certain events might be consequences of other events, such as a flood following an earthquake. An external hazard causing multiple simultaneous events on a site and major releases of hazardous chemicals and radioactive material from various source locations should be considered in the hazard analysis. This should include the provision of external services to the facility that may be impacted. Credible consequential effects should form part of the initiating event. The impact of multiple correlated events on a single facility and the impact of a single event on all facilities on the same site should be considered in the safety analysis.
  • For each hazard scenario, hazard evaluation should typically describe:
     
    • unmitigated hazard scenario and assumptions such as the initiating event, energy sources, qualitative or quantitative magnitude of radioactive or other hazardous material involved, release pathway(s), and initial conditions, if any
    • estimated likelihood of the unmitigated hazard scenario
    • estimated unmitigated consequences of the hazard scenario for the facility worker (qualitative or semi-quantitative), the workers of the co-located facilities (qualitative or semi-quantitative), and the public
    • available preventive and mitigating controls
       
  • Where a large number of scenarios are involved simple summary groupings and summaries in terms of hazards, energy sources, causes, preventive and mitigating features, unmitigated consequence estimates, and unmitigated frequency estimates may be presented in this section.
  • The accident analysis should include accident selection, design basis accident and design extension conditions. For each design basis accident or equivalent the consequences to personnel, the public and the environment should be evaluated.   
  • In analysing the design basis accidents each event scenario (or group of event scenarios), the safety functions and corresponding items important to safety and administrative controls that are used to implement the defence in depth should be identified.     
  • For multi-facility sites the potential interaction with or impact from accidents at other facilities on the same site should be considered in the analysis of the fourth and fifth levels of defence in depth.
  • Where appropriate the analysis of design basis external events should demonstrate that the design is adequately conservative so that margins are available to withstand external events more severe than those selected for the design basis.
  • The analysis of internal events should demonstrate whether the SSCs are able to perform their safety functions under the loads induced by normal operation and the anticipated operational occurrences and accident conditions that were taken into account explicitly in the design of the facility.

2.5. Operational limits and conditions

This chapter should provide and justify functional safety requirements derived from the functions of the SSCs and the accident analysis. This may include safety limits, safety systems settings, limiting conditions for operations, surveillance requirements and administrative requirements.

  • The safety limits2 of the process variables or parameters required for adequate control of the operation to protect the integrity of the physical system designed to guard against the uncontrolled release of radioactivity should be clearly described. These limits should reflect the capacity of the facility rather than its intended use or proposed production level. 
  • Safety system settings3 should be provided for those process variables and parameters having significant safety functions such that if not controlled could result in a safety limit being exceeded.  The analysis should demonstrate that the safety limits will not be exceeded.
  • Limiting conditions for safe operation should be clearly described demonstrating that there are acceptable margins between normal operating values and the safety system settings for items important to safety. 
  • The settings for limiting conditions for safe operation should avoid the undesirably frequent actuation of safety systems. Limiting conditions for safe operation should include limits on operating parameters, requirements relating to minimum operable equipment and minimal staffing levels, and interventions to be taken by operating personnel to avoid the need for actuation of safety systems.
  • Surveillance requirements describing the frequency and scope of periodic testing, calibration, or inspection activities to assure that necessary performance of systems and components is maintained and facility operations remain within safety limits, safety system settings and limiting conditions for safe operation.
  • The administrative and organisational requirements for operational procedures, staffing, training and retraining of personnel, review and audit procedures, maintenance, modifications, records and reports, and required actions following a violation of operational limits and conditions should be clearly described. 
  • The operational limits and conditions need to include administrative requirements concerning the organisational structure of the operating organisation and the responsibilities of key positions necessary for the safe operation of the facility.

2.6. Radiation protection

  • A description of protection objectives, criteria and principles, including application of the principle of optimisation of protection and safety and the radiation sources in the facility. The information should include the radiation protection objectives of the design and a description of the dose limitation system for workers and the public including requirements for the optimisation of protection. All potential sources of radiation due to operation of the facility should also be described.
  • Design features for radiation protection including radiation safety systems (e.g. shielding, ventilation) and appropriate equipment to ensure that radiation protection and contamination control are adequately provided for operational states of the facility should be described.
  • The operational radiation protection program describing the administrative controls, equipment, instrumentation and facilities and procedures for radiation protection should be included noting that a ‘radiation protection plan’ is required by subsection 46(1)(iii) of the Regulations as part of the plans and arrangements for managing the facility. Detailed guidance on preparing a ‘radiation protection plan’ is presented in ARPANSA’s Regulatory Guide: Plans and arrangements for managing safety [8].

2.7. Radioactive waste management

  • A description of the adequacy of measures for the safe management of all types of radioactive waste generated throughout the lifetime of the facility. These measures should be based on a waste management policy and strategy. This includes compliance with the applicable requirements for radioactive waste and effluent management. Descriptions of the facility design provisions, operating procedures and practices to minimise the generation of radioactive waste and effluents as well as the arrangements for managing the radioactive waste generated including segregation, monitoring, treatment, transport, storage and monitoring while in storage should also be included in this chapter. It is noted that a ‘radioactive waste management plan’ is required by subsection 46(1)(iv) of the Regulations as part of the plans and arrangements for managing the facility. Detailed guidance on preparing a ‘radioactive waste management plan’ is presented in ARPANSA’s Regulatory Guide: Plans and arrangements for managing safety.
  • The radioactive waste management system covering gaseous, liquid, and solid waste should be described in accordance with the description of SSCs as applicable. The solid, liquid, and gaseous waste streams and sources including estimated inventories should be summarised in this chapter.
  • Estimates of the quantity, volume, and characteristics of secondary radioactive waste resulting from radioactive waste pre-treatment or treatment in the facility. Possible disposal routes for the radioactive waste generated from the facility should be identified and presented in this section. Guidance for classifying radioactive waste with primary focus on long term safety after disposal is provided in the Guide for Classification of Radioactive Waste [9]. The classification scheme supports implementation of the safety requirements outlined in the Code for Disposal Facilities for Solid Radioactive Waste [10].

2.8. Decommissioning

  • A comprehensive baseline radiological characterisation of a site should be undertaken prior to a facility becoming operational as this will greatly assist the decommissioning and site remediation processes.
  • This chapter should describe the provisions and measures considered in the facility’s design, construction, commissioning and operation to facilitate decommissioning (e.g. modular construction to facilitate dismantling, operational practices to reduce generation of radioactive waste, operation and maintenance record keeping, control of modifications).
  • Information on conceptual plans for decommissioning should be presented to demonstrate that adequate measures have been taken in the design and operation of the facility. This includes an evaluation of vulnerabilities to a spectrum of events to minimise site or environmental contamination that would complicate decommissioning or limit the effectiveness of environmental restoration.
  • The provisions for managing the radioactive waste that will be generated during decommissioning of the facility should also be included in this chapter. Details of guidance on decommissioning are presented in the ARPANSA Regulatory Guide: Decommissioning of controlled facilities [11].
  • Design aspects such as SSCs which will facilitate decommissioning, and potential points of contamination which will facilitate decommissioning should also be included in this chapter.
  • The information on decommissioning should be adequate to demonstrate that an appropriate decommissioning plan has been prepared and will be maintained throughout the lifetime of the facility and that decommissioning can be accomplished safely and in such a way as to meet the defined end state.

2.9. Emergency planning and preparedness 

  • A description of the emergency planning and preparedness arrangements of the facility describing policies and procedures including but not limited to the prompt declaration of an emergency, timely notification, activation of emergency response, assessment of the situation and implementation of necessary protective actions, and coordination of response actions and communication with relevant authorities. These arrangements should be based on the emergency preparedness category of the facility as required in GSR Part 7 [12].
  • The emergency procedures should include the actions to be taken to mitigate the consequences of a nuclear or radiological emergency.
  • Emergency procedures should be based on the accidents analysed in the safety analysis as well as those additionally postulated for the purposes of emergency planning in accordance with the requirements of GSR Part 7.
  • Detailed guidance on preparing an ‘emergency plan’ is presented in ARPANSA’s Regulatory Guide: Plans and arrangements for managing safety [8].

2.10. Management System

  • This chapter should describe the planning, implementation and control of essential activities relating to the management system procedures to ensure that the specific requirements at each stage of the facility — such as regulatory requirements, design and construction criteria, and acceptance criteria — are correctly applied and fulfilled. In particular, the responsibilities and authorities of the personnel concerned under the management system should be specified.
  • The management system should consider four functional categories: management responsibility; resource management; process implementation; and measurement, assessment and improvement. The reporting hierarchy and lines of responsibility and authority should be such that they do not create conflicts between organisations and activities that could compromise safety during that conduct.    
  • The management system should include provisions to ensure that relevant aspects of each stage of the facility such as the facility design, changes to the design, operating procedures, organisational structure and safety assessment are appropriately addressed.
  • Activities including development, review, and approval of engineering calculations and documents, use of computer codes and their updates should be included in the management system.
  • The management system should include the plans and arrangements for managing safety and in particular how effective control is maintained.

Detailed guidance on preparing the management system is presented in ARPANSA’s Regulatory Guide: Plans and arrangements for managing safety [8]. ARPANSA expects the management system to be reflective of IAEA GSR Part 2: Leadership and Management for Safety [13].

Appendix A: An example of a claims-arguments-evidence approach to demonstrating the safety case 

Claim: 

The facility presents an acceptably low risk of radiation exposure to personnel.

Arguments:

  • The facility design has taken into account the potential for radiation exposure of personnel.
  • Area radiation monitors are installed to provide indication of a radiation levels and to alarm if pre-set values are exceeded.
  • Personnel receive training in radiation awareness, radiation protection, safety culture, task procedures and procedural use and adherence.

Foreword

This Regulatory Guide has been prepared to advise potential Commonwealth applicants, the public, and other stakeholders of the issues that will have to be addressed by an applicant when applying for a licence under the ARPANS Act to prepare a site for a controlled facility. It describes objectives for protection of human health and of the environment, drawing upon international best practice in relation to radiation protection and nuclear safety. I may decide to issue a licence authorising an applicant to prepare a site for a controlled facility only if the applicant demonstrates that the proposed facility will achieve the required level of radiation protection. The application should provide enough information to demonstrate that the facility can operate safely under all foreseeable circumstances. This Regulatory Guide is an update of the draft 1999 Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) Regulatory Guidance. It has been finalised after consideration of comments received during stakeholder consultation that occurred in the production of this Guide.

CEO of ARPANSA

August 2014.

1. Introduction

1.1 Purpose and Structure of this Regulatory Guide

This Regulatory Guide is directed to Commonwealth entities applying for a licence under the Australian Radiation Protection and Nuclear Safety (ARPANS) Act 1998 (Cwth 1998) to prepare a site for a controlled facility, and to other stakeholders including the public, to:

  • assist in understanding the overarching statutory considerations and how the application will be assessed by the regulatory body
  • assist in understanding the requirements for the content of an application and to address the question “what is required?” in the application process
  • provide guidance based on national and international best practice for meeting the requirements and attaining high levels of safety and security.

The relevant Australian regulatory and safety standards framework is summarised in this introductory chapter (Part 1).

Parts 2 and 3 of the Regulatory Guide, ‘Requirements for Siting a Controlled Facility’, present:

  • the requirements from Australian standards and codes of practice that are mandated in legislation
  • additional guiding principles based on international best practice that establish the expectations of the CEO of ARPANSA for the protection of people and the environment.

Parts 4 and 5, ‘Technical Aspects of Site Selection’, provide guidance from international best practice for consideration by the applicant in meeting the relevant requirements. Some guidance on the system for protection of human health and the environment is presented in Annex A1. This Regulatory Guide replaces the draft Regulatory Guide RG-4 Criteria for the Siting of Controlled Facilities (ARPANSA 1999).

1.2 Scope

This Regulatory Guide draws together the essentials (requirements) that are set out in the ARPANS Act, Regulations and relevant national codes, and presents advice (guidance) to inform potential applicants seeking regulatory approval to site a controlled facility. The Guide, in setting out international best practice and the requirements established in legislation, does not set any new requirements.

The guidance presented here is generally applicable to the siting of all controlled facilities in Australia. Controlled facilities are defined in Section 13 of the ARPANS Act as:

(a) a nuclear installation; or

(b) a prescribed radiation facility.

A nuclear installation defined in Section 13 means any of the following:

(a) a nuclear reactor for research or production of nuclear materials for industrial or medical use (including critical and subcritical assemblies)

(b) a plant for preparing or storing fuel for use in a nuclear reactor as described in paragraph (a)

(c) a nuclear waste storage or disposal facility with an activity that is greater than the activity level prescribed by regulations

(d) a facility for production of radioisotopes with an activity that is greater than then activity level prescribed by regulations made for the purposes of this section.

A prescribed radiation facility is defined in Regulation 6 of the Australian Radiation Protection and Nuclear Safety Regulations 1999 (ARPANS Regulations). The definition includes the following types of facilities:

(a) certain particle accelerators

(b) certain irradiators used to deliver very high doses of ionizing radiation to material

(c) facilities (other than nuclear installations) used for the production, processing, use, storage, management or disposal of certain sealed and unsealed sources.

The Regulatory Guide: Licensing of Radioactive Waste Storage and Disposal Facilities v2 (ARPANSA 2013a) should also be referred to for the siting of waste storage and disposal facilities, as this guide provides specific guidance on matters that may not be covered in detail here.

1.2.1 Requirements and Guidance

In this Regulatory Guide, a requirement is something that is established by the ARPANS Act or the ARPANS Regulations. Specific requirements are stated in relevant national codes referred to in this Guide. In this context, the word ‘must’ is used to indicate that the particular requirement is essential.

Under Section 32(3) of the ARPANS Act, the CEO of ARPANSA is required to take into account relevant international best practice in relation to radiation protection and nuclear safety in deciding whether to issue a facility licence. In International Atomic Energy Agency (IAEA) safety standards, the Safety Requirements, which flow from the Fundamental Safety Principles (IAEA 2006), provide international best practice requirements to be met to ensure the protection of people and the environment, both now and in the future. These requirements are expressed as ‘shall’ statements together with statements of associated conditions to be met. Experience and expertise from other countries and international organisations should also be considered when determining what constitutes international best practice. Guidance is practice-specific advice on best practice and on how to comply with the requirements. This advice is generally based on an international consensus on the measures recommended. In general, the guidance presented in this Regulatory Guide reflects national and international best practice to help users of this document to attain high levels of safety and security. The guidance is expressed as ‘should’ statements. The advice is not mandatory, and alternative means are acceptable so long as safety and security objectives are met.

1.3 Legislative and Regulatory Framework

The regulatory environment in the Commonwealth of Australia for radiation safety and security embraces the following principles:

  • the prime responsibility for safety must rest with the person or organisation responsible for facilities and activities that give rise to radiation risks. This is the first principle of the IAEA Fundamental Safety Principles (IAEA 2006), and of the new draft Australian Fundamentals: Protection Against Ionising Radiation (ARPANSA 2014a).
  • the regulator, ARPANSA, is entirely separate from the proponent and/or operator of a controlled facility
  • international best practice will inform regulatory decisions and guidance on how to achieve the required safety and security outcomes
  • consultation with stakeholders, including the public and relevant governments, will be an integral part of the regulatory and licensing processes. Stakeholders are regarded as an asset who will contribute knowledge to the process. The role of stakeholders and their interaction with the regulator will be to ensure the most informed decisions and best possible outcomes.
1.3.1 The ARPANS Act and Regulations

The Commonwealth legislation relevant to the regulation of radiation and nuclear activities undertaken by Commonwealth entities are:

  • Australian Radiation Protection and Nuclear Safety Act 1998 (Cwth 1998)
  • Australian Radiation Protection and Nuclear Safety Regulations 1999 (Cwth 1999a).

The object of the ARPANS Act is to protect the health and safety of people and to protect the environment from the harmful effects of radiation. An application to site a controlled facility must address all of the relevant matters specified in the ARPANS Act and Regulations as well as providing any additional relevant information requested by the CEO of ARPANSA.

1.3.2 Matters to be Considered by the CEO

Subsection 32(3) of the ARPANS Act states:

‘In deciding whether to issue a licence under subsection (1), the CEO must take into account the matters (if any) specified in the regulations, and must also take into account international best practice in relation to radiation protection and nuclear safety.’

Regulation 41 specifies the matters which the CEO must take into account when assessing a licence application. These include:

  • the content of any submissions made by members of the public about the application
  • whether the information establishes that the proposed conduct can be carried our without undue risk to the health and safety of people, and to the environment; • whether a net benefit from carrying out the conduct relating to the controlled facility has been demonstrated (which in the case of waste management facilities, may involve a progressive and systematic reduction of hazards)
  • whether the applicant has shown that the magnitude of individual doses, the number of people exposed, and the likelihood that exposure will happen, are as low as reasonably achievable, having regard to economic and social factors
  • whether the applicant has shown a capacity for complying with the ARPANS Regulations.

When taking this last point into account, the CEO may consider whether the applicant has sufficient resources (competence, funding, staff and other resources necessary to achieve the outcomes) available over the lifetime of the proposed facility.

Sub-regulation 40(2) of the ARPANS Regulations states that, as soon as practicable after receiving an application for a facility licence, the CEO must publish a notice in a daily newspaper circulating nationally, and in the Gazette, stating that the CEO intends to make a decision on the application. If the licence application relates to a nuclear installation, then the CEO must also include in the notice:

  • an invitation to people and bodies to make submissions about the application
  • a period for making submissions
  • procedures for making submissions.
1.3.3 CEO’s Guiding Principles

Regulation 39 and Part 1 of Schedule 3 to the ARPANS Regulations specify the information that the CEO of ARPANSA may require from applicants for a facility licence. ARPANSA’s application form for a facility licence requires the relevant information in Part 1 of Schedule 3 to the ARPANS Regulations to be provided. This may include information about other relevant matters. This additional information, based on international best practice, is presented in this Regulatory Guide as guiding principles. These guiding principles represent the expectations of the CEO in assessing the completeness of any licence applications submitted to ARPANSA. It is important to understand the distinction between a regulatory requirement and an expectation. Applicants cannot be made to ‘comply with’ international best practice until such time as it is legally applied to them through licence conditions imposed by the CEO. That does not happen until the licence is issued. Through this Regulatory Guide however, ARPANSA is indicating where more detail in an application will be expected by the CEO based on international best practice. Under the ARPANS Act, a licence that is issued by the CEO of ARPANSA is subject to conditions in Section 35 of the Act, conditions prescribed in the ARPANS Regulations (Part 4, Division 4), conditions imposed by the CEO at the time the licence is issued and any condition imposed by the CEO under subsection 36(2) after the licence is issued.

1.3.4 Relevant National Codes, Standards and Guides

Regulation 48 requires licence holders to comply with the following recommendations and codes of practice when dealing with controlled materials, apparatus and facilities, including disposal of controlled material and apparatus:

  • the Code of Practice for the Security of Radioactive Sources (ARPANSA 2007);
  • the Recommendations for Limiting Exposure to Ionizing Radiation and National Standard for Limiting Occupational Exposure to Ionizing Radiation (ARPANSA 2002);
  • the Code of Practice for the Safe Transport of Radioactive Material (ARPANSA 2008);
  • the Code of Practice for the Disposal of Radioactive Wastes by the User (NHMRC 1985)
  • the Code of Practice for the Near-Surface Disposal of Radioactive Waste in Australia (NHMRC 1992).

Other relevant Australian requirements and guidance are available in:

  • the National Directory for Radiation Protection (NDRP, ARPANSA 2011)
  • Holistic Safety Guidelines (ARPANSA 2012a).
1.3.5 Environmental Protection and Biodiversity Conservation Act (EPBC Act)

An application to prepare a site for a controlled facility could, under Sections 21 and 22 of the Environment Protection and Biodiversity Conservation (EPBC) Act 1999 (Cwth 1999b), constitute a ‘nuclear action’ and require approval from the Environment Minister, if the ‘nuclear action’ has, will have or is likely to have, a significant impact on the environment. Nuclear actions should be referred to the Environment Minister and may have to undergo an environmental assessment and approval process.

Applications for approval under the EPBC Act will generally precede a licence application under the ARPANS Act. The need for a referral under the EPBC Act and the timing for submitting a referral should be discussed with the Department of the Environment early in the planning process. More information on the approval process under the EPBC Act is provided on the Environment Department’s website: www.environment.gov.au/epbc/protect/nuclear.html.

1.4 Flow chart of siting process

Figure 1 provides an overview, albeit simplistic, of the siting process. It is important to note that the highest-ranked site may not be the most plausible site for various reasons. If a rigorous timeline is involved in the project delivery, then several well-ranked sites may be short-listed for simultaneous site characterisation to minimise potential delays, with the best being chosen through that process. More details are provided in the following sections.

 

Step 1: Selection of potential sites. Step 2: ranking of selected sites. Step 3: Characterisation of preferred site(s). Step 4: Suitability of preferred site. If not suitable remove site from further consideration and go back to step 3. If suitable...

Requirements for Siting a Controlled Facility

2. The Licensing Process

2.1 Staged Licensing Approach

The staged licensing process follows from Section 30 of the ARPANS Act. Part 1 of Schedule 3 of the ARPANS Regulations prescribes the information that the CEO may require from an applicant for each type of authorisation. The staged licensing approach is consistent with international best practice. The stages of the licensing process for a controlled facility may include:

  • licence application to prepare a site (including conceptual facility design)
  • licence application to construct
  • licence application to possess or control
  • licence application to operate
  • licence application to decommission, dispose of, or abandon (close) a facility.

It should be noted that whilst the overall process is staged, there is strong linkage between each individual licence application. The licence application for each stage needs to be forward looking and contain sufficient information on the safety and security aspects of subsequent stage(s), to allow for an informed decision to be made by the CEO. Under some circumstances, an applicant may choose to submit applications for more than one licence simultaneously. The application to prepare a site for a controlled facility is expected to include details of the conceptual design, as well as a preliminary safety case and other aspects as further detailed in this Regulatory Guide. The application should provide enough information to demonstrate that the facility can operate safely under all foreseeable circumstances. As the process proceeds through the various stages, the safety case and accompanying safety assessment will develop accordingly. The staged approach will allow for continuous improvement in design, operation and safety throughout the lifetime of the facility. ARPANSA recognises the importance of gaining community support during all phases of the licensing process. Experience has shown that sound technical assessments alone are generally insufficient to ensure successful implementation. As already stated above in Section 1.3, communication and consultation with stakeholders is crucially important in building trust and confidence in the regulatory process. Guidance on effective communication and consultation, and the role of the safety case in dialogue with the public and in building confidence in the safety of the facility, is presented below.

2.2 Content of the Application – Overview

Licence applicants need to complete an application form for either a prescribed radiation facility or nuclear installation, depending on the activity levels of the controlled material in the facility as calculated under the provisions in Regulations 7, 8 and 11 of the ARPANS Regulations. Application forms and general regulatory guidance for licence applications are available for download from the ARPANSA website: www.arpansa.gov.au/Regulation/guides.

Section 34 of the ARPANS Act requires an application for a licence to be in a form approved by the CEO and be accompanied by such fee as is prescribed by the regulations. Regulation 39 of the ARPANS Regulations specifies the information and documents that the CEO of ARPANSA may require to be provided by an applicant/proponent.

While the format of the application is a matter for the applicant, each of the elements needs to be addressed to meet the requirements of the ARPANS Act, the ARPANS Regulations and all relevant regulatory guidelines published by ARPANSA. A graded approach should be used when developing the application, such that the level of detail included is consistent with the magnitude of the possible radiation risks arising from the proposed facility. The application should be written so that the application and associated documents can be independently assessed. To this end, all sources of information need to be appropriately referenced.

In addition to the ARPANS Act and Regulations, the following guidance documents are available on the ARPANSA website for licence applicants:

  • Regulatory Assessment Principles for Controlled Facilities (ARPANSA 2001a);
  • Regulatory Assessment Criteria for the Design of New Controlled Facilities and Modifications to Existing Facilities (RB-STD-43-00 Rev 1, ARPANSA 2001b);
  • Regulatory Guide: Plans and Arrangements for Managing Safety (ARPANSA 2013b);
  • Regulatory Guide: Applying for a Facility Licence for a Nuclear Installation (ARPANSA 2012b); and
  • Regulatory Guide: Applying for a Facility Licence for a Prescribed Radiation Facility (ARPANSA 2012c).

The regulatory assessment principles detail how the issues of safety culture, safety analysis, and defence-in-depth should be addressed in a licence application. They are primarily written for ARPANSA assessors, but may also assist licence applicants or operators in the preparation of the safety analysis report (an element of the safety case) which accompanies the licence application for a controlled facility. The regulatory guide on plans and arrangements provides guidance on the information to provide for protection of human health and the environment when addressing Part 1 of Schedule 3 to the ARPANS Regulations.

These are:

  • effective control
  • safety management
  • radiation protection
  • radioactive waste management
  • security
  • emergency.

2.3 Licence to Prepare a Site for a Facility (Including Conceptual Design)

The application for a licence to prepare a site for a controlled facility must comprise, as a minimum, the general information referred to in items 1 to 4 of Part 1 of Schedule 3 to the ARPANS Regulations and the specific information referred to in items 5 to 7 of Part 1 of Schedule 3, which specify additional requirements to be met by an application seeking authorisation for preparing a site for a controlled facility. These additional requirements are:

  • a detailed site evaluation establishing the suitability of the site
  • information describing the characteristics of the site, including the extent to which the site may be affected by natural and man-made events
  • any environmental impact statement (EIS) requested or required by a government agency, and the outcome of the environmental assessment.

The wording of these additional requirements is taken from the current ARPANS Regulations. While applications for approval under the EPBC Act will generally precede a licence application under the ARPANS Act, it is acknowledged that the outcome of an EIS assessment may follow a siting licence application but would be expected prior to a decision being made on that licence. These requirements are in line with the IAEA Safety Requirements for site evaluation for nuclear installations.

The IAEA Safety Requirements document titled Site Evaluation for Nuclear Installations (IAEA 2003) states:

Proposed sites shall be adequately investigated with regard to all the site characteristics that could be significant to safety in external natural and human induced events.

The applicant is expected to supply, in addition to details on the site characteristics, information on:

  • the conceptual design for the facility, focusing on how the design impacts safety and security at and around the preferred site;
  • the transport system to and from the facility (modes of transport, transport routes, distances involved, current traffic/transport infrastructure conditions and usage and projected future traffic flows/usage for the life of the project and risk analysis thereof, and related safety and security considerations);
  • the beginnings of a decommissioning plan that will develop through the construction and operation phases of the facility. The IAEA Safety Requirements: Decommissioning of Facilities (IAEA 2014a) state that during siting, decommissioning is under ‘consideration’, and planning for decommissioning shall start during the design phase
  • the availability of resources over the lifetime of the proposed facility, including for decommissioning.

Some of these aspects (e.g. as regards facility design and decommissioning plan) are expected to develop as the project matures, and in their developed state must form part of the licence applications for future stages including the licence applications to construct or to operate the controlled facility.

3. Requirements and Guiding Principles

3.1 Demonstrating Radiation Protection

An application for a licence to site a controlled facility should contain enough information to demonstrate that there is a reasonable likelihood that the proposed facility:

  • can be sited, constructed, operated and closed safely
  • will meet all relevant legislative and regulatory requirements relating to radiation protection under all reasonably foreseeable circumstances.

It is recognised that some aspects related to this assessment may not be fully detailed at the siting stage; however, the assessment should consider reasonable values for materials that are likely to be handled at the site and any exposure scenarios that are likely to occur for this type of facility. Where site specific data are unavailable, data from similar sites and facilities could be used.

Additional information on the radiation protection principles and regulatory requirements that should be considered are provided in the national standard Recommendations for Limiting Exposure to Ionizing Radiation (1995) and National Standard for Limiting Occupational Exposure to Ionizing Radiation (2002) (ARPANSA 2002) and in Annex A1 of this guide.

3.2 Safety and the Safety Case

The requirements from international best practice to include a safety assessment and a developed safety case in an application for a licence to prepare a site for a controlled facility are implicit throughout the IAEA Safety Requirements.

The ARPANS Act and Regulations contain no specific requirement for the preparation of a safety case based around safety assessment principles for a controlled facility. However, based on international best practice requirements, a guiding principle of the CEO is that the applicant shall demonstrate that any proposed facility will meet the required level of protection by carrying out and presenting a safety case that draws upon the organisational and technical arrangements put in place, the characteristics of the site, the design of the facility, including any engineered safety barriers, and the arrangements for its construction and operation. Guidance for developing a safety case in compliance with this principle can be found in Section 4.2 of this Regulatory Guide.

3.3 Demographic Considerations

Based on international best practice, a guiding principle of the CEO is that an applicant for any licence covered by this Regulatory Guide shall, as part of the licence application, address the impact of the facility on the community in which the facility is, or is to be situated. All relevant current and future societal aspects shall be considered including transport routes within Australia and public concerns regarding local transport conditions.

3.4 Consultation

The expectation of the CEO is that the proponent shall include, in the application, an account of public consultation that has occurred, if any, including information on the format of the consultation, issues raised in submissions and responses to issues raised A guiding principle of the CEO is that the applicant for a facility licence for a nuclear installation will conduct appropriate stakeholder and public consultation, following a graded approach, in order to enable stakeholders to contribute knowledge to the siting and design processes. This is in addition to the requirement under Regulation 40 for public consultation by the CEO.

3.4.1 Summary of Application in Plain and Non-Technical Language

A guiding principle of the CEO is that the proponent shall provide a summary of the licence application and the supporting safety case, in plain and non-technical language, in order to facilitate stakeholder interaction in the review by the regulator of the licence application. The summary shall provide enough information and be presented in a format suitable for all stakeholders to understand the scope and content of the application, facilitate communication between all interested parties and promote understanding of the impact of the facility among all stakeholders. This plain-language summary may take the form of an executive summary of the safety case. Consideration shall be given to ensure that those who do not use English as their first language are included in the consultation process. Where Aboriginal people are involved as stakeholders, the expectation of the CEO is that such information shall be provided in a culturally appropriate manner.

3.5 Quality Assurance

In keeping with the IAEA Safety Requirements, a guiding principle of the CEO is that an application for a licence to prepare a site for a controlled facility shall include relevant aspects of a quality assurance programme, consistent with the stage of the project. A comprehensive quality assurance programme shall be applied to all safety-related activities, structures, systems and components of the controlled facility. This includes all related activities, from planning through siting, design, construction, operation, the various steps in the safety assessment process, long-term recordkeeping and decommissioning.

3.6 Provision of Adequate Funding

The IAEA states in the General Safety Requirements: Governmental, Legal and Regulatory Framework for Safety (GSR Part 1, IAEA 2010a) that:

The regulatory process shall provide a high degree of confidence… [that] authorized parties have the human, organizational, financial and technical capabilities to operate facilities safely or to conduct activities safely under all circumstances until their release from regulatory control.

A guiding principle of the CEO, based on international best practice, is that a licence application to prepare a site for a controlled facility shall include evidence of the provision of adequate financial resources over the lifetime of the controlled facility.

3.7 Security

An application for a licence to prepare a site for a controlled facility must address all relevant security issues as required under the Code of Practice for the Security of Radioactive Sources (RPS 11, ARPANSA 2007).

If nuclear material is involved in the facility, then progressively through the licencing process, beginning with concept design, the security systems and infrastructure protecting the nuclear material will need to comply with the requirements of the Convention on the Physical Protection of Nuclear Material (IAEA 1979) and the IAEA guidance document Nuclear Security Recommendations on Physical Protection of Nuclear Material and Nuclear Facilities (IAEA 2011a). This is managed through permits issued under s13 of the Nuclear Non-Proliferation (Safeguards) Act 1987 (Cwth 1987), administered by the Australian Safeguards and NonProliferation Office (ASNO). Nuclear security requirements vary considerably depending on the types and quantities of nuclear material and in many cases will be met by security measures put in place for compliance with RPS 11 without further modification.

3.8 Safety and Security Culture

Based on international best practice, a guiding principle of the CEO is that an applicant for a licence to site a controlled facility covered by this Regulatory Guide shall, as part of the licence application, provide information upon which an assessment can be made of the adequacy of the safety and security culture of the applicant organisation. The required information shall demonstrate the commitment of senior management within the operator to safety and security, and the establishment and maintenance of an appropriate culture within the facility to be licensed. ARPANSA’s expectations and advice are presented in the ARPANSA document Holistic Safety Guidelines (ARPANSA 2012a). Some details of how holistic safety will be implemented by ARPANSA are available on the ARPANSA website: http://www.arpansa.gov.au/Regulation/Holistic/index.

Any proposed change in the operator over the lifetime of the facility would be subject to similar scrutiny by the regulator.

The IAEA General Safety Requirements: Governmental, Legal and Regulatory Framework for Safety (GSR Part 1, IAEA 2010a) state the following:

Requirement 1 dealing with National Policy - “In the national policy and strategy, account shall be taken of the following: ... The promotion of leadership and management for safety, including safety culture.”

Requirement 29 dealing with Inspections - “In conducting inspections, the regulatory body shall consider a number of aspects, including: ... safety culture.”

3.9 Emergency and Remediation Preparedness

Principle 8 of the IAEA Fundamental Safety Principles (IAEA 2006) states that:

All practical efforts must be made to prevent and mitigate nuclear or radiation accidents.

The purpose of the information presented in this Regulatory Guide is to assist in selecting a site that will minimise the likelihood of any radiation accident associated with a controlled facility in Australia. However, history has clearly demonstrated that nuclear and radiation accidents that affect public and environmental health do occur.

Schedule 3 of the ARPANS Regulations states that an emergency plan for the controlled facility is required as part of the licence application to site a controlled facility. Information that may be useful in preparing this plan is available in Intervention in Emergency Situations Involving Radiation Exposure (ARPANSA 2004), and Regulatory Guide: Plans and Arrangements for Managing Safety (ARPANSA 2013b).

A guiding principle of the CEO based on international best practice (Larsson 2013) is that an application for a licence to site a controlled facility shall, as part of the licence application, provide information on how the chosen site meets criteria for remediation preparedness. The licence application to site a controlled facility shall include consideration of how the site characteristics may impact emergency and accident-recovery preparedness. Demonstration of adequate preparedness to remediate the effects of any environmental contamination arising from a radiation accident, including in the transport of radioactive materials, shall include information on the following:

  • division of responsibilities in accident recovery, including the role of stakeholders
  • approaches to defining targets and end states
  • potential methods and technology available for environmental remediation.

The purpose of such remediation preparedness, as well as helping to build trust and provide assurance for relevant stakeholders, is the recognition within the international radiation safety community, based on lessons learned from past major nuclear accidents, that it is too late to begin planning for accident recovery after an accident has occurred.

3.10 Identification of Representative Individuals of the Public

The International Commission on Radiological Protection (ICRP), in their Publication 101a Assessing Dose of the Representative Person for the Purpose of the Radiation Protection of the Public (ICRP 2006a) states that:

Dose to the public cannot be measured directly and, in some cases, it cannot be measured at all. Therefore, for the purpose of protection of the public, it is necessary to characterise an individual, either hypothetical or specific, whose dose can be used for determining compliance with the relevant dose constraint. This individual is defined as the ‘representative person’. The Commission’s goal of protection of the public is achieved if the relevant dose constraint for this individual for a single source is met and radiological protection is optimised. In accordance with the ICRP recommendations (ICRP 2006a), the CEO has determined as a guiding principle that the goal of protection of the public is achieved if the relevant dose constraint for the appropriately characterised representative individual is met and radiological protection is optimised.

3.11 Protection of the (Natural) Environment

In order to demonstrate that the proposed conduct can be carried out without undue risk to the health and safety of the environment, a guiding principle of the CEO is that the applicant shall undertake a screening assessment of doses to wildlife (i.e. animals and plants living within their natural environment) in the vicinity of the controlled facility by use of one of the internationally accepted screening tools. If a screening assessment indicates that exposures to relevant wildlife in the natural environment are likely to be higher than the screening dose rate (defined within the range 5 to 10 μGy per hour, depending on the conservatism demonstrated and species affected), more detailed assessments of potential environmental impact shall be undertaken.

Technical Aspects of Site Selection

4. General Guidance

General guidance applicable to the siting of controlled facilities is presented in this Section.

The ARPANS Act requires that, in deciding whether to issue a licence, the CEO must take into account international best practice in relation to radiation protection and nuclear safety. The CEO therefore expects an applicant for a licence to have regard to and apply international best practice. The previous sections describe the sources of international best practice for radiation protection and nuclear safety that predicate the CEO’s requirements and guiding principles. The sections below provide further guidance on the use of international best practice in framing an application for a licence to prepare a site for a controlled facility.

It is envisaged that an application will be based on:

  • international best practice in radiation protection and nuclear safety;
  • the results of available research; and
  • studies and data specific to the facility as appropriate.

Any and all unknown variables or assumptions made in the application should be clearly stated and discussed. The extent to which the limitations, if any, of available information may influence the conclusions of the application should be discussed.

ARPANSA recognises that there may be a need to make use of material that is considered to be of a confidential nature, for instance information of a commercial nature or on security grounds. The applicant may request that such information not be included in any publicly available document. ARPANSA would generally take the view that, subject to national security considerations, all relevant information would be available to the state/territory government where the facility is located.

4.1 Guidance on the use of the Graded Approach

The amount of detail provided in an application to site a controlled facility should be determined using a graded approach. This means that the level of detail and resources used should be proportional to the assessed level of risk (safety and security). When assessing the level of risk posed by the proposed facility, the applicant should consider:

  • the hazards and complexities of the work that will take place at the facility
  • the types of materials that will be used or stored at the facility
  • the particular characteristics of the planned facility and proposed site
  • potential impacts to workers, the public and the environment
  • any other relevant factors.

The application should provide enough information to demonstrate that the facility can operate safely under all reasonably foreseeable circumstances. If the possible risks to human and environmental health are low, the application may be less detailed than for a facility with higher risks.

If the EPBC Act is triggered, the siting licence application is likely to contain a similar level of detail to the Environmental Impact Statement required by the EPBC Act. The EPBC Act will have required a comparative assessment of the zero option (i.e. status quo – continue practices as now). This comparison process should be extended to the radiological safety and security aspects in the licence application.

Additional information on the graded approach can be found in the IAEA Safety Glossary (IAEA 2007).

4.2 Relevant International Standards

During the past decades, the IAEA has led the development of an international regime on nuclear and radiation safety. This involves three key elements: legally binding international treaties; globally agreed international safety standards; and provisions for facilitating the application of those standards.

A prime objective of the IAEA is to foster internationally harmonised approaches to radiation and nuclear safety, and to promote international best practice. A principal mechanism for achieving this harmonisation has been the establishment of internationally agreed safety standards and the promotion of their global application.

4.2.1 IAEA Safety Fundamentals

The hierarchy of IAEA Safety Standards involves three levels, with the IAEA Safety Fundamentals at the top. The document Fundamental Safety Principles (IAEA 2006) sets out the fundamental safety objective (to protect people and the environment from harmful effects of ionising radiation) and ten associated safety principles.

4.2.2 IAEA Safety Requirements

Beneath the Safety Fundamentals are the Safety Requirements, comprising seven General Safety Requirements (GSRs) and other Specific Safety Requirements. This integrated set of Safety Requirements establishes the international consensus of standards that is required to be met to ensure the protection of people and the environment, both now and in the future, governed by the objective and principles of the Safety Fundamentals.

An application for a licence to prepare a site for a controlled facility should address all relevant requirements from the GSRs and from the IAEA Nuclear Safety Requirements document Site Evaluation for Nuclear Installations (NS-R-3, IAEA 2003).

NS-R-3 establishes the requirements for site evaluation for a nuclear installation. Its purpose is to establish criteria to ensure that site related phenomena and characteristics are adequately taken into account, that emergency plans can be implemented over the lifetime of the facility, and that site-related hazards are defined.

The siting process for a nuclear installation generally consists of an investigation of a large region to select one or more candidate sites (site survey), followed by a detailed evaluation of those candidate sites. NS-R-3 is primarily concerned with the latter stage. It encompasses site related factors, and site-installation interaction factors, that relate to operating and accident conditions, including those that could lead to emergency measures. NS-R-3 is concerned with the evaluation of those site related factors important for ensuring that the site–installation combination does not constitute an unacceptable risk to individuals, the population or the environment over the lifetime of the installation.

The site evaluation for a nuclear installation covers the selection, assessment, pre-operational and operational stages. The requirements established in NS-R-3 do not apply to the site selection stage, for which a different series of criteria may be used, including criteria that have little direct relevance to safety.

4.2.3 IAEA Safety Guides

Beneath the Safety Requirements is a suite of Safety Guides which are based on an international consensus and provide assistance on how to comply with the Safety Requirements. Many of these guides have been developed primarily for the siting of nuclear power plants; however, they also contain information highly relevant to the siting of other facilities. Those that have particular relevance to siting are listed here:

  • Draft Specific Safety Guide DS433: Site Survey and Site Selection for Nuclear Installations (IAEA 2013a).
  • Safety Guide: External Human Induced Events in Site Evaluation for Nuclear Power Plants (IAEA 2002a).
  • Safety Guide: Dispersion of Radioactive Material in Air and Water and Consideration of Population Distribution in Site Evaluation for Nuclear Power Plants (IAEA 2002b).
  • Safety Guide: Geotechnical Aspects of Site Evaluation and Foundations for Nuclear Power Plants (IAEA 2004).
  • Safety Guide: Seismic Hazards in Site Evaluation for Nuclear Installations (IAEA 2010b).
  • Safety Guide: Meteorological and Hydrological Hazards in Site Evaluation for Nuclear Installations (IAEA 2011b).
  • Safety Guide: Volcanic Hazards in Site Evaluation for Nuclear Installations (IAEA 2012a).

The Nuclear Safety Requirements standard Site Evaluation for Nuclear Installations (IAEA 2003) does not cover the initial stage of the siting process, i.e. the site survey, when studies and investigations at regional scale are performed to identify potential sites from which candidate sites are chosen. This is covered in the new draft Safety Guide DS433: Site Survey and Site Selection for Nuclear Installations (IAEA 2013a)

The objective of DS433 is to provide guidance on the siting of a nuclear installation, for meeting the safety objectives of the IAEA Safety Fundamentals and complying with the Safety Requirements NS-R-3. Recommendations on criteria and approaches are provided in DS433 in order to identify suitable sites for nuclear installations complying with established safety requirements. The Safety Guide also has the objective of providing guidance on establishing a logical process for siting and establishing a suite of preferred candidate sites any of which could be selected for the construction and operation of a nuclear installation.

Safety Guide DS433 does not provide guidance on the final evaluation or characterisation of a site nor establish an assessment of the site hazard for use in the design evaluation for licensing purpose.

As the site survey and selection process does not require a licence from the regulatory body, the Safety Guide DS433 also has an informative role to the regulatory authority. If it is concluded during detailed assessment that no engineering solutions exist to design protective measures against those external hazards that challenge the safety of the nuclear installation, or there are no adequate measures to protect the peoples against unacceptable radiological risk, the site is not suitable and is not licensable. The siting process is intended to reduce such a late unfavourable conclusion from a safety point of view. The radiological safety of selected sites will be confirmed during the detailed site assessment stage.

DS433 explicitly addresses the safety aspects of the siting process of nuclear installations. It is recognized that there are other aspects that play an important role in the siting process, such as security, technology, economics, land use planning, cooling water availability, non-radiological environmental impact, and socio-economic aspects including public opinion.

As the siting process progresses, more and more sites will be screened out until only a few sites remain and the importance of safety aspects will become more pronounced.

The separation between the investigation processes of site survey and site evaluation may not be very distinct and will depend on the methodology used. There is a transition between these two stages of work and DS433 addresses the process that eventually terminates with the selection of site(s) for one or more nuclear installations.

As well as considering the siting of nuclear installations at new sites, DS433 provides recommendations regarding the collocation of new installations at existing sites.

4.3 The Safety Case

Systematic and internationally recognised approaches have been developed for assessing the safety of radiation and nuclear facilities. These involve developing a safety case for a specific facility. IAEA standards describe the safety case as an integration of arguments and evidence that describe, quantify and substantiate the safety, and the level of confidence in the safety, of the facility

A safety case submitted to ARPANSA as part of a siting licence application for a controlled facility should include the following elements as appropriate:

  • a safety assessment;
  • provision for periodic safety reviews and ongoing review and update as necessary of the safety assessment;
  • stakeholder involvement;
  • demonstration of the competence and adequate resources of the proponent;
  • a quality management system; and
  • methods for mitigating the consequences of an event or accident.

The safety case and supporting safety assessment provide the basis for demonstration of safety and for licensing, and should evolve with the development of the facility. The safety case should assist and guide decisions on siting as well as design and operations. The safety case will also be the main basis on which dialogue with interested parties will be conducted and on which confidence in the safety of the facility will be developed.

4.3.1 Safety Assessment

Safety assessment is the systematic assessment of all aspects of a practice that are relevant to protection and safety. The safety assessment should be started during the siting and conceptual design phase and be updated as necessary over the lifetime of the facility in order to account for possible changes in site characteristics, modifications to design or operation, new technical developments and regulatory standards.

The primary purpose of the safety assessment is to determine whether an adequate level of safety is being achieved for a facility or activity. Safety assessment provides reasonable assurance that the facility complies with all applicable regulatory requirements.

As stated in the IAEA General Safety Requirements: Safety Assessment for Facilities and Activities (IAEA 2009):

Safety assessments are to be undertaken as a means of evaluating compliance with safety requirements (and thereby the application of the fundamental safety principles) for all facilities and activities and to determine the measures that need to be taken to ensure safety. The safety assessments are to be carried out and documented by the organization responsible for operating the facility or conducting the activity, are to be independently verified and are to be submitted to the regulatory body as part of the licensing or authorization process.

IAEA (2009) lists 24 requirements for performing the safety assessment and all that are relevant will be considered in the assessment of any licence application. Particular attention is drawn to Requirement 1: Graded Approach to Safety Assessment;

A graded approach shall be used in determining the scope and level of detail of the safety assessment carried out in a particular State for any particular facility or activity, consistent with the magnitude of the possible radiation risks arising from the facility or activity.

It is expected that the safety assessment will become more detailed and based on the developed design and actual constructed facility as the project proceeds through the application stages.

The application should contain or make reference to sufficient information from any documentation or studies undertaken to enable the safety case to be understood by ARPANSA assessors and members of the public from the application alone.The application should provide the necessary information to enable interested stakeholders to understand the safety case and supporting safety assessment relating to the choice of the site and the proposed development of the controlled facility, having regard to international best practice in relation to radiation protection and nuclear safety.

4.4 The Representative Individual

For the purpose of radiation protection of the public, a representative person is an individual, either hypothetical or specific, who is characterised to be representative of the more highly exposed individuals in the population. It is considered that protection of the public is achieved when the dose to the representative person is less than the dose constraint, and when radiation protection is optimised.

When considering dose to the representative person, the ICRP (2006) recommend that the assessment should:

  • account for all relevant exposure pathways
  • consider the spatial distribution of radionuclides to ensure that the most exposed population is included
  • base habit data on the exposed population, and ensure that these data are reasonable, sustainable and homogenous
  • apply dose coefficients according to specific age categories.

Additional guidance on the use of the ‘representative individual’ in assessing doses to the public is available in the ICRP Publication 101a Assessing Dose of the Representative Person for the Purpose of the Radiation Protection of the Public (ICRP 2006a).

4.5 Public and Stakeholder Consultation

If the application is to site a nuclear installation, the public and relevant governments will be invited to comment and make submissions on the application (as per Regulation 40 of the ARPANS Regulations). The licence application will be the principal source of information on the facility from which interested individuals and groups may gain an understanding of what is proposed and the applicant’s arguments for its safety and security.

While ARPANSA is responsible for the conduct of the public submissions process under Regulation 40 of the ARPANS Regulations, the applicant should, separately, take appropriate steps to ensure that procedures are established and implemented to make information on safety aspects of the licence application available to members of the public.

The IAEA General Safety Requirements: Safety Assessment for Facilities and Activities (IAEA 2009), Requirement 22, requires that, “the processes by which the safety assessment is produced shall be planned, organized, applied, audited and reviewed.” This international bestpractice requirement includes the expectation that details of the safety case for the facility are communicated to the stakeholders:

Consideration is also to be given to ways in which results and insights from the safety assessment may best be communicated to a wide range of interested parties, including the designers, the operating organization, the regulatory body and other professionals. Communication of the results from the safety assessment to interested parties has to be commensurate with the possible radiation risks arising from the facility or activity and the complexity of the models and tools used.

In essence, in order to build confidence in the safety case, the applicant should demonstrate that there has been sufficient early and ongoing stakeholder involvement throughout the safety case development process.

4.6 Protection of the (Natural) Environment

The natural environment refers to all physical, chemical and biological conditions within which wild plants and animals normally live. Radiation protection of the environment is specifically concerned with wildlife living within its natural environment. Agricultural plants and domestic animals are considered under the protection of people.

The general intent of radiation protection of the natural environment is to protect ecosystems against radiation exposure that would have adverse consequences for populations of species (ICRP 2007).

The radiological environmental assessment for wildlife should be as simple as possible, but as complex as necessary. A graded approach should be used. The assessment should consider the likely exposure scenarios and pathways, including transfer of radionuclides to wildlife for internal dosimetry calculations. It should also include a discussion of scenarios and assumptions, limitations in the methodology or data used, and uncertainties in results. Protection should be subject to a screening dose rate for wildlife which depends on the conservatism demonstrated by the proponent in the screening assessment and species affected. The screening dose rate is defined in the range 5 to 10 µGy/h.

If the screening dose rate is exceeded, then a more complex assessment should be made. A more complex assessment could use, for example, less conservative assumptions or site specific data obtained from an environmental monitoring program. ARPANSA is currently preparing a safety guide titled Radiation Protection of the Environment (ARPANSA 2014b) to provide additional guidance on these types of assessment.

The IAEA is currently drafting the Safety Guide Radiation Protection of the Public and the Environment (IAEA 2014c) which will provide general guidance on the application of the IAEA Safety Fundamentals (IAEA 2006) and requirements of the revised International Basic Safety Standards (IAEA 2014b) in relation to protection of the public and the environment.

Another IAEA Safety Guide under development, A General Framework for Radiological Environmental Impact Assessment and Protection of the Public (IAEA 2014d), will assist the production of a Radiological Environmental Impact Analysis to assess the radiological impact on the environment of facilities and activities for which a radiation safety assessment is required for purposes of compliance with given acceptance criteria.

4.7 Security

Certain types of radioactive materials pose a security threat. Examples are radioactive sources of high activity, spent nuclear fuel and residues from reprocessing of nuclear fuel. A valid concern is that terrorist or criminal groups could gain access to such material and use it with harmful intent. Consequently, there has been a global trend towards increased control, accounting and security of such materials to prevent this happening.

To address these issues, the IAEA provides guidance and recommendations through the Nuclear Security Series and direct contacts with Member States on the security of radioactive sources. The recommendations from these documents and services are based on a set of Fundamental Security Principles and a methodology that considers the consequences of security-related events with respect to the State’s assessment of the threat. They enable the establishment of physical protection criteria that are balanced, provide security-in-depth, and whose implementation is graded by the severity of consequence.

The application of nuclear security principles to siting and the early stages of design of controlled facilities has the potential to increase security, decrease operational impact, lower operating costs and allow for greater integration with safety and safeguards systems. The types and quantities of radioactive material being held will largely influence the nature and extent of the consequences that may arise from security-related events.

It is often the case that the set of measures taken to establish a safety envelope or system for a facility or activity, as established and maintained through the implementation of relevant safety requirements, is affected by or “intersects” with the security envelope/system established through implementation of the security requirements. This intersection of measures taken to ensure facility or activity safety and security is commonly referred to as the safety-security interface. At this intersection, the measures taken to ensure safety or security can be mutually beneficial to maintaining the respective safety or security system. At the same time, some measures taken for maintaining the safety system may be detrimental to maintaining the security system, and vice versa. The importance for identifying these system interfaces is to ensure that the licence applicant recognises those that are not mutually supporting for safety and security, and the need for taking further measures to ensure that the respective safety and security system integrity is maintained. Less important, but worth identifying and taking advantage of, are those measures that are mutually beneficial.

The licence application should provide adequate information on security-related aspects of the site itself, including, but not limited to, site characteristics, proposed design of the facility and passive barriers, and proposed active security provisions such as alarms and on-site guards, etc. Where a proposed facility is to be collocated with new or existing facilities, any specific security issues arising from the collocation should be taken into account in the site evaluation for the proposed facility. For example, the siting of a new facility near an existing site which has security requirements that could be compromised may require special considerations during later phases.

5. Guidance on Site Selection and Characterisation

Selection and characterisation of potential sites for a controlled facility is a multi-step process as shown in Figure 2. The first step is to evaluate possible sites against a set of screening criteria. The sites that survive this process should then be evaluated and ranked against more rigorous selection criteria. The sites still under consideration will then undergo a detailed safety and impact assessment to determine whether the facility is likely to remain in compliance with legislative and regulatory requirements under all reasonably foreseeable circumstances. The conceptual design of the controlled facility should be taken into account during the site selection process in order to assess the potential radiological impact of the proposed facility.

Stakeholder involvement in the site selection process is extremely important, both in terms of general communication and also in terms of building confidence in the process.

While international best practice is to consider alternative sites, it is noted that in many cases for pragmatic reasons only one site is considered for full site evaluation

 

Figure 2: Flow chart showing the general steps involved in site selection and characterisation (adapted from IAEA 2013a).

5.1 Selection of potential sites

Initially, if there are multiple potential sites in the region of interest, these should be identified and assessed against the screening criteria.

5.1.1 Screening criteria

Screening criteria should be generic rather than site specific, and should be designed to eliminate sites that are obviously unsuitable from further consideration. The criteria should consider safety related aspects as well as any other aspects that would exclude a site from consideration.

Screening criteria should include:

  • site and regional characteristics that could obviously compromise safety
  • current and anticipated land use
  • cultural significance
  • economic significance
  • demographic considerations.

Screening criteria should be developed by the proponent, following international best practice and in consultation with stakeholders. Further information on the development of screening criteria can be found in the draft IAEA Safety Guide DS433 (IAEA 2013a).

5.2 Ranking of sites

Candidate sites should be compared and ranked in order of their attractiveness as the facility site. Selection criteria for ranking of sites should be more detailed than screening criteria and should be chosen to optimise the safety and efficiency of the proposed facility. Selection criteria may be site specific, particularly with respect to demography or environmental sensitivity issues, and will often include relevant social issues as well as technical/safety matters.

Criteria for ranking sites should be developed by the proponent in consultation with the regulator. Further guidance on the process of ranking potential sites is available in the draft IAEA Safety Guide DS433 (IAEA 2013a).

5.3 Evaluation of potential sites

The identification of the characteristics of the preferred site is an essential part of the site selection and evaluation process. There are several categories of site characteristics, including:

  • those that may affect the preparation of the site and the design of the proposed facility;
  • those that are needed to sustain the normal operation of the proposed facility;
  • those that provide input for the assessment of the radiological impact of a proposed controlled facility on the population and the environment; and
  • those that provide input for evaluating the feasibility of onsite and offsite emergency intervention and remediation preparedness following any accident.

Some characteristics (for example, availability of support services) may appear in more than one category.

The site characteristics (other than facility design) that could affect the assessment of the radiological impact of the proposed facility can be divided into three categories: features, events and processes. These are discussed in more detail in the following three sections.

Where relevant, the identified site characteristics should be assigned a frequency and severity, including uncertainties, from historical records. Where site specific frequency and severity data are unobtainable, data from other regions that are sufficiently relevant to the region of interest should be used. A graded approach should be used to determine the degree of detail required for the identification and description of site characteristics.

The information that should be considered for site characterisation is outlined in the following sections. This list is not exhaustive, and any additional information specific to the site under consideration should also be discussed.

5.3.1 Features

The features of a site that may affect the radiological impact of the proposed facility include geology, geomorphology, meteorology, and demography. Geology Geological information should include consideration of the following factors for both normal and extreme conditions (such as earthquakes and floods):

  • surface faulting
  • volcanic activity
  • landslides
  • permafrost
  • erosion processes
  • subsidence and collapse due to underground features
  • soil types and depths
  • rock types:
  • load bearing capacity
  • presence of fracturing
  • stability
  • liquefaction potential
  • groundwater levels and regimes.

Additional guidance can be found in the IAEA Safety Guide: Geotechnical Aspects of Site Evaluation and Foundations for Nuclear Power Plants (IAEA 2004).

Geomorphology

This includes geographical information about:

  • surface water features such as creeks and rivers
  • topography, such as mountains, valleys
  • any other features that could affect the diffusion or dispersion of airborne effluents or act as ultimate heat sinks.
Ecology

This includes information and details related to:

  • vegetation types and abundance
  • wildlife
  • threatened and endangered species.
Meteorology

Information on site-specific meteorological phenomena is essential for both site selection and facility design and for understanding the consequences of the releases of radioactive material at the site. Meteorological information should include data for both average and extreme conditions related to:

  • historical records of wind speed and direction, air temperature, precipitation (rain, snow, sleet), humidity, pressure, frontal systems
  • details of daily and seasonal and inter-annual variability
  • potential changes in climate and weather over the lifetime of the controlled facility.

Additional guidance can be found in the IAEA Safety Guide: Meteorological and Hydrological Hazards in Site Evaluation for Nuclear Installations (IAEA 2011b).

Demographics

This information should include:

  • present and projected population distributions in a form suitable for use in radiological assessments
  • details of transient, part-time or seasonal occupation, with best estimates of occupation time and numbers of occupants
  • details of present and projected land use (includes agriculture, livestock, dairy farming, wetlands, commercial, residential and recreation land and water use)
  • details of local diets, and locations and amounts of water used for drinking, industrial and recreational purposes
  • details of special needs groups (e.g. hospitals, aged care homes, prisons, child care facilities).

More detailed guidance can be found in the IAEA Safety Guide: Dispersion of Radioactive Material in Air and Water and Consideration of Population Distribution in Site Evaluation for Nuclear Power Plants (IAEA 2002b).

Services

The availability and vulnerability of services that are important to safety may influence the assessment of a site. Nearby services and transport routes may contribute to selecting the facility design and an understanding of the impact of a controlled facility on the population and the environment, and the feasibility of offsite emergency intervention.

Services of particular interest include:

  • electricity, gas, and water supplies, including back-up facilities;
  • provision of sewerage (which may be relevant to radioactive discharges);
  • communications;
  • transportation (road, rail, ship, air);
  • emergency services (fire, police, ambulance);
  • presence of facilities containing hazardous materials (e.g. chemical stores, munitions stores) or other hazardous facilities (e.g. chemical plant, fuel depot, power station) either on- or off-site; and
  • other nearby (collocated) on- or off-site facilities which may also require local services (interdependencies) and could contribute to or be impacted by emergency situations, particularly facilities and services which could potentially increase the risk to the public or the environment in emergency situations.
Radiological Baseline

Before any work commences on a proposed controlled facility, it is important to establish the radiological baseline of the site and surrounding areas, including information on the ambient radioactivity of the natural environment. This information should be used during operation of the facility to monitor performance of those site and facility features that help to isolate the facility from the surrounding environment. The information should also be used at the decommissioning and closure stages of the facility to assist in rehabilitation of the site to (approximately) its original state. Most of the (predictive) models used for assessment of post-closure impacts (including the effectiveness of decommissioning activities) on public health and the environment require a knowledge of the relevant source terms for possible releases of contaminated material to the environment and do not require information about the ambient background.

5.3.2 Events

The short-term events that may occur at a site that could affect the radiological impact of the proposed facility include:

  • severe weather phenomena such as thunderstorms, lightning, turbulence, cyclones, hail, storm surges, waterspouts, bushfires, drought and dust and sand storms;
  • floods on sites along streams, rivers and lakes caused by drainage, dam failure, ground water waves, or blockages and diversions in river systems ;
  • flooding resulting from extreme precipitation events, including those combined with snow and hail if appropriate;
  • tsunamis and related deposition, erosion and flooding;
  • seiches, storm surges and tidal variations for coastal regions;
  • earthquakes, fault displacement and other seismic events;
  • fires
  • inadvertent intrusion.

Information should be provided about historical occurrences, the likely future occurrences and potential impacts of these events.

Additional guidance can be found in the IAEA documents: Meteorological and Hydrological Hazards in Site Evaluation for Nuclear Installations (IAEA 2011b); Geotechnical Aspects of Site Evaluation and Foundations for Nuclear Power Plants (IAEA 2004); and Seismic Hazards in Site Evaluation for Nuclear Installations (IAEA 2010b).

5.3.3 Transfer Processes

In order to assess the impact of releases of radionuclides to the environment the on-going processes that can transfer radionuclides to (and through) the environment need to be understood. These processes can be both generic and site-specific.

In normal operating conditions, contaminated material from a facility can enter the environment as a result of processes such as erosion, or via discharge to the atmosphere, discharge to lakes and rivers, surface runoff following ingress of water, degradation of structures and containment barriers, leaching of contaminated material deposited on the ground, and via transport on vehicles and personnel leaving the site. These processes should also be considered when assessing the impact of unplanned releases of radioactive material to the environment.

Transport in the atmosphere

Detailed simulation of atmospheric transport processes requires information on wind direction, wind speed, atmospheric stability, diffusion, and wet and dry deposition. In addition, information considered should also include:

  • properties of the radioactive material released including total activity, chemical characteristics and physical properties
  • the type of release, including rate of release, time period of release, geometry and mechanics of discharge (and variation of these factors for different radionuclides).

In most situations the emphasis is on compliance, which means that the criteria against which an impact assessment is carried out are the annual dose limits set out in legislation, regulations or licence conditions. Information previously discussed on geomorphological and demographic features may also be required to complete these assessments.

Note that any airborne radioactive material that is deposited on the ground or on surface water could result in indirect contamination of surface water and/or groundwater.

More detailed guidance can be found in IAEA Safety Guide: Dispersion of Radioactive Material in Air and Water and Consideration of Population Distribution in Site Evaluation for Nuclear Power Plants (IAEA 2002b)).

Transport in the hydrosphere

The hydrosphere is a major pathway through which radioactive materials can be transported in both routine and emergency situations. This transport can occur via surface water (rivers, lakes, oceans and surface runoff), or in groundwater. Typically, radionuclides are transported rapidly in surface waters, and much more slowly in groundwater.

Surface water may become contaminated via direct contamination/discharge, or indirect contamination such as deposition of airborne contamination.

Radioactive materials may contaminate groundwater either directly or indirectly through either one of, or a combination of:

  • infiltration of contaminated surface water, resulting in leaching of radionuclides into groundwater
  • leakage of radioactive liquids to groundwater from a storage tank or reservoir
  • direct penetration into an aquifer.

The leaching process can be very slow and the time taken for contamination to reach measureable levels in groundwater depends strongly on the depth of the aquifer carrying the groundwater. This means that any impact assessment has to be carried out over an appropriate time period.

In all cases information about the source term for the discharge and the hydrological, physical, chemical and biological properties of the radioactive materials released should be considered in order to assess the impact of the discharge on people and the environment. The specific data necessary to assess these transport processes is different for surface water and for groundwater, and also varies depending on the water source (e.g. lakes, rivers, estuaries, seas and oceans, human made impoundments).

Any assessment of surface water and groundwater transport should also consider the features of the site detailed above, with specific consideration of:

  • agricultural, residential and recreational land use;
  • agricultural, residential, commercial and recreational water sources and water use;
  • land and water bodies supporting wildlife and livestock;
  • impacts on the food chain; and
  • detailed demographic information.

More detailed guidance can be found in the IAEA Safety Guide: Dispersion of Radioactive Material in Air and Water and Consideration of Population Distribution in Site Evaluation for Nuclear Power Plants (IAEA 2002b).

5.3.4 Impact assessment - routine operating conditions

The aim of any assessment of the impact of a proposed facility for routine operating conditions is to determine whether the proposed facility will comply with all relevant legislative and regulatory requirements. Where an impact assessment is required in the later stages of the site selection process, information will be required on the conceptual facility design, potential source terms (inventory), environmental transfer pathways and exposure scenarios. These have already been discussed in earlier sections. At the siting stage, detailed site-specific information may not be available, so default data (IAEA, 2010) should be used where necessary.

Examples of impact assessments are given in the reports from the Environmental Modelling for Radiation Safety (EMRAS) programme conducted by the IAEA (IAEA 2008; IAEA 2013b).

5.3.5 Emergency Preparedness
Defence in Depth

Defence in depth is an important component of the internationally accepted approach to optimising safety in the siting and design of controlled facilities. It uses multiple layers of protection in such a way that a loss of safety at any level is compensated by the protection provided by additional layers. Further details can be found in ARPANSA’s Regulatory Assessment Principles (ARPANSA 2001a).

Usually only a conceptual design is available for the proposed controlled facility at the siting stage. Therefore it is not possible to address in detail the potential for ‘beyond design basis’ accidents during consideration of the siting licence application, except to the extent that some elements of siting, such as natural barriers, are of importance.

A new concept in international best practice for enhancing nuclear safety is the consideration of ‘design extension conditions’ in the siting and design of a controlled facility (IAEA 2012b, Requirement 20). Design extension conditions are intended to improve safety by enhancing the controlled facility’s capabilities to withstand, without unacceptable radiological consequences, accidents that are either more severe than design basis accidents or that involve additional failures. The main objective in considering design extension conditions at the siting stage is to provide assurance that the site will not compromise the provision of defence in depth.

While design extension conditions are primarily addressed in the design phase of the controlled facility, some considerations during the siting licence application phase could include:

  • combinations of events and failures, where the results of engineering judgement, deterministic safety assessments and probabilistic safety assessments indicate that combinations of events could lead to accident conditions
  • physical separation and operational independence of safety systems
  • optimising avoidance of long term off-site contamination
  • improvement of the layout, particularly with respect to collocated facilities, to facilitate operation in accidental conditions.
Reference Accident

In the context of this document, which covers a wide range of potential sites and facilities, the concept of a reference accident is used to assess the radiological consequences of a hypothetical, short-term release of a very large quantity of contaminated material to the environment around the site being considered, against criteria intended to protect people and the environment. The radiological consequences of the reference accident should be determined using conservative assumptions.

The use of a reference accident allows the radiological suitability of a site for a proposed controlled facility to be assessed at the conceptual planning stage before the detailed design of the facility is known. The purpose of examining a reference accident at the siting phase is to determine whether there are any gross characteristics of the site that would render it unsuitable from a health and safety perspective, whatever levels of defence in depth are likely to be incorporated in the future design of the facility.

Since the actual design of the proposed facility is unknown at the site selection stage, the reference accident should consider only site-dependent factors (where appropriate to the site under consideration) such as:

  • discharge to the atmosphere under prevailing meteorological conditions
  • discharge to rivers, lakes and oceans
  • deposition on the ground surface and subsequent surface run-off and leaching into groundwater
  • the effect of natural features of the site on the consequences of such a release
  • the availability of resources for mitigating the consequences of such a release
  • the demographics and impact on exposed populations
  • the consequences of the release with respect to current and future land use
  • the ease of remediating the site and its surroundings once the emergency stage of the accident is over.

As the project proceeds through the respective licensing phases and the design and operational details of the facility are developed the nature of the reference accident may change.

Where a new controlled facility is planned for a site that already has one or more controlled facilities, the existing facilities should be accounted for when determining the radiological consequences of the reference accident. Further guidance regarding the selection of a reference accident and the criteria by which it is assessed can be found in ARPANSA’s Regulatory Assessment Principles (ARPANSA 2001a).

5.3.6 Preparedness for accident recovery

Site-related criteria that are relevant when considering remediation preparedness following any accident, both in terms of the impact on these criteria of any accident at the chosen site and their potential utility in remediation, include:

  • demographics, particularly the proximity of towns and cities
  • value of land – cultural and societal importance of land for agriculture, recreational activities and natural resources
  • social amenities such as schools and hospitals
  • availability of, and ease of access, to relevant services including water and power supplies and transport infrastructure
  • availability of and ease of access to technology to monitor and perform environmental remediation
  • systems of local governance
  • communal knowledge and acceptance of the controlled facility; means of communication for dissemination of advice amongst stakeholders
  • availability of natural and man-made structures to store and dispose of accident waste, including landfill sites; and • geographic parameters.

Annexes

A1. Requirements for Protection of Human Health and the Environment

The requirements for ensuring the protection of people (workers and the public) and the environment, now and in the future, from harmful effects of ionizing radiation are found in the national standard Recommendations for Limiting Exposure to Ionizing Radiation (1995) and National Standard for Limiting Occupational Exposure to Ionizing Radiation (republished 2002, which is prescribed in Regulation 48 of the ARPANS Regulations as a condition of licence) (RPS 1, ARPANSA 2002).

Regulation 41 requires that in deciding to issue a facility licence, the CEO must take into account, amongst other things, whether:

  • the information establishes that the proposed conduct can be carried out without undue risk to the health and safety of people, and to the environment
  • the applicant has shown that the magnitude of individual doses, the number of people exposed, and the likelihood that exposure will happen, are as low as reasonably achievable, having regard to economic and social factors.

A1.1 Radiation Protection Principles

The international framework for radiation protection rests on 3 principles, which have been confirmed in the most recent Recommendations of the ICRP in Publication 103 (ICRP 2007). These are justification, optimisation and dose limitation. All of these principles, fundamental to the system for control of exposure to radiation, must be met in accordance with the national standard (ARPANSA 2002). The international framework is continuously evolving and the national framework is continuously revised on that basis, as necessary and appropriate. Note that RPS 1 (ARPANSA 2002) is currently being revised to take into account ICRP Publication 103 (ICRP 2007) and IAEA GSR Part 3 (IAEA 2014b).

A1.1.1 Justification

Justification involves a demonstration that there is a net benefit from a practice which leads to exposure to radiation. As the benefits and detriments to be considered encompass all aspects of the proposed practice, the decision-making process covers far more than radiation protection alone and shall involve all appropriate governmental and societal decision-making agencies. Further details of this principle and guidance in meeting it are found in RPS 1 (ARPANSA 2002).

A1.1.2 Optimisation

Optimisation is employed to make the best use of resources in reducing radiation risks, once a practice has been justified. The broad aim is to ensure that the magnitude of individual doses, the number of people exposed, and the likelihood that potential exposures will actually occur shall all be kept as low as reasonably achievable, economic and social factors being taken into account (ALARA). Further details of this principle and guidance in meeting it are found in ARPANSA 2002 (Recommendations for Limiting Exposure to Ionizing Radiation (1995) and National Standard for Limiting Occupational Exposure to Ionizing Radiation (2002)) and in the ICRP Publication 101b (ICRP 2006b).

A1.1.3 Dose Limitation

Dose Limitation involves applying dose limits and constraints to optimise the total dose to any individual in planned exposure situations. Further details of this principle and guidance in meeting it are found in the following section regarding dose limits and dose constraints and in RPS 1 (ARPANSA 2002).

A1.2 Radiation Protection Criteria

A1.2.1 Public and Occupational Dose Limits and Dose Constraints

In siting and designing a facility, it must be taken into account that during the operational phase, the applicant must show that the design and operation of the facility provides for the protection of workers and members of the public such that:

  • radiation doses to the public and workers do not exceed the dose limits in Regulations 59 and 60 of the ARPANS Regulations;
  • facilities are designed and operated in such a way that radiation protection of workers and members of the public is optimised according to the principles described in Regulation 58 of the ARPANS Regulations
  • the consequences of any reasonably foreseeable fault or accident condition are such that radiation protection of workers and the public is optimised according to the principles described in Regulation 58 of the ARPANS Regulations.

During the operational phase the applicant must also propose a dose constraint for workers, below which protection will be optimised, in accordance with RPS 1 (ARPANSA 2002) and which is agreed to by the CEO. The expectation of the CEO is that the constraint would not exceed 5 mSv per annum.

A2. Definitions

Terms defined in the ARPANS Act and the ARPANS Regulations have the same meaning when the terms are used in this Regulatory Guide. All other definitions in this Guide are intended to be consistent with the definitions in the IAEA Safety Glossary (IAEA 2007).

Community

In this Regulatory Guide the term ‘community’ is used to define the level of spatial and social organisation at which the issue of demographics should be addressed by the license applicant in terms of ‘the impact of the facility on the community in which the facility is, or is to be situated’.

Defence in depth

‘Defence in depth’ is the application of more than one protective measure for a given safety objective, such that the objective is achieved even if one of the protective measures fails. This is often achieved through a hierarchical deployment of different levels of equipment and procedures.

The International Nuclear Safety Group (INSAG) defines five levels of defence in depth:

Level 1: Prevention of abnormal operation and failures.

Level 2: Control of abnormal operation and detection of failures.

Level 3: Control of accidents within the design basis.

Level 4: Control of severe plant conditions, including prevention of accident progression and mitigation of the consequences of severe accidents.

Level 5: Mitigation of radiological consequences of significant releases of radioactive material.

Design basis

The ‘design basis’ is the range of conditions and events that are explicitly taken into account in the design of a facility, such that the facility can withstand them without exceeding authorised limits by the planned operation of safety systems.

Design basis accident

An accident involving conditions that the facility has been designed to withstand while keeping damage to nuclear fuel and the release of radioactive material within authorised limits.

Beyond design basis accident

An accident involving conditions more severe than a design basis accident.

Design extension conditions

A set of conditions derived on the basis of engineering judgement, deterministic assessments and probabilistic assessments for the purpose of further improving the safety of the controlled facility by enhancing the facility’s capabilities to withstand, without unacceptable radiological consequences, accidents that are either more severe than design basis accidents or that involve additional failures. These design extension conditions shall be used to identify the additional accident scenarios to be addressed in the siting and design and to plan practicable provisions for the prevention of such accidents or mitigation of their consequences if they do occur.

Ecosystem

A complex and dynamic community of living (e.g. plants, animals, micro-organisms) and nonliving (e.g. water, air) components that interact as a functional unit.

Graded Approach

An application of safety requirements that is commensurate with the characteristics of the practice or source and with the magnitude and likelihood of the exposures.

Natural Environment

A collective term for all of the physical, chemical, and biological conditions within which wild plants and animals normally live (based on the Environment Protection and Biodiversity Conservation (EPBC) Act).

Nuclear Material

Plutonium except that with isotopic concentration exceeding 80% in plutonium-238; uranium233; uranium enriched in the isotope 235 or 233; uranium containing the mixture of isotopes as occurring in nature other than in the form of ore or ore residue; depleted uranium; thorium; any material containing one or more of the foregoing (IAEA Safety Glossary, IAEA 2007).

For the purposes of safeguards, the Commonwealth Nuclear Non-Proliferation (Safeguards) Act 1987 (Cwth 1987) defines nuclear material in accordance with the Australia-IAEA Comprehensive Safeguards Agreement.

The IAEA places safeguards on nuclear material, which is defined via Article XX of the IAEA Statue and the IAEA document INFCIRC/153 (1972):

"Nuclear material" means any source material or any special fissionable material as defined in Article XX of the Statute. The term source material shall not be interpreted as applying to ore or ore residue.

There are some exceptions as to what nuclear material is covered by this definition, and is therefore controlled under the Nuclear Non-Proliferation (Safeguards) Act 1987, but essentially this means uranium, thorium and plutonium in any quantity or form.

(Nuclear) Security

Security involves the prevention and detection of, and response to, theft, sabotage, unauthorised access, illegal transfer or other malicious acts involving nuclear material, other radioactive substances or their associated facilities.

Radioactive Material

For the purposes of this regulatory guide, radioactive material is material designated in national law or by a regulatory body as being subject to regulatory control because of its radioactivity.

Safety Analysis Report

The safety analysis report is an ARPANSA regulatory requirement that documents the formal safety analysis. In the context of this Regulatory Guide, the safety analysis report, together with the safety assessment, are considered to be appropriate elements of the safety case that demonstrates the safety of the storage or disposal facility. The extent and rigour of the safety analysis report is commensurate with the hazard categorisation of the facility. It is a living document that is updated as appropriate throughout the life of the facility (including the decommissioning stage) to reflect its current state.

Safety Assessment

Assessment of all aspects of a practice that are relevant to protection and safety; for an authorised facility, this includes siting, design and operation of the facility. This will normally include formalised risk assessment.

Safety Case

The ‘safety case’ is a collection of arguments and evidence in support of the safety of a facility or activity. This will normally include the findings of a safety assessment and a statement of confidence in these findings together with the safety analysis report that is an ARPANSA regulatory requirement.

The safety case may relate to a given stage of development (e.g. siting). In such cases, the safety case should acknowledge the existence of any unresolved issues and should provide guidance for work to resolve these issues in future development stages.

Stakeholder

Stakeholder means an interested party — whether a person or a group, etc. — with an interest or concern in ensuring the success of a venture. To ‘have a stake in’ something, figuratively, means to have something to gain or lose by, or to have an interest in, the turn of events. In this Regulatory Guide, the term does not include the major players in the licensing process (proponent, operator, regulator) but does include other national and regional governments and agencies.

Wildlife

‘Wildlife’ is defined as an animal or plant living within its natural environment.
