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. 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 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 | ARPANSA.

Submitting your application

Send completed application form and all supporting documentation to licenceadmin@arpansa.gov.au.

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, and if the correct application fee has been paid. 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.

Your application will then be forwarded 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 this. The officer will then prepare a regulatory assessment report to document the review. 

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 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. 

Under section 37 of the Act, a licence may be issued indefinitely or for a period specified in the licence. 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:

a) to refuse to grant a licence
b) to impose conditions on a licence
c) to suspend a licence
d) to cancel a licence
e) to amend a licence 
f) not to approve the surrender of a licence
g) to issue a licence for a particular period, rather than for a longer period or indefinitely
h) 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

  • 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.

These should be a comprehensive program of policies and procedures that demonstrate how safety and security will be ensured. The content of these plans and arrangements will vary depending on the hazard and complexity of the facility. 

There is no predetermined format for supplying this information. The applicant may either describe the plans and arrangements in the space provided 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 and provide the full title, version/edition, and approval date. 

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

If there are sources associated with the proposed facility, the applicant should identify the relevant codes and standards and describe how compliance with these documents will be achieved. This information may be included in Section E of the application. Codes and standards applicable to each kind of source can be found here.  

ARPANSA publishes information about international best practice (IBP) with links to various international standards that may be relevant to the proposed facility. Applicants should identify relevant IBP and describe how this will be implemented or taken into account.

Effective Control Arrangements

The applicant must demonstrate how he/she or the nominee will establish and maintain effective control over the facility. This should cover issues such as organisational arrangements, management systems and resources.

Safety Management Plan

The applicant must describe the administrative arrangements for managing the safety of the facility and any associated sources. This should cover issues 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 RPS F-1 Fundamentals for Protection Against Ionising Radiation, RPS C-1 Code for Radiation Protection in Planned Exposure Situations and RPS G-2 Guide for Radiation Protection in Existing 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.  

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. The applicant must provide information 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 conduct 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-3 Code for Disposal Facilities for Solid Radioactive Waste, CRPS C-6 Code for Disposal of Radioactive Waste by the User, RPS G-4 Guide for Classification of Radioactive Waste, and relevant IBP.

Security Plan

Arrangements for the security of the facility and any associated sources to prevent theft, damage or unauthorised access must be provided. These arrangements should demonstrate how the security of the facility and any associated sources will be maintained and how periodic inventory checks will be undertaken to confirm that all sources are secure and in their assigned location.

Refer to IAEA Nuclear Security Series NSS 14 Nuclear Security Recommendations on Radioactive Material and Associated Facilities and RPS 11 Code of Practice for Security of Radioactive Sources. Compliance with the latter code is mandatory for security enhanced sources. In particular, the need for an approved security plan should be noted.      

Emergency Plan

Emergency arrangements should be developed for all foreseeable emergencies such as dispersion of materials, over-exposure 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 level of detail should be commensurate with the hazard of the facility.

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

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

Environment Protection Plan

Arrangements should be developed for the protection of wildlife populations and ecosystems in parallel with radiation protection of people, consistent with international best practice. The arrangements should include identification of all potential exposure scenarios and pathways to the environment and affected biota with environmental radiological assessments of wildlife in their natural habitats based on the concept of reference organisms.

Refer to RPS G-1 Guide for Radiation Protection of the Environment.

Decommissioning Plan 

Arrangements should be developed that demonstrate adequate planning for decommissioning to protect workers, the public and the environment. While most decommissioning activities take place in the final phase of a facility’s lifecycle, decommissioning should be considered as early as possible. An initial decommissioning plan should be developed at the design stage and periodically updated throughout subsequent life stages. The objective is to develop a final plan to be submitted when applying for authorisation to decommission the facility. 

Refer to Regulatory Guide: Decommissioning of controlled facilities

Section F: Extra information

Applicants should provide additional information as shown in the table in section 46 of the Regulations specific to the type of authorisation sought.

Applicants should enter the information in the space provided or state clearly where this information can be found in the accompanying documentation. The full title, version/edition, and approval date should be provided for all referenced documents.

Applicants should complete the section(s) corresponding to the type of authorisation sought.  

Section G: Associated sources

Sources that are part of, used in connection with, produced by, incorporated in, stored in, or disposed of in, a facility do not need a separate source licence but must be authorised by the facility licence.  

Not all facilities have associated sources but where they do, this should be indicated in Section G of the application. A common type of source used in facilities is a calibration source.  For sealed sources, a copy of any source certificate should be provided.

Section H: Source details

The details of any sources associated with the facility must be recorded in a source inventory workbook (SIW). This is the form approved by the CEO for maintaining source records. The SIW template is available here. 

An explanation of terms and required information appears in the first worksheet of the SIW. If in doubt, contact ARPANSA for advice. The completed SIW should be submitted with the application. 

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

Subsections 32(3) and 33(3) of the Act require 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 licence. The CEO must also take into account the matters prescribed in section 53 of the Regulations.

Provide information on these matters in Section I of the application form.

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 international best practice. 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.  

Agencies such as the International Atomic Energy Agency (IAEA) or the Nuclear Energy Agency are useful resources, particularly in relation to safety assessment and stakeholder involvement. The IAEA standards and recommendations have been developed by consensus of member countries and represent the distillation of best practice of their cumulative radiation and nuclear safety experience. 

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 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 - Disposal of Sources (ARPANSA-GDE-1733)

 

Associated forms

Purpose of this guide

This regulatory guide sets out ARPANSA’s expectations for the disposal of: 

Explanation of terms

In this guide the generic meaning of ‘disposal’ is used. It includes the transfer of controlled apparatus and controlled material (collectively referred to as sources) to another ARPANSA licence holder or to a person/organisation outside of ARPANSA’s jurisdiction.

The term ‘source’ is used to collectively mean controlled apparatus and controlled material.   

A ’security enhanced source’ means a radioactive source or aggregation of sources assigned the Category 1, 2 or 3 when using the methodology set out in Schedule B of Code of Practice for the Security of Radioactive Sources (RPS 11).

Introduction

Section 65 of the Regulations provides 4 disposal options:

  1. The licence holder may dispose of controlled material or controlled apparatus with prior approval from the CEO
  2. The licence holder may without approval of the CEO transfer the controlled apparatus or controlled material to another licence holder under certain conditions
  3. The licence holder may without approval of the CEO dispose of the controlled apparatus by returning certain controlled apparatus to the supplier of the controlled apparatus in certain circumstances  
  4. The licence holder may without approval of the CEO dispose of certain controlled apparatus by rendering the controlled apparatus permanently inoperable as a controlled apparatus in certain circumstances.

Under option 2, prior approval is not required to transfer a source to another ARPANSA licence holder provided:

  • both entities hold an appropriate licence issued by the CEO of ARPANSA,
  • the apparatus does not contain a security enhanced source, and
  • the licence holder disposing of the apparatus tells the CEO about the transfer within 7 days.

A Source Transfer Notice must be submitted within 7 days of the transfer.

Where a licence holder routinely disposes of sources as part of routine operations the CEO of ARPANSA can make a special arrangement in the licence under subsection 65(5) of the Regulations so there is no need to seek prior approval to dispose of each source.  

Note: Temporary transfer of sources to a service agent for repair or maintenance is not a disposal as ownership is retained by the licence holder.  In such cases the licence holder must ensure that the service agent has appropriate training in radiation safety and training with respect to such activities (as required by all licences). 

Disposal of controlled apparatus

As defined in section 13 of the Act, controlled apparatus means any of the following:

  1. An apparatus that produces ionising radiation when energised or that would, if assembled or repaired, be capable of producing ionising radiation when energised
  2. An apparatus that produces ionising radiation because it contains radioactive material
  3. An apparatus prescribed by the regulations that produces harmful non-ionising radiation when energised.

Disposal of controlled apparatus often includes destruction or dismantling.

Disposal of controlled apparatus requires prior approval from the CEO of ARPANSA unless the licence makes other arrangements under subsection 65(5) of the Regulations OR the disposal meets the conditions described in paragraphs 65(1)(c) & (d) for certain controlled apparatus.  This allows Group 1 controlled apparatus to be returned to the supplier or rendered permanently inoperable without prior approval provided it does not contain controlled material.

To satisfy the CEO of ARPANSA of the ‘destruction’ of a controlled apparatus it must be rendered inoperable in such a way that only expert knowledge and the use of specialised components could potentially restore its function. 

In most cases, removal of a critical component(s) and severing the power cables will render the apparatus inoperable. For example: 

  • In the case of x-ray apparatus, eliminating the vacuum inside the x-ray tube by breaking the glass envelope and severing the high-tension cables will effectively destroy the apparatus.  
  • In the case of lasers removing the power supply, critical optical components or the amplifying medium will render the apparatus inoperable. 

In all cases, the licence holder must take into account the presence of other hazardous materials, for example: beryllium, mercury, cadmium, etc. The licence holder should seek guidance from their local environmental agency on disposal requirements for such material or investigate possible recycling options.  

Once destroyed, the apparatus ceases to meet the definition of a controlled apparatus and is therefore no longer subject to regulatory control. Individual dismantled parts are not deemed to be controlled apparatus.

If apparatus is to be disposed of because it has ceased to function, a critical component should still be removed so that repair is not possible.

In the case of apparatus containing radioactive material, removal of the material means the apparatus is no longer ‘controlled’.  However, depending on the activity of the material removed, it may still be subject to regulatory control and need to be authorised by a licence. 

Where disposal to landfill is proposed, the licence holder should ensure that the removed critical components are discarded separately to the rest of the apparatus unless they are to be retained as spare parts. This is to prevent any chance of them being recombined or repaired. Recycling should be considered where possible.

Transfer a source out of ARPANSA's jurisdiction

Sources are often sold, leased, hired, or given away to a person or organisation in another jurisdiction - such action is regarded as a ‘transfer’. This includes the return of controlled material to the original manufacturer or supplier in another jurisdiction or in some cases overseas.  

In the majority of cases prior approval is required for a source to leave ARPANSA’s jurisdiction.  However, paragraph 65(1)(c) of the Regulations provides for certain Group 1 controlled apparatus to be returned to the supplier without prior approval as noted above.    

Particular attention is required when proposing to dispose of multiple low activity sources in a single shipment. The activity of all sources must be aggregated (using the method in Schedule B of RPS 11) to determine if additional security arrangements apply.

 

Additional requirements for security enhanced sources:

Licence holders must be aware of the additional security arrangements for security enhanced sources, in particular the requirement for an endorsed transport security plan – see RPS 11 (para 5.3)

It is important that receipt of the source is confirmed at its final destination particularly if overseas.   

If the final destination is outside Australia the licence holder must ensure that the required documentation is completed noting that an ARPANSA Export Permit is required for the export of high activity sources. For the definition of a high activity source and information about how to apply for an export permit please see Export permits | ARPANSA.

Transfer a security enhanced source to another ARPANSA licence holder

Under RPS 11 (2.1.11) the transfer of a security enhanced source must have prior approval from the CEO even if the transfer is between ARPANSA licence holders.

Licence holders must comply with the additional security requirements, in particular the requirement for an endorsed transport security plan as per para 5.3 of RPS 11.  

How to apply for approval to dispose of a source

Licence holders seeking approval to dispose of a source should use the Request for approval to dispose of a source. Completed forms should be sent to licenceadmin@arpansa.gov.au.

Licence holders must comply with their obligations under the following codes:

Follow up actions

Maintaining an accurate inventory

Following physical disposal, the status of the source in the source inventory workbook (SIW) should be changed to ‘Transferred’ or ‘Disposed’ and the date recorded.   

Reporting compliance 

Compliance reports submitted by licence holders must include summary information about disposals that have occurred during the reporting period. This includes disposals that did not require prior approval to ensure that databases are updated.    

 

   

 

Regulatory Guide - Applying for a licence for a radioactive waste storage or disposal facility (ARPANSA-GDE-1736)

This regulatory guide is designed to assist a controlled person when applying for a facility licence under section 32 of the Australian Radiation Protection and Nuclear Safety Act 1998.

It should be read when completing the Licence Application Form

Additional information can be found in supplementary document Radioactive Waste Storage and Disposal Facilities: Information for Stakeholders.

 

Associated forms

Applicants should use the nuclear installation or prescribed radiation facility application form depending on the type of facility:

1. Introduction

1.1 Purpose and scope

This regulatory guide provides information for controlled persons (referred to as ‘the applicant’ in this guide) applying for a licence for a radioactive waste storage or disposal facility and associated ancillary facilities under the Australian Radiation Protection and Nuclear Safety Act 1998 (the Act) and the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations)1. It supersedes the regulatory guide Licensing of Radioactive Waste Storage and Disposal Facilities (REG LA SUP 240L v2) issued in March 2013. 

The guide addresses issues that should be considered when applying for a licence for a controlled facility designed to store large quantities of low and intermediate level radioactive waste including long term storage of such waste, noting that a storage facility may be operational for more than a century; or dispose of similarly large quantities of low level radioactive waste in a near-surface disposal facility. It is applicable to waste generated in activities carried out under a licence issued under the Act and only to waste generated in Australia, including waste generated during reprocessing overseas of spent nuclear fuel from nuclear reactors operated in Australia2.

The guide is not applicable to:

  • short-term storage of small quantities of waste
  • disposal of small quantities of low level waste at the point of generation3
  • management of waste generated during mining and milling of ores
  • waste facilities under state or territory jurisdiction.

The guide provides information on documentation, relevant to the type of facility and in line with a graded approach, to be submitted in order for the CEO of ARPANSA to make an informed assessment of whether the proposed facility sufficiently addresses the matters that should be taken into account by the CEO in making a licensing decision that is not in conflict with the object of the Act, which is to protect the health and safety of people, and to protect the environment, from the harmful effects of radiation. Failure to provide sufficient and satisfactory information may cause delays in the review of the application, or result in the application being declined.

1.2 General aspects of radioactive waste management

In Australia, radioactive waste is generated from a wide range of activities involving radiation sources, facilities and nuclear installations in the processing, use or generation of radioactive material in medicine, industry and research. 

Effective and safe management of radioactive waste requires an appropriate classification of the waste. An internationally acknowledged scheme for classification of radioactive waste has been developed by the International Atomic Energy Agency (IAEA) in IAEA Safety Series GSG-1 Classification of Radioactive Waste (2009), which comprises six classes of radioactive waste. Australia has adopted this classification system through Radiation Protection Series RPS G-4 Guide for Classification of Radioactive Waste (2020).

The most important factor that determines the classification of the waste is the manner by which it can be safely disposed. This depends on the amounts and concentrations of radioactive substances, their properties including half-life (the time it takes for the activity to decay to half its original level), and other properties such as heat generation and chemical nature of the waste.

Radioactive waste storage and/or disposal facilities are components of a system for waste management that also includes transport routes from sites of waste generation or interim storage to the waste management facility. Additionally, radioactive waste from various activities may require predisposal management such as treatment and conditioning in ancillary facilities to ensure that it conforms to the waste acceptance criteria for processing, storage and emplacement into the disposal facility. 
Transport of waste to, from and between facilities must conform to requirements in the Transport Code RPS C-2 Code for the Safe Transport of Radioactive Material (2014).

Disposal refers to the emplacement of radioactive waste into a facility or a location with no intention of retrieving the waste. Disposal options are designed to contain and isolate the waste from the accessible biosphere by means of engineered and natural barriers in a manner that is commensurate with the hazard4.

Storage refers to the retention of radioactive waste in a facility or a location with the intention of retrieving the waste for conditioning (if needed) and ultimate disposal. The period of storage may vary depending on the waste and the type of facility. However storage is always an interim measure. 

A storage facility may be located at a site where radioactive waste is generated; it may comprise a separate facility or it may be co-located with a disposal facility.

1.3 Structure of this guide and explanation of terms

Sections of this guide deal with the matters in section 53 of the Regulations that the CEO must take into account when deciding whether to issue a facility licence. The CEO will require an applicant to provide information to address those matters. 

Section 46 of the Regulations lists the kinds of documents and information that the CEO may ask for in relation to an application. Depending on the activity to be authorised by the licence, the CEO will require whichever of those documents and information are relevant. 

Matters in section 53 of the Regulations are listed below, with an indication as to where they are dealt with in this regulatory guide.

Matters specified in section 53 of the RegulationsRelevant section
(a) whether the application includes the information asked for by the CEOSection 2: Information requested
(b) 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 environmentSection 3: Undue risk
(c) whether the applicant has shown that there is a net benefit from carrying out the conduct relating to the controlled facilitySection 4: Net benefit
(d) 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 factorsSection 5: Optimisation
(e) whether the applicant has shown a capacity for complying with these regulations and the licence conditions that would be imposed under section 35 of the ActSection 6: Capacity to comply
(f) whether the application has been signed by an office holder of the applicant, or a person authorised by an office holder of the applicantAppendix 2
(g) if the application is for a facility licence for a nuclear installation—the content of any submissions made by members of the public about the applicationNot dealt with in this regulatory guide

Section 32(3) of the Act requires that in making a decision in relation to an application for a facility licence, the CEO must take into account international best practice in relation to radiation protection and nuclear safety. Information and documents that the CEO asks for in relation to a licence application will include information relevant to international best practice.

Additional information is provided in the appendices as follows:

  • Appendix 1 provides generic information on how to complete and lodge a licence application
  • Appendix 2 provides information on how a licensing decision is reached
  • Appendix 3 provides information on how an applicant can appeal against a decision.

Terms and their definitions in this guide are the same as in the Act and Regulations. To the extent terms that are used here are not found in the Act and Regulations, their use is aligned with the IAEA Safety Glossary 20075.

Use of the term ‘safety’ or the phrase ‘health and safety’ in this regulatory guide refers to radiation, waste, transport and nuclear safety, emergency management, and nuclear security, i.e., actions taken to achieve protection against radiation risks6. It does not refer to safety in the sense used in work health and safety legislation, or in other safety legislation.

Some concepts, principles and processes related to waste management are outlined in a supplementary document, Radioactive Waste Storage and Disposal Facilities: Information for Stakeholders. The information document can be read in conjunction with this regulatory guide as a source of explanations and background, but should not be considered a guide.

2. Information requested

Section 46 of the Regulations gives the CEO the power to ask an applicant for some or all of the information and documents mentioned in section 46 and other information about the application if appropriate.

This regulatory guide indicates the documents and information from Schedule 3 that the CEO will require as part of the application. This regulatory guide also indicates the documents and information that should be submitted by the applicant to enable the CEO to take into account the matters in section 46 of the Regulations as relevant to the type of facility and stage in the licensing process.

Use of ‘must’ in this guide indicates a mandatory legislative requirement. Use of ‘should’ statements indicates the CEO’s expectations in terms of what would be considered a complete application. A graded approach should be applied by the applicant to ensure that the depth and detail of information is appropriate to the nature of the facility and the activity to be authorised. 

Under paragraph 53(b) of the Regulations, the CEO must assess whether the application includes all of the information asked for by the CEO, as relevant to the specific stage in the licensing process (see further Section 2.2). 

A licensing decision will not be made unless and until the information provided by the applicant demonstrates that the proposed conduct can be carried out without undue risk to the health and safety of people and the environment. For facilities, this information will be collated in a safety case. The safety case is the collection of scientific, technical, administrative and managerial arguments and evidence in support of the safety of a facility, covering the suitability of the site and the design, construction and operation, the assessment of radiation risks, and assurance of the adequacy and quality of all of the safety related work that is associated with the facility. 

Information provided in the safety case should support the applicant’s conclusions in relation to items (b) through (f) in section 53 of the Regulations (see Section 1.3) and will, where applicable, support consultation in relation to item (h).

2.1 The safety case

Objective: The applicant should prepare and maintain a safety case that allows for a full understanding of all aspects relevant to the safety of the controlled facility; it should contain references to supporting material. It should be in a form suitable to be used as the basis for consultation with all stakeholders on the safety of a facility for storage or disposal of radioactive waste as well as any ancillary facilities that may be part of the system for waste management7.

The safety case should outline all safety-related arguments the applicant draws on in support of the application. It should include information on the consultation activities undertaken by the applicant prior to seeking a licence and during development of the safety case and what conclusions have been drawn from such consultation. 

A table outlining the information that the applicant should submit as part of the safety case is at Schedule 1, including references to relevant sections in this regulatory guide. The schedule contains the generic elements applicable to all stages in the licensing process, as well as specific elements that should be introduced at various stages in the licensing process. Note that the safety case is a living document; specific elements will continue to be relevant for subsequent licensing stages and need to be updated in the safety case. 

A major component of the safety case is the safety assessment, which includes the safety analysis. Important elements of the safety assessment are radiological impact on humans and the environment, site and engineering aspects, operational safety, non-radiological impacts, and the management system. Safety should be achieved by applying the principles of defence in depth, optimisation, and, as relevant, through the use of best available technique8. The safety analysis is the evaluation of the potential hazards associated with a facility or activity, documented in a safety analysis report (SAR). 

The safety case will be the main source of information for stakeholders during the consultation phase9. As such, the CEO will require a summary of the safety case in plain non-technical language, to facilitate communication and consultation.

The applicant should take into account the Act and Regulations, regulatory guidesrelevant codes, standards and guides, all available from ARPANSA’s website when preparing the safety case. 

The CEO will require information about compliance with other legislation relevant to the protection of health and safety of people and the environment such as the Environment Protection and Biodiversity Conservation Act 1999 (the EPBC Act) and the Nuclear Non-Proliferation (Safeguards) Act 1987. An application may be submitted to ARPANSA even if the environmental impact statement (EIS) or outcomes of the environmental assessment are not available. Assessment work by both agencies may continue in parallel but a licensing decision cannot be made by ARPANSA until the EIS and assessment of the EIS are provided.

As there is an obligation on the CEO to take international best practice into account in regulatory decision making, it is incumbent on the applicant to demonstrate how international best practice has been considered in the safety case. Information on international risk assessments and standards that are relevant in this context is available at the international best practice page. A licence application should also draw on relevant design concepts, operational experience, and decommissioning and closure experience from facilities in other countries with an advanced infrastructure for safety.

The safety case should acknowledge the existence of any unresolved issues and should provide information on work proposed to resolve these issues in future stages of the licensing process. Issues that have been resolved with ARPANSA and other stakeholders should be documented and form part of the safety case.

The safety assessment should also consider the safety implications of any proposed co-location of different types of radioactive waste management facilities. In the case of co-location, each facility would in most cases require a separate application and safety case, addressing the relevant requirements for each stage of facility development. The safety of transport to, from and between radioactive waste management facilities should also be considered noting that the responsibility for transport of waste to a storage or disposal facility lies with the waste owner. This may require prior approval of a transport safety and/or security plan by ARPANSA.

It is expected that the safety case will be updated for each stage of licensing or otherwise as required by the CEO of ARPANSA. For each stage, it should provide enough information about the subsequent licensing stages to allow for an informed decision on the feasibility of the storage and/or disposal concept, as well as of the system for radioactive waste management.

With each new licensing stage, the safety case will become increasingly informed by experience gained during previous stages and by safety and security reviews, if any such review has been performed. For a storage facility, the safety case should outline plans for the final management of the waste in storage, including its disposal.

The IAEA requirements for a safety case are outlined in: 

Guidance from IAEA on how to prepare a safety case and the typical components can be found in:

The applicant is encouraged to implement a graded approach and direct efforts and resources to the matters that are most significant for protection of the health and safety of people, and of the environment.

2.2 Information specified in the Regulations

Subsection 46(2) of the Regulations outlines extra information that the CEO may ask for. 

For a facility covered by this regulatory guide, the information below will be required by the CEO as part of the application and should form part of the safety case.

The schedule differentiates between the different stages of licensing; however, as stated earlier, an application should also go into some detail about subsequent licensing stages. That is, the level of detail of information required at the various stages of licensing will vary and should be proportionate to the particular stage. For example, an emergency management plan is not expected to be as detailed in the application to site a facility as in the application to operate the facility.

General information

The CEO will require the following information as part of the safety case before a licensing decision can be made
1(a)The applicant’s full name, position and business address
1(b)A description of the purpose of the facility that is to be authorised by the facility licence
1(c)A detailed description of the controlled facility and the site for that facility
1(d)Plans and arrangements describing how the applicant proposes to manage the controlled facility to ensure the health and safety of people and the protection of the environment

Note that further details relevant to 1(d) are outlined in Sections 3 and 5, and in Appendix 2, of this regulatory guide.

Prepare a site for a controlled facility

The CEO will require the following information as part of the safety case before a licensing decision can be made
1(a)A detailed site evaluation establishing the suitability of the site
1(b)The characteristics of the site, including the extent to which the site may be affected by natural and human events
1(c)Any environmental impact statement (however described) requested or required by a Commonwealth State or Territory government agency in relation to the site or the facility, and the outcome of the environmental assessment10

The selection of a site for a controlled facility requires that the conceptual design has been established so that the suitability of the site can be adequately assessed in relation to the general safety features of the facility. The performance of the barriers (engineered and natural) that separate the e from the biosphere should be well understood and documented in the safety assessment and through the first iteration of a safety analysis report (preceding the preliminary safety analysis report required in the construction stage). The characteristics of the site as well as its evolution in terms of such things as geology, hydrology, biology, demography and land use should be well characterised.

Apart from a detailed site characterisation, all information may not be developed in full detail at the time the siting application is submitted and will be gradually refined as the safety case evolves. However, the application should provide sufficient information to demonstrate that the facility can provide protection of the health and safety of people and of the environment under all reasonably foreseeable circumstances at the time of application.

Construct a controlled facility

The CEO will require the following information as part of the safety case before a licensing decision can be made
2(a)The design of the controlled facility, including ways in which the design deals with the physical and environmental characteristics of the site
2(b)Any fundamental difficulties that will need to be resolved before any facility licence relating to the facility is issued
2(c)The construction plan and schedule
2(d)A preliminary safety analysis report that demonstrates the adequacy of the design of the facility and identifies structure, components and systems that are safety related items
2(f)The arrangements for testing and commissioning safety-related items

The safety case for the construction phase should include a preliminary safety analysis report (PSAR) that takes into account the detailed design of the facility and demonstrates that the safety issues have been satisfactorily resolved. The safety case should demonstrate that construction will result in a facility that has the potential to be licensed to operate and be decommissioned or closed (as appropriate) while providing for the protection of health and safety of people and the environment.

Possess or Control

The CEO will require the following information as part of the safety case before a licensing decision can be made
3(a)Arrangements for maintaining criticality safety during loading, moving or storing nuclear fuel and other fissile materials at the facility
3(b)Arrangements for safe storage of controlled material and maintaining the facility

The safety case for the possess or control phase should detail arrangements for maintaining the facility in the event that such a licence is required before radioactive waste is received by the facility. This could eventuate if there is a delay between the construction and operation phases.

Operate a controlled facility

The CEO will require the following information as part of the safety case before a licensing decision can be made
4(a)Description of the structures, components, systems and equipment of the facility as they have been constructed
4(b)Final safety analysis report that demonstrates the adequacy of the design of the facility, and includes the results of commissioning tests
4(c)Operational limits and conditions of the facility
4(d)Arrangements for commissioning the controlled facility
4(e)Arrangements for operating the controlled facility

Following construction, the PSAR should be updated to address the design information for the facility including the operational limits and conditions within which the facility must operate. The term 'final SAR' (FSAR) is used for the updated version that must be submitted to ARPANSA with an application for a licence to operate a facility as part of the updated safety case.

Decommission or close a controlled facility

The CEO will require the following information as part of the safety case before a licensing decision can be made
5(a)Decommissioning plan for the facility
5(b)Schedule for decommissioning the facility
5(c)The results of decommissioning activities at the controlled facility
5(d)Details of any environmental monitoring program proposed for the site

Decommissioning is applicable to a radioactive waste storage facility and to ancillary infrastructure necessary for predisposal management including infrastructure associated with a disposal facility before closure of the facility. 

The decommissioning plan should be part of the safety case from the outset and will be refined until such time an application to decommission the facility is submitted. It will at that time also be informed by operational experience including information about any events that might be relevant to the safety of decommissioning.

A final decommissioning report should summarise: 

  • decommissioning undertaken
  • dismantling of the facility
  • waste management including clearance of radioactive materials or objects from regulatory control
  • the final status of the site at the time of release from regulatory control or of conversion to other use
  • any remaining restrictions on the site. 

The final decommissioning documentation should show, as far as practicable, that all radioactive materials present at the beginning of decommissioning are accounted for and their ultimate destination is confirmed.

Release of the site or facility from regulatory control may be achieved progressively for parts of the facility or site or with restrictions to ensure protection of people and the environment. A plan for ongoing control, maintenance and surveillance of any area released with restrictions should be prepared by the licence holder and approved by ARPANSA. Legal and financial arrangements should be made for implementation of the plan.

For a disposal facility the safety case for operation of the facility should consider the safety after closure of the facility. The safety of the disposal facility after closure should take into account the expected range of possible developments affecting the disposal system and events that might affect its performance including those of low probability. Further details of the post-closure phase are described in Section 5.2.2 of this document and specific requirements for the final closure plan are presented in Schedule 1.

The CEO’s consent must be obtained before a licence can be surrendered and a site released from regulatory control.

3. Undue risk

Under paragraph 53(c) of the Regulations, the CEO must consider whether the information provided by the applicant establishes that the proposed conduct can be carried out without undue risk to the health and safety of people and to the environment. For this purpose, the applicant should demonstrate 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 abnormal occurrences.

Guidance on optimisation of protection in terms of radiation doses and risks are given in Section 5 of this regulatory guide. The systematic approach to achieve the appropriate level of protection is captured under Plans and arrangements for managing safety as outlined below.

3.1 Plans and arrangements for managing safety

Objective: The applicant should demonstrate effective systems and processes that provide assurance that the controlled facility can be sited, constructed, operated, decommissioned and closed in a way that does not pose undue risk to the health and safety of people and to the environment.

The management system is key to establishing a system for leadership and management for safety; it should provide assurance that the operator has systems and procedures in place to identify, characterise and manage all safety issues including ranking the relative importance of risks so that available resources are deployed efficiently and effectively.

The management system should be designed to foster and promote a culture of safety which takes into account human factors such as attitudes and behaviour as well as the general mindset by which all workers including senior management approach safety. These factors should interact with the technological and organisational factors in a way that promotes holistic safety (often referred to as systems safety) which is considered a best practice approach to safety management. A holistic approach to safety ensures the technology is safe to use, people perform tasks safely, and the organisation overall is managed safely.

ARPANSA has developed a Holistic Safety Guideline on the implementation of holistic safety to which applicants may refer.

Guidance on what the CEO would expect to be included in plans and arrangements is provided in Regulatory Guide: Plans and arrangements for managing safety (2017).

The applicant should include in the safety case information that demonstrates leadership and management for safety, relevant to all safety aspects and licensing phases, documented in a management system

The management system should define how the applicant proposes to manage the controlled facility to ensure health and safety of people and protection of the environment. The applicant should provide the following information as per paragraph 46(1)(d) of the Regulations:

  • the arrangements for maintaining effective control of the facility
  • the safety management plan for the facility
  • the radiation protection plan for the facility
  • the radioactive waste management plan for the facility
  • the security plan for the facility
  • the emergency plan for the facility
  • the environment protection plan for the facility

The interdependencies between different components of the waste management system and their collective contribution to the over-all safety of the facility should be considered.

In the case of co-located facilities, the management system should address the elements which are common to these facilities and their interrelationships as well as the safety implications of co-location.

The management system should address holistic safety, that is, the human, organisational and technical elements, and their interrelations in managing the facility safely.

4. Net benefit (justification)

Objective: the applicant should demonstrate that the controlled facility provides an overall net benefit.

The principle of justification in the internationally adopted system for radiological protection states that any activity which introduces a radiation source or exposure must do more good than harm, that is, there is net benefit.
Under paragraph 53(d) of the Regulations, the CEO must consider whether the applicant has shown that there is a net benefit from carrying out the conduct related to the controlled facility. 

For radioactive waste storage or disposal facilities, the analysis of justification should take into consideration the conduct relating to the controlled facility including any predisposal management as well as the risks and benefits of the activities and facilities that generate further waste. For waste that already exists, justification cannot be assessed; however, any decision to manage it should consider optimisation of protection (see Section 5).

The risks associated with the continuation of current practices (the ‘zero option’) and with reasonable alternatives to the proposed system should be considered by the applicant. 

It is acknowledged that in many cases, decisions relating to benefit and risk are taken at the highest levels of government11. In other cases, a regulator, such as the CEO of ARPANSA, may determine whether proposed facilities and activities are justified. 

The applicant should include in the safety case information that demonstrates that the proposed facility is justified

The applicant should provide:

  • information on current and future activities generating waste destined for the facility and the benefits and risks associated with the generation of waste that contribute to such waste streams
  • an analysis of potential alternative technologies than the ones currently generating the waste or other ways by which the same benefit can be achieved with less risks
  • an analysis of alternative options for managing (predisposal management including storage, and disposal) the current waste inventory and projected waste streams including the option of continuing current practices and the associated risks.

5. Optimisation

Under paragraph 53(e) of the Regulations, the CEO must consider whether the applicant has shown that the magnitude of individual doses, the number of people exposed, and the likelihood that exposures will happen, are as low as reasonably achievable, having regard to economic and social factors. This internationally adopted principle for radiological protection is referred to as optimisation.

Dose limits have been set in Division 2 of the Regulations at levels that provide a high level of protection for individuals from detrimental effects of radiation exposure. The dose limits and provisions regarding averaging times and calculations of committed dose outlined in Division 2 apply in their entirety to facilities covered by this regulatory guide.

Optimisation ensures that the dose limits are very rarely exceeded as exposures are normally optimised far below such limits. Optimisation is often guided by a dose constraint which is set at a fraction of the dose limit and is specific to the activity or facility (the ‘source’) that is the cause of the exposure. Planning, design and management should be such that exposures over this constraint are not expected to occur but are maintained as low as reasonably achievable where economic and social factors are taken into account.

5.1 Protection of workers

Objective: The applicant should demonstrate that systems, structures and components, and the management of the controlled facility provide optimised protection of workers during operation and decommissioning and that worker protection is optimised during monitoring and remedial works including in the post-closure phase of a disposal facility.

The applicant should propose a dose constraint for workers below which protection will be optimised. The expectation is that the constraint would not normally be set higher than 5 mSv effective dose per year12 for workers in a facility for storage or disposal of radioactive waste.

Dose limits apply and optimisation of worker protection should also be implemented during remedial work whether this work takes place during the operation, decommissioning or post-closure phases.

Dose records provide a means of verifying that efforts to optimise radiation protection have been effective. 

5.2 Protection of the public

Objective: The applicant should demonstrate that systems, structures and components, and the management of the controlled facility provide optimised protection of the public during operation, decommissioning and post closure.

The engineered barriers should be designed and maintained, and for the long term the natural barriers should be of a nature so that the containment of the radioactive waste will be effective and will withstand reasonably foreseeable disruptive events over the time period the waste poses radiation risks of concern. 

The applicant should demonstrate the protective capability of the facility by carrying out exposure modelling based on a set of clearly defined and explained assumptions13. This includes defining and using a representative person, affected by reasonably foreseeable exposures from the facility, or reasonably foreseeable exposures resulting from handling, including transport, of the waste (see ICRP Publication 101a Assessing Dose of the Representative Person for the Purpose of the Radiation Protection of the Public (2006) for details on the representative person).

5.2.1 The operational phase

The applicant should demonstrate that the protective capability is optimised including how different design alternatives have been considered in the optimisation process and support the analysis by exposure modelling.
For a storage facility, the design and maintenance during the operational phase should aim to permit abandonment of the site and unrestricted access after decommissioning (‘green field’) or—if so authorised—use for different purposes including for activities that may require management of radiation risks. 

5.2.2 Post-closure phase

The post-closure phase for a disposal facility includes the normal and natural evolution of the systems, structures and components that contribute to safety and disruptive natural events that may impact on safety, either immediately or in the future.
Disruption may also be caused by inadvertent and planned intrusion, accidents and reckless activities, and intrusion with malicious intent.

Normal evolution of the facility and its surroundings

Processes that govern the performance of the barriers can be foreseen with reasonable certainty and are linked to the features of the facility. The period during which ongoing control of the facility will take place should be defined by the applicant. During this phase, and taking reasonably foreseeable natural events into account, the protective capability of the facility is expected to be at least similar to the protective capability during the operational phase (features, events and processes are commonly referred to as FEPs).

Following termination of controls, or for time periods beyond several tens to a few hundred years (depending on the type of facility), it is reasonable to analyse the facility’s protective capability in terms of risk rather than in terms of exposure or dose. 

The concept of radiation risk as used in this regulatory guide considers the probability of an event occurring with the probability of harm (the implications for the health of people) should the event occur. A high probability event with a low probability of harm may thus pose the same risk as a low probability event with high probability of harm. The applicant should define the scenarios that govern the risk estimates. This can be done deterministically by defining likely scenarios and assigning parameter values to FEPs. The analysis can be supplemented by performing a number of realisations in a probabilistic approach to the assessment. Information should be provided on the time frames within which the risk is assessed.

For normal evolution including reasonably foreseeable natural disruptive events, optimisation and use of best available technique should aim at reducing the annual risk for health detriment14 for a member of the public to in the range 10-5 to 10-6 or less (one in a hundred thousand to one in a million). This range takes into account the various means (and inherent uncertainty) in predicting the characteristics, including behaviour and land use of future populations including the representative person, over time periods of centuries and beyond. The applicant should provide information on how the risk may vary over time.

Accidents and severely disruptive natural events

Severely disruptive events include accidents and natural events of a magnitude that is well outside of the ordinary, e.g. seismic events outside the range of what has been recorded or can be reasonably expected or flooding caused by similarly extreme weather conditions. The consequences of multiple and simultaneous events should be analysed as well as the long term consequences of such events for the protective capability of the facility.

The applicant should separately and deterministically assess and record a suite of scenarios that involve accidents and severely disruptive natural events that may result in an annual dose of ≥1 mSv effective dose (annually or in immediate association with the event) if such scenarios exist and explain the rationale for identifying the scenarios.

Human intrusion

Planned intrusion may result from any future attempt to alter the engineered barriers or retrieve the waste or any other reason that today can only be speculated. They would be considered planned actions. The framework for institutional control and preservation of information should be developed with the potential for such future planned actions in mind.

Any design features aimed at facilitating retrieval of waste should not reduce the protective capability of the facility.

The applicant should address possible scenarios involving inadvertent human intrusion into the disposal facility in the post-closure phase. The consequence of intrusion for the protective capability of the facility should be analysed.

If such intrusion is expected to lead to an annual dose of less than 1 mSv effective dose to the intruder or those living close to the site then efforts to reduce the probability of intrusion or to limit its consequences are likely not warranted.

Where it is calculated that inadvertent human intrusion could result in doses of between 1 and 10 mSv effective dose for any human associated with the intrusion (annually or in immediate association with the intrusion) further evaluation of the particular scenario is needed and reasonable efforts may be warranted to reduce the probability of intrusion or to reduce the consequences. 

If doses of greater than 10 mSv effective dose associated with the intrusion are calculated for an individual from a plausible but inadvertent human intrusion scenario (annually or in immediate association with the intrusion) additional controls should be put in place to further limit the possibility of intrusion or to limit the consequences to below that dose figure. This may involve re-design of the facility, changes to the waste acceptance criteria or segregation of the radioactive substances giving rise to the higher dose.

Deliberate intrusion may also arise from acts with malicious intent. The concern here is primarily with the safety of those indirectly affected by the intrusion. The arrangements for safety should reduce the worker, public and environmental risks associated with such intrusion to levels that are as low as reasonably achievable where economic and social factors are taken into account.

Remediation preparedness

For any remedial actions that are deemed justified following reckless actions, accidents and disruptive events including human intrusion a reference level of 10 mSv annual effective dose or less should be applied for protection of the public. Remedial actions should be planned and optimised so that the resulting annual effective dose is below the selected reference level. Worker exposures must be below the dose limit for workers and should be optimised. Information on remediation preparedness should include the following, as relevant:

  • division of responsibilities for remediation
  • the role of stakeholders
  • approaches to defining remediation targets and end states as well as generic waste management plans
  • potential methods and technology available for environmental remediation.
Time frames

The applicant may impose a time cut-off in the assessment of passive safety. The reason for the cut-off should be explained. 

In the case of time frames beyond several hundreds of years, increased attention needs to be placed on analysis of implications for safety of long-term climatic and other environmental trends in order to form a view on the appropriateness of the protective capability of the facility.

The applicant should include as part of the safety case information that demonstrates that all reasonable steps have been taken to ensure that protection of workers and the public is optimised

The applicant should optimise the protection of workers and in doing so:

  • establish dose constraints to guide optimisation efforts
  • optimise worker protection during any monitoring or remedial work

The applicant should optimise protection of the public in the operational phase of a storage or disposal facility and in doing so:

  • model exposures of representative individuals and define what assumptions that have been made about exposure pathways and their characteristics, and about the characteristics of the exposed groups including the representative individuals. 

The applicant should optimise protection of the public and apply best available technique to the design and to the safety of the post-closure phase of a disposal facility and in doing so:

  • aim for reducing risks of detriment to between 10-5 and 10-6 per annum or less, including during reasonable foreseeable natural disruptive events, using the nominal risk coefficients in ICRP Publication 103 and provide information on the assumptions used in the risk calculations
  • identify scenarios including disruptive events, accidents, and intrusion (inadvertent or with malicious intent) that may lead to effective doses over 1 mSv annually or in association with the event
  • for intrusion scenarios leading to effective doses in excess of 10 mSv (annually or in association with the event) consider alternative designs or methods to segregate the waste
  • for planned remedial actions, comply with dose limits for workers and optimise protection against a reference level of 10 mSv effective dose per year or less.

The applicant should carry out calculations demonstrating the protective capability of a disposal facility in the future and in doing so:

  • analyse the features, events and processes governing the protective capability of the engineered and natural barriers over a time period that is commensurate with the hazard of the disposed waste.

5.3 Protection of the environment

Objective: The applicant should demonstrate that the systems, structures and components, and the management of the controlled facility provide protection of the environment and that the facility does not adversely impact an area that has special environmental attraction or appeal, is of notable ecological significance, or is the known habitat of rare fauna or flora.

In order to assess the impact of a proposed radioactive waste storage or disposal facility on the environment the applicant should undertake a screening assessment of exposures to wildlife. If a screening assessment that uses a cautious approach indicates that incremental exposures to relevant wildlife in the natural environment are likely to be below a dose rate of 10 microGy per hour, no further assessment will be deemed necessary15. If the assessment indicates higher dose rates, further assessments should be performed to estimate the potential level of impact on wildlife. Guidance is provided in ARPANSA RPS G-1 Guide for Radiation Protection of the Environment (2015).

An environmental management plan should be established for the disposal site prior to commencement of construction and operation. The purpose of the plan is to set out management objectives and practices which will provide for the safe and environmentally sound management of the facility during its construction, operational and post-operational phases.

Time frames and scenarios used for the analysis of long-term protection of people should be applied also when analysing long-term protection of the environment.

The applicant should include as part of the safety case information that demonstrates that the environment is protected

The applicant should characterise the environment, including any unique features requiring particular attention in terms of conservation that may influence the feasibility of the site. 

The applicant should, before the construction of a facility, establish baseline information of the site regarding its radiological characteristics, to inform the development of the environment management plan and environmental monitoring.

The applicant should, as parallel to the optimisation of protection of people, consider exposures of organisms in the natural environment using scenarios and time frames that have been used when analysing long-term protection of people and in doing so:

  • analyse the characteristics of the natural and semi-natural environment in the facility’s surroundings
  • take into consideration that dose rates incurred by wildlife in such environments below 10 µGy per hour and determined or predicted using cautious approaches and methodologies may serve as an indicator that wildlife is adequately protected.

5.4 Security

Objective The applicant should demonstrate that systems are in place to prevent unauthorised access, theft and acts with malicious intent including actions that would contribute to proliferation of nuclear material considering the security vulnerabilities of the controlled facility and entire system for waste management.

The approach to security should be guided by the optimisation principle and be benchmarked against the dose and risk reduction strategies outlined above. The interaction and interface between measures to ensure safety on one hand and security on the other, should be taken into consideration so that actions taken to ensure security do not inadvertently impact on safety and vice versa.

If radioactive waste that is also nuclear material is to be managed then the security systems and infrastructure protecting the nuclear material will need to comply with the requirements under the Amendment to the Convention on the Physical Protection of Nuclear Material and the IAEA Nuclear Security Recommendations on Physical Protection of Nuclear Material and Nuclear Facilities. This is managed through permits issued under the Nuclear Non-Proliferation (Safeguards) Act 1987 by the Australian Safeguards and Non-Proliferation Office (ASNO).

The applicant should include as part of the safety case information that demonstrates that people, property, society and the environment is protected from malicious intent

The applicant should:

  • submit a security plan that covers security issues including transport of waste where relevant 
  • assess and manage any conflicts or tension between security and safety

6. Capacity to comply

Objective: The applicant should demonstrate that adequate capacity is sustained for the full life-cycle of the controlled facility and records are established and preserved for the future.

Under paragraph 53(f) of the Regulations, the CEO must consider whether the applicant has shown a capacity for complying with the Regulations and the licence conditions that would be imposed under section 35 of the Act.

The applicant should demonstrate that it has the capacity of managing safety over the life-time of the facility. It should demonstrate adequate human and financial resources, the necessary skills for leadership and management of safety, and long-term sustainability. It should also provide information of its record of managing similar facilities or relevant information that provides confidence in its ability and capacity to do so.

The approximate timing and conditions for termination of the responsibility of the operating organisation should be defined for example, after decommissioning or closure. Where relevant, the terms and conditions for continued institutional control should be clarified.

Records relevant to safety should be established and arrangements should be made for their long-term maintenance including determining locations where the records are to be kept. Commonwealth government agencies must comply with the requirements of the Archives Act 1983 (Cwlth).

The applicant should demonstrate adequate capacity to sustain safety over the life-cycle of the facility

The applicant should, unless the information is already available to ARPANSA, demonstrate that:

  • it is adequately resourced financially
  • possesses the necessary competencies, skills and experience
  • it is able to sustain its activities including safety during the expected time of ongoing control of the facility.

Safety-related records should be established and arrangements made for their long-term maintenance.

Schedule 1: Information that should be submitted as part of the safety case

General information relevant to all stages of a controlled facility

The applicant should submit a safety case with the licence application that includes:

  • the information requested in section 46 of the Regulations relevant to the specific licensing stage (see Section 2.2)
  • all safety-related arguments the applicant draws on in support of the application. A safety case document may reference detailed supplementary documentation but should be comprehensive enough to allow all stakeholders to form a view on the safety of the facility
  • a summary in plain language to facilitate communication during the consultation process16.

The safety case should be updated for each new stage in the licensing process, drawing on input during consultation and experience gained during establishment of the facility, include information on remaining unresolved issues and the plan towards their resolution.

It should contain enough information on future licensing stages to allow for an informed decision on safety during the facility’s life cycle.

Compliance with legislative and regulatory requirements

  • these include the Act and Regulations, other Acts as relevant, codes (RHS and RPS) as relevant, and to take into account ARPANSA regulatory guides as relevant.

Approach to international best practice

  • the radiation protection, and nuclear safety and security objectives as a part of the siting, design, operation, decommissioning and closure; compared with those laid out in the international framework for safety, security and radiation protection documented in international standards (e.g. IAEA safety standards and nuclear security guidance)
  • technical standards for construction, materials and other features, relevant to safety
  • experience from siting, construction, operation, decommissioning and closure of similar facilities in countries with an advanced infrastructure for safety.

Protection of the health and safety of people and of the environment

  • demonstration that the application meets the health and safety objectives of relevant legislation
  • justification for the application in terms of net benefit, i.e. that there is more good than harm (see Section 4)
  • demonstration that protection is optimised and that the environment is protected (see Section 5)
  • a safety assessment including an iteration of the safety analysis report (SAR) relevant to the licensing stage

Capacity to comply – see Section 6

Application fee

The application is not valid without the appropriate fee. Applicants should refer to Division 4 of the Regulations to determine the appropriate application fee.

Assessment of the application cannot begin until the fee is received. Arrangements should be made for electronic payment of the fee. 

Submitting the application

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

Appendix 2: How an application is decided

Once an application has been submitted it will be examined to ensure that all the necessary information has been included and that it is properly signed and that the application fees have been paid. If so, the applicant will receive a letter of acknowledgment. If any of the basic information is not included, the applicant may be contacted for further information or the application and application fee may be returned with a letter describing the omission.

As soon as practicable after receiving an application for a facility licence, and once it has been determined to be complete, section 48 of the Regulations requires the CEO to publish a notice in a national daily newspaper and on the ARPANSA website, stating his intention to make a decision on the application. If the application relates to a nuclear installation, the CEO must 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.

Applications are then forwarded to a Regulatory Officer for assessment. Where matters require clarification, the Regulatory Officer will contact the applicant or nominee. The Regulatory Officer may also consider that an inspection or site visit is necessary and may contact the applicant to make arrangements.

Once the Regulatory Officer has reviewed and assessed all the information provided, a Regulatory Assessment Report (RAR) is produced. This report will address the matters to be taken into account by the CEO of ARPANSA in accordance with subsection 32(3) of the Act, namely international best practice in relation to radiation protection and nuclear safety and the matters specified in the Regulations. Division 5 of the Regulations specifies those matters. They are:

a) whether the application includes the information asked for by the CEO

b) whether the information establishes that the controlled apparatus or material can be dealt with without undue risk to the health and safety of people, and to the environment

c) whether the applicant has shown that there is a net benefit from the proposed conduct

d) 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

e) whether the applicant has shown a capacity for complying with the Regulations and the licence conditions that would be imposed under section 35 of the Act

f) whether the application has been signed by an office holder of the applicant, or a person authorised by an office holder of the applicant

g) In the case of a nuclear installation, the content of any submissions made by members of the public about the application.

The RAR will make a recommendation to the CEO (or delegate) about whether to issue a licence and may recommend the licence conditions to be imposed under section 35 of the Act. All relevant documentation is sent to the decision maker. The applicant will be advised in writing of the decision. The CEO (or delegate) will publish a ‘statement of reasons’ for the decision on the ARPANSA website.

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

Appendix 3: 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:

a) to refuse to grant a licence

b) to impose conditions on a licence

c) to suspend a licence

d) to cancel a licence

e) to amend a licence

f) not to approve the surrender of a licence

g) to issue a licence for a particular period, rather than for a longer period or indefinitely h) 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

If an applicant wishes 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.
Once a request for review has been 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.

1 Near-surface disposal facility; facilities established on or close to the surface.

2 Including, for example, storage and disposal of waste in a National Radioactive Waste Management Facility (NRWMF), should plans to establish a NRWMF currently under development by the Department of Industry, Innovation and Science be pursued.

3 See ARPANSA’s website www.arpansa.gov.au for guidance relevant to other types of radioactive waste than covered in this Regulatory Guide.

4 The term biosphere is often used in connection to the assessment of safety of facilities for storage and disposal of radioactive waste, meaning the part of the environment where organisms can be found.

5 A 2016 draft version of the Glossary is available from the IAEA website for informational purposes only: https://www-ns.iaea.org/downloads/standards/glossary/iaea-safety-glossary-draft-2016.pdf 

6 Radiation risk means detrimental health effects of exposure to ionising radiation including the likelihood of such effects occurring, and other risks including environmental risks, that might arise from exposure to ionising radiation; the presence of radioactive material (including radioactive waste) or its release to the environment; or a loss of control over a nuclear reactor core, nuclear chain reaction, radioactive source or any other source of radiation; alone or in combination (see RPS F-1, Fundamentals for Protection Against Ionising Radiation (2014)). 

7 Consultation required under section 48 of the Regulations, where the CEO is obliged to consult following receipt of a complete application. This will include publishing a notice in a national daily newspaper and on the ARPANSA website, stating their intention to make a decision on the application. The CEO must include in the notice: an invitation to people and bodies to make submissions about the application; a period for making submissions and procedures for making submissions [see Appendix 2]

8 See Section 5, Information for Stakeholders, page 31 of ICRP Publication 122.

9 Refer footnote 7.

10 An environmental impact assessment can be conducted in parallel with the licence application however a licensing decision will not be made until the EIS and its outcomes have been submitted to ARPANSA (see Section 2.1).

11 IAEA Safety Fundamentals SF-1 paragraph 3.19.

12 The effective dose is a risk-related quantity used for radiation protection purposes (not risk assessments) that integrates current knowledge of biological effectiveness of different types of radiations, and the likelihood of developing disease in different organs. It is measured in units with the special name sievert (Sv). For further specifics of radiation and tissue weighting factors, and other matters that relate to dosimetry and radiation risks, information in ICRP Publication 103 The 2007 Recommendations of the International Commission on Radiological Protection, Annals of the ICRP 37 (2-4) serves as the main reference.

13 A prudent approach could be to use reasonably cautious, yet realistic, assumptions in deterministic assessments; the use of overly pessimistic assumptions in successive iterations provides little information on actual safety performance and protective capability. In a probabilistic approach, a comprehensive analysis is made of failure scenarios to quantify risks. The applicant may chose the approach or a combination of approaches, but must provide justification for the chosen methodology and define the assumptions made.

14 The detriment adjusted nominal risk coefficient at low dose rates, applicable to the whole population and to stochastic effects (all cancers and heritable effects); of 5.7% per sievert given in Table 1 of ICRP Publication 103 must be used.

15 There is no risk-related quantity for radiation protection of organisms in the natural environment; hence the physical quantity absorbed dose is used. The absorbed dose is measured in units of joule per kg of absorbing matter, with the special name gray (Gy).

16 Refer footnote 7.

Regulatory Guide - How to seek an exemption from a licence (ARPANSA-GDE-1737)

Introduction

Section 30 of the Australian Radiation Protection and Nuclear Safety Act 1998 prohibits certain activities in relation to controlled facilities. Section 31 of the Act prohibits any dealing with controlled material or controlled apparatus unless the activity or dealing is authorised by a facility or source licence as appropriate, or is prescribed in Part 5 Division 2 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations) as exempt. 

Section 43 of the Regulations describes exemption of controlled persons from requirements for a facility licence for conduct relating to a controlled facility. This refers to Section 30(1)(g) of the Act.

Section 44 of the Regulations describes certain dealings with controlled apparatus and controlled material that are exempt. Schedule 1 Part 1 of the Regulations sets out exempt activity and activity concentration values for specific radionuclides. The Regulations do not prescribe any controlled facility as exempt.

In addition to the exemptions prescribed in the Regulations the CEO may also exempt from the need to be licensed those activities in relation to controlled facilities that require a licence under section 30 and those dealings with controlled material or controlled apparatus that require a licence under section 31.The CEO’s powers to exempt are derived from the following parts of the Regulations: 

  • Subsection 9(2) for apparatus that produces harmful non ionising radiation when energised prescribed under subsection 9(1) 
  • Subsection 13(2) for radiation facilities prescribed under subsection 13(1) 
  • Subsection 43(2) for one or more conducts specified in paragraph 30(1)(a), (b), (c), (d), (e) or (ea) of the Act in respect of a specified controlled person and in relation to a particular controlled facility
  • Subsection 44(3) for controlled material or controlled apparatus that produce ionising radiation 

The criteria that the CEO will use to determine if an exemption is to be granted and the matters that will be taken into account are explained below.  

1. Apparatus that produces harmful non ionising radiation when energised  

Subsection 9(1) of the Regulations prescribes those apparatus that produce harmful non-ionising radiation and which require a licence from ARPANSA under section 31 of the Act. However, under subsection 9(2) the CEO may declare in writing that a particular non-ionising radiation apparatus is not a controlled apparatus thereby removing the requirement for a licence.

Under subsection 9(3) the CEO must not make a declaration under subsection 9(2) unless the CEO is satisfied that:

(a) the apparatus does not pose an unacceptable hazard to the health and safety of people or to the environment; or

(b) it would be inappropriate for the apparatus to be a controlled apparatus.

A controlled person seeking a declaration under subsection 9(2) must provide sufficient evidence for the CEO to make a declaration that the apparatus meets the respective criteria under paragraphs (a) and (b) above in normal or routine conditions as well as under all reasonably foreseeable abnormal events or conditions.  

Note: Dealings with controlled apparatus that can produce non-ionising radiation that are prescribed in the table in subsection 44(1) are exempt. 

2. Prescribed radiation facilities 

Subsection 13(1) of the Regulations prescribes those facilities that are for the purposes of the Act ‘prescribed radiation facilities’ (PRFs). These controlled facilities require a licence for any of the conducts specified in paragraphs 30(1)(a), (b), (c), (d), (e) or (ea).  However under subsection 13(2) the CEO may declare in writing that a particular facility is not a PRF thereby removing the requirement for a licence.

Under subsection 13(3) the CEO must not make a declaration under subsection 13(2) unless the CEO is satisfied that:

a) the facility does not pose an unacceptable hazard to the health and safety of people or to the environment; and

b) it would be inappropriate for the facility to be a prescribed radiation facility.

A controlled person seeking a declaration under subsection 13(2) must provide sufficient evidence for the CEO to make a declaration that the facility meets the respective criteria under paragraphs (a) and (b) above in normal or routine conditions as well as under all reasonably foreseeable abnormal events or conditions.  

3. Conduct by a particular controlled person in relation to a particular controlled facility 

Subsection 43(2) of the Regulations provides the CEO the power to exempt any of the conducts mentioned in paragraph 30(1)(a), (b), (c), (d) (e) or (ea) of the Act by a particular controlled person in relation to a particular controlled facility (including any future conduct by the controlled person in relation to the controlled facility) provided the conduct does not or will not pose an unacceptable potential hazard to the health and safety of people or to the environment.

A controlled person seeking a declaration under subsection 43(2) must provide sufficient evidence for the CEO make a declaration that the conduct for which the exemption is sought will not pose an unacceptable potential hazard to the health and safety of people and the environment in normal or routine conditions as well as under all reasonably foreseeable abnormal events or conditions.

Note that unlike subsection 13(2), which gives the CEO the power to declare that a particular controlled facility is not a PRF (e.g. a portable neutron generator), subsection 43(2) gives the CEO the power to exempt a controlled person from the need to be licensed to undertake a particular conduct in relation to a particular controlled facility (e.g. decommission a linear accelerator).

4. Controlled material or controlled apparatus that produces ionising radiation

Dealing with a controlled apparatus or controlled material that can produce ionising radiation that is prescribed in section 44(1) is exempt. However, even if a controlled apparatus or controlled material is not listed in section 44(1), subsection 44(3) provides for the CEO to make a declaration under subsection 44(4) or 44(5) for certain low-dose or low-risk dealings, thereby exempting those controlled apparatus or controlled material. The CEO will only make such a declaration if satisfied of certain matters prescribed in the respective subsection. 

1. To seek an exemption under subsection 44(4) for a low-dose dealing, an applicant must make a written submission to the CEO and demonstrate that for the particular dealing for which an exemption is sought:

a) the annual effective dose to an individual during normal operations is not likely to exceed 10 μSv; or

b) an accident, misuse or exceptional circumstance affecting the dealing is not likely to produce an annual effective dose greater than 1 mSv.

Any submission for an exemption under paragraph 44(4)(a) should consider annual effective doses for:

  • normal use
  • accident scenarios
  • ultimate disposal scenarios
  • routine maintenance scenarios
  • source repair scenarios

To seek an exemption under subsection 44(5) in relation to one of the following:

a)    a radiological emergency or its after-effects

b)    the after-effects of a previous dealing

c)    naturally occurring material or bulk material with a mass more than 1000 kg

the applicant must make a written submission to the CEO and include an assessment of the magnitude of individual doses, the number of people exposed and the likelihood that potential exposure will actually occur justifies the dealing being exempt.

5. Regulatory assessment of a request 

ARPANSA will consider each application on its merits to determine whether the required statutory tests have been met. Decisions will be based on international best practice taking into account studies published by scientific and technology based organisations or other regulatory bodies. The implications of unregulated disposal will also be considered. 

6. Notice of intention to declare an exemption

If the CEO proposes to make a declaration of exemption under subsection 43(2) with respect to a controlled facility the CEO must publish the intention to do so in a daily national newspaper and on the ARPANSA website as soon as practicable. The notice must include either:  

a) a copy of the proposed declaration or

b) a description of the controlled person, the kind of conduct and the controlled facility that are to be the subject of the declaration and any conditions relevant to subsection 43(3). 

If the proposed declaration relates to a nuclear installation the CEO must issue an invitation for public submissions and provide information about the timing and procedures for making submissions.    

7. Publish a declaration of exemption

The CEO must publish a declaration under subsection 9(2), 13(2), 43(2), 44(2), 44(4) or 44(5) on ARPANSA’s website as soon as practicable after making it. 

8. Revoke a declaration of exemption

The CEO may revoke a declaration made under subsection 43(2) if the circumstances under which the controlled facility is owned, possessed or used has changed such that the controlled person can no longer satisfy the statutory tests on which the CEO’s earlier decision was made. 

9. Exception to exemption

Under subsection 44(2) the CEO may declare in writing that a particular dealing described in the table in subsection 44(1) has a risk of excessive dose and is therefore not exempted under subsection 44(1). This decision may be taken when:

(a) the annual effective dose to an individual during normal operations is likely to be greater than 10 μSv; or

(b) an accident, misuse or exceptional circumstance affecting the dealing is likely to produce an annual effective dose greater than 1 mSv.

10. Reviewable decision

A decision by the CEO to refuse to make a declaration under subsection 9(2), 13(2), 43(2) or 44(4) or 44(5) or to make a declaration under subsection 44(2) is reviewable under section 86 of the Regulations.

Regulatory Guide - When to seek approval to make a change with significant implications for safety (ARPANSA-GDE-1751)

 

Associated forms

1. Introduction

Section 63 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations) requires the holder of a licence to seek the CEO’s approval to make certain changes that will have significant implications for safety. 

If a change has significant implications for safety, the licence holder must seek approval to do either of the following: 
a)    change anything described in the application for the licence
b)    modify the controlled source, apparatus or facility described in the licence  

Examples of such changes can include: the alteration of processes; introduction or removal of equipment; modifications to structures, systems or components; changes in the way processes are undertaken or changes to the organisation; and changes to resourcing of a source or facility. 

ARPANSA considers that an implication for safety is a suggested or inferred effect on safety which, even if it is not easily derivable, possesses some degree of probability.  A significant implication is one which is important, notable, or of consequence, having regard to its context or intensity.  

In relation to this definition, this guide provides advice on when ARPANSA will consider that a change has significant implications. Where there is any doubt remaining on whether a change needs to be managed under section 63, applicants are encouraged to seek further advice from ARPANSA.
 

2. Document structure

This guide consists of four main sections. The first discusses ‘General Principles’ which must be considered when assessing the safety implications of a change. The second section provides a table of consequence thresholds above which ARPANSA will expect to receive an application for approval.  Sections 3 & 4 provide some practical examples of changes considered to fall under section 63 of the Regulations for both facilities and sources.

For guidance on the type of information ARPANSA needs licence holders to provide when requesting a change, please see the Submission Guide – Section 63 Request for Approval to Make a Change.

3. General principles 

ARPANSA’s approach to determine whether or not a change has a significant implication for safety is to consider the potential consequences of the proposed change, including an assessment of any credible consequence that may result if the proposed change is improperly conceived or executed. In broad terms these consequences may include a radiological impact on people or the environment, a loss of control of a source or facility, or a reduction in defence in depth[1].

To obtain a licence, the applicant was required to provide ARPANSA with plans and arrangements to demonstrate acceptable levels of safety and security.  The holder of a licence must comply with their plans and arrangements for managing safety.  Those aspects of the plans and arrangements that formed the basis for ARPANSA’s decision to grant a licence are called the ‘licensing basis’.  The licensing basis describes the controlled activity and establishes the boundary of activities within which safety is demonstrated.

Plans and arrangements describing how the licence holder maintains effective control, manages safety, provides radiation protection, deals with radioactive waste, manages security and prepares for and responds to emergencies will be part of the licensing basis. In the case of a facility, the safety analysis report (SAR), and the operating limits and conditions (OLCs) will also be key documents of the licensing basis. 

In general, proposed changes to a facility that are within the bounds of its approved licensing basis have already been approved by ARPANSA and are therefore unlikely to have significant implications for safety. However, the significance of any changes that could impact on the boundary established by the licensing basis should be assessed against the criteria of this guide.

In addition, if any of the following apply to the proposed change, it is likely to have a significant implication for safety (and therefore requires prior approval):

  • Results in more than a minimal increase in the likelihood or consequences of an accident or malfunction previously evaluated in the SAR.
  • Creates the possibility of an accident or malfunction of a different type from what was evaluated in the SAR.
  • Results in one or more radiological consequence as described in the SAR being increased.
  • Involves departure from a method of evaluation described in the SAR used in establishing the design or in the safety analysis.

It should be noted that reviews by the licence holder to determine the applicability of section 63 or 64 of the Regulations do not necessarily aim to determine if the proposed change is good or bad. The licence holder is expected to have other processes for determining if the proposed change is justified or warranted. The review focuses merely on whether prior approval by ARPANSA is required.

A cumulative effect of two or more relevant changes which individually do not have significant implications for safety must also be considered. This principle addresses the scenario where successive minor changes can, over time, lead to a significant change in the safety of controlled sources or facilities (organisational drift). Licence holders should be able to show that cumulative effects have been considered when making relevant changes.

 

4. Consequence thresholds for section 63 

The table below provides the thresholds above which ARPANSA considers a change to have significant implications for safety. In order to categorise changes, licence holders must have systems in place to evaluate the risk of certain changes. ARPANSA may ask licence holders to provide documentation to support their evaluation of a change considered unlikely to have significant implications for safety.

Note:  Appropriate review allows licence holders to know and manage the risks associated with their operation

Implication for safety

Threshold for section 63 

Radiological hazard outside of a controlled facility or building containing a source
  • Release activity at levels above discharge authorisations.
  • Release activity that may increase long term radiation levels off site to 20 µSv/yr or more (above background).
  • Release activity that may lead to a person being exposed to more than the annual dose limit to the public.

For further information on radiation limits refer to Regulations, Division 2 – Dose limits.

Exposure of people to radiation
  • Expose a member of the public to radiation in excess of the statutory annual limit (1 mSv).
  • Expose workers to radiation in excess of an annual dose limit.
  • Expose people to non-ionizing radiation at levels above appropriate exposure limits.

For further information on radiation limits refer to Regulations, Division 2 – Dose limits.

Impact on structures, systems or components important to safety
  • Cause failure or reduce the reliability or availability of any structure, system, or component that forms a primary means of ensuring radiation or nuclear safety, even where there is defence in depth remaining.
Impact on organisational controls or resourcing important to safety
  • Degrade safety management in a manner which removes organisational “checks and balances” for safety as described in the SAR or degrades defence in depth by failing to achieve adequate performance of staff in safety important roles.
To introduce or affect the likelihood or consequence of a dangerous occurrence
  • Increase the risk of operating outside of approved operating limits and conditions (where these are in place) or operational safety constraints.
  • Introduce a risk of an accident not previously considered, change consequences of an existing risk or affect the likelihood of a known risk.
  • Any change to an approved operating limit or condition (OLC) other than an editorial or typographical change. Note that the editorial or typographical change must NOT impact the safety case as presented in the Safety Analysis Report.
  • Any change that uses an alternative evaluation method from that relied on in the licence application or safety case.
Impact on the security of controlled facilities and apparatus
  • Potential to cause failure, or reduce the reliability or availability of a: system (including human systems); or structure or component that provides a primary protective security function (deterrence, detection, assessment, delay and response)—even where there are layers of defence remaining.
  • Potential to increase the threat level above that previously catered for by the protective security system and arrangements in place.

5. Examples of changes with significant implications for safety - facilities

The following examples of changes are provided for guidance only. It is important to relate any changes to the potential result of an unexpected outcome with a specific controlled facility. 

Proposed change

Implications for safety

Replacement of Safety Interlock System

Following a fault, it is necessary to replace a safety interlock system. The original interlock is no longer manufactured. The new device is different in fit, form or function.

The replacement interlock component offers improved maintainability and introduces new technology without changing the overall safety function of the system.

The interlock is described in the SAR and is a primary means of ensuring radiation safety. Poor implementation of the change has the potential to affect reliability or performance of the system.

Safety System Logic

It is found that instrumentation and control logic in the first of two independent safety systems does not meet its full safety function requirements. A modification of the control logic is necessary to correct the deficiency. 

 

The modification must, as described in the SAR, correct an error in the original system design or implementation. A modification of the control logic is planned. There is a potential for the change to fail to meet its required safety function or introduce a loss of function/reliability elsewhere if the change is poorly conceived or executed. Despite being one of two independent safety systems fulfilling essentially the same function, the potential risk of computer logic failure makes this a change with significant implications for safety based on the theoretical reduction in defence in depth level 3.

Increase Production of Radioisotopes

A licence holder wishes to increase the production rates by more frequent process runs in the existing facility. There is no need to change manufacturing methods.

An assessment of the change finds that the likelihood of an accident remains within the design basis authorised by the licence. However, increased processing may also increase the consequences of a design basis accident due to higher radionuclide inventory of the isotope and higher quantities of radioactive waste. The change therefore has significant implications for safety.

New radiation store

A licence holder plans to redesign and extend a radiation store to hold long-term radioactive waste and store radioactive materials. Existing controlled material will be centralised at the modified store.

The existing store is described in the SAR.

An assessment of the design and proposed management of the radiation store is necessary to ensure that it complies with relevant codes and standards. 

A poorly designed and managed radiation store has the potential to expose workers to radiation in excess of the annual dose limit and to release activity to the environment. 

Relocation of Radioactive Waste Store

For operational reasons it is decided to relocate a radioactive waste store.

During the course of relocation of radioactive materials to a new store, the potential exists for exposure and/or contamination of personnel and the environment. The SAR does not describe the movement of the store or its contents.

A risk assessment is undertaken which conservatively finds that damage to a container(s) during the movement may result in doses to workers at levels above the annual dose limits.

Changes to Working Hours

To improve customer service, it becomes necessary to alter worker shift rosters from an 8 hours working day (commencing at 9am) to a 12 hour working day (commencing at 6am). The average hours worked per week by staff will not be increased.

Assessment of the safety functions undertaken by workers shows that they are required to: operate controlled apparatus; maintain intended operational states; and detect and respond to process and equipment failures. Workers also have responsibility for emergency intervention and accident management.

Assessment of shift working indicates that disturbances to sleeping patterns can lead to fatigue. Fatigue is known to increase human error and accident rates by reducing alertness, slowing response time and impairing cogitative function.  Failure mode and effects analysis identifies that human errors could cause loss of control, exposure to workers and releases of radioactivity above threshold values.

The change is categorised as significant to safety on the basis that, if not properly managed, it may degrade the safety function/performance of staff in roles that are important to safety.

Organisational Restructure

A review of operational priorities and resourcing has resulted in a number of recommended efficiencies.

The changes include: a change to management structures, as described in the SAR, to decentralise quality assurance activities and better align the associated resources with scientific research; a change to the terms of reference for a number of management committees including the safety review committee; and a change to various financing initiatives.

A review and risk assessment of each individual change is undertaken.   This finds each to be a relevant change without significant implications for safety.

A review of the cumulative effect of the changes is also undertaken that compares the overall post change safety management practices with those in place at the time the licence was issued. The review finds that cumulatively checks and balances present when the licence was issued have been altered or removed and that safety and resource accountabilities have become blurred. Cumulatively it is assessed that the changes equate to being significant to safety as there is a possibility that staff performance may fail to meet required standards. 

 

6. Examples of changes with significant implications for safety - sources

The following examples of changes are provided for guidance only. It is important to relate any changes to the potential result of an unexpected outcome with a specific source.

Proposed change

Implications for safety

New radiation source store

A licence holder plans to redesign and extend a radiation store to hold long-term radioactive waste and store radioactive materials. Existing controlled material will be centralised at the modified store.

An assessment of the design and proposed management of the radiation store is necessary to ensure that it complies with relevant codes and standards. 

A poorly designed and managed radiation store has the potential to expose workers to radiation in excess of the annual dose limit and to release activity to the environment. 

Relocation of Radioactive Waste Store

For operational reasons it is decided to relocate a radioactive waste store.

During the course of relocation of radioactive materials to a new store, a potential exists for exposure and/or contamination of personnel and the environment. 

A risk assessment is undertaken which conservatively finds that damage to a container(s) during the movement may result in doses to workers at levels above the annual dose limit.

Class 4 laser used in the field

A licence holder plans to incorporate a Class 4 laser into an analyser which is to be used in the field in remote locations. The laser beam is not enclosed.  

The licence holder is currently licensed to deal with Class 4 lasers, with the original licence application relating to lasers used in the laboratory.

The laser will be used in a situation not assessed in the original application.

Unless the change is implemented with appropriate safety measures there is the potential to expose a person to levels above the appropriate exposure limit. 

Use of radioactive tracers

A licence holder is currently licensed to undertake tracer studies in the environment measuring C-14 uptake in plants.

The licence holder then wishes to undertake another environmental study which involved release of Tc‑99m tracer into a city harbour to study mixing current flows to establish how sewage outfall is being dispersed.

 

If inappropriately implemented, there is a potential for release of Tc-99m into the environment at concentrations such that the annual dose to a member of the public could exceed 1 mSv.  The previously approved safety assessment did not address release to city harbour.

ARPANSA was also consulted by the licence holder on the regulatory implications of an environmental study that investigated critical pathways, and assessed the impact of uptake by flora and fauna.  Advice was sought on the basis that the safety implications were notable (sensitive) even though under the threshold for environmental impact.


 

Organisational Restructure

A review of operational priorities and resourcing has resulted in a number of recommended efficiencies.

The changes include: a change to management structures, as described in the plans and arrangements, to decentralise quality assurance activities and better align the associated resources with scientific research; a change to the terms of reference for a number of management committees including the safety review committee; and a change to various financing initiatives.

A review and risk assessment of each individual change is undertaken.   This finds each to be a relevant change without significant implications for safety.

A review of the cumulative effect of the changes is also undertaken that compares the overall post change safety management practices with those in place at the time the licence was issued. The review finds that cumulatively checks and balances present when the licence was issued have been altered or removed and that safety and resource accountabilities have become blurred. Cumulatively it is assessed that the changes equate to being significant to safety as there is a possibility that staff performance may fail to meet required standards. 

[1] Defence in Depth is a commonly used practice of associating various safety barriers with different operational and accident states. The barriers can be physical or organisational and cover areas such as: design; maintaining intended operational states protection against accidents; and accident management and emergency off site response. Further information on defence in depth can be obtained from IAEA General Safety Requirements Part 3: Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards and IAEA General Safety Requirements Part 4: Safety Assessment for Facilities and Activities.

Regulatory Guide - Construction of an item important for safety (ARPANSA-GDE-1760)

Guidance for licence holders on the identification, classification, design and construction of items important to safety that require prior approval by the CEO of ARPANSA

Associated forms

1. Introduction

The holder of a licence, or a person covered by a licence, must have approval from the CEO of ARPANSA under section 66 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations) [1] to construct an item that is important for safety. The item must be identified in the safety analysis report as part of the construction of a controlled facility. 

Such an item may be a structure, system, or component (SSC) that contributes to managing safety in a facility. Often the detailed design information about a SSC is not fully available at the time of the application to construct the facility. Section 66 allows construction of the facility to be expedited without compromising safety by providing an application and approval process for items important to safety after the licence has been issued.       

This guide describes the process for the safety classification of SSCs for controlled facilities, and the design and construction criteria for such items. Items in safety categories 1-3 are subject to regulatory approval. 

2. International best practice

In accordance with Government policy, ARPANSA has adopted the ‘trusted international standard’ principle, under which additional requirements should not be imposed beyond international best practice, unless it can be demonstrated that there is a good reason to do so.

International best practice  

This regulatory guide is based on international standards published by the International Atomic Energy Agency (IAEA) specified as references [2], [3], [4], [5], & [7].

3. Purpose and scope

This document sets out the regulatory expectations for identifying and classifying items important to safety and provides guidance for the design and construction of such items in a manner that is commensurate with the safety analysis.

4. Classification of items important for safety

The IAEA provides the following definition of an item important for safety [2].

An item that is part of a safety group and/or whose malfunction or failure could lead to radiation exposure of the site personnel or members of the public. Items important to safety include:

  • Those structures, systems and components whose malfunction or failure could lead to undue radiation exposure of site personnel or members of the public;
  • Those structures, systems and components that prevent anticipated operational occurrences from leading to accident conditions;
  • Those features that are provided to mitigate the consequences of malfunction or failure of structures, systems and components.

The aim of safety classification is to identify and classify the items important for safety that were considered in the safety analysis report (SAR) for construction of the facility. These include SSCs that are required to protect the health and safety of people and the environment from harmful effects of radiation. The licence holder should consider the classification process described in this document in identifying and classifying the items important for safety in the SAR.

In classifying the structures, systems, or components, their main safety functions should be taken into account. As part of international best practice, ARPANSA adopts the requirements and recommendations of the International Atomic Energy Agency (IAEA) in its regulatory process. According to the IAEA requirements [3] for classification of structures, systems, or components, the requirements for fundamental safety functions1 are:

Requirements 4: Fundamental safety functions 

Fulfilment of the following fundamental safety functions for a nuclear power plant2 shall be ensured for all plant states: (i) control of reactivity, (ii) removal of heat from the reactor and from the fuel store and (iii) confinement of radioactive material, shielding against radiation and control of planned radioactive releases, as well as limitation of accidental radioactive releases.

A systematic approach should be considered in identifying items important for safety so that these items fulfil the main safety functions and inherent safety features contributing to fulfilling such functions for all plant states are taken into account. 

Further, the IAEA requirements for safety classification state:

Requirement 22: Safety classification

All items important to safety shall be identified and shall be classified on the basis of their function and their safety significance.

Classifying the items important for safety should be primarily based on deterministic methods, which will be complemented by probabilistic methods as appropriate. In classifying the items important for safety the following factors should be taken into account:

  • the safety function(s) to be performed by the item
  • the consequences of failure to perform a safety function
  • the frequency with which the item will be called upon to perform a safety function
  • the time following a postulated initiating event at which, or the period for which, the item will be called upon to perform a safety function.

5. Classification process

In classifying the items important for safety the functions of the SSCs considered in the design should be taken into account. Such functions may include primary functions and supporting functions that are expected to be performed to achieve the main safety function. These functions include those identified in the SAR at various levels of defence in depth, i.e. prevention, detection, control and mitigation safety functions.

The functions of the SSCs should be categorised on the basis of their safety significance taking into account the following factors:

  • the consequences of failure to perform the function
  • the frequency of occurrence of the postulated initiating event for which the function will be called upon
  • the significance of the contribution of the function in achieving either a controlled state or a safe state3.

For categorisation of functions of the SSCs, the licence holder is expected to use a categorisation system similar to that used by the IAEA [4] as such principles of categorisation of SSCs for nuclear installations are widely accepted. In terms of the safety significance in performing the safety functions of the SSCs the following three levels of severity of consequences are considered:

  • The severity should be considered ‘high’ if failure of the function could, at worst:
    • lead to a release of radioactive material that exceeds the limits considered in the design basis accidents; or
    • cause the values of key physical parameters to exceed acceptance criteria for design basis accidents as they relate to the design limits for the items important for safety and the set of accident conditions derived from postulated initiating events for establishing boundary conditions in the design basis accidents
  • The severity should be considered ‘medium’ if failure of the function could, at worst:
    • lead to a release of radioactive material that exceeds limits established for anticipated operational occurrences; or
    • cause the values of key physical parameters to exceed the design limits for anticipated operational occurrences
  • The severity should be considered ‘low’ if failure of the function could, at worst:
    • lead to doses to workers above the authorised limits

In order to adopt a conservative approach in categorisation of functions, the highest of the three levels should be applied when more than one of the above three definitions is met. In assessing the consequences it should be assumed that function does not respond when challenged.

For anticipated operational occurrences, the assessment of the consequences should assume that all other independent functions are performed correctly. 
In terms of safety functions the following safety categories are recommended by the IAEA [4].

Safety Category 1

Any function that is required to reach the controlled state after an anticipated operational occurrence or a design basis accident and whose failure, when challenged, would result in consequences of ‘high’ severity.

Safety Category 2

  • Any function that is required to reach a controlled state after an anticipated operational occurrence or a design basis accident and whose failure, when challenged, would result in consequences of ‘medium’ severity; or
  • Any function that is required to reach and maintain for a long time a safe state and whose failure, when challenged, would result in consequences of ‘high’ severity; or
  • Any function that is designed to provide a backup of a function categorized in safety category 1 and that is required to control design extension conditions without core melt (for a reactor).

Safety Category 3

  • Any function that is actuated in the event of an anticipated operational occurrence or design basis accident and whose failure, when challenged, would result in consequences of ‘low’ severity; or
  • Any function that is required to reach and maintain for a long time a safe state and whose failure, when challenged, would result in consequences of ‘medium’ severity; or
  • Any function that is required to mitigate the consequences of design extension conditions, unless already required to be categorized in safety category 2, and whose failure, when challenged, would result in consequences of ‘high’ severity; or
  • Any function that is designed to reduce the actuation frequency of the reactor trip or engineered safety features in the event of a deviation from normal operation, including those designed to maintain the main plant parameters within the normal range of operation of the plant; or
  • Any function relating to the monitoring needed to provide plant staff and off-site emergency services with a sufficient set of reliable information in the event of an accident (design basis accident or design extension conditions), including monitoring and communication means as part of the emergency response plan (defence in depth level 5), unless already assigned to a higher category.

If the function of the system is considered to be in more than one category, the highest category should be assigned to this category. This is due to the fact that the function is needed for more than one postulated initiating event. The following table summarises the categorisation in terms of the functions in postulated events [4].

Table 1. Relationships between functions credited in the analysis of postulated initiating events and safety categories
Functions credited in the safety assessmentSeverity of the consequences if the function is not performed
HighMediumLow
Functions to reach a controlled state after anticipated operational occurrencesSafety category 1Safety category 2Safety category 3
Functions to reach a controlled state after design basis accidentsSafety category 1Safety category 2Safety category 3
Functions to reach and maintain a safe stateSafety category 2Safety category 3Safety category 3
Functions for the mitigation of consequences of design extension conditions4Safety category 2 or 3Not categorised*Not categorised*

* Medium or low severity consequences are not expected to occur in the event of non-response of a dedicated function for the mitigation of design extension conditions

NOTE: The categorisation of safety functions should not take account of any redundancy, diversity or independence within the design as these aspects relate to the structures, systems and components that deliver the safety functions. 

The categorisation assigned to each safety function should be used to classify the SSCs that deliver the function.

Following the categorisation of the safety functions, the SSCs should be assigned to a safety class in accordance with the functions. The SSCs implemented as design provisions should be identified and classified using the same criteria as those used for the classification of SSCs needed to perform safety functions.

Based on the design of the facility/plant, the design provisions can be directly classified into the following three categories in terms of severity of consequences of their failure:

  • Safety class 1: Any SSC whose failure would lead to consequences of ‘high’ severity
  • Safety class 2: Any SSC whose failure would lead to consequences of ‘medium’ severity    
  • Safety class 3: Any SSC whose failure would lead to consequences of ‘low’ severity

Note: Design provisions can be directly classified because the significance of SSC’s postulated failure fully defines its safety class without any need for detailed analysis of the category of the associated safety function.

Where a SSC performs several functions of different categories, the highest class should be assigned to that SSC.

If the safety class of the connecting or interacting SSCs is not the same, a device of higher safety class should be used for interface to ensure that there will be no effects from a failure of the SSC of the lower safety class.

Once the safety class is assigned to each SSC, suitable engineering principles and criteria should be applied for design and construction of the SSC to achieve an appropriate level of quality and reliability. 

In applying classification, and design principles and criteria a graded approach should be used as necessary in accordance with the importance of the SSC. The IAEA provides a useful guidance on use of a graded approach in relation to research reactors [5].

6. Design principles and criteria

As part of international best practice the widely accepted fundamental principle is defence in depth. Defence in depth is used to provide a high degree of confidence that accidents in facilities will be prevented, and to ensure that the radiological consequences of any design-basis accidents would be minor and within prescribed limits. Furthermore, defence in depth is used to ensure that the likelihood of any beyond-design-basis accident that could have serious radiological consequences is extremely small.

Defence in depth is implemented in the form of a hierarchy of diverse levels of equipment and procedures. The implementation of defence in depth in the design of a facility provides a graded protection against a wide variety of operational occurrences and accidents, including those that might originate from equipment failures and human error, and events that initiate outside the facility. When properly implemented, the principle should ensure that no single human or equipment failure would lead to injury to the public, and unlikely combinations of failures would lead to little or no injury.

Defence in depth affords substantial protection against common cause failures, including performance failures. Performance failures are the class of common cause failures that occur when a system important to safety functions when required (that is, no components fail), but it functions in a way that does not provide the intended protection.

Further details on defence in depth with emphasis on design aspects are described in ARPANSA’s regulatory assessment criteria [6] and in the IAEA INSAG Report [7]. 

Items important to safety are used at all defence in depth levels. Therefore, these items need to be designed and constructed to a standard and quality that is commensurate with their categorisation by safety significance applying appropriate principles and criteria.
The following principles and criteria are used in assessing the design and construction of an item important for safety. At the time of assessment, ARPANSA considers the relevance of each principle and criterion to allow for different types of controlled facility, controlled apparatus or controlled material. ARPANSA may assess some principles and criteria as being not relevant because they do not apply to the particular controlled facility, controlled apparatus or controlled material being assessed. Any principles and criteria relevant to the particular controlled facility, controlled apparatus or controlled material that involve radiation dose limits are regarded as mandatory.

6.1. Conservative proven design and engineering practice

Conservative design, with safety margins, applies at defence in depth levels 1 through 3. Design of structures systems and components with safety functions at these levels of in depth should adopt a conservative approach, and proven technology should be used so that the safety function is performed at an appropriate level.

1. Conservative, proven design and engineering practice should be used for design of items important for safety at defence in depth levels 1-3. At levels 4 and 5 best estimate methodologies should be used.

2. The design establishes conservative operational limits and conditions that allow for engineered tolerance and margins of error. Those limits thus provide safety margins for each operational state and for accident conditions that are based on the safety analysis. Items important to safety should be designed in a manner that is commensurate with the safety analysis.

3. Conservatism should be used in the specification of materials used for pressure retaining structures and components to afford protection against brittle fracture.

4. Feedback from design and operational experience should be taken into account in the design, including feedback of experience from safety system performance testing, maintenance, and the analysis of incidents and safety performance of similar facilities worldwide. 

5. Technologies incorporated in the design should be proven technologies, developed through: innovation, laboratory scale demonstrations, operating prototypes, and use in other facilities.

6. Proven engineering practice and standards should be used in design, manufacture, and construction and commissioning of items important for safety.

6.2. Codes and standards

Appropriate codes and standards should be applied to the design, manufacturing, construction, installation, commissioning, quality assurance, testing and inspection of structures, systems and components that are important to safety.

7. The codes and standards applied should reflect the functional reliability requirements of the structures, systems and components and be commensurate with their safety classification. 

8. Nuclear-specific standards and codes should be used as available, leading to a conservative design commensurate with the importance of the safety function(s) being delivered. Each code or standard adopted should be evaluated to determine its applicability, adequacy and sufficiency and should be supplemented or modified as necessary to a level commensurate with the importance of the relevant safety function(s).

9. Appropriate nuclear industry-specific, national or international codes and standards should be adopted for Safety Class 1 and 2 structures, systems or components. For Safety Class 3, if there is no appropriate nuclear industry-specific code or standard, an appropriate non-nuclear-specific code or standard should be applied instead.

10. Where a single item (i.e. a structure, system or component) needs to deliver multiple safety functions, and these can be demonstrated to be delivered by the item independently of one another, then separate codes and standards should be used appropriate to the parts of the item providing each safety function. Where such independence cannot be demonstrated, codes and standards should be appropriate to the class of the item (i.e. in accordance with the highest category of safety function to be delivered). Whenever different codes and standards are used for different aspects of the same item, the compatibility between these codes and standards should be demonstrated.

11. If different design codes and standards are used for different parts or aspects of the same item that is important to safety, the consistency between them should be demonstrated. 

12. For items important to safety for which there are no appropriate established standards or codes, an approach derived from existing standards or codes for similar items should be applied, or in the absence of such codes and standards, the results of operational experience, tests and analysis should be applied and justified.

13. The safety item designed according to engineering design codes and standards that are already established in another country or are used internationally, and for which use is justified and also judged as acceptable by ARPANSA.

14. Any fabrication and construction processes should follow the codes and standards that are specific to the country in which the facility will be constructed.

15. Where computer-based systems are used in items important to safety: 

  • Appropriate standards and practices should be applied in the development, validation, and testing for verification of performance of the hardware and software at each phase of their development.
  • The level of reliability assumed in the design of computer-based systems should be conservative unless it can be shown that there is sufficient test and check data from the operational performance of identical elements used in similar applications.

6.3. Redundancy, independence and diversity 

Uncertainties and the susceptibility of structures, systems and components to common cause failures can be reduced by the provision of physical and functional independence and diversity between the levels of defence in depth.    

16. Independence and diversity should be provided between levels of defence in depth.

17. Safety systems must have sufficient redundancy so that no single fault can lead to failure of the system, including during testing and maintenance and during shutdowns, when safety systems may be degraded. 

18. The design of systems important to safety should be subject to safety analyses to determine the required extent of redundancy.

19. The highest degree of physical and functional independence and diversity should be used in redundant systems where the safety significance is highest.

20. Redundant subsystems in safety systems are to be kept functionally and physically separate, from measurement of the process variable (avoiding common sensors) through to shutdown actuation.

21. Diversity should be used in redundant safety systems, from measurement of the process variable through to shutdown actuation. 

22. Items important to safety, including items as different as buildings, pumps, water supply systems, process plant, and software, are designed such that their quality and reliability is commensurate with their categorisation by safety significance.

23. The design of items important to safety should address sensitivities to the assumptions made, the data used, and the methods of calculation. Where the design is sensitive to the modelling assumptions, they are supported as far as practicable by additional analyses using independent methods or by experiments and tests.

24. Items important to safety should be designed and qualified to accommodate the effects of the environmental conditions associated with operational states and design- basis accidents (including loss-of-coolant accidents). In the case of design-basis accidents, the environmental conditions are those that would prevail if the items were required to function. The environmental conditions include vibration, temperature, pressure, jet impingement, electromagnetic interference, radiation, and humidity that may exist at the time of need.

25. Safety systems should be distinguished by clear markings (for example, colour codes or fixed notices) so that they stand out in contrast to systems that are not important to safety.

26. Safety systems additionally must be distinguished from safety-related systems by clear markings to emphasise their different categorisations by safety significance. 

6.4. Reliability

There should be due consideration of inherent safety features in design of the structures, systems and components.

27. There should not be unsafe failure modes in the structures, systems and components or they should be failsafe.

6.5. Validation and verification

An appropriate program of design verification and validation should be in place that confirms that the design is adequate and in accordance with the design specifications.

28. The program of design verification should include a review of the design of items important to safety, particularly for new design features where special attention is given to potential new failure modes and performance. The review should establish that all required inspections, examinations and tests of items important to safety can be performed throughout the lifetime of the facility.

29. The program of design verification should address environmental and seismic testing to confirm structure, system and component capability as relevant.

30. Computer modelling programs that are used in the design of items important to safety should be verified and validated, addressing:

  • The use of internationally accepted benchmark calculations.
  • The limitations of the programs and the specific conditions for which they are being applied.
  • Support for their results from experimental measurements and irradiation experience.
  • The formal reporting mechanism that is used if output from the programs that has been used in the design process is found to be invalid.

6.6. Testing, inspection and maintenance

Items important for safety should be designed and constructed in such a way that they can be tested, inspected and maintained before operation and throughout the operational lifetime of the facility to assure that the intended design objectives are achieved and any deficiencies are identified and dealt with appropriately to prevent common cause failures.

31. There should be a plan and program for testing, inspection and maintenance for the items important for safety.

32. Where the testing, inspection or maintenance of a safety system requires a change in the configuration appropriate arrangements should be in place for monitoring of such changes and restoration of those changes and for compensating for the temporary unavailability of the items being tested/inspected/maintained.  

6.7. Ageing and degradation

The design of structures, systems and components important for safety should take into account the effective management of ageing so that the safety functions are delivered throughout the period needed. The ageing and degradation management of SSCs should be based on international best practice such as IAEA Safety Standards Ageing Management for Research Reactors, Specific Safety Guide, No. SSG-10, IAEA, Vienna, 2010 

33. There should be design conservatism for items important to safety regarding ageing and wear-out mechanisms. Allowance should be made for age-related degradation caused for example by vibration, irradiation and thermal cycling.

34. An appropriate program or arrangement should be in place for ageing management for the SSCs. Such program may include monitoring, inspection, maintenance and testing to monitor ageing and degradation processes.

35. An adequate margin should be considered between the intended operational life and predicted safe working life of the items important for safety.

36. A process should be in place to review the obsolescence of structures, systems and components important to safety.

6.8. Quality Assurance

The QA program addresses the design of all structures, systems and components that are important to safety at all defence in depth levels, including process control systems, safety systems, and modifications. Each level of defence in depth can be effective only if the quality of the design can be relied on.

37. The QA program should be applied to items important to safety to an extent that is commensurate with their categorisation by safety significance, so that the quality of the design is ensured at all times. For each item, the QA program addresses: 

  • Design testing to verify performance under operational state and design-basis accident conditions.
  • The incorporation in the design of feedback from operational experience from similar designs, as relevant.
  • The design basis for:
    • Periodic inspection and testing frequencies and procedures
    • Maintenance program
    • Means of verifying performance
    • Periodic safety reviews and their frequency

38. Where an item important to safety is computer-based, the QA program should address: 

  • Safety performance and how that is achieved through the use of properly qualified hardware and software
  • Verification of its performance
  • Independent safety assessment by qualified personnel
  • Documentation that permits a review of the item's whole design process, including testing for verification of performance and commissioning

Plant layout and access

The design and layout should consider the access requirements to the structures, systems and components that contribute to the significant safety function in operating the facility, and the movement of equipment above the items important for safety.

39. The layout should take into account the factors that can affect ease of access to the item important for safety for operational needs.

40. The layout should consider the aspects of construction, installation, testing, maintenance and inspection.

41. Where possible the layout should minimise the lifting of loads and movement of equipment above the items important for safety.

3 Controlled state: Plant state, following an anticipated operational occurrence or accident conditions, in which the fundamental safety functions can be ensured and which can be maintained for a time sufficient to implement provisions to reach a safe state.
Safe state: Plant state, following an anticipated operational occurrence or accident conditions, [in which the reactor is subcritical (for a nuclear power plant and/or a research reactor)] and the fundamental safety functions can be ensured and maintained stable for a long time.

4 Accidents conditions that are not considered for design basis accidents, but that are considered in the design process of the facility in accordance with best estimate methodology, and for which releases of radioactive material are kept within acceptable limits. Design extension conditions could include severe accident conditions.
