Faulting on Replacement Research Reactor Site
During the preparation of the site for the RRR, a geological fault was discovered in May 2001. Subsequent action was requested of ANSTO by the CEO to ensure that the safety of the project would not be undermined. These actions, along with the CEO’s assessment, are listed below.

Reactor Pool Liner Repair
In May of 2003,the CEO of ARPANSA, Dr John Loy, was advised by ANSTO that errors had been made in the fabrication of the reactor pool liner for the RRR and unauthorised repairs had been conducted. An extensive investigation was conducted by ARPANSA staff into the matter.
As a result of these investigations, the CEO ANSTO's repair strategy in relation to errors made during fabrication of the stainless steel pool liner, or tank, for the replacement research reactor at Lucas Heights in Sydney's south. As an outcome of his review of the errors, he also intends to apply three new licence conditions on the reactor construction licence issued to ANSTO in April 2002.
