dc.description.abstractWhen granting the Facility Licence, Operating Authorisation for the OPAL reactor, the Australian nuclear regulator ARPANSA imposed a licence condition that a periodic safety review (PSR) should be performed at least once every 10 years, with the first to be completed within 2 years of the completion of commissioning. This first PSR has recently been completed and this paper focusses on the review of the deterministic safety assessment and specifically the application of a fault schedule to: 1. Assess the scope and extent of postulated initiating events considered in the deterministic safety assessment. 2. Determine the adequacy of the levels of defence in depth provided for postulated initiating events. 3. Identify any shortcomings in either of the above. ln addition, it is ANSTO‘s intent to revise the existing deterministic safety analysis to incorporate the fault schedule and this paper describes this process and discusses the benefits that are anticipated to result from it. For example, it is expected that a fault schedule will facilitate operations and support staff interrogating and understanding the deterministic safety assessment. The paper also outlines the methodology by which the fault schedule was developed and provides guidance to those who may wish to apply the same methodology to their own nuclear facility.en_AU
