Prioritization of Components Important for Safety and Sensitive to Ageing - Application for TRIGA Reactor

Due to potential impact on the SSC performances, the identification of ageing effects and implementation of appropriate methods for mitigation of these effects becomes in the last years an important preoccupation of many organizations and research activities. The efforts deployed for developing time-dependent reliability models for all SSC may be considerable and may outweigh the benefits, but are not always necessary, mainly because in some cases, the maintenance, test, inspection and surveillance methods are good provision to mitigate the ageing effects. To efficiently use the limited resources, it is necessary to identify and prioritize the SSC that need time-dependent reliability models using specific criteria. This paper contributes to the effort of performing an efficient process of ageing effects evaluation, using probabilistic safety assessment models. The paper presents the approach developed for SSC selection, and the results obtained for two particular systems of TRIGA research reactor.
