    Abstract

    The overall objective of the PURISTA project was to support the implementation of risk-informed in-service inspection (RI-ISI) at Finnish nuclear power plants by studying relevant issues related to RI-ISI. Main objectives were the development of structural reliability methods for quantification of piping leak and break probabilities, the development of methods for evaluating inspection capability and the link between inspection qualification, detection probability and RI-ISI, and studying issues related to risk-ranking, selection of inspection sites and acceptance criteria of a RI-ISI programme. The project has contributed to several international activities, including the participation in the work of the Task Group on Risk (TGR) of the European Network for inspection and Qualification (ENIQ).
