    The overall objective of the PURISTA project is 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 are 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 includes several international activities, the most important being the participation in the European Network for inspection and Qualification (ENIQ), especially in the work of its Task Group on Risk (TGR).
