概要
The feasibility study of RI-ISI (Risk-Informed In-Service Inspection) has been carried out based on 2-loop PWR as the pilot pl ant. The knowledge about failure potential derived from “Whole Maintenance Program for Piping” and results of PSA were combined in this work. The risk matrix of EPRI was referred to when the importance of piping segments was classified. It turns out that RI-ISI could reduce the number of welds required for inspection by present way, while the risk level remains at the same level.
