片桐 康寛 Yasuhiro KATAGIRI Abstract: This paper discusses a PSA approach to evaluate the economic risk importance of Balance Of Plant (BOP) system equipment/component with respect to loss of power production, that is the plant trip or the plant power reduction. The economic risk importance used in this study is the Megawatt-Hour loss. Knowing this relative import ance of the BOP system equipment/components allow the plant to prioritize the maintenance of the equipment. This study was performed on a typical ...

Application of the Economical Risk Information for the Maintenance Activity Using PSA Approach

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....
