The Application of Risk-Informed-Inservice Inspection to Recirculation Piping Welds of a Nuclear Power Plant

摘要

The implementations of RI-ISI can improve the substantial cost reductions as well as dose reduction. From the points of the safety concern, the achievements of these procedures can identify the inspection rank to promote the integrity of the present inspection program. Thus, this paper presents the applications of RI-ISI to recirculation piping welds sensitized to IGSCC of Taiwan BWR-4 nuclear power plant. The establishment of the risk evaluation can be referenced for the regulatory and plant maintenance.
