NRRC Risk-Informed Decision Making Workshop Report

 Toward the continuous improvement of nuclear safety, Nuclear Risk Research Center conducts not only R&Ds for the implementation and further development of PRA (Probabilistic Risk Assessment) but also promotional activities for application of the risk information in the operational management of nuclear power plants.

 We conducted a research on the implementation experience of Risk-Informed Decision Making (RIDM) in the United States supported by experienced experts in the US from both industry and regulation and then published a report as part of the effort.

*The report is available from the link below.

 We also organized a workshop inviting the US experts contributing to the report. Through this workshop, NRRC expected that key players in Japan deepened understanding of the experience and lessons learned in the US and obtain specific insights toward the proper application of RIDM in Japan.
