Application of Generic PRA (Probabilistic Risk Assessment) Insights to NRC (Nuclear Regulatory Commission) Inspection

摘要

The United States Nuclear Regulatory Commission (NRC) has developed a program that uses probabilistic risk assessment (PRA) results to produce plant specific inspection guidelines for use by NRC inspectors. Because only about one-quarter of the operating United States (US) plants have PRAs, a generic methodology has been proposed for the production of inspection guidelines for plants without PRAs. The first application of this proposed generic method was to a plant which has a PRA, so a comparison of the inspection guidance produced by the PRA-based and generic methods could be made. An evaluation of the comparison from that application is provided. (ERA citation 13:029079)
