Similarly, the NRC staff will also employ risk insights and PSAs in evaluating Technical Specifications related submittals. Further, as a part of the Commission's ongoing program of improving Technical Specifications, it will continue to consider methods to make better use of risk and reliability information for defining future generic Technical Specification requirements. The Commission reiterated this point in July 1995 when it issued the revision to 10 CFR 50.36 (Reference 11). In August 1995, the NRC adopted the policy statement, including the following, for the expanded use of PRA (Reference 1). 16.1-3 Revision 1 - March 2007 1.

PRA and associated analyses (e.g., sensitivity studies, uncertainty analyses, and importance measures) should be used in regulatory matters, where practical within the bounds of the state of the art, to reduce unnecessary conservatism in current regulatory requirements, RGs, license commitments, and staff practices. Where appropriate, PRA should support the proposal of additional regulatory requirements in accordance with 10 CFR 50.109 (Backfit Rule) (Reference 12).
