f risk and reliability information for defining future generic Technical Specification requirements. I The improved Standard Technical Specifications (NUREGs 1430-1434) (Refs. 3-7) use the terminology "Completion Times" and "Surveillance Frequency" in place of 'Allowed Outage Time" and Surveillance Test Interval". Rev. 0 - August 1998 SRP 16.1-2 The Commission reiterated this point when it issued the revision to 10 CFR 50.36 in July 1995 (Ref. I 1). In August 1995, the NRC adopted the policy statement, including the following, regarding the expanded use of PRA (Ref. 1). * The use of PRA technology should be increased in all regulatory matters to the extent supported by the state of the art in PRA methods and data and in a manner that complements the NRC's deterministic approach and supports the NRC's traditional defense-in-depth philosophy. * 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 associated with current regulatory requirements, regulatory guides, license commitments, and staff practices. Where appropriate, PRA should be used to support the proposal of additional regulatory requirements in accordance with 10 CFR 50.109 (Backfit Rule) (Ref. 12). Appropriate procedures for including PRA in the process for changing regulatory requirements should be developed and followed. It is, of course, understood that the intent of this policy is that existing rules and regulations shall be complied with unless these rules and regulations are revised. * PRA evaluations in support of regulatory decisions should be as realistic as practicable and appropriate supporting data should be publicly available for review. * The Commission's safety goals for nuclear power plants and subsidiary numerical objectives are to be used with appropriate consideration of uncertainties in making regulatory
