INTRODUCTION The NRC's policy statement on probabilistic risk analysis (PRA)(Ref. 1) encourages greater use of this analysis technique to improve safety decisionmaking and improve regulatory efficiency. The NRC staffs PRA Implementation Plan (Ref. 2) describes activities now under way or planned to expand this use. One activity under way in response to the policy statement is the use of PRA in support of decisions to modify an individual plant's technical specifications (TS). Licensee-initiated TS changes that are consistent with currently approved staff positions [e.g., regulatory guides, standard review plans, branch technical positions, or the Standard Technical Specifications (STS) (Refs. 3-7)] are normally evaluated by the staff using traditional engineering analyses. A licensee would not be expected to submit risk information in support of the proposed change. Licensee-initiated TS change requests that go beyond current staff positions may be evaluated by the staff using traditional engineering analyses as well as the risk- informed approach set forth in Regulatory Guide 1. 177, "An Approach for Plant-Specific Risk- Informed Decisionanaking: Technical Specifications" (Ref. 8). A licensee may be requested to submit supplemental risk information if such information is not provided in the original submittal by the licensee. If risk information on the proposed TS change is not provided to the staff, the staff will review the information provided by the licensee to determine whether the application can be approved based upon the information provided using traditional methods and will either approve or reject the application based upon the review. Rev. 0 - August 1998 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants.
