ot be used directly to assess whether the PRA was in conformance with the ASME standard. 3 On August 16, 2002, NEI submitted draft industry guidance for self-assessments (Ref. 5) to address the use of industry peer review results in demonstrating conformance with the ASME PRA standard. This additional guidance contains: 1. Self-assessment guidance document 2. Appendix 1, actions for industry self assessment 3. Appendix 2, industry peer review subtier criteria. Concerns regarding PRA quality and the standards development effort were discussed during the March 31, 2000, Commission briefing on the Risk-Informed Regulation Implementation Plan. The Commission, in their April 18, 2000, Staff Requirements Memorandum (SRM) (Ref. 6) on that briefing, indicated that the staff “should provide its recommendations to the Commission for addressing the issue of PRA quality until the ASME and ANS standards have been completed, including the potential role of an industry PRA certification process.” In response to the Commission’s SRM dated April 18, 2000, the staff issued SECY-00-162, “Addressing PRA Quality in Risk-Informed Activities” (Ref. 7), which described an approach for addressing PRA quality, including identification of the scope and minimal functional attributes necessary to ensure that the PRA information is adequate for its intended application in decision making. The Commission, in their October 27, 2000, SRM, indicated that the “. . . the timely resolution of PRA quality requirements is necessary to support existing and developing risk-informed regulation . . . .” (Ref. 8). In response to that SRM,, Regulatory Guide 1.200 (Ref. 9) was issued for trial use in February 2004. This provided the staff’s position on Addendum A of the ASME Standard, and on the NEI peer review process, including the self-assessment guidance. On May 19, 2006, NEI issued a revision to the self-assessment guidance and incorporated it in NEI-00-02, to satisfy the peer review
