and makeup of the review team, etc.). Results from previous staff reviews of the PRA (e.g., from previous applications) could also provide a good starting point. In cases where the PRA is based on the individual plant examination (IPE) or the IPE of externally 19.2-17 June 2007 initiated events (IPEEE) models, reviewers should also be familiar with the request for additional information (RAI) issued by the staff in connection with those examinations, as well as the licensee’s responses to those RAIs, and the staff evaluation reports regarding the licensee’s IPE and IPEEE submittals. Reviewers could reach a finding that previous industry reviews, with or without licensee self assessments, or staff reviews are sufficient to show that the PRA is of adequate quality in one or more of the review areas for the present application. In such cases, the scope of the review should be adjusted accordingly. However, reviewers should be aware of potential application-specific differences and of the currency of the previous review findings with respect to the current plant design and operating procedures. It should be noted that the NRC has not developed its own formal standards. However, the NRC continues to support ongoing initiatives to develop such standards and endorses standards that are suitable for regulatory decisionmaking in Regulatory Guide 1.200. III.2.2.4.2 Quality Assurance Requirements Related to the PRA To the extent that a licensee elects to use PRA as an element to enhance or modify its implementation of activities affecting the safety-related functions of SSCs, appropriate quality requirements will also apply to the PRA. In this context, therefore, a licensee would be expected to control PRA activity in a manner commensurate with its impact on the facility’s design and licensing basis. Regulatory Guide 1.174, Section 2.5 describes the quality elements that apply to the licensee’s PRA activities. Reviewers should verify that the quality of analyses and
