ghts, the staff should conduct an audit of the applicant’s/holder’s PRA against the technical elements described in RG 1.200, “An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk- Informed Activities,” to determine the PRA technical adequacy. 19.0-14 Revision 3 – December 2015 the relevance of that review to the technical adequacy of the current plant- specific PRA. B. The scope, level of detail, and technical adequacy needed to support the specific uses and risk-informed applications. C. The method used for determination of technical adequacy for pertinent PRA scope areas for which the NRC has not endorsed PRA standards (i.e., identify the guidance and good practices documents relied upon to determine the technical adequacy of the PRA). D. The independent peer review process, including the qualifications of the team members and the findings identified as a result of the review. E. The process for dispositioning independent peer review findings and maintaining or upgrading the PRA, as appropriate, to ensure that it reasonably reflects the as-designed, as-built, and as-operated plant, including the corrective action and feedback mechanisms involving the periodic evaluation of the PRA, consistent with its uses and risk-informed applications, on the basis of actual plant-specific equipment, train, and system performance and relevant industry operational experience. 13. The staff will determine whether the assumptions made in the applicant’s PRA during design development and certification, in which a specific site may not have been identified or all aspects of the design (e.g., balance of plant) may not have been fully developed, are identified in the DC application and either remain valid or are adequately addressed within the COL application. 14. The staff will determine whether FSAR Chapter 19 includes PRA quantitative and qualitative results, including CDF, LRF, the identification of key PRA assumptions,
