review process. With respect to PRA quality, the following items are noted: A. There are no regulatory requirements in 10 CFR Part 52 that specifically pertain to PRA quality with respect to DC or COL applications. B. RG 1.206 and this SRP section indicate the expected scope and level of detail of a PRA used to support a DC or COL application. Exceptions to this expected scope and level of detail may be acceptable if adequately justified by the applicant. 11. The PRAs that meet the applicable supporting requirements for Capability Category I and meet the high-level requirements as defined in the ASME PRA Standard (ASME/ANS RA-S-2008 and addenda ASME/ANS RA-Sa–2009) should generally be acceptable for DC and COL applications. Alternatively, the applicant may identify, and justify the acceptability of, alternative measures for addressing PRA quality and technical adequacy. The staff should specifically review the acceptability of these alternative measures in the context of the specific uses and applications of the PRA. 12. In making its determination of technical adequacy of the PRA, the staff will consider the information provided by applicants in FSAR Chapter 19 and responses to the staff's RAIs or obtained by the staff during onsite audits. In addressing the technical adequacy of the PRA, the applicant should discuss: A. Prior NRC staff review of the PRA (e.g., during the DC process), findings (i.e., facts and observations) from that review, disposition of those findings, and 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
