2015 C. Documentation and maintenance of records, including archival documentation as well as submittal documentation D. Use of procedures that ensure that appropriate attention and corrective actions are taken if assumptions, analyses, or information used previously are changed or determined to be in error 10. The staff will determine whether the technical adequacy of the PRA is sufficient to justify the specific results and risk insights that are used to support the DC or COL application. Toward this end, the applicant’s PRA submittal should be consistent with prevailing PRA standards, guidance, and good practices as needed to support its uses and applications and as endorsed by the NRC (e.g., RG 1.200). As discussed in RGs 1.174 and 1.200, the quality of a PRA is measured in terms of its appropriateness with respect to scope, level of detail, and technical adequacy. Technical adequacy should be assessed via a peer review as described in RG 1.200.3 The applicant’s adherence to the recommendations provided in RGs 1.174 and 1.200 pertaining to quality and technical adequacy will result in a more efficient and consistent NRC staff 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. PRAs that meet the applicable supporting standards for Capability Category I and meet the high-level requirements 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
