nce in NEI 20-09, Revision 1, “Performance of PRA Peer Reviews Using the ASME/ANS Advanced Non-LWR PRA Standard,” (Ref. B-22), Sections 3.2, A.3.1, and A.3.2, which is endorsed in RG 1.247 with no exceptions, provides an acceptable approach for performing a self- assessment. B.8.6 In addition to a self-assessment, a CP applicant may have the comprehensive and systematic search, some or all PRA elements, some or all screening analyses, or the PRA configuration control program peer reviewed prior to submittal of the CP application.5 Section 6 of the ASME/ANS non-LWR PRA standard, which is endorsed in Staff Position C.2.2 in RG 1.247 with exceptions, and NEI 20-09, Revision 1, which is endorsed in RG 1.247 without exception, provide an acceptable approach for performing a peer review. The purpose of a peer review is to determine whether the relevant HLRs and associated SRs established in the ASME/ANS non-LWR PRA standard, as endorsed in RG 1.247 with exceptions, have been met. The peer review should also confirm that the technical aspects of the PRA have been developed in a technically correct manner and assess the appropriateness of assumptions and approximations used in the PRA. As a result, completion of a peer review should reduce the need for an in-depth staff review of the PRA. 5 HLRs and SRs related to the comprehensive and systematic search for radionuclide sources, POSs, and hazards appear in various locations throughout the ASME/ANS non-LWR PRA standard. However, the standard does not provide HLRs and SRs for risk-informed supplemental evaluations. DG-1404, Revision 1, App. B, Page 9 Table B-2.
