to develop the PRA. B.8.3 Consistent with NEI 21-07, Revision 1, Section 2.1.1, page 24, the CP applicant should describe its ultimate intended approach for qualifying the PRA. the two-step licensing process under 10 CFR Part 50. Likewise, Table B-3 shows the related alphanumeric identifiers for a PRA that is more than minimally acceptable at the CP stage. The in-line entry associated with each supporting requirement is either “YES,” “CC I,” or “CC II.” A “YES” entry indicates the supporting requirements for CC I and CC II (i.e., the two types of capability categories in ASME/ANS RA S 1.4 2021) are applicable because the supporting requirement is the same for both capability categories. An entry of either “CC I” or “CC II” indicates the minimum applicable supporting requirement associated with that capability category. DG-1404, Revision 1, App. B, Page 8 B.8.4 The CP applicant should conduct a self-assessment to demonstrate that all PRA-related analyses have been developed and used in a technically acceptable manner, including the appropriateness of assumptions and approximations. The self-assessment, thus, should provide a basis for asserting that the PRA is acceptable for implementing the LMP methodology leading up to submittal of the CP application. To this end, the self-assessment should review: 1. The comprehensive and systematic search used to identify radiological sources, POSs, and hazards. 2. The PRA logic models (including the scope, level of detail, and elements), screening analyses, risk-informed supplemental evaluations, and credit for DBHLs. 3. The CP applicant’s PRA configuration control program used to ensure that PRA-related analyses represent the as-designed, as-to-be-built, and as-to-be-operated plant. B.8.5 The guidance 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
