ility Analysis C.1.3.12 (W) High Wind PRA C.1.3.7 (DA) Data Analysis C.1.3.13 (XF) External Flooding PRA C.1.3.11 (HS) Hazard Screening PRA C.1.3.14 (O) Other Hazards PRA C.1.3.15 (ESQ) Event Sequence Quantification C.1.3.16 (MS) Mechanistic Source Term Analysis C.1.3.17 (RC) Radiological Consequence Analysis C.1.3.18 (RI) Risk Integration B.4.2 The PRA elements should be developed consistent with the HLRs and associated SRs of the ASME/ANS non-LWR PRA standard, as endorsed with clarifications and qualifications in Appendix A of RG 1.247. Consistent with Staff Position C.2.1 in RG 1.247, all HLRs for a given PRA element should be met. B.5 PRA Level of Detail B.5.1 The PRA level of detail should be commensurate with the preliminary plant design and site characteristics described in the PSAR. B.5.2 An acceptable PRA level of detail should be established by using the process provided in Section 3, “Risk Assessment Application Process,” of the ASME/ANS non-LWR PRA standard. The staff has applied the process provided in Section 3 of the ASME/ANS non-LWR PRA standard and the results are presented in Tables B-2 and B-3, which follow the main body of this appendix. The CP applicant may use Tables B-2 and B-3 to establish the acceptability of the PRA level of detail.4 4 Table B-2 shows the alphanumeric identifiers of the underlined high-level requirements and their related supporting requirements in tabular format from ASME/ANS RA S 1.4 2021 applicable for a minimally acceptable PRA at the CP stage of DG-1404, Revision 1, App. B, Page 7 Alternatively, the CP applicant may perform a separate analysis using the process provided in Section 3 of the ASME/ANS non-LWR PRA standard and justify any deviations from or alternatives to Tables B-2 and B-3. B.6 Plant Representation and PRA Configuration Control B.6.1 The CP applicant should establish a PRA configuration control program to ensure that the CP PRA reasonably represents the preliminary plant design and site
