pplicant about the staff’s position and submits supplementary requests for additional information. The SAR or ESR and amendments responding to the requests for additional information are reviewed to determine that the information presented by the applicant is acceptable according to the criteria described in Section II (Acceptance Criteria) above. Based on information supplied by the applicant and information obtained from site visits, staff consultants, or literature sources, the reviewer independently identifies and evaluates the relevant seismic sources, including their capability, and determines the earthquake potential for each using procedures noted in Section II, Acceptance Criteria, above. The reviewer evaluates the GMRS as determined by the applicant using the site-specific conditions to ensure that the GMRS adequately characterizes the regional and local seismic hazard. To ensure that the safety implications of any new geologic information are reviewed, as described in SRP Sections 2.5.1 and 2.5.3, the staff proposes a geologic mapping license condition in the SER for each COL site where plant excavation and geologic mapping have not been completed prior to a license being granted. Through carrying out these procedures, the NRC staff reviews that the SAR uses methods acceptable for (1) conducting geological, geophysical, seismological, and geotechnical investigations; (2) identifying and characterizing seismic sources; (3) conducting a PSHA; (4) determining seismic wave transmission (soil amplification) characteristics of soil and rock sites; and (5) determining a site-specific, performance-based GMRS, satisfying the requirements of paragraphs (c), (d)(1), and (d)(2) of 10 CFR 100.23, and leading to the establishment of an SSE to satisfy the design requirements of Appendix S to 10 CFR Part 50. The steps necessary to develop the final SSE are described in Chapter 3, “Design of Structures, Components, Equipment and Systems,” of NUREG-0800, “Standard
