Content:
iewed under SRP Section 3.7.2. 4. The seismic subsystem analysis for some components (e.g., buried piping, tunnels, and atmospheric tanks), which utilize the design ground motion developed in this SRP section, is reviewed under SRP Section 3.7.3, “Seismic Subsystem Analysis Review Responsibilities.” 5. For DC applications and COL applications referencing a DC, review of the site parameters in the Design Control Document (DCD) Tier 1 and Chapter 2 of the DCD 3.7.1-7 Revision 4 – December 2014 Tier 2 submitted by the applicant is performed under SRP Section 2.0, “Site Characteristics and Site Parameters.” 6. Review of the Probabilistic Risk Assessment is performed under SRP Section 19.0, “Probabilistic Risk Assessment And Severe Accident Evaluation For New Reactors,” in conjunction with DC/COL-ISG-020, “Interim Staff Guidance on Implementation of a Probabilistic Risk Assessment-Based Seismic Margin Analysis for New Reactors,” for potential risk significance of SSCs and the risk-based susceptibility of risk significant SSCs to failure due to seismic hazards. The results of the reviews for the OBE and the SSE site-specific free-field ground motion, soil properties, etc., are used as an integral part of the seismic analysis review of seismic Category I SSCs. II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. 10 CFR Part 50, Appendix A, General Design Criterion (GDC) 2, “Design Bases for Protection against Natural Phenomena.” - The design basis shall reflect appropriate consideration of the most severe earthquakes that have been historically reported for the site and surrounding area with sufficient margin for the limited accuracy, quantity, and period of time in which historical data have been accumulated. 2. 10 CFR Part 50, Appendix S is applicable to applications for a DC or COL pursuant to 10 CFR Part 52 or a CP or OL pursuant to 10 CFR Part 50 on or
