Draft Revision 4 - December 2012 4. Seismic subsystem analysis is reviewed under SRP Section 3.7.3. This includes, but is not limited to, seismic Category I substructures, such as platforms, frame support structures, yard structures; buried piping, tunnels, and conduits; concrete dams; and atmospheric storage tanks. 5. The design of seismic Category I structures for all applicable load combinations is reviewed under SRP Sections 3.8.1 through 3.8.5. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. The review of the design earthquake ground motion (safe shutdown earthquake (SSE); Operating Basis Earthquake (OBE), if applicable), the generic-site or site-specific soil properties, and the SSI analyses is an integral part of the overall review process for seismic Category I structures. II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. Title 10 of the Code of Federal Regulations (10 CFR) Part 50, General Design Criterion (GDC) 2 - 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 100, Subpart A, which is applicable to power reactor site applications before January 10, 1997, refers to Appendix A of this part for seismic criteria. 10 CFR Part 100, Appendix A indicates that the SSE and the OBE shall be considered in the design of safety-related SSCs. 10 CFR Part 100, Appendix A further states that the design used to ensure that the required safety functions are maintained during and after the vibratory ground motion associated with the SSE shall involve the use of either a suitable dynamic analysis or a suitable qualification test to demonstrate that SSCs can withstand the seismic
