ion of the design of systems and components that interface with the Reactor Coolant System (RCS) with regard to ISLOCA is performed under SRP Sections 5.4.7 and 6.3. 12. Evaluation of the process used to minimize the degradation of materials due to corrosion is based upon the environmental conditions to which equipment will be exposed. This review is performed under SRP Section 6.1.1. 13. Verification of the adequacy of the analyses of subcompartment differential pressures resulting from postulated pipe breaks is performed under SRP Section 6.2.1.2. 14. Verification that the number and size of valves specified for the steam and feedwater systems have adequate pressure-relieving capacity is performed under SRP Section 10.3. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. 10 CFR 50.55a and GDC 1 as they relate to piping systems, pipe supports, and components being designed, fabricated, erected, constructed, tested, and inspected to 3.12-6 March 2007 quality standards commensurate with the importance of the safety function to be performed. 2. GDC 2 and 10 CFR Part 50, Appendix S with regard to design transients and resulting load combinations for piping and pipe supports necessary to withstand the effects of earthquakes combined with the effects of normal or accident conditions. 3. GDC 4, with regard to piping systems and pipe supports important to safety, being designed to accommodate the effects of, and to be compatible with, the environmental conditions of normal as well as postulated events, such as Loss-of-Coolant Accident (LOCA) and dynamic effects. 4. GDC 14, with regard to the RCPB of the primary piping systems being designed, fabricated, constructed, and tested to have an extremely low probability of abnormal leakage, of rapidly propagating failure, and of gross
