programs, is performed under SRP Section 3.10. 3.9.4-6 Revision 4 – March 2017 11. Evaluation of the adequacy of dynamic analyses under steady state and operational flow transient conditions and the proposed program for preoperational and startup testing of flow, acoustically, and mechanically induced vibration for CRDS components and assemblies internal to a vessel assembly is performed under SRP Section 3.9.2 and RG 1.20, Revision 4. 12. The adequacy of any electrical supply lines to the CRDM latching mechanism is reviewed under SRP Section 8.3.1, “A-C Power Systems (Onsite),” or 8.3.2, “D-C Power Systems (Onsite),” as applicable. 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. GDC 1 and 10 CFR 50.55a, as they relate to the CRDS, require that the CRDS be designed to quality standards commensurate with the importance of the safety functions to be performed. 2. GDC 2, as it relates to the CRDS, requires that the CRDS be designed to withstand the effects of an earthquake without loss of capability to perform its safety functions. 3. GDC 14, as it relates to the CRDS, requires that the RCPB portion of the CRDS be designed, constructed, and tested for the extremely low probability of leakage or gross rupture. 4. GDC 26, as it relates to the CRDS, requires that the CRDS be one of the independent reactivity control systems that is designed with appropriate margin to assure its reactivity control function under conditions of normal operation, including anticipated operational occurrences. 5. GDC 27, as it relates to the CRDS, requires that the CRDS be designed with appropriate margin, and in conjunction with the emergency core cooling system, be capable of controlling reactivity and cooling the core under postulated accident conditions. 6. GDC 29, as it relates to
