nts of GDC 46. Meeting the requirements of GDC 46 provides assurance that cooling water system pumps and valves important to safety are capable of performing their intended safety function. 10. GDC 54 requires, in part, that piping systems penetrating the primary reactor containment be provided with leak detection and isolation capabilities. Such piping systems should be designed with a capability to test the operability of the isolation valves and associated apparatus periodically to determine if valve leakage is within acceptable limits. The acceptance criteria in SRP Section 3.9.6 cite ISTs required by the OM Code as well as other preservice and inservice tests for valves to ensure their leak tight integrity and their operability and performance. This testing specifically applies to valves within the scope of the IST program in systems that penetrate the primary containment and is intended to meet the requirements of GDC 54. Meeting the requirements of GDC 54 provides assurance that valves in such systems are capable of performing their intended safety function. 11. Appendix B to 10 CFR Part 50 requires, in part, that applicants establish and execute an acceptable quality assurance program, including design, fabrication, construction, testing, and records control. Meeting the requirements of Appendix B to 10 CFR Part 50 provides assurance that designs, tests, IST programs and documentation for pumps, valves, and dynamic restraints will comply with established standards and criteria, thereby ensuring that such equipment will be capable of performing its intended safety functions. 12. 10 CFR 50.55a(f) for pumps and valves, and 10 CFR 50.55a(g) for dynamic restraints, require that such pumps, valves, and dynamic restraints whose function is required for safety be assessed for their operational readiness in accordance with the applicable revision of the OM Code, as described therein. In 10 CFR 50.55a(b)(3), the regulations take exception to, or supplement, the OM
