heric cleanup system and is intended to meet the requirements of GDC 43. Meeting the requirements of GDC 43 provides assurance that containment atmospheric cleanup system pumps and valves important to safety will perform their safety intended function. 3.9.6-19 Revision 3 - March 2007 9. GDC 46 requires that the cooling water system be designed to permit appropriate periodic pressure and functional testing to ensure the structural and leak tight integrity of its components and the operability and performance of the active components of the system. 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 pumps and valves to ensure their leak tight integrity and their operability and performance. This testing specifically applies to safety-related pumps and valves in the cooling water system and is intended to meet the requirements 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 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 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 safety-related valves 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 that applicants
