Content:
al 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 inservice tests required by the ASME Code as well as other preoperational and inservice tests for pumps and valves to ensure their leak tight integrity as well as their operability and performance. This testing is specifically applicable 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 pumps and valves important to safety are capable of performing their intended safety function.93 6. Compliance with GDC 54 requires that piping systems penetrating the primary reactor containment be provided with leak detection and isolation capabilities. Such piping systems shall be designed with a capability to test the operability of the isolation valves periodically to determine if valve leakage is with acceptable limits. The acceptance criteria in SRP Section 3.9.6 cite inservice tests required by the ASME Code as well as other preoperational and inservice tests for valves to ensure their leak tight integrity as well as their operability and performance. This testing is specifically applicable to safety-related valves in system 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 important to safety are capable of performing their intended safety function.94 7. Compliance with 10 CFR 50.55a(f) requires that pumps and valves whose active function is required for safety be tested in accordance with the applicable revision of the ASME Code, as described therein. The acceptance criteria in SRP Section 3.9.6 cite inservice tests required by the ASME Code as well as other tests for pumps and valves to ensure their operability and performance. This testing is
