g the requirements of GDC 2 provides assurance that pumps, valves, and dynamic restraints important to safety are capable of withstanding the effects of severe natural phenomena while performing their safety functions during and after the occurrence of those phenomena, as applicable. 3.9.6-18 Revision 3 - March 2007 3. GDC 4 requires, in part, that components important to safety be designed to accommodate the effects of, and be compatible with, the environmental conditions associated with normal operation, maintenance, testing, and postulated accidents. Meeting the requirements of GDC 4 provides assurance the components are capable of withstanding those effects and continuing to perform their intended safety functions. 4. GDC 14 requires that the RCPB be designed to have an extremely low probability of abnormal leakage, rapidly propagating failure, and gross rupture. Meeting the requirements of GDC 14 provides assurance that RCPB components will have an extremely low probability of leakage or failure. 5. GDC 15 requires that the reactor coolant system be designed with sufficient margin to ensure that the design conditions of the RCPB are not exceeded during any condition of normal operation, including anticipated operational occurrences. 6. GDC 37 requires that the emergency core cooling system be designed to permit appropriate periodic pressure and functional testing to ensure the structural and leak tight integrity of its components as well as 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 emergency core cooling system and is intended to meet the requirements of GDC 37. Meeting the requirements of GDC 37 provides assurance that Emergency Core
