formed. The provisions for functional design and IST programs for pumps, valves, and dynamic restraints in this SRP section are based on sound engineering principles as well as operating experience at nuclear power plants. Meeting the requirements of 10 CFR 50.54(jj), 10 CFR 50.55(i), and GDC 1 provides assurance that pumps, valves, and dynamic restraints important to safety are capable of performing their intended safety functions. 2. GDC 2 requires, in part, that components important to safety be designed to withstand the effects of severe natural phenomena, combined with appropriate effects of normal and accident conditions, without a loss of capability to perform their safety functions. Meeting the requirements of GDC 2 provides assurance that pumps, valves, and dynamic restraints important to safety are capable of withstanding the effects of severe 3.9.6-32 Revision 4 – March 2017 natural phenomena while performing their safety functions during and after the occurrence of those phenomena, as applicable. 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 that 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, fabricated, erected, and tested 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 and associated auxiliary, control, and protection systems be designed with sufficient margin to ensure that the design conditions of the RCPB are not exceeded during any condition of
