mental conditions associated with normal operation, maintenance, testing, and postulated accidents, including LOCA. SRP Section 3.9.3 provides guidance for the staff's review of the subject components and structures which are important to safety. This guidance includes consideration of loading effects and the resulting stresses (computed in accordance with the Code) associated with normal operation, maintenance, testing, and postulated accidents, including LOCA. This guidance is designed to comply with GDC 4. Meeting the requirements of GDC 4 provides reasonable assurance that components and structures important to safety are capable of performing their intended safety functions. 5. GDC 14 requires that the RCPB be designed, fabricated, erected, and tested so as to have an extremely low probability of abnormal leakage, of rapidly propagating failure, and of gross rupture. SRP Section 3.9.3 provides guidance for the staff's review of Code Class 1 components and component supports, including core support structures. This guidance cites the requirements of the Code to compute stresses and stress limits that are based on the loads and load combinations described in the SRP section. Meeting these requirements provides additional assurance that components that are part of the RCPB will be designed so as to have an extremely low probability of abnormal leakage, rapidly propagating
