.9.3-11 Revision 2 - March 2007 Meeting these requirements provides reasonable assurance that components that are part of the RCPB are capable of performing their intended safety functions and prevent the spread of radioactive materials. 6. GDC 15 requires that the reactor coolant system (RCS) and associated auxiliary, control, and protection systems be designed with sufficient margin to assure that the design conditions of the RCPB are not exceeded during any condition of normal operation, including anticipated operational occurrences. 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 RCS are 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. This guidance is designed to be in accordance with GDC 15. Meeting these requirements provides reasonable assurance that the reactor coolant pressure boundary is capable of performing its intended safety function and prevent the spread of radioactive materials. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. Loading Combinations, System Operating Transient, and Stress Limits. The objectives in reviewing the loading combinations and stress
