component supports. 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 assurance that piping systems connected to components that are part of the RCPB will be designed so as to have an extremely low probability of abnormal leakage, rapidly propagating failure, and gross rupture. This guidance is designed to comply with GDC 14. 3.12-16 Draft Revision 1 - June 2013 Meeting the requirements of GDC 14 provides assurance that piping systems that are connected to components that are part of the RCPB are capable of performing their intended safety functions. 5. Compliance with GDC 15 requires that the RCS 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. SRP Section 3.12 provides guidance for the staff's review of the design and analysis of ASME Class 1 piping systems and associated supports connected to RCS components. This guidance cites the requirements of the ASME Code used to compute stresses and stress limits that are based on the loads and load combinations described in this SRP section. Meeting these requirements provides additional assurance that piping systems and associated supports (connected to components that are part of the RCS) will remain functional with sufficient margins of safety to ensure that the design conditions of piping systems and their associated supports connected to RCPB components are not exceeded during any condition of normal operation, including anticipated operational occurrences. This guidance is designed to comply with GDC 15. Meeting the requirements of 10 CFR Part 50, Appendix A, GDC 15 provides assurance that the piping systems will remain functional under all postulated design condition and ensures that RCPB components are capable of performing
