ssurance that piping systems, piping components and associated supports are designed to withstand the effects of expected natural phenomena combined with the appropriate effects of normal and accident conditions, without loss of capability to perform their safety functions. 3. Compliance with GDC 4 requires that the nuclear power plant SSCs 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, including LOCA. SRP Section 3.12 provides guidance for the staff's review of the piping systems, piping components and their associated supports connected to systems to ensure the functionality of 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 3.12-15 Revision 1 – April 2014 operation, maintenance, testing, and postulated accidents, including LOCA. This guidance is designed to comply with GDC 4. Meeting the requirements of GDC 4 provides assurance that piping systems, piping components and their associated supports and structures important to safety are capable of performing their intended safety functions. 4. Compliance with GDC 14 requires that the RCPB be designed, fabricated, erected, and tested so as to have an extremely low probability of abnormal leakage, rapidly propagating failure, and gross rupture. SRP Section 3.12 provides guidance for the staff's review of ASME Code Class 1 piping systems, piping components and their associated supports connected to systems to ensure the functionality of components and 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
