e to the staff for ensuring that mechanical and electrical equipment will withstand all appropriate combinations of seismic and dynamic effects caused by natural phenomena. Meeting the requirements of GDC 2 provides assurance that the seismic and dynamic qualification of electrical and mechanical equipment important to safety will be performed in accordance with criteria and standards (or their equivalent) cited in this SRP section, 3.10-15 Draft Revision 4 – August 2015 thereby ensuring that such equipment can withstand the seismic and dynamic load effects of natural phenomena in combination with normal and accident conditions. 3. Compliance with GDC 4 requires 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, including LOCAs and dynamic effects (e.g., pipe whip, missiles, and discharging fluids). GDC 4 applies to this SRP section because the reviewer evaluates dynamic testing and analysis of electrical and mechanical equipment, and associated supports, to ensure that such equipment will withstand dynamic loads as a result of, or in combination with, other environmental loads, which may include or result from seismic loads. Meeting the requirements of GDC 4 provides assurance that the dynamic qualification of electrical and mechanical equipment important to safety will be performed in accordance with criteria and standards (or their equivalent) cited in this SRP section, thereby ensuring that such equipment can withstand the dynamic load effects of environmental conditions associated with normal and accident conditions, including seismic events. 4. Compliance with GDC 14 requires that the RCPB be tested to demonstrate an extremely low probability of abnormal leakage, rapidly propagating failure, and gross rupture. GDC 14 applies to this SRP section because the reviewer evaluates seismic and dynamic
