electrical and mechanical equipment, and associated supports, for the capability to resist seismic and dynamic loads. Pertinent staff positions include extensive and specific provisions for tests and analyses to consider all appropriate seismic and dynamic loads in combination with normal and accident loads. SRP Section 3.10 cites guidance for testing and analysis that is acceptable to the staff for ensuring that mechanical and electrical equipment will withstand all appropriate combinations of seismic and dynamic effects caused by natural phenomena. 3.10-12 Revision 3 - March 2007 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, 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 seismic and dynamic testing and analysis of electrical and mechanical equipment, and associated supports, to ensure that such equipment will withstand seismic and dynamic loads as a result of, or in combination with, other environmental loads. Meeting the requirements of GDC 4 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, thereby ensuring that such equipment can withstand the seismic and dynamic
