ormed. Conformance with these requirements imposes specific restrictions to ensure that structures other than the containment will perform acceptably, commensurate with their intended safety function, when designed in accordance with the above standards. Meeting these requirements provides added assurance that the SSCs described here will perform their intended safety function. 3. Compliance with GDC 2 requires that SSCs important to safety be designed to withstand the effects of expected natural phenomena such as earthquakes, tornadoes, hurricanes, floods, tsunami, and seiches without loss of capability to perform their safety functions. The design bases for these SSCs shall reflect appropriate combinations of the effects of normal and accident conditions with the effects of the natural phenomena. To ensure that structures other than containment of a nuclear power plant are designed to withstand natural phenomena, it is necessary to consider the most severe natural 3.8.4-14 Revision 3 – May 2010 phenomena that have been historically reported with sufficient margin for the limited accuracy, quantity, and period of time in which the historical data have been accumulated. These data should be used to specify the design requirements of nuclear power plant components to be evaluated as part of CP, OL, COL, and ESP reviews, or for site parameter envelopes in the case of DCs, thereby ensuring that components important to safety will function in a manner that will maintain the plant in a safe condition. This section provides detailed acceptance criteria and cites appropriate regulatory guidance for design methodology, materials testing, and construction techniques acceptable to the staff. GDC 2 requires that structures other than containment be designed to withstand the effects of natural phenomena combined with those of normal and accident conditions without loss of capability to perform their safety function.
