ections, as well as documentation criteria for design and construction controls. SRP Section 3.8.2 cites RG 1.57 for guidance regarding load combination equations, and ASME Code, Section III, Division 1, Subsection NE, provides acceptable design guidance and acceptance criteria. Meeting these criteria provides assurance that engineering analysis and design of steel containments for nuclear power plants will comply with 10 CFR Part 50, and that steel containments will perform their intended safety function to prevent or mitigate the spread of radioactive material. 2. Compliance with GDC 2 requires that SSCs important to safety be designed to withstand the effects of expected natural phenomena such as earthquakes, tornados, 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 the containment of a nuclear power plant is designed to withstand natural phenomena, it is necessary to consider the most severe natural phenomena that have been reported historically 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 early site permit (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. SRP Section 3.8.2 and RG 1.57 provide guidance related to load combination equations, and ASME Code, Section III, Division 1, Subsection NE, provides acceptable stress and deformation limits for evaluating the effects of natural phenomena, in combination with normal and accident conditions. Meeting this requirement
