Content:
to consider the most severe natural 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, or 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 3.8.1 and RG 1.136 provide guidance related to acceptable load combination equations, and ASME Code Section III, Division 2, Section CC, provides stress and deformation limits for evaluating the effects of natural phenomena, in combination with normal and accident conditions. Meeting these requirements and criteria provide assurance that concrete containment structures will be designed to withstand the effects of natural phenomena without loss of capability to perform their intended function. 3. Compliance with GDC 4 requires that nuclear power plant SSCs important to safety be designed to accommodate the effects of and be compatible with environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including LOCAs, and be appropriately protected against dynamic effects, including the effects of missiles, pipe whipping, and discharging fluids, that may result from equipment failures and from events and conditions outside the nuclear power unit. SRP Section 3.8.1 provides guidance related to load combinations, acceptance criteria, standards, and codes to assure compliance with GDC 4. Meeting these requirements and criteria provide assurance that concrete containments will withstand loads from internal events, such as those described above, and from external sources such as explosive hazards in proximity to the site, potential aircraft crashes (nonterrorism-related incidents),
