Content:
clear 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 3.8.5, which also refers to SRP Section 3.8.4, provides detailed acceptance criteria and cites appropriate regulatory guidance for design methodology, materials testing, and construction techniques that are acceptable to the staff. GDC 2 requires that the design of structures other than containment be able to withstand the effects of natural phenomena combined with the effects of normal and accident conditions without losing the capability to perform their safety functions. The primary function of a foundation is to transmit the loads imposed by the superstructure to the foundation material, bedrock, and/or soil supporting the structure. Foundations must be designed to interact with the structures they support. Consequently, it is necessary to specify the most severe natural phenomena (e.g., earthquakes) likely to occur as a function of their frequency of occurrence. The load combinations and specifications cited in these SRP sections provide acceptable engineering criteria to accomplish that function. Meeting these requirements provides added assurance that the design of foundations of structures other than containment will withstand the effects of natural phenomena and will perform their intended safety functions. 4. Compliance with GDC 4 requires that the design of nuclear power plant SSCs important to safety (1) accommodate the effects of, and be compatible with, environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of-coolant accidents and (2) appropriately protect against dynamic effects, including the effects of missiles, pipe whipping, and discharging fluids, that may result from equipment failures
