cooled during all credible storage conditions and to limit offsite exposures in the event of significant release of radioactive materials from the fuel. The requirements of GDC 2 are imposed to verify that the structures, systems, and components of the spent fuel storage facility are designed to withstand the effects of natural phenomena that might occur at the plant site, thereby ensuring that spent fuel will be maintained in a subcritical array. Position C.2 of Regulatory Guide 1.13; the applicable portions of Regulatory Guide 1.29; Regulatory Guide 1.117; and ANS 57.2 paragraphs 5.1.1, 5.1.3, 5.1.12, 5.3.2, and 5.3.4, provide guidance acceptable to the staff for meeting these requirements. Meeting the requirements of GDC 2 provides assurance that stored spent fuel will be maintained in a subcritical configuration that can be adequately cooled after a natural phenomena event.49 2. Compliance with GDC 4 requires that structures, systems, and components important to safety be designed to accommodate the effects of, and be compatible with, the environmental conditions associated with normal operations, maintenance, testing, and DRAFT Rev. 4 - April 1996 9.1.2-6 postulated accidents, including loss of coolant. This requirement includes protection against dynamic effects, including the effects of missiles, pipe whipping, and discharging fluids resulting from equipment failures and from events and conditions outside the nuclear power unit. GDC 4 requires that a spent fuel storage facility provide a controlled environment that will facilitate maintaining the fuel in a coolable and subcritical geometry. In addition, the facility is required to protect the fuel from the effects of missiles and jet impingement forces associated with turbine failure, natural phenomena (including tornadoes), and pipe breaks. Position C.2 of Regulatory Guide 1.13, Regulatory Guides 1.115 and 1.117, and appropriate paragraphs of ANS 57.2 provide guidance acceptable to the staff for meeting this
