t occur at the plant site. Designing the storage pool and fuel storage racks to meet seismic Category I requirements provides reasonable assurance that earthquakes will not cause a substantial coolant loss, a reduction in margin to criticality, or damage to the fuel assemblies. GDC 2 requirements provide assurance that natural phenomena will not prevent maintenance of a subcritical configuration and adequate cooling of the stored fuel. 2. GDC 4 requires that SSCs important to safety be designed to accommodate the effects of, and be compatible with, the environmental conditions of anticipated operating and accident conditions. This requirement includes protection against dynamic effects, including those of missiles, pipe whipping, and discharging fluids caused by equipment failures and from events and conditions outside the nuclear power unit. GDC 4 requires for new and spent fuel storage facilities a controlled and protected environment for the new and spent fuel and all SSCs necessary for safety. The spent fuel pool liner, the new and spent fuel assemblies, and the fuel storage racks must be protected from dynamic effects, including turbine and tornado missiles. Adequately thick spent fuel pool walls and adequate water levels usually provide the necessary protection from dynamic effects for SSCs within the pool. The new fuel and its storage racks also must be protected from dynamic effects to provide reasonable assurance that a substantial margin to criticality is maintained. GDC 4 requirements provide assurance that the new and spent fuel storage facilities will contain radioactive materials and maintain a subcritical configuration that can be cooled adequately in all environmental conditions, even after exposure to dynamic effects like missiles. 3. GDC 5 requires that SSCs important to safety not be shared among nuclear power units unless such sharing can be shown not to significantly impair their ability to perform safety functions, including, in an accident in
