d the fuel pool structure, including the pool slab and fuel pool liner, should be evaluated for accident load combinations which include the impact of the spent fuel cask, the heaviest postulated load drop, and/or accidental drop of the fuel assembly from the maximum height. The review will evaluate the acceptable limits (strain or stress limits) on a case-by-case basis, but in general, the applicant is required to demonstrate that the functional capability and/or the structural integrity of each component is maintained. The specific loads and load combinations are acceptable if they conform with the applicable portions of this SRP, Subsection II.3, and Table 1 provide in this Appendix. 5. Design and Analysis Procedures American National Standards Institute, N210-76, ARequirements for Light Water Reactor Spent Fuel Storage Facilities at Nuclear Power Plants, Design,@ provides general information regarding design of spent fuel pool racks. Details of the mathematical model, including a description of how the important parameters are obtained, should be provided. The details should include the methods used to incorporate any gaps between the support systems and gaps between the fuel bundles and the guide tubes; the methods used to lump the masses of the fuel bundles and the guide tubes; the methods used to account for the effect of sloshing water on the pool walls; and the effect of submergence on the mass, the mass distribution, and the effective damping of the fuel bundle and the fuel racks. Design and analysis procedures in accordance with this SRP, Subsection II, are acceptable. The effect on gaps, sloshing water, and increase of effective mass and damping resulting from submergence in water should be quantified. If the spent fuel racks are designed to be free standing (i.e., without connections to the pool walls/floor), then their response involves a complex combination of motions that includes sliding, rocking, and twisting and involves impacts between the fuel
