Abstract: Spent fuel storage casks installed on reinforced concrete pads must be qualified for kinematic stability and stress compliance under the postulated Design Basis Earthquake for the facility. A dynamic analysis method to predict the response of a loaded cask subjected to 3-D seismic excitation is presented in this paper. The methodology permits parametric evaluation of variables such as cask-to-pad interface friction coefficient, fuel-to-storage cell gaps, fuel basket stiffness, and fuel compliance characteristics. A set of acceptance criteria to ensure stability with a margin of safety appropriate for a nuclear installation are also proposed for possible adoption by the regulatory authorities.
