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 seismie excitation is presented in this paper. The methodology permits parametric evaluation of variables such as cask-to-pad friction coefficient, MPC-to-overpack gap, basket stiffness, and fuel compliance characteristics. A set of acceptance criteria to ensure stability with a large margin of safety are also proposed for possible adoption by the regulatory authorities.
