Dry casks are reinforced concrete cylindrical tanks that are used for the purpose of interim storage of spent nuclear fuel in the United States. These structures are typically located at independent spent fuel storage installations of nuclear facilities, with a higher concentration on the eastern coast. The storage tanks are freestanding structures that are prone to sliding and rocking during strong earthquakes, which might lead to impact between adjacent casks. Catastrophic consequences of damage to these structures make it necessary to study their seismic performance. To perform the seismic analysis, twelve parameters that might affect the seismic response were selected based on the literature. Latin hypercube sampling was employed to generate 160 configurations with different geometric, material, and structural properties. Finite element models of the problem were developed to determine the response of these structures under three-component ground motions. Sliding of the cask relative to its supporting pad was calculated, and probabilistic demand models were developed for the maximum sliding distance. The resulting parameterized models can support risk assessment of a broad range of reinforced concrete dry cask storage systems located in seismic zones. Furthermore, sensitivity analysis was performed to determine the parameters which have a significant influence on the seismic response of these structures. The sensitivity analysis can help designers have a better understanding of the effect of changing different parameters on the seismic response and fragility of this storage system.
