Abstract
This paper presents the results of a structural analysis to determine desig n variables such as the inner basket array type, and thicknesses of the out er shell, and the lid and bottom of a spent nuclear fuel disposal canister. The canister construction type introduced here is a solid structure with a cast iron insert and a corrosion resistant overpack, which is designed for the spent nuclear fuel disposal in a deep repository in the crystalline be drock, entailing an evenly distributed load of hydrostatic pressure from th e groundwater and high swelling pressure from the bentonite buffer. Hence, the canister must be designed to withstand these high pressure loads. Many design variables may affect the structural strength of the canister. In thi s study, among those variables, the array type of inner baskets and thickne sses of outer shell and lid and bottom are attempted to be determined throu gh a linear structural analysis. Canister types studied here are one for th e pressurized water reactor (PWR) fuel and another for the Canadian deuteri um and uranium reactor (CANDU) fuel.
