Accident Impact Analysis of a Spent-Fuel Storage Transportation Package

Packages used for the storage and transportation of radioactive spent fuel must demonstrate the ability to withstand severe impact scenarios such as those established by the Atomic Energy Control Board (AECB 1983) in Canada and the International Atomic Energy Agency (IAEA). One such package is the Dry Storage Container (DSC) for transporting and storing used fuel. Structural assessments of the package design subject to postulated impact scenarios included a 9-metre centre of gravity over comer drop, a 1- metre pin drop over the welded flange and a !-metre lid pin drop on the lid region. lmpact simulations were carried out on full scale analytical models using an in-house nonlinear fmite element code (Sauve 1993). The simulations were supported by validation experiments conducted on a half scale DSC
