A Study on the Impact and Seismic Characteristics for Spent Fuel Storage and Transport Cask by Irradiation Effects

The spent fuel storage and transport cask must withstand various accident conditions such as fire, free drop and puncture in accordance with the requirement of the IAEA and domestic regulations. The spent fuel storage and transport cask should lnaintain the structural safety not to release radioactive material in any condition. And also the effects of the irradiation should be considered because the spent fuels stored in the cask for a long time. In this study, the mechanical properties of the cask after irradiation are assumed and applied to the impact analysis using ABAQUS/Explicit code and seismic analysis using ANSYS code. The stress on the cask is calculated and the effects of irradiation are studied.
