Conceptual Thermal Analysis of a Hot Cell Transportation Cask

A hot cell transportation cask is being developed to safely transport spent nuclear fuels and high level radioactive wastes generated from the pyroprocess. A cask to transport the radioactive materials is required to withstand the hypothetical accident conditions as well as normal transport conditions according to IAEA and domestic regulations. The regulations require that the cask should maintain the shielding, thermal and structural integrities to release no radioactive material. The objective of a thermal analysis is to verify that the thermal performance of the cask. The cask must remove the decay heat from the spent fuel to the environment without exceeding the operational temperature ranges of the cask seals or other components important to safety. The accessible surface temperature of a cask in still air at 38 .deg. C will not exceed 85 .deg. C under normal transport condition. In this study, Thermal analyses of the hot cell transportation have been carried out for conceptual design of the cask
