ABSTRACT:
A device comprises a bag for covering a cask for transporting a used nuclear fuel to prevent the outer surface of the cask from contamination with the contaminated water of a fuel storage pool when the cask is immersed in the pool. An annular tube inflatable with a pressure gas injected thereinto is provided along the open end of the bag to hold the opening edge in pressing contact with the outer surface of the cask and thereby seal off the interior of the bag. Preferably the bag is provided with means for adjusting the pressure of the gas in accordance with the pressure of water at the depth at which the cask is positioned. The device is also useful for casks for transporting other radioactive fissionable materials.
