Abstract

A nuclear material cask is placed in a sealed zone submerged in fresh water in a container continuously supplied with fresh water under pressure. The container and cask are lowered into a contaminated water pool, where the cask is loaded and/or unloaded, while maintaining excess fresh water pressure to exclude contaminated water. The cask is then raised to the surface and removed from the container. The method is used in handling casks for long distance shipment of radioactive material. Radioactive contamination of the outer walls of the cask by the pool water is reduced.
