  • Patent number: 5102615
    Abstract: A container for storing and transporting radioactive material is provided comprising: a vessel, having an upwardly open cavity for accommodating radioactive material; and a cap covering the top surface of the vessel to seal the cavity. The vessel and cap walls have a core of radioactive shielding material such as cementatious, concrete enveloped and isolated within a continuous metal lining. The metal lining allows the container to be held under water, improves the impact resistance of the container and forms a barrier in a geological disposal facility. The lower edge of the cap and upper edge of the vessel are welded together to seal the cavity. The vessel includes lifting lugs for lifting the vessel and container.
