Container for the storage, transportation and ultimate disposal of low level nuclear wastes

This patent describes a cylindrical cask-like container adapted for the on-site storage, later shipment, and permanent disposal of low-level-radiation nuclear waste material. The cask-like container facilitates the handling and storage of such waste material while minimizing transfer of material and possible exposure which can be encountered in handling and shipping such material, the container comprising: a hollow right-circular cylindrical steel body member. The thickness of the hollow steel body member is predetermined to reduce at the outer surface of the container the radiation that is generated by the waste material the cask-like container is adapted to retain to a predetermined, safe level; and a steel bottom portion of the cask-like container having a circular configuration of predetermined dimensions slightly smaller than that of the hollow right-circular body member, and a thickness similar to that of the hollow right-circular body member. A recessed annular-conformed portion of predetermined dimensions is formed about the upper periphery of the bottom portion member and forming a ledge at the inner dimension thereof. The bottom portion member when interfitted into the bottom of the hollow right circular-member forms with the exterior surface of the right-circular member a recessed ledge of predetermined dimensions
