Abstract: Disclosed is a container assembly for the storage and disposal of material containing low-level nuclear wastes particularly suited for remote handling. A waste container has lifting lugs onto which a reusable grapple beam, made of rectangular tubing joined to form a polygon, is placed and attached to the lifting lugs by hooks. Screw jacks are used to tension the assembly and prevent inadvertent unlatching. The container is filled through the interior of the polygon into an opening in the container. The container may be filled, capped, handled, and the grapple beam removed by remote operations.

Abstract: Disclosed is a closure mechanism for sealing a nuclear waste disposal container. The mechanism allows partial closure of the container after internal apparatus have been inserted leaving a smaller opening for inserting and processing the waste material. Partial closure is achieved by inserting into the container an annular inner ring that fits against the container and by tightening an annular outer cap onto the inner ring, permitting access to the container through the aligned openings. After the waste material is loaded and processed, a sealing disk, axially joined to an inner plug to permit rotational but not linear movement, is passed through the outer cap opening and seats around the inner ring opening. The inner plug is tightened against the sealing disk by engaging matching threads on the inside of the outer cap opening.
