Abstract
Disposal container structure for the disposal of waste radioactive materials includes inner structure comprising a cover member with an inlet port and an annular seal surface portion, and depending filter structure attached to the cover structure that includes circumferential side wall structure and bottom wall structure that defines an enclosed chamber volume in which waste materials are introduced for storage therein through the inlet port. The container structure further includes outer structure that has circumferential side wall structure corresponding in shape to the filter structure of the inner structure, bottom wall structure that defines a chamber for receiving the filter structure of the inner component, and annular seal surface structure formed on the side wall structure for mating with seal surface structure of the inner structure to seal the storage chamber volume defined by the filter structure. Discharge passages across the seal surface provide flow paths for discharge of liquid from the region between the circumferential inner surface of the outer structure and the circumferential outer surface of the filter portion of the inner component. The container structure also includes drive surfaces for mating engagement with centrifuge structure for releasably engaging drive surfaces of a centrifuge system for subjecting the container structure to centrifugal forces in excess of about fifty Gs for separating water and similar liquids from solids retained within the chamber structure of the inner component.
