ABSTRACT:
Radioactive waste is loaded from a cell 10 into a drum 16 by sealing the drum about a port 12 in the cell, attaching the drum lid to the port door by clamp jaws 30 engaging a boss 76, withdrawing the port door and drum lid 69 into the cell in back-to-back fashion, loading the drum and replacing the lid. The lid has an annular lip 72, and the lid is deformable from a first state in which the lip engages the underside of the drum rim 65 and the lid engages the outer surface of the rim, and a second state in which the lip is free from engagement with the rim, thereby allowing removal of the lid.
The jaws are moved into clamping engagement by initial movement of the jaws relative to the door.
