摘要

Radio-active waste in a hot cell B is removed by lifting a plug 36 closing an orifice in the lower wall 32 of the hot cell and transferring the waste through the orifice into an ash can 14 disposed in a flask 10 transportable on a carriage 28. The ash can 14 is thin-walled and made of resiliently deformable material, e.g. polyethylene, and is formed at its upper end with a groove 50 for receiving a cover 16. During filling of the ash can the cover 16 is attached to the plug 36 by jamming engagement of a disc 66 within a cylindrical extension 56 of the cover. The disc 66 is carried by a push rod 60 which may be retained in the retracted position, Fig. 1, by resilient members 70 engaging a groove 74. After the ash can 14 is filled the plug 36 is replaced and the push rod 60 is depressed so that the cover 16 snaps into the groove 50, Fig. 2. A table 30 carrying the carriage 28 is then lowered to disengage the flask 10 from a centering extension 40 and the flask is positioned beneath its cover 12. On raising the table 30, latches 44 retaining the cover 12 are released. The flask 10 closed by its cover 12 is brought to a waste disposal site where sliding doors 20, 22 at the base of the flask are opened so that the ash can 14 may drop out. In a modification (Fig. 3, not shown) the cover 16 is temporarily attached to the cover 12 instead of the cover 36 and the cover 12 carries the push rod.
