| titleOfInvention | Improved closure for casks containing radioactive materials |
| abstract | An improved closure (13) for covering and sealing a radioactive waste cask (1) of the type having an opening (128b) circumscribed by a ledge (126b) is disclosed herein. The closure (13) generally comprises an inner lid (122b) having an outer edge (124b) circumscribed by a gasket (130b) which is seatable over the ledge (126b) which circumscribes the opening (128b), and an outer lid (120b) which is securable around the cask opening (128b) by either a screw-type (134b, 128b) or a breech-lock mechanism. In either case, the outer lid (120b) may be rotated into locking engagement with the container (18) without imparting rotational forces to the gasket (130b) of the inner lid (122b) thereby protecting the gasket (130b) from unnecessary rubbing forces. To secure the gasket (130b) of the inner lid (122b) against the ledge (126b) of the cask opening (128b) the outer lid (120b) is provided with a plurality of jack bolts (139) engaged in threaded bores which extend completely through the outer lid (120b). After the closure (13) is secured over the cask opening (128b), these jack bolts (39) may be screwed through the outer lid (120b) into engagement against the inner lid (122b), thereby forcing the inner lid gasket (130b) into sealing engagement with the ledge (126b) of the cask opening (128b). |
