摘要

Method and apparatus for dismantling, shearing and compacting a fuel assembly skeleton. A frame (28) is provided which can be placed into the transfer canal (7) of a fuel-handling building for severing a bottom nozzle from the thimble tubes and grids of the skeleton. After compacting the remainder of the skeleton, the thimble tubes and grids are further severed into shorter pieces, and the shortened compacted severed pieces are placed into a container (30) for off-site shipment or on-site storage.
