  • Patent number: 4857262
    Abstract: A method and apparatus for separating the fuel rods (15) in a fuel element 8), whereby the former are retained in a bird cage arrangement (16, 18) between a head piece (19) and a foot piece (19'). The fuel elements (8) is located on a support table (6) with the help of a clamping arrangement (10). Before the fuel rods can be separated, the head piece and the foot piece are removed. In order to simplify removal of the fuel rods from the fuel element, to save space, and to minimize any risk of breakage after removal of the head piece (19) and the foot piece (19'), the bird cage arrangement (16,18) is progressively stripped from one layer of fuel rods to the next and from around the fuel rods. The exposed fuel rods are then lifted out of the fuel element (8) layer by layer and reshuffled in a more compact arrangement. A cutting tool (24), provided with a cutting disk head (26), is used to strip and separate the fuel rods with the help of a grappler (28).

  • Patent number: 4713199
    Abstract: The invention concerns a depository for radioactive waste and spent fuel cells comprising a concrete storage block in which several vertical storage and cooling channels are provided for accommodating the radioactive waste and the fuel cells. In order to provide an improved and safer concrete depository vis-a-vis the state of the art, the storage block is composed of several concrete blocks disposed beside and above one another. In the concrete blocks there are several vertical channels. The aligned channels of several concrete blocks placed on top of one another form storage and cooling channels for accommodating tubular storage containers for the radioactive waste and radioactive spent fuel cells. An annular gap is left for cooling air between the outer wall of the storage containers and the inner wall of the storage and cooling channels.

  • Patent number: 4532428
    Abstract: The invention is directed to a concrete shielding housing for receiving and storing a transportable fuel element container which is suitable for storage and filled with spent nuclear reactor fuel elements. The clear interior dimensions of the concrete shielding housing are somewhat larger than the outer dimensions of the container. During its temporary storage the fuel element container must be monitored with suitable measuring instruments. In order to make the monitoring as simple as possible, measuring probes are arranged on the inner wall surface of the shielding wall of the concrete shielding housing. The measuring probes are embedded in the concrete and are already in place and ready for use before the fuel element container is loaded into the concrete shielding housing.
