  • Patent number: 11355254
    Abstract: A leakage testing device for testing leakage of a nuclear fuel assembly (18) by sipping. The device includes a collection assembly (32) that is configured to close an upper end (24A) of a cell (24) of a storage rack (22) for storing nuclear fuel assemblies discharged from a nuclear reactor (4). The closing prevents water contained in the cell from escaping via the upper end of the cell. The collection assembly is configured to collect products containing possible fission products released by a nuclear fuel assembly contained in the cell.

  • Patent number: 9887017
    Abstract: A nuclear facility comprising an anchor device is provided. This anchor device comprises a female part and a male part. The female part includes a groove extending along a longitudinal axis. The groove has a width which decreases longitudinally and a transverse section. The male part includes a slider with a shape mating that of the groove and is able to be longitudinally inserted into the groove. The transverse section of the groove is configured so as to prevent the extraction of the slider out of the groove transversely to the longitudinal axis. The anchor device includes a locking device able to prevent the slider from longitudinally sliding out of the groove.

  • Patent number: 8259892
    Abstract: A container including a support having at least one first longitudinal support surface defining a longitudinal housing for receiving a nuclear fuel assembly, and a door having a second longitudinal support surface. The door is movable between a position of holding the nuclear fuel assembly between the two longitudinal surfaces and a released position in which the assembly is free with respect to the support. The container includes means for adjusting the transversal separation between the first and second surfaces in the holding position of the door.

  • Patent number: 5559843
    Abstract: The lower part (31) of the pole (10) carries an expansible bush (40) engaged and fixed on the outer surface of the part (31) by one of the ends (41) of the bush and comprising longitudinally extending slots defining resiliently bendable strips. A group of balls (39) mounted to be radially movable in openings (38) in the lower part (31) of the pole (10) and bearing against the bendable strips of the expansion bush are movable between a retracted position and a position for expanding the bush (40), by a cylindrical cam (36) connected to an actuating rod (20). The device permits inserting the locking sleeve (8) in the guide tube (13) without risk of deformation of the end strips of the guide tube (13).
