Abstract: The subject of the present invention is principally a transportation device for nuclear fuel which includes a compartment (2) to receive a casing loaded with irradiated fuel, the said compartment (2) including an opening (4) for loading and unloading of the casing (18) from the device and an opening (6) for applying a longitudinal force on the casing (18) causing it to move inside the compartment (2) in the direction of the unloading opening in order to unload it, through a force transmission component (32) which forms a biological shield.

Abstract: The present invention is principally a device for transferring a nuclear fuel canister between a container for transporting said canister and a device for storing said canister. The transfer device comprises a body and a slide of longitudinal axis, capable of sliding in said body along its longitudinal axis (Y), said slide comprising at least a first compartment (C1), for removing a plug from the transport container and a plug from the storage device, and a second compartment (C3) for allowing the canister to pass from the transport container to the storage device and, conversely, means for sealing the transfer between the transport container and a transfer device and between the transfer device and the storage device.

Abstract: A container for confining nuclear waste, including a sleeve of longitudinal axis closed at a first longitudinal end by a base and a second longitudinal free end via which the container is designed to be loaded, a plug configured to close the second longitudinal free end tightly, a flange fixed on the inner face of the sleeve to the side of the second longitudinal free end, the plug having at least one external diameter substantially equal to at least one internal diameter of the flange, the plug configured to be welded on the flange such that the welding zone is offset radially towards an interior of the container, relative to an inner face of the sleeve.

Abstract: Method for packing nuclear fuel in a cooling pond in a canister (12) located inside a container (10), comprising the steps of the immersion of the canister (12) and the container (10), filling the canister (12), fitting a sealing device (D) comprising caps and means of attaching a cap onto said canister (12) and of checking this attachment.

Abstract: A storage element for the storage of cases (16) full of nuclear fuel in the horizontal position, said element comprising ventilation means (19, 32) arranged on the sides of the element, so that storage stacks according to this invention can be created. The storage elements may have a cross-section in the shape of regular hexagon to optimise the storage density.

Abstract: Dangerous packages, such as high activity nuclear packages, are placed in adjacent compartments (22) formed in the body (10) of transport packing. The compartments (22) are closed by individually closure plugs (28) and by a common cover (34) that works in cooperation with one face (17) of the body (10) with three seals in series. Connectors installed on the cover (34) and opening up between the seals, are used to make an inspection of the helium confinement. The steel inner casing (24) in each compartment (22) is doubled up on the outside with a copper weld free casing (50). This arrangement significantly improves the confinement inspection, enables a global helium inspection, and if necessary can be used to isolate an unsealed compartment (22).
