摘要： Packaging for the transport and/or storage of radioactive materials includes a lateral packaging body around which an outer radiation protection envelope is disposed, which is made from a plurality of individual annular structures stacked on top of each other. Every structure includes an outer annular wall and a radial heat conductive wall, an outer end of which is secured to the wall, and an inner end of which is in contact with the lateral body. Furthermore, two directly consecutive structures delimit an annular cavity housing at least one radiation protection element, the cavity being closed radially towards the outside by the wall of one or both directly consecutive structures, and axially closed by the radial heat-conducting structure of one and the other of the two structures.

摘要： A racking device is provided for storing and/or transporting nuclear fuel assemblies. The racking device includes first stages (Ei−1, Ei+1) for neutron absorption and thermal conductivity, as well as second stages (E2i) for mechanical strength arranged so as to alternate with the first stages. Each first stage (Ei−1, Ei+1) includes first and second assemblies having interlacing notches (6a, 6b) made of aluminium alloy including boron. Each second stage (Ei) includes first and second structures (7a, 7b) stacked in a stacking direction (8) and each is made of one or more materials which are free of neutron-absorbing elements. The first and second structures (7a, 7b) are free of notches on their opposite edges in the stacking direction (8).

摘要： A protective shock absorbing element block made of rigid and brittle foam is provided with superficial or internal structure irregularities (20), having sharp edges in the foam to enable its immediate crushing by cracks propagating in depth throughout its entire volume, which facilitates its fragmentation with predicted characteristics. As a variant, a superficial hardening coating (28) could be used, to fill in the outer pores (27) in the foam, together with a lateral clearance with the envelope, or studs covering the inside of the envelope. Applies to shock resistant protective shock absorbing elements, particularly covering packagings exposed to drops.

摘要： A method for underwater packaging of radioactive materials includes creating a vacuum in a cavity of a cleaning device to automatically cause a portion of the cleaning device to move upward to actuate the cleaning device from an open position to a closed position; mounting the cleaning device inside a safe containment area of a transportation and/or storage device; placing the transportation and/or storage device in a pool after filling the safe containment area with water; loading a radioactive material into the safe containment area; closing the transportation and/or storage device using at least one cover; extracting the transportation and/or storage device from the pool; draining the water inside the safe containment area; and creating a pressure differential in the safe containment area to dry the safe containment area, wherein the pressure differential causes the cleaning device to automatically actuate from the closed position to the open position.
