The invention relates to a long-term storage device () intended to receive a containment case () containing radioactive materials, where this device includes a main body () having an inner surface delimiting a housing (). According to the invention, in an unloaded configuration, in which the containment case containing radioactive materials is absent from the storage device, the latter includes a storage case () delimiting a cavity () to receive the containment case, where the storage device also includes ventilation means allowing air to circulate between the exterior of the storage device and a space delimited between the inner surface of the main body and the storage case ().

Long-term storage device including a ventilated storage case intended to house a containment case containing radioactive materials

The invention concerns a cask for a canister containing radioactive material, comprising a canister extraction assembly and designed so that it can bring the canister to an extraction position inside the cask housing in which this canister is free of any contact with the inner surface. Also, one of two elements from among a carriage and a support structure of the assembly is provided with a guide ramp cooperating with a ramp follower provided on the other of the two elements, the ramp being designed so that a relative translational movement between the carriage and the structure, in the longitudinal direction of the cask, causes the changeover of the two elements from a drawn-together position to a drawn-apart position, or conversely.
