摘要

The invention relates to a long-term storage device (1) intended to receive a containment case (3) containing radioactive materials, where this device includes a main body (2) having an inner surface delimiting a housing (7). 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 (9) delimiting a cavity (4) 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 (9).
