Container device for the storage of hazardous material, particularly for the ultimate disposal of nuclear fuel, and installation for manufacturing it

摘要

A container device (11) for the long-term storage of hazardous material, particularly for the ultimate disposal of nuclear fuel, comprises at least one elongate, cylindrical first containment body (A) having walls defining a first compartment (14) for accommodating at least one hazardous-material body (F) formed by the hazardous material or containing or supporting the hazardous material. The first compartment (14) comprises support means for supporting the hazardous-material body centrally in the first compartment and spaced from the walls thereof. The container device also comprises an elongate, cylindrical second containment body (B) having walls defining a cylindrical second compartment (22). The second compartment (22) comprises support means for supporting the first containment body (A) centrally in the second containment body (B) and spaced from the walls thereof. Passages are provided in at least one end wall of each of the first and second containment bodies for the introduction of wet concrete in respectively the first compartment (14) and the second compartment (22).
