Abstract:
1. A container device for the long-term storage of hazardous material, particularly for the ultimate disposal of nuclear fuel, comprising an elongate, cylindrical inner containment body having a casing wall, an upper end wall, a lower end wall, a first compartment defined by the casing wall and the end walls for accommodating at least one hazardous-material body formed by the hazardous material or containing or supporting the hazardous material, particularly a hazardous-material body comprising a bundle of rod-shaped nuclear fuel elements, and support means in the compartment supporting the hazardous-material body centrally in the inner compartment and spaced from the casing wall and the end walls, and a cylindrical outer containment body having a casing wall, an upper end wall and a lower end wall a second cylindrical compartment which is defined by the casing wall and the end walls and within which the inner containment body is supported and spaced from the casing wall and end walls of the outer containment body, wherein a passageway extends through at least one of the end walls of the outer containment body and opens into the second compartment to pass self-compacting concrete into the second compartment, a passageway extends through at least one of the end walls of the inner containment body and opens into the first compartment, the passageway communicating with the second compartment so that self-compacting concrete can flow from the second compartment into the first compartment, and a passageway for discharging excess of self-compacting concrete from the top of the outer compartment is provided in the upper end wall of the outer containment body.
