| 摘要 |
A device for storing heat-generating hazardous material, particularly radio-active fuel for nuclear reactors, comprises a substantially cylindrical, reinforced concrete body (11) with a cylindrical through centre passage (13) and a plurality of axially elongate, substantially cylindrical storage spaces for accommodating the hazardous material which are disposed around and parallel to and radially spaced spaced from the centre passage. The storage spaces are formed by sealed storage vessels (21) containing a fluid coolant and made of a heat-conducting material and being encapsulated in the concrete body (11). Heat transferred inwardly from the storage vessels (21) is carried away from the device by air or other fluid coolant flowing upwardly in the centre passage (13). A storage vessel (21) for the storage device has an inner compartment (27) for accommodating the hazardous material and an outer compartment (25) surrounding the inner compartment (27) and forming therewith a closed circulation path for the fluid coolant.
