    摘要： A transport container for nuclear fuel is provided, comprising an outer container provided with internal insulation, the insulation defining a cavity, the cavity being provided with four or more sleeve(s), one or more fuel container(s) being received within a sleeve, each of the fuel containers having a releasable lid, the volume of the fuel containers is at least 5% of the external volume of the outer container. The container allows substantially higher volume proportions of enriched fuel to be safely transported than is possible with prior art containers.

    摘要： A storage tank (1, 11) for radioactive fissile material solutions. The tank (1, 11) comprises at least one cell containing a radioactive solution (2, 12) and a solid neutron-absorbing material (4, 14) while preventing any risk of criticality. A network of substantially vertical tubes (3, 13) is arranged within said cell and metal walls completely separate the radioactive solution (2, 12) from the solid neutron absorbing material (4, 14). Said tubes 93) contain the radioactive solution (2) and are located in cavities defined by metal walls (4') within said neutron absorbing material (4). Alternatively, said tubes (13) contain the neutron absorbing material (14) and are located in compartments defined by metal walls (12') throughout the radioactive solution (12). Said tank occupies a reduced floor space.

    摘要： A magazine (1) for storage of nuclear fuel assemblies with spent nuclear fuel. The magazine (1) comprises a tubular casing which includes a number of channels (3) being formed from elongated intersecting first and second plates (8, 9). The plates (8, 9) are provided with a number of slits (12, 14, 20, 21) extending in the longitudinal directions of the plates (8, 9). The plates (8, 9) are assembled crosswise by inserting the slits of the first plate (8) into the slits of the second plate (9).

    摘要： A method of forming a neutron-absorbing tube or a section of such tube, and the resulting tube. An elongate, generally rectangular metal ingot having a hollow interior is formed with at least one elongate metal divider in the interior forming chambers. The chambers are filled with a uniformly dispersed mixture of finely divided boron and particles of a finely divided metal, the ingot is then soaked to an elevated temperature and hot rolled to form a thin, rigid neutron-absorbing sheet having opposite metal edge portions and an elongated metal spacer portion at each metal divider. The sheet is then longitudinally bent at each spacer portion. A tube is formed by welding one or more bent sheet along the side edge portions.
