| description | To provide a container for used nuclear fuel and a method of forming the container for used nuclear fuel, which can efficiently suppress loads on inner parts to be added when a neutron blocking member thermally expands.SOLUTION: A container 1 for used nuclear fuel includes: a main body 2 in a practically cylindrical shape; an outer casing 3 over the main body 2; and a plurality of neutron blocking members 41 arranged between the main body 2 and the outer casing 3. The neutron blocking members 41 contain hollow parts 42, respectively, which extend in the axial direction of the main body 2. When the respective neutron blocking members 41 thermally expand, their expansion allowances are formed near the sides of the hollow parts 42, respectively.SELECTED DRAWING: Figure 4
【課題】中性子遮蔽体が熱膨張したときに、内部の部品に負荷がかかることを効率的に抑制できる使用済み核燃料用容器及び使用済み核燃料用容器の製造方法を提供する。【解決手段】使用済み核燃料用容器１は、略筒状の本体２と、本体２を覆う外筒３と、本体２と外筒３との間に配置される複数の中性子遮蔽体４１とを備えている。各中性子遮蔽体４１の内部には、中空部４２が形成されている。各中空部４２は、本体２の軸線方向に延びている。そして、各中性子遮蔽体４１が熱膨張すると、熱膨張した各中性子遮蔽体４１は、各中空部４２側を膨張代として膨張する。【選択図】 図４ |
