    • PROBLEM TO BE SOLVED: To attain prolonging the life of a core by increasing a reflector value in a reflector control system fast reactor.SOLUTION: A core 2 of a fast reactor 1 is enclosed by a cylindrical core barrel 35 arranged in a core outer portion inside a reactor vessel soaked in a primary cooling material C1, and is mainly constituted by hexagonal core fuel aggregation bodies 36. Special aggregation bodies 39, which include longitudinal and cylindrical housings 39 having a polygonal, circular, or elliptical shape different from the shape of the core fuel aggregation bodies 36 in a plane view, are loaded between the core barrel 35 and the core fuel aggregation bodies 36. The special aggregation bodies 39 are the bodies where the hollow parts of the housings 39 are vacuum or sealed by filling a substance with neutron reflective capability lower than that of the cooling material.
    • 要解决的问题:通过增加反射器控制系统快速反应器中的反射器值来延长芯的寿命。 解决方案:快堆1的核心2被布置在浸泡在主冷却材料C1中的反应器容器内的核心外部中的圆筒形芯筒35包围,并且主要由六边形核燃料聚集体36 具有与平面图中的核心燃料聚集体36的形状不同的多边形,圆形或椭圆形状的纵向和圆柱形壳体39的特殊聚集体39被装载在芯筒35和核心燃料聚集体 特殊聚集体39是通过填充具有比冷却材料的中子反射能力低的中子反射能力的物质来将壳体39的中空部分真空或密封的主体。 版权所有(C)2013,JPO&INPIT
