    • The invention provides a heterogeneously loaded type of fast reactor core in which a reduced number of target fuel assemblies containing minor actinide nuclides are heterogeneously dispersed and loaded. A wrapper tube for each of the target fuel assemblies is of the same shape and size as a hexagonal wrapper tube for an ordinary core fuel assembly. Each of target fuel rods within the wrapper tube contains 20 to 50% of minor actinide nuclides, and has a diameter more reduced than that of an ordinary core fuel rod. The number of the ordinary core fuel rods loaded in the ordinary core fuel assembly is 271 while the number of the target fuel rods loaded in the target fuel assembly is 331 or 397. Thirty to 50 such target fuel assemblies are heterogeneously dispersed and loaded in the fast reactor core.
    • 本发明提供了一种异质负载型快堆,其中减少数量的含少量锕系元素的目标燃料组件是非均匀分散和加载的。 用于每个目标燃料组件的包装管具有与用于普通核燃料组件的六边形包装管相同的形状和尺寸。 包装管内的每个目标燃料棒包含20-50%的次要锕系核素,其直径比普通核心燃料棒的直径更小。 装在普通核燃料组件中的普通核心燃料棒的数量是271,而装载在目标燃料组件中的目标燃料棒的数量是331或397。这样的目标燃料组件的三十到五十个这样的目标燃料组件被非均匀地分散并装载在 快堆芯。
