摘　　要：提出在快中子反应堆中布置慢化靶件嬗变压水堆的核电厂卸料元件中的亚锕元素优化方案。快堆满功率动行３ 年后可消灭（Ｉｎｃｉｎｅｒａｔｅ）亚锕元素９３９ ｋｇ（约装载量的６７％ ），其中裂变了４８９ ｋｇ（约装载量的３５％ ）。其消灭量和消灭率均为国际上普遍提出的均匀布置方案的２～３ 倍。The effect of contained hydrogen and minor actinides (MAs) in the target loaded in FR on the core performance and MAs transmutation characteristic was analyzed in this paper. An optimum case was proposed to offer good core performance with MAs incineration about 67%(939kg) and MAs fission about 35%(489kg)through 3 years of reactor operation. It is about 2~3 times larger than currently incineration method by loading MAs homogeneously in the FR and PWR.
