Claims (3)
- 弱塩基性陰イオン交換樹脂を充填した樹脂柱に、使用済燃料の希塩酸溶解液を供給し、次いで希塩酸を通液することにより、白金族元素群を樹脂に吸着させ、白金族元素群を含まない使用済燃料溶離液を流出させ、その後、樹脂に吸着されている白金族元素群を分離・除去する第1の工程、
弱塩基性陰イオン交換樹脂を充填した樹脂柱に、前記第1の工程で白金族元素群を除いた使用済燃料溶液を濃塩酸溶液に転換して供給し、次いで濃塩酸を通液することによりセシウムなどの核分裂生成物元素と希土類元素を含む群を流出させ、更に6M以上の塩酸を通液することにより3価マイナーアクチニド元素群を流出させ、その後、希塩酸を通液することによりプルトニウムを主体とする燃料成分元素群を流出させ、これによってセシウムなどの核分裂生成物元素と希土類元素を含む群、3価マイナーアクチニド元素群、及びプルトニウムを主体とする燃料成分元素群の3群に相互分離する第2の工程、
を具備していることを特徴とする使用済燃料の群別分離方法。 - 樹脂柱に充填する樹脂が、ピリジンあるいはイミダゾールあるいはアルキルアミンを樹脂化した一級、二級、三級の弱塩基性陰イオン交換樹脂であり、分離操作を常温で行う請求項1記載の使用済燃料の群別分離方法。
- 樹脂柱に充填する弱塩基性陰イオン交換樹脂として、弱塩基性陰イオン交換樹脂を多孔質シリカ担体もしくは溶液中で化学変化しない物質で作られた多孔質担体中に坦持したもの、もしくは樹脂自身を多孔質体としたものを用いる請求項2記載の使用済燃料の群別分離方法。
