酸分配法における高Pu濃度フィード溶液条件におけるPuの分配挙動を調べるため、向流多段試験を行った。フィード溶液に比べてU/PuプロダクトのPu富荷度を1.51倍に高めることができた。Pu分配工程において、Pu重合体や第三相の生成はみられず、安定して遠心抽出器の運転が行われた。

For evaluating the Pu partitioning behavior under the condition of high Pu concentration in the feed solution by the acid split method, the counter current experiment was carried out. The Pu content in the U/Pu product was 1.51 times higher than that in the feed solution. In the Pu partitioning section, Pu polymerization and third phase formation were observed, and the operation of centrifugal contactors was stable.
