抽出溶媒と逆抽出液の流量減少の影響を調べるために遠心抽出器及び照射済MOX燃料溶解液を用いた単サイクル溶媒抽出システムの向流多段試験を実施した。抽出溶媒の流量を15%減少させるとラフィネートへのU及びPuのリークが起こり、共除染工程においてU及びPuの蓄積がみられた。一方、逆抽出液の流量を15%減少するとU及びPuにはそれほど大きな影響はみられなかった。

Counter current experiments in a single cycle solvent extraction system were carried out with centrifugal contactors to study flow rate reductions in extraction solvent and stripping solution with a dissolver solution of irradiated mixed oxide fuel. Uranium and Pu leaked to the raffinate with a 15% decrease in the extraction solvent flow rate, which brought about an accumulation of U and Pu in the co-decontamination section. On the other hand, a 15% decrease in the stripping solution flow rate did not affect the stripping of U and Pu so greatly.
