超臨界流体を用いた全アクチニド一括分離システムについての主要工程の設計を実施した。主要工程については多系列化が必要となったため、経済性の向上効果は小さいが、廃液処理については大幅な低減が可能との評価結果を得た。設計結果をもとに分配までを超臨界流体で行う改善案をまとめた。

Main process of actinides co-extraction system with direct extraction process using supercritical fluid was designed. The improvement effect of the cost performance was small because multiple lines were needed about main process. But we got the evaluation result that it is possible to reduce substantially about waste liquid treatment. Based on the result, the improvement which uses supercritical fluid for partitioning was gathered.
