2段の晶析工程から成る新しい再処理システムの開発を行っている。本システムの第1段階ではUとPuがU-Pu共晶析により溶解液から回収される。U-Pu共晶析の基礎データ取得のため、U, Pu混合溶液及び照射済燃料溶解液を用いた実験室規模の試験を実施した。PuはUと共晶析したが、Puの晶析率はUに比べて低かった。FPは共晶析によりUやPuと分離され、Uに対するCs及びEuの除染係数は100以上であった。

A new reprocessing system with 2-stage crystallization process has been developed. In the first stage of the system, U and Pu are recovered from dissolver solution by U-Pu co-crystallization. Laboratory scale experiments were carried out with U and Pu mixed solution and irradiated fuel dissolver solution to obtain fundamental data on U-Pu co-crystallization process. Pu co-crystallized with U, but crystallization yields of Pu were lower than those of U. FPs were separated from U and Pu by co-crystallization, and decontamination factors of Cs and Eu to U in crystal were over 100.
