先進湿式再処理プロセスの晶析工程より回収するUNH結晶の精製技術を開発するため、MOX燃料溶解液を用いた結晶精製基礎試験を実施した。液体不純物においては発汗操作、固体不純物については融解操作によりUNH結晶の精製を試み、結晶精製技術開発に必要な基礎データを取得した。

For developing the crystal purification for UNH crystal obtained from crystallization process, crystal purification experiments were conducted with dissolver solution of MOX fuel. Sweating experiments were carried out for purification of liquid impurity, melting operation was attempted for separation of solid impurity. Basic data about development of the crystal purification process were obtained in our experiments.
