To develop a FP removal method for treatment of spent molten salt solvent used in pyrometallurgical reprocessing of MA-containing metal fast reactor fuel, various electrochemical measurements were carried out in molten LiCl-KCl—CeCl₃ at 723 K using liquid Ga electrode and deposition behavior of Ce was investigated at concentrations above its solubility in liquid Ga.
