Chlorination of UO $_{2}$ , PuO $_{2}$ and rare earth oxides using ZrCl $_{4}$ in LiCl-KCl eutectic melt

Sakamura, Yoshiharu*; Inoue, Tadashi*; Iwai, Takashi; Moriyama, Hirotake*

A new chlorination method using ZrCl $_{4}$ in a molten salt has been investigated for the pyrometallurgical reprocessing of spent oxide fuels. UO $_{2}$ , PuO $_{2}$ and rare earth oxides(La $_{2}$ O $_{3}$ , CeO $_{2}$ , Nd $_{2}$ O $_{3}$ and Y $_{2}$ O $_{3}$ ) were allowed to react with ZrCl $_{4}$ in a LiCl-KCl eutectic salt at 500 $^{circ}$ C to give a metal chloride solution and a precipitate of ZrO $_{2}$ . By keeping the system quite still, the solution settled so that the ZrO $_{2}$ precipitate could be separated.
