• A phosphate conversion process has been developed to reduce the high-level radioactive waste (HLW) generated in metal-electrorefining. In this study, the results of thermodynamic phosphate conversion reaction calculations are examined experimentally. Rare Earth Element (REE) chlorides were discovered to be easily converted into phosphates. Furthermore, regarding the use of an additive in the phosphate conversion reaction, the high temperature behavior of lithium phosphate was evaluated in elucidating its thermodynamic properties.
