| Abstract Scope |
Electrochemical processing of spent nuclear fuel in molten chloride salts generates complex radioactive salt waste. The removal of chlorine from this waste is a crucial step in waste processing. In this study, a procedure was developed for the dechlorination of an electrorefiner salt waste simulant called ERV3 salt based on the results of dechlorination with a simple salt mixture. The dechlorination of the simple salt mixture was evaluated using various phosphate precursors, atmospheres, and heating profiles, with the optimal conditions applied to the dechlorination of the ERV3 salt. This method allowed for the down selection of processes, ultimately revealing that the ERV3 salt can be effectively dechlorinated at the laboratory scale in an air environment at 600˚C with phosphoric acid as the phosphate precursor. These findings represent a significant step toward advancing the Technology Readiness Level of phosphate-based dechlorination methods and develops a strategy for future developments in dechlorination research. |
