Reactive-crystallization method for purification of LiCl–KCl eutectic salt waste
In this study, a reactive-crystallization method was introduced for the purification of LiCl–KCl salt waste generated in pyrochemical processes, wherein the salt was purified and impurities were precipitated using Li2CO3. The element separation efficiencies of group I/II and rare-earth elements were found to be > 90%. In addition, the metal corrosion generated during this process was mostly present in the precipitate phase, and the dissolved metal corrosion in the eutectic salt was suppressed to a few ppm. The feasibility of this process was confirmed by thermodynamic calculations. Reactive-crystallization can also be applied to other salt waste systems, such as MSR nuclear fuel treatment and molten salt chemistry for impurity purification.
