CsCl Separation From a LiCl-CsCl Mixture by Using a Crystallization Approach
- Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)
Separation of CsCl and SrCl{sub 2} from LiCl was carried out by using a noble separation technology, the Czochralski crystallization method. It was experimentally confirmed that Cs as well as Sr could be simultaneously separated from a LiCl molten salt by the suggested crystallization process without any kind of additive or adsorption media. The concentrations of Cs and Sr in the LiCl were decreased from 1.53 wt% and 4.18 wt% in the initial salt to a minimum of 114 ppm and 135 ppm in the grown LiCl crystal respectively. The separation mechanism of Cs and Sr is described by the solubility difference of the solutes between the molten and the solid states. It is expected that the total amount of salt waste could be drastically decreased, because most of the LiCl could be recovered for recycling to the electroreduction process. (authors)
