Abstract
The effects of operating conditions such as crystal growing rate and initial impu rity concentration on separation(or concentration) of cesiu m and strontium fission products in the LiCl waste salt generated fro m an electro lytic reduction process of spent oxides on lab-scale layer melt crystallization process were analyzed. In a layer crystallizat ion process, impurities(CsCl and SrCl2) are concentrated in a s mall part of the LiCl salt due to the difference in the solubility in the melt phase and the solid l phase. The crystal growth rate strongly affects the crystal structure, therefore the separation efficiency, but the effect of the in itial Cs and Sr concentrations in LiCl mo lten salts was nearly negligible within the experimental range.
