        Separation of CsCl from LiCl-CsCl Molten Salt by Cold Finger Melt Crystallization

        JOSHUA R. VERSEY,SUPATHORN PHONGIKAROON,Michael F. Simpson 한국원자력학회 2014 Nuclear Engineering and Technology Vol.46 No.3

        This study provides a fundamental understanding of a cold finger melt crystallization technique by exploring the heat andmass transfer processes of cold finger separation. A series of experiments were performed using a simplified LiCl-CsClsystem by varying initial CsCl concentrations (1, 3, 5, and 7.5 wt%), cold finger cooling rates (7.4, 9.8, 12.3, and 14.9 L/min),and separation times (5, 10, 15, and 30 min). Results showed a potential recycling rate of 0.36 g/min with a purity of 0.33wt% CsCl in LiCl. A CsCl concentrated drip formation was found to decrease crystal purity especially for smaller crystalformations. Dimensionless heat and mass transfer correlations showed that separation production is primarily influenced byconvective transfer controlled by cooling gas flow rate, where correlations are more accurate for slower cooling gas flow rates
