Calculated thermodynamic properties of GdCl3 in LiCl-KCl eutectic molten salt
Source abstract
Abstract
Abstract The thermodynamic behaviors of lanthanides in molten salt are significant for the pyroprocessing of spent nuclear fuel. In this study, the ternary phase diagram of LiCl-KCl-GdCl3 system was assessed by the CALPHAD method using two-sublattice model. The liquidus surfaces were calculated and plotted from 720 K to 1000 K. The solubility of GdCl3 from 720 K to 850 K was determined from the phase diagram developed. The activity coefficient and apparent potential of GdCl3 with a concentration up to 3 mol% were also investigated. They both show a dependence on the concentration. From 0 to 3 mol%, the apparent potential increases by about 3% and the activity coefficient increases by about 50%.
