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 720â¯K to 1000â¯K. The solubility of GdCl3 from 720â¯K to 850â¯K was determined from the phase diagram developed. The activity coefficient and apparent potential of GdCl3 with a concentration up to 3â¯mol% were also investigated. They both show a dependence on the concentration. From 0 to 3â¯mol%, the apparent potential increases by about 3% and the activity coefficient increases by about 50%.
