Gadolinium is one of the many constituents of spent nuclear fuel. The behavior of gadolinium in molten eutectic LiCl-KCl needs understanding for pyrochemical processing operations like electrochemical rare earth drawdown and electrorefining. For this paper, the thermodynamic and electrochemical properties of GdCl3 were studied as a function of concentration and the influence of other fission products like cesium were examined and will be reported. Using a two electrode electrochemical cell, the apparent potential and activity coefficient of GdCl3 were studied as a function of concentration of GdCl3 and the influence of cesium on these properties will be reported. Further, relevant phase diagram data were collected and will be presented. The liquidus temperatures for the xGdCl3-CsCl-LiCl-KCl mixtures were determined using a TGA/DSC. Heat capacities (Cp) of these mixtures were also determined using TGA/DSC as a function of concentration of GdCl3, again examining the influence of CsCl on these properties.
