Thermodynamics of La and U and the separation factor of U/La in fused Me(Ga-40Â wt.% In)/3LiCl-2KCl system

Separation of lanthanides and actinides can be achieved in a unique “molten chloride - liquid metal” system. Electrode potentials were recorded vs. Cl−/Cl2 reference electrode and the temperature dependencies of the apparent standard potentials of La-(Ga-In) and U-(Ga-In) alloys were determined. Thermodynamic properties and separation factor of lanthanum and uranium were calculated. The obtained data show the perspective for using this system in future innovation method for recovery of nuclear waste.
