ABSTRACT:
For the first time the apparent standard potentials of the alloys of uranium and lanthanoids (La,Nd) in the Ga-In/ 3LiCl-2KCl low-melting system in the temperature range from 723 to 823 K were measured by potentiometry technique at zero current . The separation coefficients of actinide and lanthanoids were calculated. The results obtained testify that processes for the U and rare-earth metals separation in chloride melts with the use of the liquid bimetallic electrodes based on gallium are perspective for reprocessing the spent nuclear fuel.
