Title: Experimental Study of Codeposition Electrochemistry Using Mixtures of ScCl 3 and YCl 3 in LiCl-KCl Eutectic Salt at 500°C

Abstract

Cyclic voltammetry and chronopotentiometry tests were applied to molten LiCl-KCl eutectic at 500 °C including amounts of ScCl 3 and YCl 3. The purpose of the testing was to observe the effect of applied electrical current on the codeposition of scandium and yttrium, which were chosen as surrogate elements for uranium and plutonium, respectively. Features of the work were to vary the concentration of ScCl 3 (at relatively low concentrations) as well as varying the applied current, all with a fixed concentration of YCl 3. Results of the experiments could provide insight of uranium electrorefining and may provide evidence, which suggests the electrorefiner could be operated at lower UCl 3 concentration whereby codeposition (U and Pu) could be more effectively controlled.
