Abstract

U chlorination is demonstrated using electrochemical and chemical reactions with ZnCl2 in LiCl–KCl molten salts. Voltammetric studies indicate the instantaneous formation of UCl3 by reaction with ZnCl2, along with the redox reactions of Zn and U–Zn alloys. Chronoamperometry was found effective for indirect monitoring of U chlorination reaction that occurs chemically in the salt. Inductively coupled plasma-optical emission spectroscopy studies confirm the uniform distribution of UCl3 product in the salt, and the electrochemically recovered liquid Zn metal settles at the bottom of the reactor.
