Description
Comparative study on the electrochemical reduction of uranium oxides in LiCl-Li2O molten salt was carried out for the development of advanced spent fuel management technology. The metallization of UO2 and U3O8 occurred at ∼-2.5 V cell potential which is similar to that of Li2O. In this case, the formation of uranium metal may proceed from the chemical reaction of UO2 and U3O8 with Li resulted from electrolytic reduction of Li2O at cathode. U3O8 transformed to UO2 via UO2.25 intermediate in the conditions of 650 .deg. C reaction temperature, LiCl-Li2O molten salt and Ar gas atmosphere overcoming thermodynamic barrier. These results elucidated the reasons of similar behaviors of UO2 and U3O8 in electrochemical reduction process
