Abstract

This study proposed a new electrolytic reduction technology that is based on the integration of simultaneous uranium oxide metallization and LiO electrowinning. In this electrolytic reduction reaction, electrolytically reduced Li deposits on cathode and simultaneously reacts with uranium oxides to produce uranium metal showing more than 99% conversion. For the verification of process feasibility, the experiments to obtain basic data on the metallization of uranium oxide, investigation of reaction mechanism, the characteristics of closed recycle of LiO and mass transfer were carried out. This evolutionary electrolytic reduction technology would give benefits over the conventional Li-reduction process improving economic viability such as: avoidance of handling of chemically active Li-LiCl molten salt increase of metallization yield, and simplification of process.

Key Words : Electrolytic Reduction Technology, Uranium Oxide, Uranium Metal, Lithium Chloride, Molten Salt, 전기화학적 금속전환기술, 우라늄 산화물, 우라늄 금속, 염화리튬, 용융염
