To develop processing of fuel debris, selective fluorination and molten salt electrolysis have been proposed as separating uranium and plutonium. We have investigated electrochemical behavior of zirconium in molten LiCl-KCl-Li2O-ZrF4. As a result, reduction current of zirconium decreased and shape variation of voltammogram depending on concentration of Li2O could be observed.
