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.
