The present invention provides an electrolytic method for simultaneously recovering U and TRU dissolved in molten salt using a liquid metal as an anode and a cathode. An electrolytic method and an electrolytic apparatus for simultaneously recovering U and TRU include an anode crucible containing a liquid metal for anode used as a cathode, an anode crucible containing the liquid metal for anode, a cathode crucible containing the liquid metal for cathode, And a lead wire connecting the liquid metal for the anode and the current supply device, a lead wire connecting the liquid metal for the cathode and the current supply device, and a molten salt including actinium chloride and rare earth chloride. Here, the electrolytic apparatus uses sacrificial anodes instead of liquid metals to increase the concentration of U and TRU in the molten salt and to collect CdCl 2 in the molten salt in the cathode crucible. According to the present embodiments, the TRU / U ratio is greater than 3 during electrodeposition so that U and TRU can be recovered simultaneously at the cathode, and almost all of the CdCl 2 generated at the anode is recovered from the cathode crucible and reused as an electrode. Can be. |
