PURPOSE: An electrolytic method for collecting uranium (U) and trans-uranium (TRU) at the same time is provided to separately use liquid cadmium as positive and negative electrodes for maintaining a TRU/U ratio in molten salt to be greater than three. CONSTITUTION: An electrolytic apparatus for collecting uranium (U) and trans-uranium (TRU) at the same time includes a positive electrode crucible (4), a negative electrode crucible (5), a positive electrode lead line (6), a negative electrode lead line (7), molten salt (8), and a sacrificial positive electrode. The positive electrode crucible contains liquid metal for a positive electrode (2), and the negative electrode crucible contains liquid metal for a negative electrode (3). The molten salt contains actinide group chloride and rare earth group chloride. The sacrificial positive electrode is used for collecting CdCl2 included in the molten salt. An electrolytic method for collecting U and TRU comprises the following steps: collecting in the molten salt using the positive and negative electrodes formed of liquid metal; finishing electrodeposition when the electric potential for the electrodeposition in the negative electrode reaches the reference potential; and mounting the sacrificial positive electrode after changing the positive electrode into a second negative electrode, and collecting Cd from the molten salt using the second negative electrode. |
