| 简介 |
The present invention relates to a method for collecting uranium and transuranium alloys, the method comprising the steps of : (a) preparing an electrolytic bath in which an inert positive electrode and a liquid negative electrode are immersed in molten salts including ions of uranium (U), transuranium (TRU), and rare earth elements (RE), electrochemically co-depositing the U, TRU, and RE in the liquid negative electrode, and generating molten residual salts; (b) collecting the liquid negative electrode, in which the U, TRU, and RE are co-deposited, from the electrolytic bath, and then distilling the liquid negative electrode to collect U, TRU, and RE solids; (c) immersing the U, TRU, and RE solid positive and negative electrodes collected in the step (b) in the molten residual salts generated in the step (a), and then electrochemically dissolving RE selectively to generate a solid positive electrode in which RE is reduced; and (d) discharging the solid positive electrode in which the RE is reduced in the step (c), and then distilling the solid positive electrode to collect U and TRU alloys.(S10) Electrochemically co-deposit the U, TRU, and RE in the liquid negative electrode, and generate molten residual salts(S20) Collect the liquid negative electrode, in which the U, TRU, and RE are co-deposited, from the electrolytic bath, and then distill the liquid negative electrode to collect U, TRU, and RE solids(S30) Electrochemically dissolve RE selectively in the U, TRU, and RE solid positive electrode(S40) Collect U and TRU by distilling a solid positive electrode in which the RE is reduced(S50) Distill a negative electrode attached with the RE, and separately collect RE solidsCOPYRIGHT KIPO 2019 |
