| Abstract: | For the first time, the possibility of dissolution of spent nuclear fuel from a nuclear power plant in liquid and supercritical carbon dioxide was demonstrated. As shown by the example of spent nuclear fuel, the dissolution and the extraction of actinides and fission products by solutions of tributyl phosphate and nitric acid adducts TBP(HNO3)1.8 in carbon dioxide can be used as one of the stages of spent nuclear fuel reprocessing. |
