Theas research is a part of a big European collaboration for developing an advanced recycling strategy for spent nuclear fuel. The Grouped ActiNide EXtraction (GANEX) aims at recycling unfissioned uranium, as well as plutonium and the minor actinides, for transmutation in advanced nuclear reactors. In this way, the amount and volume of the resulting highly active waste is significantly reduced, as is the need for uranium mining. Theas project in specific entails development and process optimisation of the Chalmers GANEX process, which combines the extractants CyMe4-BTBP and tributyl phosphate for the co-extraction of transuranic elements from a spent fuel raffinate.
