Abstract: The Chalmers Grouped ActiNide EXtraction process is a solvent extraction process for the homogeneous recycling of spentnuclear fuel. The use of TBP for the extraction of tetra- and hexavalent actinides can be problematic for several reasons,including troublesome degradation products causing crud formation, decreased extraction yield and the possibility of explosivered oil reactions. Here, the substitution of TBP by a N,N-dialkyl monoamide, DEHBA, is investigated. The findingssuggest that DEHBA can be a suitable extracting agent for use in the CHALMEX solvent, although identified drawbacksneed to be further investigated.
