Abstract

Abstract In the frame of development of improvements of current liquid–liquid extraction technologies for reprocessing spent nuclear fuel, and for development of effective schemes of HLW treatment, novel methods of recovery and separation of uranium, transuranium and rare-earth elements have been proposed. The methods of solvent-free extraction in supercritical CO 2, countercurrent chromatography, and sorption by fibrous “filled” sorbents are discussed.
