Radioactive isotopes Cs-137 and Sr-90, two significant fission products that are usually carried into High Level Waste (HLW) during spent nuclear fuel reprocessing are suggested to be removed from HLW in order to reduce the volume of HLW and then make nuclear energy more clean and sustainable. A variety of separation techniques, including solvent extraction, have been developed for the removal of Cs-137 and Sr-90 from HLW. Among those developed separation techniques, solvent extraction is more applicable and promising, particularly for acidic HLW. This article reviews the scientific progress as well as application developments of the solvent extraction method for the separation of strontium and cesium from HLW in the last decade.
