Dicyclohexano-18-crown-6 ether: a new selective extractant for nuclear fuel reprocessing

Abstract

Isomers of dicyclohexano-18-crown-6 ether (DCH 18C6) are used as a selective extradant of plutonium contained in high and medium activity solutions of nuclear fuel reprocessing; this extractant exhibits both higher stability and better selectivity towards plutonium separation than the tributyl phosphate used in the Purex process.
