Purexn.

Brit.

/ˈpjʊərɛks/,

/ˈpjɔːrɛks/, U.S.

/ˈp(j)ʊˌrɛks/

Forms: 1900s– PUREX, 1900s– Purex.

Origin: Probably formed within English, as an acronym. Etymon: English plutonium uranium extraction.

Etymology: Probably an acronym < the initial letters of plutonium uranium extraction.Alternative suggestions for the underlying phrase include ‘plutonium uranium recovery by extraction’ and ‘plutonium uranium reduction extraction’.

An industrial process for separating the plutonium and uranium from spent uranium fuel by using tri-n-butyl phosphate as a solvent. Also Purex process. Usually attributive.
