Title: USE OF HYDROXY-IMINE ALKANOIC ACIDS AS ANTI-NITROUS AGENTS IN OPERATIONS OF REDUCTIVE BACK-EXTRACTION OF PLUTONIUM
Abstract:
The invention relates to the use of hydroxy-imine alkanoic acids including at least four carbon atoms as anti-nitrous agents in operations of reductive back-extraction of plutonium. The invention may be useful in any method for reprocessing spent nuclear fuel that includes one or more operations of reductive back-extraction of plutonium and, more particularly, in the PUREX method as implemented in modern nuclear fuel reprocessing plants, as well as in processes derived therefrom.
