ABSTRACT:
Process for the treatment of a metal alloy based on uranium, generally in highly enriched form and other metallic elements, comprising a fluorination treatment with the aid of at least one fluorine-containing gas, optionally with an intermediate fluorination with the aid of a fluoric compound, a distillation treatment of the gaseous fluoride flow obtained in order to obtain pure uranium hexafluoride, as well as a mixing treatment of said hexafluoride with another more depleted hexafluoride to obtain the desired final isotopic content.
