(FR) PROCEDE DE PREPARATION D'UN OXYCHLORURE ET/OU OXYDE D ' ACTINIDE ( S ) ET/OU DE LANTHANIDE (S) A PARTIR D'UN MILIEU COMPRENANT AU MOINS UN SEL FONDU
Abstract
(EN) The invention relates to a process for manufacturing an oxychloride or oxide of actinide(s) and/or of lanthanide(s) from a chloride of actinide(s) and/or of lanthanide(s) present in a medium comprising at least one molten salt of chloride type comprising a step of bringing said chloride of actinide(s) and/or lanthanide(s) present in said medium comprising at least one molten salt of chloride type into contact with a wet inert gas.
(FR) L'invention a trait à un procédé de fabrication d'un oxychlorure ou oxyde d'actinide(s) et/ou de lanthanide(s) à partir d'un chlorure d'actinide(s) et/ou de lanthanide(s) présent dans un milieu comprenant au moins un sel fondu du type chlorure comprenant une étape de mise en contact dudit chlorure d'actinide(s) et/ou lanthanide(s) présent dans ledit milieu comprenant au moins un sel fondu du type chlorure avec un gaz neutre humide.
