Abstract

Procédé de fabrication de poudre d'oxyde d'uranium à partir d'UF6 qui consite à convertir UF6 en UO2F2 en le faisant réagir avec un excès d'alcool en phase gazeuse, puis convertir l'UO2F2 formé en oxyde d'uranium, en soumettant l'hydrocarbure formé dans cette réaction en phase gazeuse et cet excès d'alcool à une combustion avec un gaz oxygéné chargé séparément.
