Title
(EN) PRODUCING HALOGENATED PRODUCTS FROM METAL HALIDE FEEDS
(FR) FABRICATION DE PRODUITS HALOGENES A PARTIR DE CHARGES AUX IODURES METALLIQUES
Abstract
(EN)
A method and apparatus producing halogenated products from metal halide feeds. In one embodiment, uranium hexafluoride is treated by separating fluorine from the metal of the uranium hexafluoride. Uranium hexafluoride is introduced into a molten metal bath under conditions whereby the uranium hexafluoride in the presence of hydrogen and oxygen can react to form a uranium dioxide an anhydrous hydrogen fluoride. The anhydrous hydrogen fluoride is removed from the molten metal bath as a gas stream and the uranium dioxide is discharged as a ceramic phase.

L'invention se rapporte à un procédé et à un dispositif permettant de fabriquer des produits halogénés à partir de charges aux iodures métalliques. Dans une variante, on traite l'hexafluorure d'uranium en séparant le fluor du métal de cet hexafluorure. Ensuite, on introduit l'hexafluorure d'uranium dans un bain de métal en fusion, dans des conditions telles que l'hexafluorure d'uranium en présence d'hydrogène et d'oxygène peut réagir et former un dioxyde d'uranium et un fluorure d'hydrogène anhydre. Le fluorure d'hydrogène anhydre est extrait du bain de métal en fusion sous la forme d'un flux gazeux et le dioxyde d'uranium est évacué en phase céramique.
