Title
(EN) PROCESSING OF URANIUM MATERIALS BY FLUORINATION AND DISSOCIATION OF URANIUM HEXAFLUORIDE IN PLASMA SEPARATOR
(FR) PERFECTIONNEMENTS PORTANT SUR LE TRAITEMENT DE MATIERES
Abstract
(EN)
The invention provides a series of techniques for processing uranium containing feed materials such as uranium ores, reprocessed uranium, uranium containing residues and uranium containing spent fuel. The processes described involve fluorination (2) of uranium containing material (8, 24, 26), separation (14) of the uranium containing material (20, 22) from other materials based on ionisation thereof with the non-ionised fluorine containing material being recycled (16). Metallic uranium and/or plutonium and/or fission products may result. The technique offers advantages in terms of the range of materials which can be reprocessed and a reduction in the number of complexity of stages which are involved in the process.
(FR)
L'invention concerne un ensemble de techniques de traitement de matières constituant une alimentation contenant de l'uranium, telles que des minerais d'uranium, de l'uranium retraité, des résidus contenant de l'uranium ainsi qu'un combustible épuisé contenant de l'uranium. Les procédés décrits impliquent la fluoruration de la matière contenant de l'uranium, la séparation de la matière contenant l'uranium, à partir d'autres matières, en fonction de l'ionisation de ces matières à l'aide de la matière contenant du fluor non ionisé, en cours de recyclage. On peut ainsi obtenir de l'uranium métallique et/ou du plutonium et/ou des produits de fission. Cette technique présente l'avantage en terme de l'éventail de matières à retraiter, ainsi qu'une diminution du nombre d'étapes complexes impliquées dans le procédé.
