Abstract

L'invention concerne un procédé pour convertir en continu de l'hexafluorure d'uranium en bioxyde d'uranium dans un système comprenant quatre réacteurs à lits fluidisé. Dans le premier réacteur, on fait réagir un mélange de UF6 et de vapeur. Le produit solide de cette première réaction comprenant UO2 F2 et U3 O 8 est envoyé dans le deuxième réacteur, dans lequel il réagit avec de la vapeur et de l'hydrogène. Le produit de la deuxième réaction comprenant du UO2 est envoye dans le troisième réacteur dans lequel il réagit avec de la vapeur et de l'hydrogène en proportions bien déterminées. Le troisième produit de réaction intermédiaire ainsi obtenu comprenant essentiellement du UO2 est dirigé vers un quatrième réacteur dans lequel il entre en réaction avec un mélange d'air et d'azote. Application à la production de bioxyde d'uranium de qualité céramique, utilisable pour fabriquer des pastilles combustibles pour réacteurs nucléaires.
