Abstract

Procedimiento para producir composiciones ricas en dióxido de uranio a partir de hexafluoruro de uranio en una zona de reacción, en presencia de una llama activa, caracterizado por las etapas de: (a) introducir una primera mezcla gaseosa reactiva comprendiendo hexafluoruro de uranio y un gas portador conteniendo oxígeno dentro de la zona de reacción, (b) introducir separadamente, como segundo reactivo gaseoso, un gas reductor, dentro de la zona de reacción, (c) separar temporalmente dicho primer reactivo gaseoso del citado segundo reactivo gaseoso con un gas protector, que temporalmente evita un mezclado sustancial y una reacción entre dichos reactivos gaseosos primero y segundo.
