Abstract

a. Procédé pour chasser l'hexafluorure d'uranium à haute teneur en U-235 des bouteilles servant à son transport par chauffage dans un récipient à ce destiné. b. Le procédé est caractérisé en ce qu'on utilise comme agent de transmission du chauffage des liquides organiques halogénés exempts d'hydrogène. c. Ce procédé évite les risques d'incidents critiques que pourraient provoquer le chauffage électrique direct par surchauffe, ou l'usage de l'eau pour la transmission de la chaleur, cette eau pouvant agir comme modérateur.
