Abstract

Procédé pour retenir des substances radio-actives volatiles formées dans le traitement ultérieur de combustibles nucléaires. On réduit en NO les oxydes d'azote supérieurs provenant de la dissolution 1 et de la dénitration, on absorbe l'iode, on sépare le mélange gazeux obtenu de manière à obtenir une fraction contenant NO et les substances radio-actives volatiles, on ajoute de l'oxygène aux déchets radio-actifs volatils et on retire l'oxygène enrichi en substances radio-actives volatiles, lequel est soumis à un traitement chimique en 12, 13.
