Abstract

Procédé de purification de gaz contenant des substances radioactives et provenant du traitement ultérieur de combustibles nucléaires usés. On mélange les gaz contenant les substances radioactives avec un gaz porteur dont le comportement de séparation est à peu près identique à celui des substances radioactives, on sépare les gaz contenant le gaz porteur, par distillation dans la colonne 7, en une fraction contenant les substances radioactives et le gaz porteur et une fraction privée de ces substances et on sépare le gaz porteur des substances radioactives.
