Abstract
The method for processing a mixture of air and rare gases consisting especially of xenon and krypton which are at least partially radioactive and especially for processing gaseous effluents arising from the reprocessing of irradiated fuels comprises a step involving concentration of the rare gases in solution in liquid argon by cryogenic distillation of the light gases and mainly nitrogen from the liquefied mixture.
