Abstract

Le procédé selon l'invention consiste à faire circuler à une vitesse supersonique le gaz d'alimentation à travers une tuyère de détente 13 dans des conditions d'écoulement pour lesquelles la détente du gaz d'alimentation à la vitesse supersonique provoque la condensation du gaz quand celui-ci n'est pas excité vibrationnellement, et l'irradiation de ce gaz s'écoulant à la vitesse supersonique par la radiation d'un laser excitant sélectivement les molécules du gaz d'alimentation contenant un isotope particulier, afin d'inhiber la condensation de ces molécules pour leur séparation aérodynamique en un courant enrichi 22 et un courant appauvri 23. Un tel procéde convient en particulier pour séparer le **235U du UF6 .The method according to the invention consists in making the feed gas flow at a supersonic speed through an expansion nozzle 13 under flow conditions for which the expansion of the feed gas to supersonic speed causes the gas to condense. when this is not vibrated, and irradiating this gas flowing at supersonic speed by radiation from a laser selectively exciting the molecules of the feed gas containing a particular isotope, in order to inhibit the condensation of these molecules for their aerodynamic separation into an enriched stream 22 and a lean stream 23. Such a process is particularly suitable for separating ** 235U from UF6.
