Title (EN) METHOD FOR SEPARATING ISOTOPES
(FR) METHODE DE SEPARATION ISOTOPIQUE
Abstract:
(EN) The present invention utilizes a vortex tube for separating the isotopes. A gas mixture containing the isotopic molecules, with or without a carrier gas, enters the vortex tube under pressure and is separated into a hot discharge flow stream and a cold discharge flow stream. The hot discharge is enriched in lighter isotopic molecules whereas the cold discharge flow stream is enriched in the heavier isotopic molecules. The vortex tube can be used in a single stage or multistage isotope separation apparatus. An electromagnetic beam may be used in conjunction with one or more vortex tubes to selectively and simultaneously excite the vibrational mode of other than the major isotopic components.
(FR) Un tube vortex (12) est utilise pour la separation d"isotopes. Un melange gazeux (22) contenant les molecules isotopiques, avec ou sans gaz porteur, entre dans le tube (12) sous pression et est separe en un courant de decharge chaud (a travers 34) et en un courant de decharge froid (a travers 20 ou 40). Le courant de decharge chaud est enrichi en molecules isotopiques legeres (voir le haut de la figure 1) tandis que le courant de decharge froid est enrichi en molecules isotopiques lourdes (voir le bas de la figure 1). Le tube vortex (12) peut etre utilise dans un appareil de separation d"isotopes a un seul etage ou a plusieurs etages. Un faisceau electromagnetique (44) peut etre utilise en association avec un ou plusieurs tubes vortex (12) pour exciter de maniere selective et simultanee le mode vibratoire de composants autre que les composants isotopiques principaux.
