Abstract

L'INVENTION CONCERNE UN PROCEDE DE SEPARATION D'ISOTOPES D'UN ELEMENT SUIVANT LE BREVET PRINCIPAL. LE PROCEDE CONSISTE A VAPORISER DES COMPOSES VOLATILS PAR EXEMPLE D'URANYLE, AYANT UN SPECTRE D'ABSORPTION INFRAROUGE A DEPLACEMENT ISOTOPIQUE ASSOCIE A L'ELEMENT QUI DOIT ETRE SEPARE, PUIS A IRRADIER CE COMPOSE AVEC UNE RADIATION INFRAROUGE QUI EST ABSORBEE PREFERENTIELLEMENT PAR UNE VIBRATION MOLECULAIRE DES MOLECULES DU COMPOSE CONTENANT UN ISOTOPE PREDETERMINE DUDIT ELEMENT, DE MANIERE QUE DES MOLECULES EXCITEES DU COMPOSE SOIENT PRODUITES ET ENRICHIES EN LES MOLECULES DU COMPOSE RENFERMANT LEDIT ISOTOPE PREDETERMINE, DE MANIERE A PERMETTRE LA SEPARATION DE CES MOLECULES EXCITEES PAR IRRADIATION DANS DES CONDITIONS DANS LESQUELLES LES MOLECULES EXCITEES SONT DISSOCIEES, ET A SEPARER EGALEMENT LES MOLECULES EXCITEES DANS UNE ETAPE DISTINCTE DE SEPARATION. CETTE ETAPE CONSISTE A IRRADIER LES MOLECULES EXCITEES PAR UN LASER UV VISIBLE OU PAR UN SECOND LASER INFRAROUGE EN VUE DE TRANSFORMER LES MOLECULES EXCITEES EN UN PRODUIT SEPARABLE, OU AUSSI PAR TRANSFORMATION CHIMIQUE DES MOLECULES EXCITEES, DE PREFERENCE PAR REACTION AVEC UN CORPS REACTIONNEL GAZEUX. APPLICATION NOTAMMENT A LA SEPARATION DES ISOTOPES DE L'URANIUM.THE INVENTION RELATES TO A PROCESS FOR SEPARATING ISOTOPES FROM AN ELEMENT FOLLOWING THE MAIN PATENT. THE PROCESS CONSISTS OF VAPORIZING VOLATILE COMPOUNDS, FOR EXAMPLE URANYL, HAVING AN INFRARED ABSORPTION SPECTRUM WITH ISOTOPIC DISPLACEMENT ASSOCIATED WITH THE ELEMENT WHICH MUST BE SEPARATE, THEN IN IRRADIER THIS COMPOUND WITH AN INFRARED RADIATION BY PRE VIFER ABSORBATION. MOLECULAR OF THE MOLECULES OF THE COMPOUND CONTAINING A PREDETERMINED ISOTOPE OF THE SAID ELEMENT, SO THAT EXCITED MOLECULES OF THE COMPOUND ARE PRODUCED AND ENRICHED WITH THE MOLECULES OF THE COMPOUND CONTAINING A PREDETERMINED ISOTOPE OF THE SAID ELEMENT, SO AS TO ALLOW THE EXCITEMENT OF SEPARATION UNDER THESE CONDITIONS OF SEPARATION. WHICH THE EXCITED MOLECULES ARE DISSOCIATED, AND ALSO SEPARATE THE EXCITED MOLECULES IN A SEPARATE STEP OF SEPARATION. THIS STEP CONSISTS OF IRRADIING THE MOLECULES EXCITED BY A VISIBLE UV LASER OR BY A SECOND INFRARED LASER WITH A VIEW OF TRANSFORMING THE EXCITED MOLECULES INTO A SEPARABLE PRODUCT, OR ALSO BY CHEMICAL TRANSFORMATION OF THE EXCITED MOLECULES, PREFERABLY BY REACTION WITH BODY-REACTION. APPLICATION IN PARTICULAR TO THE SEPARATION OF ISOTOPES OF URANIUM.
