Abstract
1517071 Isotope separation using irradiation KRAFTWERK UNION AG 21 April 1976 [22 April 1975] 16228/76 Heading C1A At least one isotopic component is separated from a gaseous or vapourous isotopic mixture in a two stage irradiation process comprising (a) irradiating the mixture to photochemically transform the mixture, (b) irradiating the transformed mixture whilst still in gas or vapour form with a radiation of a frequency chosen to selectively excite the component(s) which are to be separated from the mixture, these excited molecules then react selectively with a co-reactant and the reaction product formed is separated from the resulting isotopic mixture by known methods. The separation of uranium 235 and 238 hexafluoride isotopes is exemplified, thus in the first irradiation stage either (i) UF 6 + hv 1 # UF 5 + F the fluorine atoms being reacted with a capturing reagent added to the system or (ii) UF 6 + R + hv 1 ¼ UF 5 + FR where R is a coreactant added to the system and in the second irradiation stage either dissociation occurs followed by combination with the coreactant R’ UF 5 + hv 2 # UF 4 + F or the coreactant reacts with the excited molecule UF 5 + hv 2 # UF 5 and UF 5 ‘ + R’ # UF 4 + FR’
