ABSTRACT:
Method for separation or enrichment of isotopes bound to anisotopic materials and forming a mixture of isotope compounds by irradiating the mixture of isotope compounds with a first light source to photochemically convert the mixture to a second mixture of isotope compounds, e.g. converting UF.sub.6 to UF.sub.5 and F, irradiating the second mixture in the presence of a reactant with a second light source to selectively excite only one isotope compound of the second mixture, the reactant chemically reacting with the excited compound, e.g. UF.sub.5 .fwdarw.UF.sub.4 + F or UF.sub.5 + R (reactant).fwdarw.UF.sub.4 + RF and separating the reaction products including one of the isotopes of the first mixture.
The separation or enrichment of isotopes may be carried out in apparatus having a highly-reflecting elliptical cylinder with a reaction vessel provided with feed and reactant inlet and reaction products outlet, disposed at one focal line of the elliptical cylinder and a high pressure mercury burner disposed at the second focal line, and with the reaction vessel arranged between resonator mirrors of a dye laser as the second light source.
