Uranium Isotope Enrichment by Chemical Method

Through basic research on the separation of uranium isotopes by the isotopic equilibrium reaction of uranus and uranyl ions, we discovered that a novel redox chromatography in adsorption columns is most efficient for the enrichment of ²³⁵U. Further studies of kinetics and multicomplexes led to the formation of two very important equations that satisfactorily predict the degree of separation of uranium isotopes. Some results from extensive single-and multicolumn experiments and a model plant currently under design for recovery of 3% enriched uranium are also described.
