A simple and robust method was developed for the chemical separation of uranium and plutonium from mixed U/Pu/fission product solutions. The method is based on a commercially available resin, UTEVA-spec. It yields pure U and Pu fractions with recoveries superior to 95% respectively, using a single column. The method is simple and robust, allowing a rapid separation with a minimum of secondary waste being created. The method was validated for application in routine analysis of nuclear materials covering a wide range of concentrations and U/Pu ratios.
