Abstract
The behavior of uranium and fission product simulators in the processing of model spent nuclear fuel in weakly acidic iron(III) nitrate solutions in the presence of supercritical CO2 containing tributyl phosphate (TBP) has been studied. It has been shown that these conditions provide extraction of uranium from iron oxide solution with simultaneous separation of it from existing fission products. The separation of uranium from the TBP phase is performed via its reextraction with an aqueous solution containing hydrogen peroxide and simultaneous reprecipitation in the form of a peroxide. In this case, a high degree of uranium purification from all the fission products is attained, thus allowing it to be reused in a nuclear fuel cycle.
