Radiochemistry Aims and scope

Abstract

Refining of uranyl nitrate solutions in centrifugal extractors to remove restricted impurities was studied. The maximum solvent loading with uranium in the steps of extraction, scrubbing, and stripping and the decontamination factors from the restricted impurities were determined. The optimum ratio of the flows of the aqueous and organic phases in scrubbing of the recycled solvent was found.
