Abstract
A process was developed for the extraction and separation of actinides and REEs from PUREX process raffinates using TODGA in meta-nitrobenzotrifluoride (F-3). The flowsheet proposed was tested under dynamic conditions using simulated raffinates of the PUREX process. The process includes joint extraction of actinides and REEs, nitric acid scrubbing, actinide stripping, and REE stripping. The conditions of selective stripping of minor actinides with a DTPA solution in the presence of a salting-out agent were determined.
