001008576 520__ $$aThe recycling of Americium is considered a viable option for future extended nuclear fuel cycles. How-ever, the separation of Am(III) from Cm(III) and trivalent lanthanides contained in used nuclear fuel is still one  of  the  most  difficult  challenges  in  element  separations,  and  only  few  examples  of  selective Am(III) separation exist to date (e.g., EXAm).[1] Within the course of recent European collaborative pro-jects, a  chemical  system  was  developed  making  use  of  the opposite  selectivity  of  the  well-known TODGA (N,N,N',N'-tetraoctyldiglycolamide, Figure 1) extractant and the hydrophilic sulphonated SO3-Ph-BTBP   (sodium   3,3’,3’’,3’’’-([2,2’-bipyridine]-6,6’-diylbis(1,2,4-triazine-3,5,6-triyl))-tetrabenzenesul-fonate, Figure 1). This so-called AmSEL process was developed to selectively strip Am(III) from a loaded TODGA  solvent  containing  Am,  Cm  and  trivalent  lanthanides.[2]  Stripping  kinetics  were  measured  in  single centrifugal contactors and a flow-sheet is currently under development using the French PAREX code.[3] This presentation will highlight the development of the AmSEL process and discuss the current flow-sheet. A process demonstration in our 16-stage centrifugal contactor setup is planned soon.Funding for this research was provided by the European Commission through the GEN IV Integrated Oxide Fuels Recycling Strategies (GENIORS) project, grant agreement number 730227 and the Parti-tioning  And  Transmuter  Research  Initiative  in  a  Collaborative  Innovation  Action  (PATRICIA)  project,  grant agreement number 945077.
