      abstract     = {The 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
