      abstract     = {Recycling americium from spent nuclear fuel is considered
                      as an important option for a future sustainable nuclear fuel
                      cycle. The PUREX solvent extraction process allows to
                      separate uranium and plutonium from a solution of spent fuel
                      dissolved in nitric acid. In a second step, it would be
                      desirable to separate americium from fission products, and
                      especially lanthanides, but also from curium in order to
                      further transmute americium in future fast neutron reactors.
                      For this purpose, we report the investigation of a new
                      solvent extraction process based on the use of TODGA as an
                      extractant in the organic phase and H4TPAEN as a selective
                      Am(III) stripping agent in the aqueous phase. With this
                      promising system it is possible to co-extract Am, Cm and
                      lanthanides at high acidity and then selectively strip
                      americium from the loaded organic phase at pH around 1 with
                      H4TPAEN. Batch extraction data were acquired to evaluate
                      best conditions to develop a liquid-liquid extraction flow
                      sheet. The influence of several parameters like
                      concentration of ligand, cations and temperature on
                      Am(III)/Cm(III) and Am/lanthanides separation was evaluated.
                      Especially, the ability of H4TPAEN complexing agent to strip
                      macro-concentrations of Am was demonstrated.},
