abstract = {Americium is the main contributor to the
longtermradiotoxicity and to the heat generation of
glassesused for HLW conditioning. To decrease these
impactsand to avoid the difficult recycling of curium, the
selectiveseparation and recovery of a pure americium
productdirectly from PUREX raffinate is envisaged in this
study.The new approach is based on the co-extraction
oflanthanide(III) and actinide(III) cations from a
PUREXraffinate into an organic phase containing
N,N,N’,N’-tetraoctyl-diglycolamide (TODGA) as
extractant,followed by the subsequent selective stripping of
Am(III)and separation from Cm(III) and lanthanides.
Threewater-soluble selective ligands were studied:
H4TPAENdeveloped at the CEA Marcoule, TS-BTPhen developed
atthe University of Reading, and SO3-Ph-BTBP developedat
KIT. Very promising results were achieved for allsystems
with a quite high Cm(III)/Am(III) selectivitybetween 3-4 to
carry out the difficult separation atreasonably high process
relevant nitric acid acidities.Numerous batch experimental
data were acquired for thedevelopment of the extraction
model. Finally, tests onsingle centrifugal contactors were
conducted to getinformation on the kinetic and hydraulic
performance ofthe system. Finally, tests on single
