Editing Nuclear reprocessing (section)

=====SANEX=====
'''S'''elective '''A'''cti'''N'''ide '''EX'''traction. As part of the management of minor actinides it has been proposed that the [[lanthanide]]s and trivalent minor [[actinide]]s should be removed from the PUREX [[raffinate]] by a process such as DIAMEX or TRUEX. To allow the actinides such as americium to be either reused in industrial sources or used as fuel, the lanthanides must be removed. The lanthanides have large neutron cross sections and hence they would poison a neutron driven nuclear reaction. To date the extraction system for the SANEX process has not been defined, but currently several different research groups are working towards a process. For instance the French [[Commissariat à l'énergie atomique|CEA]] is working on a [[bis-triazinyl pyridine]] (BTP) based process.<ref><!-- These preprints need to be replaced with appropriate peer-reviewed articles. -->C.

Other systems such as the dithiophosphinic acids are being worked on by some other workers.
