[en] The principal immediate objective is the conversion of minor actinides (Pa, Np, Am, Cm and transcurium elements) either to fission products or to major actinides (Th, U and Pu) in a reactor. Various extractants have been suggested for recovery of an Am/Cm/rare earth fraction from the HLW. The most promising seem to be a neutral, bi-functional organophosphorus extractant capable of operating directly on the HLW, and dibutyl butylphosphonate acting on the HLW after acidity reduction and addition of a salting agent (probably aluminium nitrate). For the subsequent separation of Am/Cm from the rare earths there is at present virtually only one possibility, viz. the use of diethylenetriamine-penta-acetate (DTPA) or a related compound, despite certain draw-backs. A preliminary 'exhaustive extraction' for residual U, Np and Pu may precede Am/Cm recovery. Another possible preliminary step is an oxalate precipitation and dissolution cycle. Much development is required before a complete separation flowsheet can be written, and the feasibility (or otherwise) of the separations can be established
