[en] The United States Department of Energy's Advanced Fuel Cycle Initiative (AFCI) is performing research and development activities to enable future recycle of used nuclear fuel. Critical elements of this program include development and demonstration of used fuel separation technologies and suitable waste forms. The AFCI program is currently developing aqueous and electrochemical separation technologies, to provide technical options for recycle of used fuel into LWR and fast reactors. Waste forms are being developed to immobilize the waste fractions resulting from the separations processes. Program emphasis has recently focused on development of technologies that are cost effective and implementable at large-scale. An overview of the evolution of the separations and waste form program strategy will be discussed, as well as recent technical accomplishments in the program. (authors)
