N1 - The authors would like to acknowledge the financial support of the European Commission in the projects: NEWPART (FI4I-CT96-0010), PARTNEW (FIKW-CT2000-00087), EUROPART (F16W-CT-2003-508854) and ACSEPT (FP7-CP-2007-211267), as well as the financial support of the German Federal Ministry of Education and Research (BMBF, Contract No. 02NUK012E). This work is dedicated to the memory of Charles Madic for his strong scientific support during the coordination of the European projects.
AB - The selective partitioning (P) of long-lived minor actinides from highly active waste solutions and their transmutation (T) to short-lived or stable isotopes by nuclear reactions will reduce the long-term hazard of the high-level waste and significantly shorten the time needed to ensure their safe confinement in a repository. The present paper summarizes the on-going research activities at Forschungszentrum Julich (FZJ), Karlsruher Institut fur Technologie (KIT) and Institute for Transuranium Elements (ITU) in the field of actinide partitioning using innovative solvent extraction processes. European research over the last few decades, i.e. in the NEWPART, PARTNEW and EUROPART programmes, has resulted in the development of multi-cycle processes for minor actinide partitioning. These multi-cycle processes are based on the co-separation of trivalent actinides and lanthanides (e.g. by the DIAMEX process), followed by the subsequent actinide(III)/lanthanide(III) group separation in the SANEX: process. The current direction of research for the development of innovative processes within the recent European ACSEPT project is discussed additionally.This paper is focused on the development of flow-sheets for recovery of americium and curium from highly active waste solutions. The flow-sheets are verified by demonstration processes, in centrifugal contactors, using synthetic or genuine fuel solutions. The feasibility of the processes is also discussed.
