This paper summarizes progress at three collaborating U.S. national laboratories on the extraction of the fission products 99Tc and 137Cs from alkaline high-level wastes. Efficient economical processes for Tc and Cs extraction (SRTALK and alkaline-side CSEX, respectively) have been developed, and testing has progressed through batch tests on actual wastes and continuous counter-current centrifugal-contactor tests on simulants.
