ABSTRACT
Conversion from high-enriched uranium (HEU) to
low-enriched uranium (LEU) targets for the Mo-99
production requires certain modifications of the target
design, the digestion and the purification processes.
ANL and the Argentine Comisión Nacional de Energía
Atómica (CNEA) are collaborating to overcome all the
concerns caused by the conversion of the CNEA process to
use LEU foil targets. A new digester with stirring
system has been successfully applied for the digestion
of the low burn-up U foil targets in KMnO4 alkaline
media. In this paper, we report the progress on the
development of the digestion procedure utilizing
effective stirring and focusing on minimization of the
liquid radioactive waste.
