AbstractAbstract
[en] Technetium has been neglected for a long time in reprocessing nuclear fuels, but recent studies have emphasized its anomalous behaviour: it is fairly extracted by TBP and it catalyses hydrazine decomposition by nitric acid. With today's increased burn-up fuels a low technetium decontamination factor is expected and reoxidation risks are enhanced in the uranium-plutonium partition. This paper deals with an examination of technetium behaviour and an attempt to limit the risks using slight modifications of the flowsheets
