Behaviour of palladium in the Purex process

Description

Palladium is an abundant fission product but a minor radioactive contaminant of nuclear fuels. Its peculiar chemical behaviour is troublesome because it reacts with most of the reagents used in partition and forms insoluble compounds or cruds. Fortunately palladium extraction by 30% TBP-dodecane is moderate and high DF are expected as long as the diluent is not excessively degraded. However, γ irradiated diluents display strong complexing power for palladium and retention of this element is observed. (author)
