Abstract
The UP3 reprocessing plant commissioned for active operation in November 1989 features numerous innovations both for the process flowsheet and the associated equipment. These innovations yielded positive results following initial active testing and are of considerable interest for solvent extraction specialists. This paper describes the main improvements introduced for the extraction cycles used to separate and purify uranium and plutonium. Specifically, these improvements include: adaptation of the first extraction cycle flowsheet for technetium decontamination and tritium confinement; solvent purification process based on distillation, a key element in the solvent system; flowsheets adapted for maximum recycling of liquid organic and mineral streams (solvent or nitric acid); use of annular or cylindrical pulsed columns with high-efficiency packing.
