Development on reprocessing technologies for FBR spent fuel including chemical flowsheet and centrifugal contactor was conducted. The flowsheet is based on single cycle extraction without Pu partitioning and products purification cycles, and confirmed that high recovery of U, Pu and Np as well as moderate decontamination of fission products. Durable contactor with magnetic bearings have established by tests of 4 years - continuous operation and of irradiation which dose corresponded to 10 years use. A design study showed a sketch of a future FBR fuel reprocessing plant.
