Advanced designs of used nuclear fuel recycling processes and radioactive waste treatment processes are expected to include more ambitious goals for aqueous based separations including; higher separations efficiency, high-level waste minimization, and a greater focus on continuous processes to minimize cost and footprint. Therefore, annular centrifugal contactors are destined to play a more important role for such future processing schemes. Pilot-scale testing will be an integral part of development of many of these processes. An advanced design for remote maintenance of pilot-scale centrifugal contactors has been developed and a prototype module fabricated and tested for a commercially available pilot-scale centrifugal contactor (CINC V-02, 5-cm rotor diameter). Advanced design features include air actuated clamps for holding the motor-rotor assembly in place, an integral electrical connection, upper flange o-rings, a welded bottom plate, a lifting bale, and guide pins. These design features will allow for rapid replacement of the motor rotor assembly, which can be accomplished while maintaining process equilibrium. Hydraulic testing of a three-stage prototype unit was also performed to verify that design changes did not impact performance of the centrifugal contactors. Details of the pilot-scale remote maintenance design, results of testing in a remote mockup test facility, and results of hydraulic testing of the advanced design are provided.
