Abstract: | Centrifugal contactors have many advantages and are favored for reprocessing of spent nuclear fuel and partitioning of high-level waste. A new ?20 mm annular centrifugal contactor for laboratory scale has been developed for the hot test of the total TRPO process. A modular design, a multi-stage group housing design and ceramic bearings are adopted in the new centrifugal contactor. A sampling system and a rotor speed acquisition and monitoring system for ?20 mm annular centrifugal contactors have been developed for tests in the hot cell. The hydraulic performance of both a single-stage centrifugal contactor and a three-stage cascade has been studied. The nominal throughput of the single-stage centrifugal contactor can reach 13.5 l/h under suitable operation conditions for H2O–kerosene system. The hydraulic performance of the three-stage cascade is also good. |
