Abstract: Advances are being made in the design of the annular centrifugal extractor for nuclear fuel reprocessing extraction process studies. The extractors have been built and tested. Twelve stages of this extractor and 50 stages are used to implement the TRPO process for the cleanup of commercial and defense nuclear waste liquids, respectively. Following advances are available: (1) simple way of assembly and disassembly between rotor part and housing part of extractor, ease of manipulator operation; (2) automatic sampling from housing of extractor in hot cell; (3) compact multi-stage housing system; (a) easy interstage link; (5) computer data acquisition and monitoring system of speed.

Key words: Annular centrifugal extractor, Nuclear waste treatment, Hot test, Automatic sampling
