概要

At the Tokai Reprocessing Plant (TRP), spent fuels are dissolved in nitric acid and the dissolved liquid is fed to the extractors (mixer settlers). In the mixer settlers, both uranium and pluton ium are extracted by the solvent that contains tri-butyl phosphate. It is important to control the interface between organic and aqueous phase in the settlers And the interface is controlled by the flow control valve. This valve has maintainability problems because it takes a fair amount of time to maintenance. In addition, this is imported product, the production costs are high, and t he delivery period for this valve is long. Therefore, we have tried to ohtain same type of valves with the confines of the country. This paper describes the trials and same experimental results.
