Liquid lead-bismuth eutectic (LBE) was used as coolant and spallation target in Accelerator Driven Sub-critical System(ADS). However, structural material corrosion caused by LBE is a serious problem which can lead to a system failure. Through controlling concentration of dissolved oxygen in LBE, the oxide scales can form on the surface of the material and protect the material from corrosion. At present, there are mainly two methods of oxygen control, which are gas phase oxygen control and solid phase control. Both of them have considerable disadvantages when applying to large scale nuclear systems. In this paper, the researcher fabricates an electrochemical oxygen pumping (EOP) which has been widely used in industry production in order to achieve highly accurate control of the dissolved oxygen concentration in LBE systems. In this paper, a set of electrochemical oxygen pumping is designed.
