N2 - Electrochemical oxygen pumping method was applied in order to control the dissolved oxygen concentration in liquid lead–bismuth eutectic (LBE). The oxygen pump was fabricated using yttria partially stabilized zirconia (YPSZ) as a solid electrolyte and LSM (strontium-doped lanthanum manganite)–GDC (gadolinium-doped ceria) composite as a cathode. An oxygen control system, comprising of the oxygen pump, an oxygen sensor and a DC current source as well as a proportional-integral-derivative (PID) controller for the current control, was applied to regulate the dissolved oxygen concentration in liquid LBE. Highly accurate control of the oxygen concentration was achieved by this system. In addition, the feasibility of using the pumping system for measuring corrosion kinetics of structural steels in liquid LBE was demonstrated
