Abstract

Although liquid lead-bismuth eutectic (LBE) is a good candidate for the coolant in the subcritical transmutation blanket, it is also known to be very corrosive to stainless steel, the material of the carrying tubes and the containers. Such a corrosion problem can be prevented by producing and maintaining a protective oxide layer on the exposed surface of stainless steel. Proper formation of the oxide layer critically depends on the accurate measurement and control of the oxygen concentration (tens of ppb levels) in the liquid LBE. An Oxygen Sensor Calibration/Measurement Apparatus is designed and built to deliberately calibrate the Yttria Stabilized Zirconia (YSZ) oxygen sensor. A detailed description of this system with main components and their functions is presented. Some calibration results have been done and is presented and analyzed here. Analysis on the characteristics of this YSZ sensor and the effectiveness of the calibration apparatus are also discussed.
