Ultrasonic Doppler velocimetry (UDV) with a titanium-tipped transducer has been successfully demonstrated for measuring a velocity profile of molten lead-lithium eutectic alloy (PbLi) with a concentration of oxygen and moisture lower than 1 ppm. In contrast, it is found that UDV does not work for PbLi flows in a more oxygen-rich environment. This paper presents UDV measurements of PbLi flows at different levels of ambient oxygen concentration, and then discusses the measurement deterioration, based on a thermodynamic consideration of oxides formation in molten PbLi. In summary, it can be concluded that in an oxygen-rich environment, titanium oxidation occurs and consequently deteriorates the acoustic coupling between the transducer tip and the molten PbLi.
