Abstract
Fundamental research to understand changes in piezoelectric properties under irradiation are required if ultrasonic sensors are to be designed and deployed for nuclear reactor in-core measurements. Previous research has examined the survivability of bismuth titanate (BiT)-based ultrasonic sensors to a total dose of up to ~1021 neutrons/cm2. This paper describes efforts to quantify the changes in piezoelectric properties in these materials using piezoresponse force microscopy (PFM). PFM measurements from non-irradiated and irradiated specimens indicated a decrease in d33 from irradiation, consistent with the observed decrease in the response of a BiT transducer over the course of the irradiation test.
