Development of Ultrasonic Thermometry for Application in LMFBR Safety Research

摘要

Results of three recent tests using ultrasonic thermometry for temperature profiling in nuclear reactor accident studies are discussed. Temperatures to near 3000 exp 0 C have been measured. Multielement sensors of up to 14 measurement zones have been used with less than 15 mm spatial resolution. Ultrasonic thermometry development and sensor fabrication techniques necessary to achieve these results are presented. (ERA citation 10:006876)
