Intrinsic Junction Thermocouples for Surface Temperature Measurement

Year: 2025

Type: article

Abstract: The material selection, attachment, and calibration of intrinsic junction thermocouples (TC) are discussed. Intrinsic junction thermocouples are utilized for their fast response times in surface measurements during high thermal transients. The as-is measurement and calibrated corrections are presented for both the out-of-pile pulse power system and the critical heat flux experiments in the Idaho National Laboratory Transient Reactor Test facility. The fin effect from temperature measurements on the surface of fuel cladding is corrected using a linear coefficient, m, and temperature corrections are sometimes 100 °C or more—representing 18% of the original temperature measurement.
