Options Extending the Applicability of High-Temperature Irradiation-Resistant Thermocouples
Several options have been identified that could further enhance the reliability and extend the applicability of High Temperature Irradiation Resistant ThermoCouples (HTIR-TCs) developed by the Idaho National Laboratory (INL) for in-pile testing, allowing their use in temperature applications as high as 1800 °C. The INL and the University of Idaho (UI) investigated these options with the ultimate objective of providing recommendations for alternate thermocouple designs that are optimized for various applications. This paper reports results from INL/UI investigations. Results are reported from tests completed to evaluate the ductility, resolution, transient response, and stability of thermocouples made from specially formulated alloys of molybdenum and niobium. In addition, this paper reports insights gained by comparing the performance of thermocouples fabricated with various heat treatments and alternate geometries.
