Abstract

Several options have been identified that could further enhance the reliability and extend the applicability of recently-developed Idaho National Laboratory (INL) High Temperature Irradiation Resistant Thermocouples (HTIR-TCs) for in-pile testing, allowing their use in higher temperature applications (up to at least 1800 °C). The INL and the University of Idaho (UI) are investigating these options with the ultimate objective of providing recommendations for alternate thermocouple designs that are optimized for various applications. This paper reports the status of 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 preliminary insights gained by comparing the performance of thermocouples fabricated with various heat treatments and alternate geometries.
