This article presents an instability model for the high-temperature irradiation-resistant thermocouple (HTIR-TC). Here term defines superposition of both drift and inhomogeneity TC thermoelements occurring simultaneously. The HTIR-TC is advanced (TC) that uses refractory metals niobium molybdenum as sensing generating electromotive force (EMF) in a field neutrons at temperatures upward 1,600°C....
