Abstract
The Idaho National Laboratory’s Measurement Science group has advanced the capabilities of the nuclear grade: High-Temperature Irradiation-Resistant thermocouples (HTIR-TC) Ref. [1] to measure real time temperatures of fuels and the general in-core environment. The HTIR-TC is comprised of a mineral insulated, metal sheathed (MIMS) cabling with niobium and molybdenum thermoelement junction and niobium outer sheath. The refractory metals Nb and Mo were utilized for their extreme high melting temperature (2,469°C and 2,623°C, respectively) and relatively low neutron absorption cross section (1.48 barns and 2.48 barns, respectively)—in contrast to the other refractory metals.
