This specification establishes dimensional and material requirements for compacted, mineral-insulated, metal-sheathed (MIMS), high temperature irradiation resistant thermocouples (HTIR-TC) with one HTIR-TC thermoelement pair. These types of thermocouples are suitable for high neutron fluence, up to 1022 n/cm2, and a high temperature, up to 2912 ? [1600 ?].
Irradiation-resistant; Thermocouple; High-Temperature; Nuclear; Transmutation
The standard defines the build and calibration of a high-temperature, irradiation-resistant thermocouple (HTIR-TC) for use in nuclear environments up to 1600?. The standard will guide purchasers and providers with repeatable steps to produce consistent HTIR-TCs.
The title and scope are in draft form and are under development within this ASTM Committee.
