Embedded Cladding Surface Thermocouples on Zircaloy-Sheathed Heater Rods.

摘要

Titanium-sheathed Type K thermocouples embedded in the cladding wall of zircaloy-sheathed heater rods are described. These thermocouples constitute part of a program intended to characterize the uncertainty of measurements made by surface-mounted cladding thermocouples on nuclear fuel rods. Fabrication and installation detail,and laboratory testing of sample thermocouple installations are included. (ERA citation 02:059180)
