The development of sensors for measurement of temperatures to 2760 deg C in the center of UO/sub 2/-fueled, boiling fuel rods for BORAX-V is discussed. Samples of tantalumsheathed thermocouples with BeO and MgO insulation were tested to failure. Tungsten vs tungsten-26% rhenium was utilized as the thermocouple pair. The first group of thermocouples tested failed at 1650 deg C. Evaluation of 8 other thermocouples showed that the maximum temperature that they can measure accurately is approximately 22OO deg C. The limiting factor is the temperature at which a reaction between BeO and Ta begins. (M.C.G.)
