Ion thermometers in reactor technology
The width of the temperature discontinuity and the thermometric stability of the sensors are constant up to very high flux values. The immediate influence of irradiation is reduced to a decrease in the hysteresis of the conduction curve at the phase transition. When the readings of the ion thermometers are compared with the reading of Chromel-Alumel thermocouples, it is observed that the temperature difference amounts to approximately 7/degree/C in the case of thermocouples placed at the sensor socket; the temperature difference decreases to 2/degree/C in the case of the thermocouple junction situated between the electrodes. The good results obtained in the testing of the ion thermometers in nuclear reactors lead to the conclusion that these temperature sensors are promising for checking thermocouples in the core of nuclear power stations.
