Enhancing Temperature Measurement Accuracy and Reliability in Nuclear Power Plants
Thermocouples are used in nuclear power plants to measure temperature. Thermocouples are located in guide tubes. It is proposed to check the correctness of their installation in the guide tubes from their thermal transient response. The experimental studies show that the transient response of a correctly installed thermocouple is considerably lesser that that in case of improper installation. The time constant of the thermal transient response considerably depends on the thermocouple diameter. So the proposed method can be used to check the correctness of installation of thermocouples in guide tubes of the reactor of nuclear power plants.
