A resistance temperature detector for reactors

IN A HEAT POWER PLANT, temperature is a major parameter. The accuracy with which it can be measured determines whether the plant can work efficiently, close to the upper boundaries of mechanical strength and close to critical pressures, or whether performance must be sacrificed by leaving wide safety margins. For this reason, and also because of its large power output and lack of cold junction compensation problems, a resistance thermometer is preferable for use in nuclear reactor applications, such as in atomic-powered submarines.
