Abstract: For nuclear reactors measurements, the monitoring and control of temperature is pertinent to the safe operation of the reactor. The desirable requirement for the temperature sensor is safety class 1E, quality assurance QA1, radiation resistance, Anti-seismic and requirement of LOCA (lost of coolant accident). Since the sensors are installed in the core, it should meet the requirement of high accuracy, long life, irradiation resistance, anti-seismic and the LOCA experiment. In this paper the research and development progress of this temperature sensor are introduced from the view of component, structure and the qualification experiments. This paper also summarizes qualification experiment items and the performance of the thermocouple sensor produced after the tests by chongqing material research institute. The achievement provides an important reference for the independent research of this kind of products in china.
