Abstract: The 1E platinum resistance thermometer is used to monitor the water temperature of the main pump in nuclear power plant, participate in the pump shutdown instruction and trigger the reactor shutdown. It plays a vital role in the safe operation of nuclear power plants and is the key instrument control equipment for the safe operation of nuclear power plants. The safety level of the temperature sensor is 1E and the quality assurance level is QA1. The temperature sensor needs to meet the requirements of high precision, long life, radiation resistance and earthquake resistance, and has high technical requirements. The paper introduces the development progress of 1E platinum resistance thermometers from the aspects of technical requirements, development emphasis and quality appraisal, which provides important reference for the independent development of platinum resistance thermometers in China.
Key words: the 1E platinum resistance temperature sensor; pressurized water nuclear reactor; pualification
