SUMMARY
Wireless technology possesses distinct technical and economic advantages in the design, construction, and operations management of nuclear power plants. To improve the level of autonomy of nuclear power plants, we discuss the research on the international system of developing wireless technology applications for use in nuclear power plants. Further studies have enabled the extensive use of wireless technology in China’s nuclear power industry. The application of the proposed wireless sensor technology in nuclear power plants is based on reliability, environmental adaptability, electromagnetic compatibility, scalability, and maintainability requirements. Accordingly, the application will be a gradual process but wireless sensor technology needs to evolve continuously to meet these requirements. This study is designed to implement a thermal instrumentation calibration device using a Windows CE embedded operating system as the core of the test procedures in accordance with the relevant requirements. We also maximize the considerable reliability of an embedded operating system in the traditional areas of metering industry. Results show that in using wireless technology in nuclear power plant, the general thermal instrumentation calibration application of an intelligent device system is low, data accuracy is high, and the process is stable.
