Research on Electromagnetic Interference Protection of Nuclear Power Unit Equipment Under the Application of New Wireless Technology in Smart Nuclear Power

Intelligence is the trend of industrial development in today's world, which will inevitably affect the nuclear power field, thus promoting nuclear power industry from digital to intelligent forward. 5G and Wi-Fi6, as a new generation of wireless communication technologies, have important advantages in terms of technical performance and security due to the characteristics of dense personnel, wide equipment distribution, complex facility environment, and special materials used in nuclear power scenarios. Considering the high requirement of electromagnetic compatibility (EMC) in nuclear power environment, it is urgent to further study the electromagnetic interference and protection requirements of 5G, Wi-Fi6, and other new technologies on nuclear power unit equipment in nuclear power environment. In this paper, combined with relevant national document standards and industry standards, we will sort out the requirements of immunity about radiofrequency radiation (RFR) for the important equipment in nuclear power plants, and use signal generators to simulate new radio signals such as 5G and Wi-Fi6 to test the immunity of nuclear power instruments and meters. Combining the results of the test, we will study the EMC between new wireless technologies and nuclear power plant equipment from different factors, such as power, bandwidth, modulation, distance, and direction. And then, we will summarize the protection requirements about nuclear power equipment and propose interference protection measures.
