Abstract: With the continuous development of electronic technology, smart nuclear power has become one of the trends in the future development of nuclear power. One of the foundations of smart nuclear power implementation is the implementation of wireless network coverage in nuclear power plants to meet the operational maintenance digitalization, mobility and full process tracking control. The paper first introduces the basic network setup and plant layout requirements of Fuqing nuclear power, and then analyzes several wireless communication technology characteristics, and finally analyzes the application of WIFI wireless technology in Fuqing nuclear power production plant. The analysis results show that the real-time WIFI network is deployed in the non-critical areas of Fuqing nuclear power, and the wireless network used during the overhaul of the unit is deployed in key sensitive areas.
