CNNC Puts Its First Independent 1-Million-Kilowatt Nuclear Turbine Control System into Operation

Recently, with the successful one-time start-up and grid connection of Unit 3 at Fuqing Nuclear Power Plant after its 7th refueling and maintenance, the first independent 1-million-kilowatt unit turbine control and protection system of China National Nuclear Corporation (CNNC) was officially put into operation. 

This marks a landmark progress in CNNC’s independent research on core nuclear power control systems.

China Nuclear News reports that the nuclear power turbine is the core power equipment for converting nuclear energy into electrical energy, and the turbine control system, known as the “nerve center” of the turbine, mainly includes core modules such as the turbine regulation system and protection system. 

It is responsible for accurately regulating core parameters such as turbine speed and output power throughout the process, and achieving its localization is a key task for the high-quality development of China’s nuclear power industry. 

As a key part of nuclear power equipment, the independence of the turbine control system is crucial to ensuring the safety and autonomy of nuclear power plants. 

For a long time, the core control systems of China’s large-scale nuclear power units relied heavily on imports, which restricted the independent and controllable development of the nuclear power industry.
