On June 28, 2022, the second phase of the CNNC Sanmen nuclear power project, a major national energy project, was officially started. The second phase of the project will build two million-kilowatt nuclear power units, with an annual power generation capacity of 20 billion kWh after completion.

Sanmen Nuclear Power Plant is located in Sanmen County, Taizhou City, Zhejiang Province. It plans to build six million kilowatt advanced pressurized water reactor nuclear power units, which will be constructed in three phases. The first phase of the project, Units 1 and 2, will be connected to the grid for commercial operation in 2018. The annual power generation capacity is 19.98 billion kWh, and the accumulated safe power generation has exceeded 60 billion kWh.

After the second phase of the project is completed and put into operation, the installed capacity of Sanmen nuclear power plant will reach 5 million kilowatts, and the annual power generation of the four units will reach 40 billion kWh, which is equivalent to reducing carbon dioxide emissions by 30 million tons per year, which will effectively promote the industrial structure and energy structure of Zhejiang Province. Optimization to ensure the security of East China power grid and regional energy supply.Editor/Ma Xue
