Cumulative safe power generation of China's Sanmen Nuclear Power Phase I exceeds 150 billion kWh
According to reports, as of 00:00 on October 5, 2026, the cumulative safe power generation of Units 1 and 2 of China's Sanmen Nuclear Power Phase I exceeded 150 billion kWh. It is reported that Sanmen Nuclear Power Phase I is among the world's first AP1000 third-generation nuclear power units to be completed and put into operation, and Unit 1 officially entered commercial operation in 2018. As one of the world's first AP1000 third-generation nuclear power projects, Sanmen Nuclear Power Phase I has exemplary significance in technical verification and the accumulation of operating experience. The AP1000 adopts a passive safety system and is designed to maintain a safe state for an extended period after an accident without relying on external power sources or manual intervention. In terms of environmental benefits, since being put into operation, Sanmen Nuclear Power Phase I has cumulatively saved more than 42 million tons of standard coal and reduced carbon dioxide emissions by more than 110 million tons. This clean electricity is continuously transmitted to East China and the Yangtze River Delta region, helping to promote the low-carbon transformation of the energy structure while ensuring a stable regional power supply. Compared with thermal power of the same scale, nuclear power does not produce atmospheric pollutants such as sulfur dioxide, nitrogen oxides, and soot, and has a long-term effect on improving regional air quality. According to the planning of the Sanmen Nuclear Power Base, construction of the remaining units will also be advanced. After all units at the base are completed, annual power generation can reach 60 billion kWh, which will further enhance the zero-carbon electricity supply capacity of East China and accumulate experience for the large-scale and standardized construction of China's coastal nuclear power bases.
