Tianwan Nuclear Power Plant

Tianwan Nuclear Power Plant is the world's largest nuclear power base in terms of total installed capacity, both in operation and under construction. It is also a landmark project in China-Russia nuclear energy cooperation.

The Tianwan Nuclear Power Plant, located in Lianyungang City, Jiangsu Province, is the world's largest nuclear power base in terms of total installed capacity, both in operation and under construction. It is also a landmark project in China-Russia nuclear energy cooperation. The plant is planned to include eight million-kilowatt-class pressurized water reactor units, with Units 1-6 already in commercial operation, while Units 7 and 8 are under construction and expected to be commissioned in 2026 and 2027, respectively. Once fully completed, the total installed capacity of the Tianwan Nuclear Power Plant will exceed 9 million kilowatts, generating up to 70 billion kilowatt-hours of electricity annually, providing stable and clean energy for the East China region.
Beyond electricity generation, the Tianwan Nuclear Power Plant has pioneered a new model of comprehensive nuclear energy utilization. In 2024, China’s first industrial nuclear steam supply project, "Heqi No.1", was completed and put into operation at Tianwan. This project delivers 4.8 million tons of industrial steam annually to the Lianyungang petrochemical industrial base through a 23.36-kilometer pipeline, replacing traditional coal consumption and reducing carbon emissions by over 700,000 tons per year. It provides a green and low-carbon energy solution for the petrochemical industry.
Additionally, the Tianwan Nuclear Power Plant plays a crucial role in ensuring regional energy security. Its electricity is transmitted to the Yangtze River Delta region through eight 500-kilovolt transmission lines, providing strong support for regional economic development. The plant places great emphasis on operational safety, employing technologies such as smart inspection stations, drones, and AI-based "Eagle Eye" monitoring systems to enable 24/7 surveillance of transmission lines, ensuring power transmission stability and security.
The construction and operation of the Tianwan Nuclear Power Plant have not only driven advancements in China's nuclear energy technology but also set an example for global nuclear energy utilization. Looking ahead, the plant will continue to explore green energy projects such as nuclear hydrogen production and tidal photovoltaic power, contributing to China’s "dual carbon" goals of carbon peaking and carbon neutrality.
