Rosatom has started building the eighth unit of the Tianwan nuclear project, located in the Jiangsu province of China. As part of an agreement signed in June 2018, four VVER-1200 reactors will be supplied by Russia to China, including two for the Tianwan project (units 7 and 8) and two for the Xubadao project in Liaoning (northern China). Tianwan 7 and 8 are expected to be commissioned in 2026-2027.
The Tianwan nuclear power plant is operated by the Jiangsu Nuclear Power Corporation, a joint venture between CNNC (50%), China Power Investment Corporation (30%) and Jiangsu Guoxin Group (20%). The power plant already includes a first phase of two 990 MW (1,060 MW gross) units, which were commissioned in 2007. Tianwan-3 (1,060 MW net, 1,126 MW gross) entered commercial operation in February 2018 and Tianwan-4 (990 MW net, 1,060 MW gross) in December 2018. Two additional 1,000 MW (1,080 MW gross) ACPR1000 reactors, Tianwan-5 and 6, were commissioned in September 2020 and June 2021. Tianwan-7 entered construction in May 2021. With all eight reactors in operation, Tianwan would become the largest nuclear power plant in the world, with a total capacity of 8.1 GW.
