Construction begins on the eighth unit of Tianwan: New Nuclear

February 25, 2022

Construction of Unit 8 of the Tianwan nuclear power plant in the Chinese province of Jiangsu officially started on February 25 with the pouring of the first concrete for the reactor’s nuclear island. The unit is one of four VVER-1200 reactors supplied by Russia to China under a 2018 deal.

In June 2018, Russia and China signed four agreements, including for the construction of two VVER-1200 reactors as units 7 and 8 of the Tianwan power plant. In addition, two more VVER-1200 units were to be built at the new Xudabao (also known as Xudapu) site in Huludao, Liaoning Province.

Work on Tianwan 7 and 8 and Xudabao 3 and 4 was launched on May 19 at a ceremony attended by Chinese President Xi Jinping and Russian President Vladimir Putin via video link. The ceremony included the pouring of the first concrete for Tianwan 7.

Russian state nuclear company Rosatom announced today that a ceremony has now taken place at the Tianwan 8 construction site to mark the pouring of the first concrete.

“The documentation prepared by the engineers of the St. Petersburg Design Institute of Atomenergoproekt JSC and handed over to the Chinese customer enabled the concrete pouring procedure to start according to schedule,” AtomStroyExport (ASE) said.

The Tianwan plant is the biggest example of Russian-Chinese economic cooperation, Rosatom said. Tianwan’s first two units are Russian-built VVER-1000 reactors, which have been in commercial operation since 2007. Three years later, Rosatom and China National Nuclear Corporation (CNNC) signed a general contract for the construction of the next stage of the Tianwan project – units 3 and 4, which entered commercial operation in 2018.

In March 2019, a ceremony was held in Beijing to sign a general contract for the construction of Tianwan Units 7 and 8. Within the framework of this project, an intergovernmental agreement and a framework contract were signed for the construction of the VVER-1200 reactors. In accordance with this, Rosatom will design the nuclear island and supply the key equipment, as well as the nuclear fuel for the two units. The units are expected to be commissioned in 2026-2027.

“Cooperation between Russia and China in the construction of nuclear power plants has been going on for more than a decade,” noted Alexei Bannik, vice president of China projects at ASE.

“We know and appreciate each other as effective partners, good friends and assistants in the implementation of the most important strategic projects. Now we are working on the implementation of new contracts – four of the most powerful units of the generation 3+ VVER-1200 are expected to be connected to the Chinese power system in the coming years, the design and delivery of the equipment is already actively and uninterrupted, and we have the most important construction works ahead of us.
