Construction sites. Rosatom’s mechanical engineering subsidiaries have shipped equipment for two Russian-designed nuclear power plants being built in China. A set of four primary coolant pump casings will be delivered to Xudabao Unit 4, and four pump units to Tianwan Unit 7. The equipment is intended to ensure coolant circulation in the primary circuit and will be installed at the nuclear islands of the power stations. The Tianwan NPP is the largest Russia-China economic cooperation project, with two Russian-designed power units with VVER-1200 reactors currently under construction. Another four earlier built power units with Russian VVER-1000 reactors have long been in operation, supplying millions of kilowatts of electricity to the country’s power grid. The Xudabao NPP is a relatively new project of Russia-China cooperation in the field of nuclear energy. It was 2019 when the parties signed a general construction contract and a nuclear fuel supply contract for Xudabao Units 3 and 4 with VVER-1200 reactors.
