Tianwan NPP. At Tianwan NPP Unit 7, which is being built in China with the participation of Rosatom, the beams of the polar crane were put in place allowing the installation of the polar crane, which has a lifting capacity of 360 tons. Until the completion of the construction, the polar crane will carry out lifting and transport operations for the installation of large-sized equipment in the pressurized zone of the reactor building (reactor vessel, steam generators, pressure compensator),  transport and technological operations during NPP operation. The Tianwan NPP is the largest project of economic cooperation between Russia and China. Currently, two power units  are being built under the Russian VVER-1200 project. The four units of the Russian VVER-1000 project built earlier are successfully operating.
