The second of three steam generators at China's forthcoming Tianwan 6 nuclear power unit has been installed, completing a 12-day process that involved bringing the component through a hatch and rotating to a vertical position.

The achievement on 8 April was announced today by China Nuclear Industry 23rd Construction Company.

Units 5 and 6 at Tianwan are domestic design ACPR1000 pressurised water reactors that will produce 1080 MWe when commissioned.

The first four units at the site are Gidropress VVER units supplied by Russia, as will be the seventh and eighth, for which a general contract was signed last month. When they are all in operation Tianwan would become the largest nuclear power plant in the world with eight units and a total generating capacity of about 8100 MWe.
