The first of two steam generators has been hoisted into place at Unit 4 of the Haiyang nuclear power station in Shandong province, northeastern China, paving the way for the connection of the primary circuit of the nuclear island and the capping of the reactor building.
In a pressurised water reactor (PWR) system, the steam generators transfer heat produced by the nuclear reaction to turn demineralised water into steam which is used to power the turbines.
