First, each steam generator was lifted to a height of 19.5m in the fuel building and then introduced horizontally into the reactor building which was followed by the generator being tilted upright and lowered into its final position.

These strategic components, which were manufactured at Areva’s Chalon St-Marcel plant, will transfer heat from the reactor coolant to the water in the secondary system through 6000 U tubes.

The water is converted into steam, which drives a turbine connected to an alternator that in turn generates electricity.

The company said that installation of the reactor coolant system will be completed in spring of this year when the reactor coolant pumps are installed and connected.
