The energy released in the reactor core is transferred to the primary coolant. Further, the coolant enters the heat exchanger (steam generator), where it heats the water of the second circuit to a boil. The resulting steam enters the turbines that rotate the electric generators. At the outlet of the turbines, the steam enters the condenser, where it is cooled by a large amount of water coming from the reservoir.
