The water, held under high pressure to keep it from boiling, produces steam by transferring heat to a secondary source of water. The steam is used to generate electricity. Cooling water from the river condenses the steam back into water. The river water is either discharged directly back to the river or cooled in the towers and reused in the plant.

Under normal conditions, nuclear power plants receive power from generator. However, during an accident a plant may lose access to this power supply and thus may be required to generate its own power to supply its emergency systems. These electrical systems usually consist of diesel generators and batteries.
The cooling canal system, cooling lake, and the supplementary cooling towers are completely bypassed in this mode of operation. Indirect open-cycle mode : [ f ] Intake from canal leading to the Kankakee River , [ e ] [ g ] discharge to cooling canal leading to Dresden Cooling Lake, [ h ] discharged from lake through return cooling canal that ...

The efficiency of a conventional steam–electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle). The rest of the energy must leave the plant in the form of heat.
