An often-overlooked consequence of power generation is "thermal pollution" from excess heat deposited in the envi- ronment. the heating can be considerable. here are some typical numbers: a nuclear power plant generates 1.0 gw of electric power with an operating efficiency of 35%. the reactor has a single-pass cooling system; water from a nearby river is brought in, warmed, and returned to the river. when operating at full power, the plant takes in 90 m3 of water second, comparable to the flow of a small river. if the river water comes in at 10°c, at what temperature does it emerge?
