What they are talking about is what is used to condense the steam exiting the main turbine which is the thing that spins the generator. DC uses seawater to run through the condenser and then back out to the sea, warming the water about 20 degrees if I remember correctly. This is why you see most nuclear plants along the coast or lining the Great Lakes.

The only other methods I am aware of are the giant cooling towers people associate with nuclear plants or ponds (more like canals which snake back and forth, see Turkey Point in Florida) which allow the water to cool before reuse.
