One U.S. Nuclear Reactor Uses as Much Water as All of D.C. - Technology - The Atlantic Wire:
"It takes the same amount of water required by a city of 5 million to fuel a typical U.S. nuclear power plant for one hour: 30 million gallons, Fast Company reports. Charles Fishman, author of the book The Big Thirst, notes that 'the U.S. has 104 nuclear power plants--more than any other country, a quarter of all plants worldwide.' As the world's largest energy consumer, '49% of the water used in the U.S. goes to generate electricity,' Fishman notes. That's 'the single largest use of water' in the country."
This cannot be correct, can it? After the water is used is it radioactive?
