from the Economist
There is an awesome amount of energy tied up in an atom of uranium. Because of that, projections of the price of nuclear power tend to focus on the cost of building the plant rather than that of fuelling it. But proponents of nuclear energy--who argue, correctly, that such plants emit little carbon dioxide--would do well to remember that, like coal and oil, uranium is a finite resource.
