The M.I.T. report predicts that even if the world's fleet of more than 400 nuclear power plants grew to be 4,000 such plants that then operated for a century, the cost of the electricity from those facilities would rise by a mere 1 percent as a result of the increased demand for uranium.

sWow, if hundreds of thousands of tons of uranium are being released by coal power plants it would appear they are more dangerous than nuclear power plants.

LEU fuel is more compact than natural uranium fuel and would thus take up less space in the core.

One attractive feature of fast reactors is that they can produce more fuel than they consume, avoiding the issue of the limited supplies of the uranium used in conventional nuclear reactors.

Like older models, they will use uranium fission to heat water and drive a turbine, but these reactors will be smaller, simpler to build, and each will add more than 1100 megawatts of capacity to the region's power grid when they come online in 2016 or 2017 — without emitting carbon dioxide.
