Not quite a two-seater hybrid electric, but ORNL's new nuclear fuel promises to boost efficiency by as much as 900%.

U.S. Nuclear reactors are not known for their fuel efficiency. At a mere three to four percent burn-up, much of the uranium fuel is wasted and current reactors produce large amounts of unsightly nuclear waste. Advanced gas reactors may offer a better choice for the aging U.S. nuclear power posse.

Working together with the Idaho National Laboratory (INL) and the Babcock & Wilcox Company, Oak Ridge National Laboratory (ORNL), with funding from the Department of Energy's Office of Nuclear Science, has produced a new fuel for the high temperatures of advanced gas reactors. In tests conducted at the Advanced Test Reactor at INL, the fuel reached a nine percent burn-up, a near three-fold efficiency gain from traditional water-cooled nuclear plant fuel and halfway to the targeted 16 to 18 percent.

The fuel, produced in the ORNL Materials Science and Technology Division, is made up of thousands of tiny carbon and silicon carbide coated spheres of uranium, which are compressed into fuel sticks and loaded into a graphite form.

With growing concerns about nuclear reactor waste products, skeptical outlooks for the future of nuclear power and foreign companies selling mini-plants to U.S. customers, a new, more efficient fuel made in America is a ray of hope for U.S. nuclear power advocates. Though it will possibly never be without its own pollution problems, further refinement and research into fission reactors may yield a very efficient and comparatively clean energy generation model.

The only thing bad about that plant is that its decommissioned.

So instead of the one in several thousand, or tens of thousand, chance of the nuclear plant blowing up, you'd rather have a coal plant spewing black smoke.

You base nuclear safety off the few incidents of disaster from poorly funded plants. And even if it was 100% guaranteed that a nuclear plant would never have problems, they'd still have speakers outside to warn of a problem. It's called "just in case".

Not to mention the radioisotopes a coal plant churns out on a daily basis is astounding.
