A simple idea

Scientists create more efficient nuclear power fuel. 01/10/2006. ABC News Online

From the story above:

The scientists changed the shape of the fuel from solid cylinders to hollow tubes, adding surface area that allowed water to flow inside and outside the pellets, increasing heat transfer.

They claim new fuel design is also much safer because it reaches an operating temperature of about 700 degrees Celsius, much lower than 1,800 degrees for conventional fuel and further from the 2,840 degrees melting point for uranium fuel.

Dr Hejzlar, a principle research scientist in MIT's Department of Nuclear Science and Engineering, said it could take up to 10 years to commercialise the new fuel concept.

Seems odd that such a simple idea had not been thought of before.
