Scientists create more efficient nuclear power fuel
United States researchers have re-designed nuclear reactor fuel by changing 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 700C, much lower than 1800C for conventional fuel and further from the 2840C melting point for uranium fuel.
The Massachusetts Institute of Technology researchers believe they can make nuclear power plants 50 per cent more powerful and safer.
