There's also the huge difference between solid fuel rods used in uranium-fueled nuclear reactors and the liquid fuel used in molten salt thorium reactors. Solid fuel rods break down beyond use after less than one percent of the fissile material has been consumed, at which point the entire reactor must be shut down and the fuel rods replaced. With molten salt reactors, the fuel is constantly being replenished and the waste removed during operation, allowing a much larger portion of the fissile material (up to 99%) to be consumed before being treated as waste. http://en.wikipedia.org/wiki/Liquid_fluoride_thorium_reactor#Economy_and_efficiency http://en.wikipedia.org/wiki/Liquid_fluoride_thorium_reactor...
