There are about a half dozen nuke plant designed that are state of the art, including thorium plants, that are much safer just based on the design. We've not built a new nuke plant since what, the 70's? The technology is so much better now. One has the uranium as pellets rather than rods so it's easier to seperate so don't have to be cooled off as much in case of a massive system shut down.
You must have not read the articles, I am not suprised. Thorium has a higher yield than Uranium which means it is more efficient. Thorium is easier to cool down, it is all about the science,yo. Here is the thing that bugs most elected officials about Thorium; it is readily avalaible everywhere, which means the oil companies/Uranium companies will never let it happen.
