Absolutely not true.
There are no new generation nuclear reactors in US at all. There have been only 65 direct deaths for 30 years from nuclear plants. While hundreds of people a year die in coal mines and now this oil spill, plus indirectly all the lung cancer people get from
pollution. Just look at US energy map and see how it is powered.
New generation nuclear plants, used in France for example, are very efficient and produce less waste than average american family does.
Now there is a joint effort between US DOE and Russian Ministry of Nuclear Energy on a new generation nuclear power plant which has almost 0 waste, becasue most of it just get recycled.
So at the end nuclear is cheap, fast, clean and safe. You can put "...est" and the end of those words and it will be true.
