“In reality, the story of nuclear power development in the US over the last 50 years is beyond pitiful and would not pass muster under any “normal” business plan. How the nuclear industry gets away with it remains baffling.”
“I happen to be one who believes that we will not get very far in working out a peace program, or in lowering the suspicious fingers which are now being pointed toward America by other nations of the world, until we recognize that, after all, the secret of atomic energy does not belong to America, but that, instead, it belongs to all mankind.”
“And Lord, we are especially thankful for nuclear power, the cleanest, safest energy source there is. Except for solar, which is just a pipe dream.”
“Our children will enjoy in their homes electrical energy too cheap to meter.”
“In some sense, nuclear fission is not one of those developments in physics which arose logically and systematically in the course of progress. There was a great deal of accident and surprise in the process.”

A energia nuclear é o uso de reações nucleares para produzir eletricidade. A energia nuclear pode ser obtida a partir de reações de fissão nuclear, decaimento nuclear e fusão nuclear. Atualmente, a grande maioria da eletricidade proveniente da energia nuclear é produzida por fissão nuclear de urânio e plutônio em usinas nucleares. Processos de decaimento nuclear são usados em aplicações de nicho, como geradores termoelétricos de radioisótopos em algumas sondas espaciais, como a Voyager 2. Reatores que produzem energia de fusão controlada têm sido operados desde 1958, mas ainda não geraram energia líquida e não se espera que estejam disponíveis comercialmente no futuro próximo.
