Here's a great read about nuclear power:

This was the most interesting part:

France, which generates nearly 80 percent of its electricity by nuclear power, seems to think so. So do Belgium (56 percent), Sweden (47 percent) and more than a dozen other countries that generate at least one-fourth of their electricity by nuclear power. And who is the world’s single largest producer of nuclear energy?

Improbably enough, that would be . . . the United States. Even though the development of new nuclear plants stalled by the early 1980s, the country’s 104 reactors today produce nearly 20 percent of the electricity the nation consumes. This share has actually grown over the years along with our consumption, since nuclear technology has become more efficient. While the fixed costs of a new nuclear plant are higher than those of a coal or natural-gas plant, the energy is cheaper to create: Exelon, the largest nuclear company in the United States, claims to produce electricity at 1.3 cents per kilowatt-hour, compared with 2.2 cents for coal.
The article has a good look at coal vs nuclear power.
