The USA uses the most nuclear energy. There is the highest number of Nuclear Power Plants in the world. The reason is simple: USA needs energy and the easiest way to get it is building nuclear power plants.
USA and Canada
The USA
nuclear power plant are found in plain areas around the world like in the USA creating nuclear energy
In nuclear power plants, producing electricity
Nuclear energy/electricity varies, but in 2007, USA generated an average of 12.4 billion kilowatt-hours per-nuclear plant.
France produces about 80% of its electricity by nuclear plants, but this is an exception in Europe, most countries with nuclear plants have about 20%, as in the USA. Not sure about Japan, but nuclear appeals there I think because they have little fossil fuels in the country. See www.world-nuclear.org for a more detailed survey.
look at website www.nrc.gov. This has maps and descriptions of all 104 operating reactors in the US
The honest answer is the USA has been producing a great deal of nuclear waste and ignoring the problem of what to do with it. President Obama wants more nuclear power plants, but, has not said what to do with nuclear waste. A lot of waste is stored in nuclear power plants, but, they are getting filled up fast, and that is not really a good idea. The possibility of an accident or theft is very real.
I don't believe that Iran should have nuclear power because they threaten to bomb the USA if they do get nuclear power.

Maybe Chernobyl, but only for a short time. Ever heard of SL1? Both are sad events. There are some very large coal powered plants in the USA and the rival the nuclear plants.
