No. As of 2012, there are no nuclear power plants located in the state of Montana.
Japan has nuclear power plants but no nuclear weapons
No, there are no nuclear power plants in Hawaii. The state relies primarily on imported oil for its energy needs, along with renewable sources such as solar and wind power.
Yes, North Carolina has nuclear power plants. There are currently three operating nuclear power plants in the state: Brunswick Nuclear Generating Station, Harris Nuclear Plant, and Shearon Harris Nuclear Power Plant.
Illinois has several nuclear power plants (see link below) with a total generating capacity of 11,263 MWe. I don't have details of other types of power plants in the state.
There is only one nuclear power plant in Vermont, which is the Vermont Yankee plant in Vernon. Vernon is in the southeast corner of the state.
Tennessee
In the US there are many states that have no nuclear plants, Colorado, Nevada, New Mexico, Utah, and so on. (I am talking about nuclear power plants, not research facilities). See the NRC website www.nrc.gov for maps and details.
Yes. Currently, there are five nuclear power plants operating commercially in Pennsylvania to produce electricity. The use of power in a state is not restricted to power from generating plants within that state, so there is probably power from nuclear plants outside Pennsylvania being used there, and there is probably electricity generated in Pennsylvania that is used outside that state. But certainly, most of the electricity generated by the plants in Pennsylvania is used there.
Kansas and Nebraska both have nuclear plants, also Arizona and Texas.
Illinois has the highest number of power plants, 11. See link below.
There are no nuclear power plants in West Virginia. The state relies mainly on coal, natural gas, and renewable energy sources for its electricity generation.
