How many nuclear power plant reactors are there in the United States?

A few people visiting the nuclear power plant and seismic hazard page have noted that their only appears to be around 63 nuclear power plants on the map, yet, they say, there should be 104. At first I thought they were confused because many of the nuclear power plant facilities have more than one reactor. Some have as many as 3. So, I checked with the NRC and found 2 different lists that had 64 plants and 103 reactors, but the lists were not identical. A few plants appearing on one list, did not appear on the other. So, to get at the bottom of this and find the most current list of operating nuclear power plants in the U.S. I am going to compare the two NRC lists with those from Nukeworker.org, IEA and the World Nuclear Association and come up with THE list.

Note that if you look at the current spreadsheet or shapefile that you may download from this page, you will find several other types of nuclear related facilities besides Nuclear Power Plants. In the future, I'd like to also list and document all the non-energy related reactors that are in operation at national laboratories, universities, hospitals, research firms and elsewhere. Beyond that it is also important to document decommissioned nuclear power plants and other places that nuclear waste is currently stored.
