please consider filling in some gaps -- in the United States, for instance, your current map does not show any of the "experimental" reactors, and is even missing some of the Power Utilities reactors I am familiar with. I suspect that the DOE (US) has databases and maps which show most of those.

There are many (not currently shown) in eastern Washington State, and many in Idaho State (US)

I also have a friend who did the geologic surveys for a number of commercial nuclear stations in Africa -- so perhaps those did not end up in the database you used to source your data?
