Nuclear power is unpopular because of media messaging. Coal releases more radiation into the environment on average, even accounting for Chernobyl and Fukushima.
Also because of the naturalism fallacy, and because of word association between “nuclear power” and “nuclear weapons”, and because of the zero-risk bias (most people have a preference for reducing a small risk to zero over a greater reduction in a larger risk).
