According to the world health organization, the number of premature deaths caused by coal and Particulate Matter is on the order of literally millions per year.

This means that if we switch to nuclear and this caused us to have a chernobyl scale disaster every single year, that it would still be massively safer than coal.
And even if we use your ridiculous example of a nuke going off in a city every year, guess what, that's still safer than coal. (This is, of course, not how nuclear works)
So yes. Give me the bomb going off in a city every single single year. It would still kill less people than coal, according to the World Health Organization.
Yes, really. This is not an exaggeration.
A few extra nuclear bombs going off per year in cities would soon change the desire for this I suspect.
