I am in favor of more nuclear power and I know very little about the field, but this argument never resonated with me.
If the Chernobyl series paints a reasonably realistic image of what could have happened had they not contained the melt down, we are talking "better part of a continent being uninhabitable for thousands of years". When that is the potential risk, comparing death counts from non-catastrophic scenarios isn't what we should be looking at.
