Coal has already killed far more beings than the highly rare nuclear power station disaster. If you care about wellbeing and human lives, swapping nuclear for coal is downright stupid.
Germany swapped nuclear (and coal) for renewables. While I wholeheartedly agree that it would have been better to extend nuclear in favor of decommissioning coal earlier, that‘ll still not make your argument valid.
Radioactive contamination of soil has very long tail, so we should wait until radioactivity will be lower than background level to count total number of victims. I.e. 1 victim per year x 100 years = 100 victims, while 1 victim per year x 1000 years = 1000 victims, order of magnitude more victims.
