The impression I've gotten is that almost all of the massive bills associated with nuclear power are because of an irrational fear of the radiation. Factoring in all the nuclear disasters and the radiations released from them, nuclear causes something on the order of 10,000 times fewer deaths than coal per megawatt generated.

That's kinda like saying we can release the tiger from the cage because it hasn't killed anyone while it was in the cage.
No? It's like saying that its safe to have more zoos with tigers because tigers pretty much never get out of their cages and get a to kill people unless there is some massive fuckup (i.e. you let soviet engineers supervise your tiger)
>No? It's like saying that its safe to have more zoos with tigers

No, then the original statement would have to have been "we should keep paying big bills so we can have safe nuclear", but it wasn't.

To be more direct, using statistics about incidents to claim something is safe a fallacy. Something extremely dangerous that is kept safe through effort and expense won't appear in the stats until you remove the effort and expense.

After genetically engineering a super tiger and keeping it hungry.
Not quite, because there have been disasters and radiation leaks. And if the number of deaths per megawatt produced is 10,000 times less than coal, despite those radiation leaks, radiation leaks cannot be anywhere as dangerous as commonly perceived.
> nuclear causes something on the order of 10,000 times fewer deaths than coal per megawatt generated.

If we demonstrate scientific honesty and begin to apply the same level of techniques that are used to obtain the result of "10,000 times fewer deaths than coal per megawatt", we can come to the conclusion that even a small accident at a small nuclear power plant can destroy life on planet Earth as a phenomenon.

“Better than coal” is a weak argument. Coal hasn’t been in the “game” for decades. The problem for nuclear isn’t anything irrational - it’s economics and operational and deployment flexibility - newer tech like solar PV, gas turbines, batteries and wind have created a new Pareto frontier for electricity generation and nuclear just isn’t anywhere near this frontier for any objective.

What are talking about?

* China's installed coal-based power generation capacity was 1080 GW in 2021, about half the total installed capacity of power stations in China.*

India is the fifth-largest geological coal reserves globally and as the second-largest consumer, coal continues to be an indispensable energy source, contributing to 55% of the national energy mix. Over the past decade, thermal power, predominantly fueled by coal, has consistently accounted for more than 74% of our total power generation.

The last new coal power plant to come on-line in the US was in 2013 at Sandy Creek - 13 years ago. The last new coal power station built in Australia - Bluewaters Power station was built in 2009 - 17 years ago. In Europe coal's share has dropped from over 40% of generation at its peak in 2007 - about 20 years ago - and has declined to about 9%. Coal's days are over - natural gas is cheaper and more flexible, while solar PV and wind are cheaper.

There is of course a large installed base - a coal plant will last 50 years. The fact that developing countries have large installed coal capacity is neither here nor there.
