Coal on the other hand is relatively cheap, the technology is fairly simple, running them is fairly cheap, there’s no waste to get rid of etc

You know, the actual dangerous part of those nuclear accidents everyone is always thinking about.

If a nuclear plant leaked even a fraction of that amount of radiation it would be shut down immediately. But all of that gets to be ignored, because it’s not a nuclear power plant.
