Earlier quoted context omitted.
"risk of a wind turbine is, and always was, zero" seems like you need to check on how many people die a year while maintaining wind turbines. Fukushima accident: corruption Chernobyl: incompetence Three mile island accident: that's a bit more nuanced than just human error, but nothing we haven't fixed already SL-1: suicide-murder/human error Those are the serious accidents. As you may see, all are perfectly fixable.…
How is human error fixable?
You mean corruption and incompetence isn't? It's not like someone accidentally pressed wrong button or something. There are clear issues which can be fixed with more regulations when building nuclear plants and who can operate them.
Can't say much for other two, since it's more just human error. One's more of a technical problem that was addressed poorly and other, too unique to happen again. People don't usually murder/suicide in nuclear plants.
