I'm not saying anyone is. I'm saying that nuclear power plants are expensive and people are stupid. Corners are cut and mistakes are made to protect their investment and bottom dollar. I've seen reports of concrete cracking on the outdated nuclear plants (operating past life expectancy) in the US and they're basically ignoring it because they're not critical components, but by the time something happens to a critical component it's a little too late. This is all to protect investment and you end up looking the other way until you can't anymore.
That's a great way to literally do nothing ever. You could make the same claim about coal mines, about hydro dams, about skyscrapers, about bridges, about aircraft, about self-driving cars. Life is risky. We design mitigations and hold ourselves to them. That's why we're alive right now.
