Which has never happened

which, as we all know, implies that it will never happen ...

actually, after reading through your whole comment, it has a few issues:

Unjustified fears of it blowing up and destroying the world are ridiculous and overblown, especially given modern advances in reactor design and safety.

Yes, you're right, nuclear power plants are safe as long as nobody in engineering royally fucks up. But, as we all know, engineers never fuck up and forget an important detail ... (/s)

But this is generally just a problem with all our infrastructure in the developed world in general… we don’t renew or upgrade it… we just keep patching it and then we wonder why everything is so shitty and inefficient… because we refuse to actually upgrade things in a real way

This sounds like a popular thing to me ... people think that replacing old things will make them better / more efficient. When that is simply not true. Banks, for example, still use programming language from the 1960s. Why? because actually it turns out that that stuff just works. Meanwhile newer languages each introduce their own new kind of problem. The same phenomenon happens in many cases. I was told that airplanes do the same, using flight control software from 20th century ... for the same reasons. "newer" does not imply better.
