This is also a largely solved problem in the form of self contained plants

Basically, the idea is that you remove the human factor where possible (and modern robotics/drone technology can handle where humans ARE needed... to a degree) and build it with the focus on protecting that valuable waste from bad folk.

There are definitely some concerns still, but this combined with much safer reactor technology gets rid of a lot of the concerns.

One of the big problems is that even a lot of existing tech is still very old because people are terrified of nuclear energy and don't want to build new stuff. Which leads to making do with old stuff and finding ways to retrofit. Which is basically NASA's problem just with fear instead of apathy leading to crap budgets.
