Not sure the stigma will ever go away as long as we are using Uranium as the basis. If we could ever get Thorium based reactors to work and economical I think the public perception would sway considerably when weapon grade material is no longer a possibly byproduct and the worst case scenario drops from a quarantine zone several square miles to power plant just going into lockdown for a few weeks would be a huge step towards public acceptance.

This is unfortunately something that a layperson who's unfamiliar with the tech will always have a hard time understanding. I don't think any reactor built in the US for power generation could ever be used to make weapons grade plutonium. From what I've read we only build light water reactors here, which aren't good for such things. But how many regular folks take the time to learn about all the different types of reactors and how they work and what they're good for? I only did it because the history of nuclear tech intrigues me.

and the worst case scenario drops from a quarantine zone several square miles to power plant just going into lockdown for a few weeks

Similar to above. These new reactors coming online are Gen III reactors, and have passive cooling features, so Fukushima-like events shouldn't be able to happen anymore. But again, few people I think take the time to learn about this stuff at all.

It doesn't help either that regulatory capture has caused old Gen II designs without the passive cooling backups continue to get their licenses extended. Accidents will continue to be bad until we retire the ancient reactors, and start replacing the with new ones that have the benefit of half a century of operational experience and manufacturing advancements to inform their designs to be safer.
