All of that costs money, and sooner or later some MBA / politician is going to ask why we’re spending so much on something which hasn’t come anywhere near a major event – surely we’d be just as safe spending 10% less and using the money for something else like rewarding shareholders? Setting up governance structures which can resist that kind of pressure for millennia isn’t something we have much experience with.

Micro molten salt reactors make a lot of sense if looked at rationally. Can burn what we currently call "waste" too.

When talking on this kind of scale about a system level failures, the social issues are going to dominate unless it’s something like a fire-and-forget space probe. If you want to see nuclear succeed, the first thing I’d be thinking about is how to ensure that someone doesn’t cut safety to boost their profit margin, accounting for possible future regulatory capture and austerity budgets. Since nuclear is never even going to be within one order of magnitude as distributed as wind/solar, I’d especially think about what would prevent some unscrupulous CEO from pocketing the difference comfortable in the knowledge that their family doesn’t live anywhere nearby.

Nuclear seems more dangerous for the same reason planes seem more dangerous than cars—when something goes wrong, it's a big news event.

Also, the video indirectly suggests that we can replace flood protection with nuclear energy. :-/ Dams are built mainly to protect population from floods, so they SAVE millions of lives every year, while also generating electrical energy, which is used to upkeep dams.

Banqiao incident is pictured like Chornobyl`, but, in reality, a bunch of people lives was SAVED by lower dam. The flood broke 62 dams. Just imagine what may happen when 10 nuclear reactors and/or nuclear waste sites will be flooded instead.

I'd be careful to draw conclusion from such an outlier.

The hysteria of your statement doesn’t appear to be substantiated by a dispassionate look at the facts.

And it's sometimes forgotten that 10s of thousands of people had to leave their homes.

Though some googling reveals that the main contaminant is Cesium-137, which has a 30 year half life. That will fade into background radiation long before that, even ignoring cleanup operations.

They've already reopened parts of the closed area.

188,000 people were evacuated in California following some unexpected rainy weather.
