I'm kind of surprised there's so many nuclear power companies. I remember Google signed a deal a year or so ago [0] with a different one (Kairos). I wonder why they're not in this deal? Is it all connections and funny money? Or do any of these have real shots at making something useful?
I was thinking how the dotcom bust left a lot of dark fiber infrastructure which helped the internet take off after that. It would be great if the upcoming AI bust (if it happens) leaves a bunch of power generation and new nuclear tech behind.

The dark fiber analogy doesn't quite work though, because unused fiber just sits there harmlessly. Nuclear plants have massive decommissioning costs ($280M-600M+ per plant), ongoing waste storage requirements, and if the companies go bust, taxpayers are likely on the hook. The EU alone is underfunded by €118 billion on decommissioning. Meanwhile batteries and solar keep getting cheaper every year without the “who pays to clean this up in 50 years” problem. Seems like a very roundabout way to hope for public benefit.
with small companies it's like with startups - some might fail so maybe it's better to have more players. I still think this is strange - if they wanted nuclear - could have approached GE for some BWRX of ABWR or W-house & KHNP for some nice AP1000/alike units
Right. Meta wants big enough plants that an AP1000 or two would be the right size. They're known to work. There are four in operation, two in the US, and another dozen or so under construction.
Most of the small nuclear reactor startups hand-wave the failure modes and argue that they don't need the hulking big expensive containment building. NuScale claimed that. They wanted multiple reactors sharing the same cooling pool. If they ever had a leak, the whole set of reactors would be contaminated, even without a meltdown.
If we look at the big reactor accidents so far, there's Chernobyl, with no containment building. There's Fukushima, with too small a containment unable to contain the pressure. And there's Three Mile Island, where a large, strong containment building contained a meltdown. Three Mile Island was an expensive disaster, but not hazardous outside the plant. That's the failure mode you want.
We might be better off at developing better techniques for welding thick sections to make hulking big, strong containment vessels. There's been progress with robotic welding of thick sections.[1]

This is actually American capitalism working at its finest.
Have you seen a video of a slime mold "solving" a maze? It reaches out in every direction with thin tendrils until it makes contact. (Then the game shifts.)
We have a sense, like a slime mold picking up on the "scent" of food, that there is energy. But there are lots of good hypotheses for how we get there. So we try them. Not exhaustively. But multiply. When someone demonstrates they've got it, the game will shift to consolidation and scaling.
