Because nuclear is effectively done for. The dream was "power too cheap to meter". Didn't come true back then, and it turns out after you account for safety systems like a containment building and backup cooling, it's far more expensive than alternatives. To make things worse, making nuclear remotely profitable relies on running it as close to 24/7 as possible. Given that renewables exist and produce cheaper power, nuclear only gets to offer anything when renewables aren't working, which makes it even more expensive. Economically, it's extremely risky. Why risk billions on a plant that might profit 20 years down the line, when you could build solar or wind faster, and profit faster? Politically, it's not great because construction times are very long, so any politician that starts building them probably won't be there to see the benefit, and may have their work stopped by a successor. Practically, we can't build it fast enough. It's a big, complex, specialized tasks that few people do because there's not much market.
