At this point, you can be economically anti-nuclear. The plants take decades to build with a power cost well above wind/solar. You can build solar/wind in high availability areas and connect them to the grid across the states with high power transmission lines, leading to less time that renewables aren't providing a base line load. One such line is going in right now from the high winds great plains to Illinois, which will connect it to the eastern coastal grid illinois is part of.
We also have a hilarious amountof tech coming online for power storage, from the expected lithium to nasa inspire gas battery designs, to stranger tech like making and reducing rust on iron.
There is also innovation in "geothermal anywhere" technology that uses oil and gas precision drilling to dig deep into the earth anywhere to tap geothermal as a base load. Roof wind for industrial parks is also gaining steam, as new designs using the wind funneling current shape of the buildings are being piloted, rivaling local solar with a simplier implementation.
While speculative, many of these techs are online and working at a small scale. At least some of them will pay off much faster, much cheaper and much more consistently before any new nuclear plants can be opened.
Nuclear's time was 50 years ago. Now? It's a waste to do without a viable small scale design. Those have yet to happen, mainly facing setbacks, but i'm rooting for them.
As someone who works nuclear field adjacent (and has pretty frequent convos with people working for Plant Vogtle, the plant that's nearly done adding 2 units in Ga) I completely agree about the expense. You can't do full scale nuclear quickly or cheaply enough for it to realistically compete over the short term. Honestly, somewhat rightfully so. I wish every industry had the regulatory hurtles to cross before they got to impact the environment. And they have to pay for their regulators.
As for SMRs, I'm also hopeful there. Mostly because of you could get a small enough one you could literally take it anywhere in the world and power a small town with ease.
there is one cool thing about nuclear though, if you know what you're doing they're ripe for government subsidy investment. One and done, they'll run for like 30-50 years. No questions asked. It's really just the upfront build cost that's the problem.
The georgia plant just opened 7 years late and 17 billion over cost. It is already running residents $4+/month in fees, with up to $13+/month being discussed, and that outside of the cost of electricity. It far, far over ran even huge government subsidies, with the feds putting up 12 billion.
There are much better places to put those billions now than in incredibly late and overly expensive "modern" nuclear.
To be completely fair to them, a ton of the delay was over lawsuits. I mean, you'd definitely end up dealing with those regardless of where you put upa NPP, but just giving them that small benefit f doubt there.
I'm a customer of theirs, paying the stupid fee. They got all celebratory about getting to the end and now the bill has to be paid and oh look, it's the customers paying. Joy.
I work nuclear industry adjacent, so I guess it's job security. And with that disclaimer I'll add this:
Building new plants is definitely going to take too long. If we get small modular reactors that will help. Same way if we get better batteries for solar and wind storage or new tech in geothermal. The simple point is that we are 50+ years behind. We gotta try anything and everything. It's our only hope at this point. And no matter what, it's going to cost. Money, land, your view from your backyard. People aren't willing to sacrifice anything to get it done, and that's how it's going to end for us if we don't change. And that's true for literally every problem we have. Nimby-ism will be the death of us.

most of that is going to be skill issues. "modern nuclear reactors" are multiple factors simpler than existing gen 2 and 3 plants. The problem is that they don't exist, and nobody wants to fund them right now.
If none of them have been built, then they aren't "modern" reactors. They are "theoretical" or "promising designs," with any improvements being just as "potential" as other unproven techs.
they are modern reactor designs, forgive me for not speaking like an autistic nerd who has a hyper fixation on weird shit for 12 fucking seconds.
They are modern reactors. Just like the RBMK is an old and antiquated reactor, even though they aren't being built anywhere. Same thing for BWR reactors, which aren't nearly as common as PWR even though they may be built every so often.
While renewables get build without subsidies, because they pay off anyway.
there are a lot of subsidies for renewables right now. They both have use cases, and different advantages. Nuclear is just particularly apt for the exact situation we're in right now.
As economists say, diversify investments.
You mean being in need of green energy as soon as possible? I don't see nuclear helping short term.
not immediately, but a very low carbon energy source that lasts for upwards of half a century? That's incredibly invaluable.
Especially if something were to plateau in solar or wind power for example.
