Yeah, the best time to start building nuclear plants was 20+ years ago. Unlike most things, the second-best time is not now, however - we're at a point where the massive expenditure for nuclear power generation is just a big question mark as to whether it'll be cost-effective by the time it's finished. There just haven't been enough breakthroughs in the past few decades to improve the cost-effectiveness of nuclear power substantially, while renewables are faster to install, cheaper to replace, and advancing at a rapid clip.
Definitely should still keep any nuclear plants we still have running, though. My home state of Maryland generates over 1/3 of its power through a nuclear plant. Would be 2/3s if the Obama administration didn't screw us over 'foreign' (EU) suppliers being a 'security risk' back in 2010 or so, ffs.
No advancements?
Is SMR a joke to everyone?
Look, I'm not saying nuclear is the only path forward, far from it. I don't think any path is the only path forward. I believe that we'll need a compilation of various generation methods to meet the demands of tomorrow.
The only thing I want to see in that future is no coal, nor fuel plants. Those two are the most common types of greenhouse gas-producing plants in use. The objective, in my mind, is to entirely phase them out. Whatever gets us there, is good with me. If that turns out not to be nuclear, that's fine too. If SMR or any other kind of nuclear is required to make that a reality, that's also fine.
I. Don't. Care.
Yes, because it hasn't really been demonstrated to be particularly viable. You don't need tons of small reactors, that's way too much logistical and regulatory overhead for little capacity. And you need way more auxiliary infrastructure and personnel that way, driving up costs that exceed what you save by modularizing them.
I love the idea and the potential of SMRs, but the comment you’re replying to said there weren’t sufficient advances to make it economically competitive. That’s true.
Any time I see a new graph of the cost per kwh for the several largest power generation types, the SMR range makes me sad. I’m sure a bunch of the smarter timelines are getting 80% of their power from cheap, mass produced, passively safe, self-contained SMRs installed individually in remote areas or in large banks near population centers. But for our dumb asses it seems so far off economically. (Granted that’s because fossil fuel power plants don’t cover the costs of their externalities, but that’s also how our stupid world works)
