Off the Siberian coast, not far from Alaska, a Russian ship has been docked at port for four years. The Akademik Lomonosov, the world’s first floating nuclear power plant, sends energy to around 200,000 people on land using next-wave nuclear technology: small modular reactors.
This technology is also being used below sea level. Dozens of US submarines lurking in the depths of the world’s oceans are propelled by SMRs, as the compact reactors are known.
SMRs — which are smaller and less costly to build than traditional, large-scale reactors — are fast becoming the next great hope for a nuclear renaissance as the world scrambles to cut fossil fuels. And the US, Russia and China are battling for dominance to build and sell them.
I don’t think it’s astroturfing, it’s just cognitive dissonance. Lots of people were raised thinking that nuclear power was the future and they can’t let go of that. That’s why they downvote without commenting - there’s no factual case for new nuclear and that goes double for SMRs.
there absolutely is. It’s a good transitional source of power that we currently understand very well, and know how to manage, but simply cannot build. It would be a very prudent way of ensuring some “insurance” time before fusion starts being even remotely viable.
Although i don’t think SMRs are the correct answer here.
Not with the design and build times new nuclear has. It can take 10-15 years to build a plant, and during that time costs will usually spiral and schedules will slip. At the same time, renewables and storage will have gotten even more competitive.
this is true, but nuclear plants are slated to run for 30-50 years. France has been running their existing fleet to 50 years with maintenance extensions.
There was a recent plant vogtle, i believe, that was finished. Although if im not mistaken i think they just stopped midway through that one, it is up and running right now though last i checked, maybe not generating power yet but definitely running.
I’m guessing you’re referring to the flammanvile reactor project in france? If so thats an EPR design, which are horrendously complicated, and the vast majority of the issues present in the construction are the inability to pour concrete correctly, and the inability to weld correctly. Which is something that happens after 30 years of not building any nuclear plants. We quite literally just have to build more if we want to be able to use it.
It’s true that renewables are more competitive, but solar requires significant power storage figures, which can be problematic at best. Or require other production methods to take up the slack. Wind is quite good, but has the significant problem of waste. Turbine blades are a huge mess. That’s mostly due to industry pressure to make it profitable, and the push for it to succeed, which nuclear hasn’t seen. Nuclear just needs the same thing.
No matter which angle I approach the topic from, it always comes back to this:
“findings suggest that the cost per kilowatt (KW) for utility-scale solar is less than $1,000, while the comparable cost per KW for nuclear power is between $6,500 and $12,250. At present estimates, the Vogtle nuclear plant will cost about $10,300 per KW, near the top of Lazard’s range. This means nuclear power is nearly 10 times more expensive to build than utility-scale solar on a cost per KW basis.”

I just don’t see how this makes any economic sense. Sure, we could go all in on new nuclear and it would work fine but I don’t want to pay for that, I want cheap renewable power.
Then there’s this:

Building a plant with a lifecycle of 30-50 years seems like a bad idea when our world is getting more and more unpredictable. We’ve got climate change, we’ve got Putin fucking around with 6 reactors in Ukraine, earthquakes, tsunamis, human error, etc.
If a wind turbine catches fire, it’s not that big of a deal.
shits expensive because those plants are older, more complicated, and riddled with constructions issues. Literally all we have to do is just build more of them, and it will go away.
Or if that doesnt satisfy you, a one time government subsidy for the building costs will drastically improve it. (most of the cost is upfront after all.)
I’ve shown the data, there’s no economic case. Not to be an ass but your post reads like nuclear fanfic rather than a persuasive argument for new nuclear.
