[T]he report’s executive summary certainly gets to the heart of their findings.
“The rhetoric from small modular reactor (SMR) advocates is loud and persistent: This time will be different because the cost overruns and schedule delays that have plagued large reactor construction projects will not be repeated with the new designs,” says the report. “But the few SMRs that have been built (or have been started) paint a different picture – one that looks startlingly similar to the past. Significant construction delays are still the norm and costs have continued to climb.”

Nuclear technologies missed their window. The use cases where they are the best technical solution now are extremely limited, and that means you can get the investment going to improve them.
It’s a curiosity now.
There’s an alternative timeline where Chernobyl doesn’t happen and we decarbonize by leaning on nuclear in the nineties, then transition to renewables about now. But that’s not our timeline. And if it were, it would be in the past now.
From where I stand you couldn’t be further from the reality of the situation.
Nuclear has a number of advantages from low carbon output per kilowatt over lifetime as well as being extremely cheap per kilowatt.
But the real advantage being overlooked is the small foot print and land use compared to other forms power generation. A nuclear reactor is ideal for high density population areas, adding no pollution like fossil fuels and using a fraction of the land that renewables require. And there is room for overlap between renewables and nuclear as well, meaning days where wind or solar would produce more power than usual, its easy to scale back solar production to take advantage of cheaper power, and vice versa for times when renewables aren’t going to generate enough to meet demand nuclear can increase their output relatively quickly and effectively.
The future of nuclear is however one of the most important. We are eventually going to be spending humans to other planets, and having mature, efficient and compact forms of power generation with long lifetimes and minimal start up power from idle states is going to be important, solar gets less effective the further from the sun we get, you can’t stick a wind turbine on a space craft and expect good results, and you’re out of your mind if you want to burn fossil fuels in an oxygen limited environment.
Treating nuclear as more than a curiosity but rather as the genuine lifeline and corner stone of our futures and future generations is significantly more important than fossil fuel profits today and all their propaganda.

They are still going for big building size reactors that have site specific details even if the core is built in a “factory”. This still doesn’t scale well.
I wonder if it can be economical to go smaller still and ship a reactor and power generation (TRG maybe or a small turbine) that then doesn’t require much other than connecting wiring and plumbing and its encased in at least one security layer covered in sensors if something goes wrong its all contained. Then its just a single lorry with a box you wire in. That has a chance of being scalable and easy to deploy and I can’t help but think there is a market for ~0.5-10 KW reactors if they can get the lowest end down to about $20,000, it would compete OK with solar and wind price wise.
I suspect no one has bothered because the regulatory overhead means it has to be big enough to be worth it and like Wind power scales enormously with the size of the plant. But what I want is a tiny reactor in my basement, add a few batteries for dealing with the duck curve and you have something that will sit there producing power for 25 years and a contract for it be repaired and ultimately collected at end of life.
You can sort of do this today using the Tritium glow sticks and solar cells but it doesn’t last long enough and the price is not competitive. Going more directly to the band gap in a silicon or something else semi-conductive and a long lived nuclear material could maybe get a little closer price wise.
You want people to have their own private nuclear reactor in their basement?
Nukeheads are insane
I sympathized with your statement immediately, but then after thinking about it for a bit, most people basically have controlled pressure bombs (gas-water boilers) and buildings filled with gas pipes that can (and have) wiped out whole city blocks.
It’s still not a good idea, obviously, but localized fossil fuels are also ridiculous when you think about it.
Nuclear waste and fuel is dangerous for years and is an invisible hazard. Propane and gas at least only explode once
Thoughts on CO from malfunctioning boilers?
The two aren’t even part of the same conversation.
It builds up for days even months and is an invisible hazard?
Edit: Changed introductory wording to be less belligerent. I am sorry if I have caused a significant level of offense.
Just wait for the nuclear shills to flood in and claim that nuclear fission is a sustainable and necessary form of power generation.Some people claim that nuclear fission is a sustainable and necessary form of power generation. It is not. Uranium extraction devastates entire landscapes, the construction of nuclear power plants is too expensive (even for SMRs, as the article explains), ergo electricity prices will climb, it is a hugely wasteful use of so many tonnes of concrete (concrete manufacturing is heavy on the environment too), it creates waste that will still haunt us for hundreds of thousands of years (finding geological structures that are guaranteed to be stable that long is difficult), and relative to the initial construction and set-up effort, they don’t provide that much energy. We already have methods that can provide us plenty enough electricity that are entirely sustainable by leveraging large-scale atmospheric aerodynamics as well as the largest nuclear fusion reactor at our disposal (the sun). There’s simply no need to go nuclear.I hate that the conversation is happening on these terms. I hate that we have a bunch of opinionated online “teams” on this issue.
Hey, you know what we need? All of it. Any sort of energy generation that lowers atmospheric emissions in any way we do need. The concept of “nuclear shills” shouldn’t exist, the concept of “solar shills” or “hydrogen shills” or “fossil fuel shills” shouldn’t exist. The entire conversation is a PR battle by energy corps to get people to buy into marketing so they can get governments to back popular choices so they can get expensive contracts for large infrastructure work.
I hate that we have online keyboard warriors overrepresenting the challenges of one of the contributors to lowering emissions while underrepresenting the challenges of others. Hey, do you think nighttime generation and storage is an issue? Maybe installation costs for domestic solar generation, the state of the grid or the uneven distribution of solar power yields on different territories? Because I do.
And I do think cost and build times for nuclear generators are a problem (which makes it confusing that some countries are dismantling plants that seem to be working safely and are within their expected lifespan, but I digress).
And I do think the impact of hydroelectric power in nearby areas is a problem.
And I do think the open questions for geothermal are a problem.
And I do think the issues with cost, storage and dirty generation of hydrogen are a problem.
And I do think we should be working on all of that. At once. This isn’t kids arguing about which game console is better on the backyard, this is a massive existential issue, and would be even if we weren’t dealing with a climate change ticking bomb. This report? It’s bad news. Any report that tells us any of the ideas we have for weaning off fossil fuels is not working as well as we expected is bad news. Can we all get with that program?
All good points, and I’m all for pretty much any technological research, but
And I do think cost and build times for nuclear generators are a problem
Thorium is another form of fission generation that has not been commercialized yet. In the real world, maybe it will be better, or maybe it won’t. But fission generation already takes too long to build out, so why switch lanes to a different form of fission generation that also needs more time and money to be commercialized? Nuclear uranium fission generation had its growing pains over the years, as the technology found challenges to address and areas to improve, but thorium has not yet gotten far enough to run into those so there will be additional challenges requiring time, money, further development
If those were decades ago when the future was bright for fission technology, I’d be all over this. However the future is dark and cloudy for fission generation, nightfall may be approaching. The advantages of thorium are not enough to shine a new light, there’s not enough room for improvement to save fission generation, this is just an expensive detour.
This is nonsense. Like someone else said we will need some kind of nuclear power for future space exploration. There are parts of the world that are dark for six months of the year, and plenty of places that don’t get enough light for solar to be practical.
Most renewable sources are not consistent enough to be used by themselves, and battery storage isn’t practical with current technology. Then there are the concerns with hydro power and biomass and how that affects the environment. I have even been told by leftists that biomass shouldn’t be installed as it destroys too many native forests.
Of course the actual best solution is one we don’t have the technology for yet: things like nuclear fusion or neutrino capture.
For the record, I disagree with you both and this narrative is also part of the problem in my book. Screw the futurism and longermism of “we need nuclear power for space exploration”. We’re not talking about that. We’re talking about mitigating runaway climate effects and filling the blanks of an alternate energy mix by using complementary tech.
Absolutely let’s keep working on nuclear power. Absolutely let’s keep working on battery storage, and potential energy storage and thermal storage and wind and geothermal and whatever else we can come up with. And absolutely let’s abandon whatever doesn’t work or is made obsolete, starting with no longer burning hydrocarbons as soon as we can stop.
There’s this air of erudite dilettantism about this chatter that just pisses me off. People sitting by and idly projecting their sci-fi fantasies about colonizing planets or about a fully solar powered planet and feeling smart about it. Given the short-term, impending human cost of this issue, both for climate reasons and for energy scarcity reasons, that just feels gross at this point.
What do you disagree with me? I was trying to back you up up here saying that yes we need nuclear in addition to all the other technologies. I am not saying that you shouldn’t use solar, just that it isn’t applicable everywhere on earth.
Screw the futurism and longermism of “we need nuclear power for space exploration”. We’re not talking about that.
You should be talking about that. After all climate change is also a future problem. Staying on a single planet isn’t safe even if you eradicate climate change, war, disease, and just about everything else. There is pretty much nothing stopping a gamma ray burst or stray blackhole, or any number of other things from killing everyone on this planet. Like yeah climate change is a high priority, but it doesn’t make all other issues go away.
Look, I’m just trying to impress something very specific here and I can tell I’m not getting through.
I’m not here to call out people arguing for or against one or another type of energy generation. I’m complaining about the discourse about this being about long term hypotheticals and optimal solutions when we should be in emergency mode.
It’s like we’re in a burning building and people are having arguments about the cost per year of different types of fire extinguishers. But if I make this point about someone criticising nuclear power it comes across as me “siding” or “shilling” for nuclear power, same if I do it when someone argues against solar power.
But I’m neither. I’m arguing for practicality and immediate action. Because we need it now, not because I just finished reading the Dune books and have some really neat ideas about generation ships.
The problem is that “both” isn’t a valid option unless a country has unlimited finances.
Otherwise you have to decide on what’s the most feasible option and then renewables win big time
I sometimes feel as if the current push for atomic is from the fossil-lobby as they are aware that it either works and they get 10-20 more years to sell oil until the reactors are built - and even if it doesn’t work out it still will slow down rollout of renewables
If you have 100 billion to spend on energy producing you have to choose if you want to go all-in with one source or split it up which would move the end of fossil fuels Back further
Not to mention having to buy the radioactive materials from dictatorships and having problems to cool down the reactors with rising temperatures and rivers running dry
I just don’t see how atomic isn’t a huge gamble that can backfire hard (and I’m not even talking about catastrophic events like Fukushima)
Most countries have unlimited finances. They only have limited real resources like labor, concrete, copper, glass, etc. The fact that we still don’t understand this and behave as if the metadata of the economy accurately describes reality puts artificial brakes on the solutions of many problems, climate being one of them.
The problem is that if a country treats money as unlimited and without a cost then inflation will mirror that and people in that country will lose their savings, their job will not pay for their bills anymore and so on
It’s not as simple as “just spend more”…
Inflation is a symptom of the lack of some real resource. There are many parts of the economies of many countries where there’s unused production capacity which simply “turns more natural resources into more stuff” if more money enters that part of the economy, without producing inflation. It’s not “just spend more”, it’s “spend as much as you can on things that you want done, which aren’t limited by real resources.”
I found Randall Wray’s lectures on the topic to be eye-opening. If what I wrote sounds strange, and it might, I highly recommend watching some of them. There are a few recordings on YouTube.
Lemy has such a hard on against nuclear. I’m seeing reports by antinuclear think tank grifters shoved in my face almost daily…

Maybe you should spend more time outside. Every flavor of nuclear has worse approval ratings than most dirtbag politicians.
I’m seeing reports by antinuclear think tank grifters shoved in my face almost daily…
Why do you think you need to PAY people to oppose nuclear? After seven decades of cockamamie “this time it’s different” schemes most people just moved on.
Woa bro I was saying hard on but this is a full on raging erection maybe you should deal with your frustrations
I’ve seen opinions very strongly in both directions on here. I’m very pro-nuclear, but the largest issues they face is always bureaucracy. It sucks that an artificial thing is what’s stopping then usually, but it is true. We need some protections to keep things safe, but it seems too harsh for nuclear compared to the dangers it presents opposed to the dangers of other power sources.
Absolutely, and it’s by design by candid admission of environmentalist organizations and green parties. Their objective was over regulating the industry beyond any rationality and they succeeded.
