A realistic understanding of their costs and risks is critical.
What are SMRs?
-
SMRs are not more economical than large reactors.
-
SMRs are not generally safer or more secure than large light-water reactors.
-
SMRs will not reduce the problem of what to do with radioactive waste.
-
SMRs cannot be counted on to provide reliable and resilient off-the-grid power for facilities, such as data centers, bitcoin mining, hydrogen or petrochemical production.
-
SMRs do not use fuel more efficiently than large reactors.

I know nothing on the topic, but the points you raise don’t seem relevant to me?
Yeah, economies of scale mean small things are generally less efficient than big things. This is a criticism of local power generation that applies just as well to wind turbines for example. Nothing to do with this idea really.
Why would anyone expect large power plants to be less safe than this? I’d expect the technology in both to be safe. Tell me if this is safe or not, not if it’s “safer” than large power plants on some ambiguous scale. Rooftop solar is also less safe than commercial solar power plants just due to being located near someone’s living space, but it’s a useless relative comparison.
That one is the only valid point to me.
Why not? Seems like they would.
This is just a repeat of the first point.
Again, I know nothing on this and don’t have an opinion either way. I’m pointing out this seems to be a criticism but only one of the 5 points seems to actually criticize this.
These are not my points, they come from the article. So for example in relation to your question on the
they have a couple of paragraphs that give an explanation.
My first issue with this, is that he’s still using his information from 2013. For instance, he claims that the spent fuel is just as dangerous. Yet we have proven time and time again, that the spent fuel rods can be used in other nuclear facilities to generate even more power off of them. We have the technology (theoretically of course, you need to actually build the facilities for this to work…) get even more energy off this “waste”, in turn also making it far less dangerous!
Second issue being he says the reactors would need a secondary power source in case of emergency. Duh? Thats his reason, is that they would need a backup power source to keep the coolant system running… Duh.
That’s actually a thing against nuclear power. For decades it’s the best thing. But often drawbacks are only solved in a new design that isn’t in a lot of nuclear power stations. And if they’re actually build then the cost overrun by a factor of 2 and more.
It’s always the next iteration that’ll solve things. It seems to be like a costly way to produce power if it’ll be built. Existing ones can be cheap, but then there are often several technical versions out of date.
Not to mention that nuclear waste is a ridiculously small problem.
France has mainly worked off of nuclear for 40+ years now, and the entirety of our nuclear waste takes about a swimming pool worth of volume… I think we should be able to handle that kind of output for a while.
