> Wind and solar will probably be cheaper but this kind of tech could still be very useful in quite a few places. I agree, and I would love to see SMRs succeed. But, the latest developments in the cost of NuScale don't get my hopes up very high. Related, I have no idea if UNSC is going to go anywhere, but I really like their website[0]. Probably the best SMR company website in existence. [0]: https://www.usnc.com https://www.usnc.com

Cost estimates for novel nuclear designs have a track record of being all but worthless. I wish I could dismiss your pessimism but the flip side of the economics, that’s a large part of what makes this so difficult, is that if they do succeed and make SMRs a real thing the cost could go down dramatically.

  This was also an interesting and relevant analysis if you want to read more on the subject: https://cleantechnica.com/2023/01/18/the-nuclear-fallacy-why-small-modular-reactors-cant-compete-with-renewable-energy/ https://cleantechnica.com/2023/01/18/the-nuclear-fallacy-why... Like I said, I do hope that SMRs succeed, and I want them to succeed cost effectively, not just by subsidization.

  There's a lot of pressure on the industry to emphasize that the designs are "new" and not like ones that failed. Innovation is good, I think, but the reason nuclear is even in the conversation now is because it already has been done, mostly safely, and could be scaled with existing tech. This makes it a decent player for a transition energy source. High cost shoot-the-moon future designs hopefully will never be necessary. I say this as an absolutely fervently pro-nuclear person. Comparing France and Germany is really all the information you need for this kind of case. But I don't understand this push for small reactors outside of niche military applications etc.

    Small reactors are being pushed because new big reactors in the US are stone cold dead. This is why I call them HMRs, "Hail Mary Reactors". They're nuclear's last desperate chance in the US.

      Without their big constituency in the USDoE mandarinate, SMRs would be equally dead. DoE grants overwhelmingly favor thermal energy sources and storage, probably just because thermal conversion is what they are trained in.

      I think you’re maybe wishcasting. The state and federal governments are spending billions to keep Diablo Canyon open after a rush of blood to the head thinking they could close it.

        I meant of new nuclear construction. Keeping existing plants open is something different.
