Small modular nuclear reactors get a reality check in new report (newatlas.com)

[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."

Yeah, I just saw that news, which apparently happened end of last year. The public wants nuclear (or at least a non-coal base power), but projects keep getting delayed or scrapped due to local lawsuits or local governments pulling financial support.

Geothermal is cool, and apparently there's an active project. It should produce 400MW, which is pretty significant, but still a pretty small fraction of total capacity (~9.5GW).

If the Blue Castle project ever finishes, it'll supply ~1.5GW power. That, with geothermal, could take up ~1/4 of the total energy generation, which would be a really good start. I'd also like to see hydrogen production as a "battery" source (produce from solar, burn at night). Looks like that's under development as well.

Lots of interesting things are happening now, I just wish they started 10+ years ago...

Scrapping the NuScale project had nothing to do with lawsuits. Governments pulled their financial support because projected costs were exceeding what was contractually promised, mostly due to pandemic-related supply chain and inflation issues.

This is typical of nuclear. The industry wants to believe its problem is regulation. It's not, at least not if you want to have better safety guarantees than the Soviet Union did. Its problem is that to be safe, nuclear is expensive, and there doesn't appear to be a way out of that.
