[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."

Why can't we switch to thorium and molten salt instead? Much cleaner, much safer, same idea.

And even more expensive, no?

I didn’t think that was ready for commercialize yet. You have all the disadvantages of nuclear, but need additional development costs, need to implement a supply chain, then build out a new technology that is less efficient than existing nuclear, has unclear service life, may be supplanted by fusion or renewables, and you can still use it to make bomb material. Seems like a poor idea and a waste of money.

From India’s perspective, they’d get to lead in a new technology, where they have huge reserves of fuel, and cheap labor to scale up to a billion energy-starved citizens …. And if it helped increase their nuclear weapons stock in the face of tight controls on plutonium, so much the better

What makes you think it's less efficient. Normally high temperature reactor technology is more efficient not less.

So an interesting thing I've noticed people doing is basically claiming that whatever other side is being astroturfed by the "real evil", right. "Fossil fuel is funding renewable FUD of nuclear reactors!" or "Fossil fuels is funding nuclear FUD of renewables!". You can also see this with liberals claiming that anyone who disagrees with the DNC is a Russian bot, and with people who disagree with libs claiming that libs fund radical right-wing candidates as an election strategy and that this is one of the reasons why they are basically just as bad as those right-wingers.

The core thing you need to understand about this, as a claim, is that they can both be true. They can both be backed opposition, controlled opposition, astroturfing. Because it's not so much that they're funding one racehorse that they want to be their opposition, so much as they are going to fund both sides, plant bad faith actors among both sides, bad faith discourse and division, thought terminating cliches, logical fallacies, whatever, and then by fueling the division, they've successfully destroyed their opposition. The biggest help to the fossil fuels lobby isn't the fact that conversations about nuclear or renewables are happening when "we should be pushing, we should be in emergency mode, everyone should agree with me or get busted" right, as part of this "emergency mode" is us having these conversations. No, the biggest help to fossil fuels lobbies is the nature of the discourse, rather than the subjects of the discourse.

Also I find it stupid that people are arguing for all in on one of the other. That's dumb. Really, very incredibly dumb. Mostly as I see this discourse happening in a disconnected top-down vacuum separate from any real world concerns because everyone just wants to be "correct" in the largest sense of the word and then have that be it. Realistically, renewables and nuclear are contextually dependant. Renewables can be better supplemented by energy storage solutions to solve their not matching precisely the power usage curves and trends, but a lot of those proposed storage solutions require large amounts of concrete, careful consideration of environmental effects, and large amounts engineering, i.e. the same shit as nuclear. It can both be true that baseload doesn't matter so much as things like solar can more closely match the power usage curves naturally for desert climates where large amounts of sunlight and heat will create larger needs for A/C, and it can also be true that baseload is a reality in other cases where you can't as easily transition power needs or try to offset them without larger amounts of infrastructural investment or power losses. Can't exactly preheat homes in the day so they stay warm at night, in a cold climate, if the r-values for your homes are ass because everyone has a disconnected suburban shithovel that they're not recouping maintenance costs of when they pay taxes.

These calculations of cost offsets and efficiencies have to be made in context, they have to be based in reality, otherwise we're just arguing about fucking nothing at all. Maybe I will also hold water in the debates for money not being a great indicator of what's possible, probable, or what's the best long term solution for humanity, too, just to put that out there. But God damn this debate infuriates me to no end because people want to have their like, universal one size fits all top down kingly decree take of, well is this good or bad, instead of just understanding a greater, more nuanced take on the subject.

If you wanna have a top-down take on what's the best, you probably want global, big solar satellites, that beam energy down with microwave lasers.

Lemy has such a hard on against nuclear. I'm seeing reports by antinuclear think tank grifters shoved in my face almost daily...

For this particular design, they could have powered the earth by connecting turbines to the eyes of every engineer and project manager from us all rolling them in the back of our heads upon hearing “no cost overruns or delays”.
