[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.”
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.
What? How? Far as i know it’s the most expensive, with a lot of hidden costs.
When costs are level per kilowatt over lifetime Nuclear is cheaper thanks to economies of scale, it’s only more expensive when plants are restricted by local authorities in how much they can produce in a given cycle so that other power generators in the energy sector can fill their contracts. When these artificial caps are removed and the plant is allowed to operate as intended and no kneecapped to allow coal and oil plants to operate at their peak effeciency rates, nuclear drops below .10USD. And thats using outdated equipment and maintaining the absurdly high safety standards saddled upon them despite being the safest form of power production bar none.
Wholesale or retail cost? Either way, that’s not especially cheap compared to renewables.
Nuclear may be cost competitive with putting solar panels in space at this point. Granted, that’s back of the envelope costs for a hypothetical space based solar system compared to nuclear plants that already exist. But the fact that they’re close is not a good sign for nuclear.
Plants will take 10 years to build, at least. If every permit was signed today, there wouldn’t be a single GW of this new nuclear going on the grid until 2034. We’re aiming for major reduction in CO2 by 2030. Oh, and the huge amount of concrete needed would create a massive spike in CO2 by itself. Timeline issues alone kill nuclear before it starts.
Edit: fixing autocorrect’s corrections
Extremely cheap per kilowatt? Every statistic out there that I’ve seen and that includes government funding, as well as construction and deconstruction costs, paints a different picture. Nuclear is only competitive with coal or the relatively underdeveloped solar thermal.

If you scroll down literally like. A paragraph past that you will see a very nice table showing the spread of nuclear costs. Some (including in the US, which is used for the EIA figures) are quite expensive, but others (notably South Korea) are very much cost-competitive or better than renewables. Also worth noting, the renewable estimates have spread themselves, and do not include overinstallation/storage required to behave as firm power.
Which is to say:
A - there certainly are quite a few places that nuclear doesn’t make sense, at least currently. Including the US
B - equally, there are a lot of places around the world where nuclear is competitive
C - we should perhaps look at why the US is so expensive relative to other countries; it’s not some law of nature, we can change it. And it’s probably not just because other countries under-regulate them (I’d buy that for some of the countries listed)
I specifically picked the statistic that claimed to have included the full cost of installing something new. Most other statistics only include prolonging the life of existing plants, thus ignoring the installation costs completely. You can just quote the paragraphs that prove your point the same way I have and then we can discuss further. Maybe I made a mistake, who knows.
The real advantage of nuclear is it’s constant output of power compared to the variable output of solar and wind
The space based nukes paragraph is irrelevant. While I agree with the point thtat it may not only be useful for long term space habitation, it may be required, I don’t see what that has to do with earth based commercial power generation. They’re very different beasts with little overlap. That’s like saying you support corn based subsidies, because we’ll have to grow crops off world: true but not relevant.
