But building new plants uses a shit ton of concrete. So we’re paying the carbon cost up front, and it can take years or even decades to break even.
That’s not remotely on the same scale, carbon-wise. Global output is like 4 billion tons of concrete per year, a nuclear plant uses like 12 tons per megawatt; an all-in nuclear buildout would use a tiny, tiny fraction of global concrete production and the carbon costs aren’t even remotely equivalent.
do you have a source for this carbon cost? i can’t find any figures about even the amount of concrete in a nuclear plant nevermind the co2 cost of that.
I do find a lot of literature that states that the lifecycle co2 cost of nuclear is on part with solar and wind per kwh so i find your assertment about the payback time being decades a little unlikely to say the least.
It’s the most expensive option so I’m not sure why people here are so keen on it. It’s much cheaper and faster to scale up renewable energy and in-fill with batteries and gas. Then phase out gas over time for a mix of things like pumped hydro, tidal, etc… This is already working in a lot of places and doesn’t involve long build times like nuclear.
8 years to build, not 30. Instead we are building many many more coal and gas plants. What a terrific alternative. Fallacy of renewables without storage is done. It’s never going to happen.
Long term nuclear is great…

So we can’t just spam build nuke plants right now to fix everything.
30 years ago that would have worked.

(also, wind power uses way, way more concrete)
Building any sort of new power plant uses a shitload of concrete, so that cost isn’t as dramatic as this would seem.
I think nuclear is dramatically overstated in terms of short term feasibility, but concrete use is not the reason why.
So would it be fair to say you have no concrete objections to the nuclear plan?
