    Nah, the nuclear industry got a TON of R&D funding too, and continues to. Plus I don't think you realize just how much governments subsidize and assist nuclear power. $8-10 billion…

    So you're saying the 1% of people driving electric cars should pay for the climate change caused by the 99% that are not?

    Small reactors were part of the original 1st gen nuclear reactors. The world went to bigger reactors in the 60s-70s because it ended up being much cheaper than building lots of sma…

    China's nuclear industry and the way the government interacts with it is just... very different from pretty much any other country. This is true of some of their other sectors. Yes…

    Yeah, and there's not enough viable vendors in the nuclear sector to be able to just switch if someone does not play by the rules. You are correct that wind has a lot more flexibil…

    Passive safety is what you describe. That's a requirement for reactors to be classified as Gen III, so all of the models listed above have some variant of that. > eliminating the n…

    You're trying to argue that the solar market in 2020 looks the same as it did in the 1970s? Seriously? When the cost of solar PV has dropped 70% just in the last decade alone...? h…

    Click the link and look at the graph in my parent comment. Gas started rising in 2002, when wind and solar had an invisibly small presence in the US market. It sure sounds like you…

    Gas plants are replacing coal plants: https://www.power-eng.com/2019/04/11/eia-gas-fired-combined-... They're generally cheaper to run and better at load-following. Coal has been o…

    It's not looking so hot for SMRs right now though. NuScale, one of the most promising SMR companies, is losing backers for its first big reactor build. This is a result of cost und…

    Comment #25164944

    There's a reason countries don't build breeder reactors. Fuel costs are a tiny fraction of the costs for a nuclear powerplant: less than 10%. Breeders save a bit of money on fuel i…

    Wind is a pretty solid source of baseload actually, as long as you build enough. The supplementary materials from Caldeira's Geophysical Constraints paper (usually used to argue AG…

    Comment #25164455

    The reactors being built today are Gen III/Gen III+ designs: AP-1000, the EPR, VVER-1200/ AES-2006, APR1400, etc. These include all the design and engineering refinements we've bee…

    Nothing in there actually refutes my point that France wants to REDUCE its dependence on nuclear energy overall. France is the poster-child for a nuclear-focused powergrid. If they…

    This is... really off base for 2020. Solar and wind in the US are incredibly cheap sources of energy. Literally the cheapest options: https://www.lazard.com/media/451445/grphx_lcoe…

    Worth noting that Unit 3 at Olkiluoto in Finland was started before Flamanville and it hit massive cost overruns and delays as well. It was another EPR -- it's not like Flamanville…

    Yes, nuclear power projects bid below what they know it will cost and then pull a shocked-pikachu face when the final bill ends up several times the original "cost estimate". Look …

    You realize that World Nuclear News is not an unbiased source, right? The UK is doing fine with a renewables-heavy powergrid, as are Spain and Portugal. 40% of their electricity co…

    NuScale just lost a bunch of their backers for their project after announcing several years of delays and cost overruns. https://www.sciencemag.org/news/2020/11/several-us-utilitie…
