      The good news - it’s online, generating clean power, and hopefully demonstrating the safety and benefits of modern nuclear plants.

      The bad news - it’s $17B over budget (+120%) and 7 years behind schedule (+100%). Those kind of overages aren’t super promising for investors, but perhaps there are enough lessons learned on this one that will help the next one sail a little smoother.

      Either way, good to see it can still be done in the US.

        I wouldn’t call it “clean power”. We still don’t have a good solution for the nuclear waste.

        Edit: Downvotes because I am not religiously defending a technology and pointing out that there are downsides (EVERYTHING HAS DOWNSIDES!). Too many people from reddit here already.

          We do, Japan, France have been doing it for years. It’s forbidden in US due to the fear of the material being used to make nuclear bombs.

            Aha … : https://www.reuters.com/business/environment/france-seeks-strategy-nuclear-waste-site-risks-saturation-point-2023-02-03/

            The plan, called Cigéo, would involve placing the waste 500 metres (1,640 ft) below ground in a clay formation in eastern France.

            Construction is expected in 2027 if it gets approval. Among those opposed to it are residents of the nearby village of Bure and anti-nuclear campaigners.

            Burrying waste is not exactly clean. Yes, they reduce the waste. But they are also hitting limits and have challenges in increasing capacities.

            In spite of the war in Ukraine, which has made many in the West avoid doing business with Russia, EDF is expected to resume sending uranium to Russia this year as the only country able to process it. It declined to confirm to Reuters it would do so.

            That is also not really cool. I also find it a bit shady that something is only doable in Russia. That sounds a bit like it’s only possible there, because they ignore safety rules any other country would have in place and we don’t care because “now it’s their problem”.

              For what I’m been reading online, that would be a waste of perfectly functioning nuclear material: check Nuclear reprocessing.

              It a material remains radioactive means it still has energy in it, so the goal should be using it to the maximum. SMRs for example, might use reprocessed nuclear material at their core.

            Yes nuclear power plants are very expensive. But the energy density is phenomenal.

            Energetic armortisation is far quicker on a nuclear plant than on solar panels.

            And the argument of subsidies is usually a fake one, since governments also pour millions into renewable energies.

            Broken down to lifetime cost to the cost of comparable technologies, nuclear is still on the same level as solar and wind.

            Since I am from Germany, and German sources might not be ideal to share, let me explain it this way: People are not stupid. They will never choose the financially unwise option, if the other one would seriously be the better one.

              People do often act stupid, but you are seeing it from what I consider to be an incomplete perspective. Nuclear could be financially unwise overall, but someone would still get a payday. That 17B over budget wasn’t burned and unmade, it went into the pockets of the people organizing and building the power plant.

              All this to say, the huge majority of the people involved in making the power plant a reality weren’t motivated by the efficiency of the power production on a cost basis. Most of them were probably making more money while it was still being subsidized, planned, and built. And while I think subsidies are generally useful and good, they can be a vector of financial abuse when it comes to unprofitable industries.

              Lastly “lifetime cost” is a bit of a useless metric when the majority of that lifetime comes too late. No point to a power source that will cleanly produce power after it has meaningfully contributed to pushing us over the edge and past the breaking point for a climate that can support agriculture as we know it. There isn’t enough time or margin for error in emissions left available to build all the nuclear plants needed to meet energy demands.

              Can you find any recent analysis that supports your claim that nuclear costs are at the same level as solar?

              The only one I’ve seen suggest this was from a nuclear industry lobby group, and it inflated the costs or solar by insane amounts.

              In Australia this is a bit of a hot topic and all impartial estimates suggest that nuclear will not get close to renewables in any way, even taking into account storage and grid costs.

              In the 10 years since this single reactor was built, one of our states has transitioned to almost 100% renewables. Wholesale costs have plummeted, but renewable projects are still profitable in the market. I was involved in a reactor project in a western nation some time ago (it’s still being completed unsurprisingly), and the lock-in wholesale price to support that project was simply extortionate. Solar generation prices are a whole magnitude smaller.
