    Just like assuming a perfectly spherical cow, or a frictionless surface, you can completely ignore the economics, the massive cost and schedule overages to make nuclear work.

    Flamanville-3 in France started construction in 2007, was supposed to be operational in 2012 with a project budget of €3.3B. Construction is still ongoing, the in-service date is now sometime in 2024, and the budget has ballooned to €20B.

    Olkiluoto-3 is a similar EPR. Construction started in 2005, was supposed to be in-service in 2010, but finally came online late last year. Costs bloated from €3 to €11B.

    Hinkley Point C project is two EPRs. Construction started in 2017, it’s already running behind schedule, and the project costs have increased from £16B to somewhere approaching £30B. Start up has been pushed back to 2028 the last I’ve heard.

    It’s no different in the US, where the V.C. Summer (2 x AP1000) reactor project was cancelled while under construction after projections put the completed project at somewhere around $23B, up from an estimate of $9B.

    A similar set of AP1000s was built at Vogtle in Georgia. Unit 3 only recently came online, with unit 4 expected at the end of the year. Costs went from an initial estimate of $12B to somewhere over $30B.

    Note that design, site selection, regulatory approvals, and tendering aren’t included in the above. Those add between 5-10 years to the above schedules.

      Gee, I wonder if the cost might go down if we built more of them, as is the case with, y’know, basically every other complicated thing that humans build.

        So even if I follow your logic, that nuclear plants will get cheaper and faster to build, wich I’m not, you still have to build the first generation of plants slow and expensive. So we either wait 15 years to get better at building those plants, or we just build renewables right now.

          We do both. This isn’t a binary choice.

            So what happens when you finish pouring the concrete in 15 years and the demand has already been satisfied by renewables? Concrete production alone accounts for ~8% of global emissions.

            I am not anti-nucleur, I wish we invested more decades ago.

              Well demand isn’t going to go down, and we’re going to have to replace all of the old power plant plants anyways, even if they are solder or wind. Everything that we build has a lifespan, and the United States has a heck of a lot of legacy power plants that are going to be decommissioned over the next 100 years regardless of what type of plants these are. Solar, wind, hydro, coal, gas, nuclear… Nothing lasts forever.

        Except throughout the history of nuclear power it has always gotten more expensive, regardless of time period, learning curve, adoption curve, or any other variable you care to consider. Solar, wind, and batteries have always gotten cheaper and continue to do so.

          Is there some reason for that? What makes nuclear power fundamentally different from all other human undertakings?

        Yes that is exactly what would happen. To do that though, you really need state funding, state approval, and a secure supply chain as well as experienced engineers, management and construction and supply chains.

      I think this is the most overlooked aspect, besides it never being in time to do any good for the crisis we are in now.

      I believe, the increasing cost and loss in efficiency compared to alternatives will always be an issue for NE to be out-priced by solar and wind (Dunai, 2019; WNSIR, 2022). These cost will eventually come back to the end user.
      Most definitely the reason why nuclear advocates want the government to give securities and don’t dear to be the entrepreneurs they claim to be (NOS Nieuws, 2018). Please give me some welfare state, but I’d rather have some more solid solutions.

      Costs. Levelized Cost of Energy (LCOE) analysis by U.S. bank Lazard shows that between
      2009 and 2021, utility-scale solar costs came down 90 percent and wind 72 percent, while
      new nuclear costs increased by 36 percent. The gap continues to widen. Estimates by the
      International Renewable Energy Agency (IRENA) has seen the LCOE for wind drop by
      15 percent and solar by 13 percent between 2020 and 2021 alone. IRENA also calculated that
      800 GW of existing coal-fired capacity in the world have higher operating costs than new
      utility-scale solar photovoltaics (PV) and new onshore wind (WNSIR, 2022).
