    However, I didn’t come away from her videos with the belief that nuclear plants are particularly cost effective or that Thorium is some sort of magical tech, but more that if we want to get away from fossil fuels yesterday, then we need to be ramping up all forms of alternative energies in parallel with each other, and that we should have been building new nuclear plants 10 years ago, but the second best time is today.

    The name of her actual video is “Is nuclear power really that slow and expensive as they say?”

    She say “does it actually take a long time to build?”, then cites the article here where she highlights the yellow average:

    …but then she COMPLETELY IGNORES what I circled in red thats on the exact same page about Vogtle power plant which is the most recent plant built in the USA which suggests its data is most accurate. Instead she looks at a difference source cited in the article which goes back in time to 1976 to early 2000s for data instead of 2023 data of Vogtle:

    Its one thing to not have the data, but to intentionally ignore data citing in the article your criticizing and cherry picking old data in my mind is intellectually dishonest.

    And again she does this:

    Why are you skipping the 2023 data Sabine?

    Here she’s mixing lots of old and new data to arrive at the “median time for nuclear power plant construction in the USA”. I’m not sure how thats a useful metric when you’re incorporating 50 year old data.

    This is especially true because we don’t have to model the data, we have a real life recent example with Vogtle:

    “Two additional units utilizing Westinghouse AP1000 reactors began preliminary construction in 2009, with Unit 3 being completed in July 2023.” source

    So no, Sabine, we shouldn’t think it takes 91 months but instead what it actually took which was 168 months.

    She says “in the 1950s they built them much faster in 21 months”. Great! So now we’re using 75 year old data instead of 1 year old data to make our point?

    Then she gets to costs and says “it takes $5 to $10b to build a nuclear power plant in the USA”

    Okay so Vogtle (again the most recent data) was in this neighborhood for cost? Nope not even CLOSE:

    “In 2023 costs had increased to $34 billion, with work still to be completed on Vogtle 4” source

    It just gets worse the longer the video goes on.

      I don’t have time to read all that just now, but I feel like focusing on the singular most recent reactor’s build time is cherry picking. What’s wrong with looking at decades of data of build time and costs? Costs can be normalized for inflation and markets, and average build times are much more important than a single reactors’s build time even if it is the most recent one. I don’t get why you’d focus on that single reactor. How are you so sure it represents some new average?

        Because the next most recent reactors are many decades older. The next most recent project would likely be Watts Bar plant which started in 1973 and finished one of two reactors online in 1996 (23 year construction project!!!) or its second reactor which also started in 1973 and came online in 2016 an astounding 43 years from construction to being online.

        To remove THAT “outlier” you have to go back 1989 a full 35 years ago. If you’re going back that far, doesn’t that raise the question “how many more recent modern nuclear plant projects in the USA do you have to ignore before you get favorable numbers?”. If the more recent project keep taking way more time and costing way more money, why would we expect a project starting today to match what occurred in the 1970s instead of what happened in the 21 century?

        Costs can be normalized for inflation

        True

        and markets,

        Which markets? Electricity prices?

        and average build times are much more important than a single reactors’s build time even if it is the most recent one.

        That assumes that we could still build them like we did many decades ago. The knowledgeable people that ran those projects retired and weren’t replaced. Additionally, regulatory rules and safety rigor are much higher than they were back then negating that build time/cost from back then.

        I don’t get why you’d focus on that single reactor. How are you so sure it represents some new average?

        I don’t understand why drawing data from 35+ years ago is considered more accurate than data obtained in the last 20.
