    Not all 7,000 construction workers would be working on the site concurrently. Different trades come and go depending on the phase of the project. So at first you’ll have the civil engineering earth movers come in, who clears the site and excavates the foundations. Then you’ll have the concrete crews come in who pour the foundations and do all of the concrete work. Obviously on a nuclear power plant there is a lot of foundation work, as well as a lot of above ground concrete so probably a good chunk of the construction workers will fall into this category.

    Power plants also have a lot of structural steel work, electrical and special equipment that would likey fall under the piping category but each of these uses a separate set of skilled labor that does not overlap.

    If you were going to actually try to build 3,300 nuclear power plants, you would rotate crews from project to project which would increase efficiency rather than hiring 27 million separate workers.

    In any case, I don’t think converting the world’s total electrical power generation to 100% nuclear is by any stretch of the imagination a good idea. Personally I think maybe 15 to 25% nuclear power generation would be a more realistic mix, similar to the US electrical power generation. The rest of the power should be solar, wind, hydro, wave and geothermal as they are absolutely cheaper to build.

      I’m not sure I agree with how you’d be able to execute on that level or organized construction safely, but I think we’re also reaching the “impossible-to-be-sure hypothetical” territory, so I’ll concede the point for now.

      I think my problems of cost and time still stand. It looks like adding rooftop solar with batteries to every building is still cheaper (on startup, and likely per MW) than nuclear plants. Regions that cannot support solar, onland wind, geo, or hydro can justify nuclear (at least unless shipping batteries or hydrogen conversion becomes cheap enough to compete), but I don’t think they amount to nearly 15% of the power needs in the world since they represent fairly distinctive regions with low energy demand.

        We do it all the time in the construction industry.

        For instance, Bechtel has 55,000 people in the US.

        “Since the 1950s, Bechtel has designed, serviced, or delivered 80% of all nuclear plants in the U.S… Bechtel has provided engineering and construction services for 88 of the 104 operating nuclear plants in the United States.”

        So just hire them. Too bad they lost almost all of their institutional knowledge about nuclear construction compared to what they used to have.
