    That might very well be the case. I certainly think it plausible, maybe even likely. The next step would be to get a better sense of that.

    The government offered 4 guaranteed loans to build nuclear power plants (about a decade ago).

    Not one company stepped up. Why not? That seems ominous. It proves noting at all, but why did they all find this too risky? It's worth asking, if we are to honestly discuss the economics of nuclear power.

    Nuclear power plants are extremely long lived assets. Corporations are often reluctant to make very long term commitments to hard infrastructure in what they see as a relatively volatile market (energy). Note that new refinery construction hasn't taken place in the U.S. in decades either.

    True, and I see your point, but their capacity has been upgraded, and new ones are planned for Texas. Where are the new nuke plants?

    "Many nuclear plants are aging nearing the end of their lifetimes. Nine nuclear plants (five that have closed since 2013 and four that plan to retire within ten years) represent over ten gigawatts of generation and approximately ten percent of total U.S. nuclear capacity. They face high operating costs and competition from cheaper gas and renewable energy sources, making the business of running many of the nation’s nhttps://climatenexus.org/climate-news-archive/nuclear-energy-us-expensive-source-competing-cheap-gas-renewables/early 100 nuclear plants unprofitable

    Nuclear had its day....that day has passed.

    Would such reactors be anywhere near big enough ?

    The two reactors on a Nimitz class aircraft carrier produce around 200MW. The proposed Hinkley Point C power station will have two reactors each producing 1630MW. You'd need 16 ships to provide the capacity of a single power station.

    A vessel moving at 4 knots will move 96 nautical miles (110 statute miles) in 24 hours.

    Placing large nuclear reactors on floating barges is a really bad idea. Placing them on the sea floor, far away from tectonic plate boundaries, is a somewhat less bad idea.

    Fine. I'm sure that sea going reactors could be scaled up. Where would be good points to dock them at?

    Big Oil is already asking the federal government to build massive seawalls to protect existing refineries.

    To me that indicates that new refineries have to be entirely redesigned as to locations and the civil engineering that goes into them. But I think that can be done, just pay more at the pump.

    Nuke power on a floating marine foundation? idk, very difficult sell.

    I think it would be a very good way to get around local opposition to nuclear power plants. As I said you very seldom see protests in the U.S. about American Navy nuclear powered vessels docked in a port city. And there have been hundreds.

    Nuclear powered carriers have a good record. Nuclear powered submarines and nuclear powered ice breakers not so good.

    Okay...then no where. The problems with the concept have been clearly explained to you with no rebuttal so the entire idea is dismissed.

    American built ones have an outstandingly good record.

    Why not a thorium reactor?

    but they are ageing and decommissioning is a bitch

    The Savannah River Project is still being cleaned so companies have to account for those costs even after the reactors have been shut down.

    You do get that every spent fuel rod is one step closer weapons grade. The more reactors, the closer we get to No. Korea having more nukes then Israel.

    I'm pretty certain that nuclear weapons grade uranium is not made out of "spent" fuel rods. A uranium based nuclear weapon (a very primitive design by the way, most are made with plutonium) uses uranium far more enriched than any used in a commercial nuclear power plant. By an order of magnitude.

    Do you know how they have wind farms? What about current farms?

    Line the gulfstream with a network of large impeller which will each rotate a turbine.

    As far as off shore nuclear power plants. I think that bad weather could make a barge sink or something.

    So it's best to have a permanent submersible structure to avoid the bad weather on the surface. Like a giant submarine with no propellers. You can make it super big because you dont have to worry about propulsion.

    Fill tanks up with water to make it sink during bad weather
