Bill Gates Visits Planned Site of 'Most Advanced Nuclear Facility in the World' (gatesnotes.com) 204

Friday Bill Gates visited Kemmerer, Wyoming (population: 2,656) — where a coal plant was shutting down after 50 years. But Gates was there "to celebrate the latest step in a project that's been more than 15 years in the making: designing and building a next-generation nuclear power plant..."

The new plant will employ "between 200 and 250 people," Gates writes in a blog post, "and those with experience in the coal plant will be able to do many of the jobs — such as operating a turbine and maintaining connections to the power grid — without much retraining." It's called the Natrium plant, and it was designed by TerraPower, a company I started in 2008. When it opens (potentially in 2030), it will be the most advanced nuclear facility in the world, and it will be much safer and produce far less waste than conventional reactors.

All of this matters because the world needs to make a big bet on nuclear. As I wrote in my book How to Avoid a Climate Disaster , we need nuclear power if we're going to meet the world's growing need for energy while also eliminating carbon emissions. None of the other clean sources are as reliable, and none of the other reliable sources are as clean...

Another thing that sets TerraPower apart is its digital design process. Using supercomputers, they've digitally tested the Natrium design countless times, simulating every imaginable disaster, and it keeps holding up. TerraPower's sophisticated work has drawn interest from around the globe, including an agreement to collaborate on nuclear power technology in Japan and investments from the South Korean conglomerate SK and the multinational steel company ArcelorMittal...

I'm excited about this project because of what it means for the future. It's the kind of effort that will help America maintain its energy independence. And it will help our country remain a leader in energy innovation worldwide. The people of Kemmerer are at the forefront of the equitable transition to a clean, safe energy future, and it's great to be partnering with them.

Gates writes that for safety the plant uses liquid sodium (instead of water) to absorb excess heat, and it even has an energy storage system "to control how much electricity it produces at any given time..."

"I'm convinced that the facility will be a win for the local economy, America's energy independence, and the fight against climate change.

    This is exceptionally exciting. When is the plant going to start producing? Although I am philosophically a proponent of nuclear energy I've largely written it off since it seems that there won't ever be enough consensus to make it viable in my lifetime. If Bill Gates can actually get something exciting and new in nuclear power going, that would be the most interesting energy news in forever.

      HOPEFULLY, somewhere between 2028-2030. Sadly, it will probably be after 2030 since the goon squad continues to fight against the west building new nuclear power plants.
      That reactor (along with 2 fusion reactor) is currently in development less than 5 miles from my home. I keep hoping to bring my kids and/or are local school kids into the building and have them see the future.

      • That's what the thermal storage is for.

        Unlike the normal use of nukes in the US, this one should be able to throttle output conveniently to match need.

        • How many power plants have thermal storage? None.
          By switching coal plants to nat gas with the thermal storage AND have a hook-up area into that for the future reactors, it allows this part of the plant to be fully tested by the time that reactors are created and starting to be added.
          In addition, by having a nat gas boiler there, capable of doing this, it means that the power plant will have some of the best up time of any going.

        Hardly. The "goon squad" are not normally the primary causes of nuclear power overruns. The biggest issue for constructing nuclear since the 90s has been competence, quality, capability, and logistics. You can see that quite clearly in China. They don't have a "goon squad" since they can be magically disappeared by the government, yet still suffer major overruns and cost blowouts, (and a bonus point if your plant is operational for 1 year and then gets shut down for 2 years to fix shoddy construction that even regulators missed).

      If you dig through the links until you get to the details, it's not all that exciting. It's just a sodium fast reactor with an attached molten salt storage system that makes it suck less for demand following. When demand is low for its energy, it instead heats up the molten salt so that it doesn't have to reduce its output so quickly.

      We shall see in a decade or two if it's commercially viable. It's an interesting idea, using storage to make it more competitive with cheaper renewables, but of course if storage proves to be profitable/necessary the renewables will get it too.

      • Making storage more profitable will benefit all forms of generation. Eliminating the need for things like natural gas peaking plants just makes things more efficient overall.

    We should all be glad when we see people like Bill Gates investing in technologies which can have a positive impact on the world. He is a clever guy and has crunched the numbers and is very aware of the constraints. My opinion of Bill has improved since he left Microsoft as in that role he was absolutely ruthless.

    Developing reactors which can dovetail with the intermittent nature of solar and wind, burn spent fuel and nuclear waste and actually make more fuel than is consumed are sorely needed, and this reactor is one of the designs which actually can do this. Hopefully the costs associated with nuclear, where we see "nuclear" parts costing 10x the equivalent coal or wind generation equipment will also be solved. Given this cost differential there should be more opportunities to lower the costs of nuclear to become cheaper than other forms of generation.
    The bottom line is we need to find something which works. The scale of the issues associated with decarbonising the world economy are immense and frankly renewables can't do it and maintain the lifestyles to which we have become accustomed. Their energy return on investment is simply too low especially when combined with storage technologies. I don't want my children to live in energy poverty which is an approach advocated by many.
    Anyone who believe that renewables can sustain the world economy should actually do a little reading on the subject. They're an icing on the cake product, good for topping up the grid with cheap power which can be consumed by devices which have loads that can be done anytime like chlorinating a pool or heating a slab. They're not good for running an electrolyzer, powering aluminium refining or supplying power to a hospital.

      Indeed. There is a class of wannabe "engineer" that relies entirely on simulation and then believes they know everything about what they designed. These people have causes some spectacular disasters.

  • That stuff is so unreliable and dangerous it is staggering. And none of the massive problems so far would have shown up in simulation, because they were all due to unknown and hence unexpected material behaviors.

    Well, just like Bill Gates, the guy that delayed the information revolution by pushing bad quality software and missing the Internet completely for a long time, to push more bad tech on the world.

      Yeah I want a source on that. Cause I'm calling bullshit. The experimental breeder reactor II proved sodium cooling was reliable and super-safe.

        Bu that account, the Chernobyl reactor design is "super safe", because the prototype did not blow up. Same for the prototypes used for Fuckushima, TMI, and Windscale. Come to think of it, Windscale may not have had a prototype. They were so keen on demonstrating that they could compete with the US on nuclear weapons, that they just built that thing to make the plutonium and then justified it with lies o

          Your examples of sodium reactors failing were several non-sodium reactors. So maybe you need to get your head examined.

          By the way IFR's cannot meltdown. The physics prevent it from happening.

          • by gweihir ( 88907 )

            Nope. My examples were not about sodium reactors at all, obviously. They were about cases where the prototype appeared "super safe" and the production system was not. All that in the same industry.

            But I guess you are not smart enough to even understand such an advanced idea. Well, what can you expect. The only people for nuclear power at this time are idiots and no-moral people that stand to profit. Everybody else has moved on from this old, failed tech.

              No they weren't. Chernobyl was known not to be safe. TMI couldn't have hurt you if you were in the building. Fukushima resulted in 0 fatalities.

              The topic was sodium. So please provide examples of sodium reactors failing.

                The official death toll from Fukushima is over 2,300.

                https://www.asahi.com/ajw/arti... [asahi.com]

                1 is attributed directly to radiation exposure at the plant, the rest are attributed to longer term health impacts.

                Arseholes claiming that nobody died are both lying and helping TEPCO and the government avoid paying compensation to the victims. The legal battles to cover losses, to both life, livelihoods, and property have been long and extremely difficult.

          • by AmiMoJo ( 196126 )

            It's been tried before, e.g. Monju. The problem is that the sodium is corrosive, and it ignites if it comes into contact with oxygen, i.e. air. You get a fire and a hydrogen explosion.

            It also becomes radioactive. Half life is 15 hours, but obviously it's an issue if you have a leak. You can't use water to suppress the fire, that will just crease sodium hydroxide and make it worse. You can't have people anywhere near it. The only solution is a hydrogen explosion proof containment building.

          He knows not a single iota about nuclear energy. I wished /. had an ignore button.

  • That's fine, but have they simulated multiple disasters happening at once? That's what messed up the Fukushima plant - earthquake, tsunami, flood, power outage, all at once.

    • by gweihir ( 88907 )

      They will not, because that is impossible. They will have looked at some combinations they expect could happen (all nuclear disasters so far were unexpected things happening) and that is it. And then they just lie and omit that little detail.

  • because the computer simulations hadn't taken everything into account.
    Liquid sodium started to leak from inside the containment vessel and ignition when it came into contact with air.

    But Bill seems to think he can get it right this times as if it were are simple as bumping up a version number of Windows.

    Sodium fast reactors are difficult for a number of reasons
    The fuel density is higher so they are prone to faster reactivity excursions
    Fuel rods tend to be hotter an are prone to melting and deformation
    The coolant is flammable so leaks mean fires, vaporisation of the sodium can cause explosions if released.
    Liquid metal erodes can erode pipes and pumps.
    They tend to have positive void coefficients which means they require active excess reactivity dampening.

    However they do have a number of promising features.
    They can run at high temperatures,
    They can burn nuclear waste so it only needs to be stored for 300 years.
    They can generate fuel
    Sodium is a fantastic heat transfer medium meaning that you can remove heat quickly from the core.
    Sodium doesn't easily absorb neutrons and when it does it become sodium 24 which decays to Magnesium 24 a stable isotope.

    Personally I'd prefer to see the Terrapower's molten chloride fast salt reactor in operation as it has most of the positives of the sodium cooled reactor without some of the negatives.

    • by AmiMoJo ( 196126 )

      Only 300 years.

      It's worth pointing out just how much of an issue being sodium cooled is. In the event of an accident that sodium loop is critical. It's a huge problem if it leaks, because first you get a fire and likely hydrogen explosion, and then you have lost your primary coolant loop to stop the reactor melting down.

      One solution is a secondary backup water cooling loop. Of course that in itself is a problem, because when water and sodium meet you get hydrogen, and your reactor is probably already on fir
