Google Inks Deal With Nuclear Company As Data Center Power Demand Surges (cnbc.com) 51

Google announced it will purchase power from Kairos Power's small modular reactors (SMRs) to support its clean energy goals and data center demands. The company did not disclose the financial terms of the deal. CNBC reports: There are only three SMRs that are operating in the world, and none in the U.S. The hope is that SMRs are a more cost-effective way to scale up nuclear power. In the past, large, commercial-scale nuclear reactor projects have run over budget and behind schedule, and many hope SMRs won't suffer that same fate. But it is uncharted territory to some extent. Kairos Power, which is backed by the Department of Energy, was founded in 2016. In July, the company began construction on its Hermes Low-Power Demonstration Reactor in Oak Ridge, Tennessee. Rather than use water as the reactor coolant -- as is used in traditional nuclear reactors -- Kairos Power uses molten fluoride salt.

Google said the first reactor will be online by 2030, with more reactors going live through 2035. In total, 500 megawatts will be added to the grid. That's much smaller than commercial reactors -- Unit 4 at Plant Vogtle, which came online this year, is 1.1 gigawatts, for example -- but there's a lot of momentum behind SMRs. Advocates point to lower costs, faster completion times, as well as location flexibility as reasons. Monday's announcement is another example of the growing partnership between tech companies and nuclear power. Data centers need 24/7 reliable power, and right now nuclear is the only source of emissions-free baseload power. Many hyperscalers have ambitious emissions-reduction targets, which is why they're turning to nuclear power.

    The strange part is that a normal large power plant would make more sense for data centers. They want a lot of power, they want it cheap, and stable. There's really no need to scale it down.

    I'm guessing they're trying to side step punitive regulation put in place by anti-nuclear activists with goal of preventing new nuclear power plants from being built. Which was quite successful across many Western nations.

      Yup!

      One of the impacts of regulation is that it changes. Building a large plant takes years and while it is being built regulations change. While the plant is still being built, the plant has to make changes to align with the new regulations. There is a long post on Medium or Substack about this. The article tries to nail down why the US is one of the most expensive places to build nuclear power. Changing regulations is a major cause.

      If one could bang out a dozen modular reactors in the time it takes to build a single large one, it is a huge win.

        Funny how it’s “changing regulations” in America, when we just call it “fucking corruption” everywhere else. There’s a reason nuclear builds have been met with every form of red tape in America. Because we allow that corrupt shit to happen. Every fucking time.

      • Building a large plant takes years and while it is being built regulations change. While the plant is still being built, the plant has to make changes to align with the new regulations.

        Having worked on nuclear projects before I have to say, no this is false. Not only do most regulations get frozen for project development at the approval stage, the nuclear industry is infamous with its insanely INSANELY slow update for regulations. There's very little recycle back to engineering phase. Not zero, but not significant.

        But then the entire story begs a question.

      It's an attempt at reassuring investors of continued growth while also saying they're being real about global warming.

      Google are hedging their bets is all. After all, this AI thing is seriously wasteful on electricity. Worse than Bitcoin.

      The reality is renewables are going to supersede SMRs for baseload capacity before they can be realised. Renewables will even push hydro offline in the end.

      The theory behind SMRs is they can be built on factory production lines rather than custom building them in situ. That promises to reduce the production costs by a lot and improve reliability, enough that it's worth it to give up some economies of operational scale.

      Another assertion is risk mitigation is a lot easier with a flock of smaller reactors instead of one big one. The mess you need to clean up is a lot smaller if one reactor fails. Hopefully this makes licensing easier and faster.

    Bill Gates, Sam Altman and Jeff Bezos have all backed nuclear companies.

    There is money to be made if it works. But a power purchase agreement, assuming that's what this is, doesn't guarantee it will ever produce any power. The larger issue with all these plants is who is responsible if anything goes wrong. With plants attached to the grid the ratepayers are responsible, but I doubt Google or Microsoft are taking on that liability here.

      It's a good deal for Google. Someone else already paid to build and operate the plant through the expensive period. Now it's just subsidised energy from an operator that is probably finding the market increasingly difficult at renewables ramp up. All the risk is externalized too.

    • Hydro (and geothermal) are emission-free baseload power.

      Both of them have geological requirements that make them hard to scale up much more than they are currently being used:

      Hydro means damming a river. Good luck getting approval, considering we're celebrating the removal of dams in California [ca.gov].

      Geothermal means drilling for access to hot strata. I don't know much about it, but if it were cheap, easy, and available in lots of places, we would have more of them already, right?

      • Hydro (and geothermal) are emission-free baseload power.

        Geothermal is not emissions-free. Radioactive elements come out of those vents. When the vents are enlarged and production eventually wanes then they add water (usually primary treated sewage water) to the system in order to restore it. This causes more emissions as more matter is flushed loose. Most of them escape into the atmosphere, but some collect on the turbine blades. At The Geysers geothermal field near Calistoga, CA, the world's largest operating geothermal plant, what was washed off of the blades

    • nuclear is the only source of emissions-free baseload power

      Hydro isn't emission-free baseload power?

      No, neither nuclear nor hydro is emissions-free. The only measurement that matters when talking AGW is cradle to grave, and both nuclear and hydro have higher emissions per Wh than solar or wind. When you flood an area for a reservoir you create anaerobic conditions which cause CO2 and methane release, and the building of the dam including the CO2 emissions from the concrete (and of making it in the first place) is a CO2 emitting process.

      Hydro actually has ongoing emissions due to the decomposition process

    • Hydro isn't emission-free baseload power?

      It largely emission free is once operating. Construction might be another issue. How much CO2 was emitted making the concrete for the Three Gorges dam? Hydro, however, comes with it's own unique set of environmental costs. And we seem to have dammed all the rivers we're willing to dam so it's difficult to envision scaling it up by much. Damn.

    • I think there is excess hydro available from Canada. The Klamath River dams that were just removed didn't produce much power. There are climate effects from hydro and the problem of reservoirs producing carbon emissions is one of them. But then solar and wind aren't totally emission free either if you consider the manufacturing process. Neither is nuclear power. The idea of emission-free anything is probably fallacious.

    Good luck to Kairos but they don't even have a pilot plant up and running. The NRC gave them a permit to build a 35-MWth “non-power” demonstration unit last year, and it is "anticipated" in 2027. And sure, if they ever do produce actual power, Google will probably buy some.

      It's using molten salt, which is dangerous and corrosive stuff.

      I'd be amazed if they ever got anything working, even a prototype. Investors look at it, a little demonstration non-power device in 3 years time, then some unknown period before they can scale up to something that actually makes money. So much risk of issues with the technology, no clear benefits, a

      • Looking at their website, it's an old concept that they hope will magically be cheaper and better by being smaller

        Unfortunately what the SMR companies are finding is that being smaller actually makes them significantly more expensive. The industry's economies of scale isn't defined by how many units are produced, but how much power you get per reactor. Even with the best case estimates for SMRs they will never have economies of scale that will drive down construction points, these things will never roll off a factory line en-mass with any foreseeable estimate of current or impeding technological developments.

  • Will rampant use of AI/LLM wreck the world before the proliferation of small (inefficient, vulnerable, questionable economically and ecologically) reactors does?

    Hand in the back of the classroom goes up excitedly. "I know, I know! The AI will hallucinate a reactor design that will solve all the problems at the same time, and then do my homework for me and get me a cool job at Google powered by the reactor!!!"

  • Getting geeky for a bit, the Kairos design [kairospower.com] uses a two stage heat exchanger. Any speculation why? Seems that would add complexity and cost. What is the reason to not create steam directly from the salt coming from the reactor?

    I'm also curious how one shuts down and restarts a molten salt system. How do you melt the salts and get them flowing through the pipes? How does one preheat the plumbing so the salts don't freeze when you introduce them? And how do you go about shutting the reactor down, letting it coo
