    This is good news, relatively speaking.

    SMR technology is one of the most promising pieces of technological development in the nuclear power space.

    Standardized factory production and completely sealed, so refueling is only at the factory, never on-site. Their also, small, but scalable depending on the needs of each site.

    I’m not sure of the design this company is using, but I’m assuming they’re leveraging a fail safe reactor, as in, it requires properly running systems to generate fission, but if those systems fail, the fission process stops. There are no secondary systems that have to kick in, it’s a simple as either it’s running properly, or it can’t run it all.

    As opposed to systems like Chernobyl, or 3 Mile Island, that required separate active safety systems to guard against catastrophic failures. But if those failed, they’re backups failed, etc., well, meltdown.

      No, EVs alone require 10 times the current installed energy production. We’re not even close. Expect energy rates to quadruple. The price will increase until people can’t afford the commute with their entire day’s paycheck.

        EVs alone require 10 times the current installed energy production.

        No they don’t.

        The UK national grid estimates there needs to be a 4-5% increase each year, for roughly 15 years. That’s achievable.

        The US won’t be too different.

        Expect energy rates to quadruple

        Why quadruple. Where are you getting this from?

        The price will increase until people can’t afford the commute with their entire day’s paycheck.

            EVs are currently running partially on fossil fuel just fine and generating less pollution than ICEs because power plant efficiency is still better than combustion engine efficiency.

              That is nowhere near enough. It’s 33% versus 40% difference between co2/kWh . we need zero co2/kWh or else it’s all a waste of time.

              It’s only acceptable if we are transitioning to zero emission grid. If we stay on natural gas then it won’t even move the needle.

                We are transitioning towards it, but in the meantime, switching to EVs still reduces CO2 output and because the grid is getting cleaner, that means EVs get cleaner even after being manufactured and sold, whereas ICEs can only get cleaner through R&D and only get worse over time as they age (once they start burning oil, etc)

                  A few percentage points reduction in co2 emission isn’t going to move the needle. The whole grid has to shutdown fossil fuel energy production for this transition to make sense.

            In what world don’t they count?

            They can power EVs. And running an EV on fossil fuel electricity is still far less polluting than running a petrol or diesel car.

            One large generator at its most efficient setting is far more efficient than tens of thousands of small ones starting from cold multiple times per day, that aren’t necessarily maintained well, and are constantly going through their rev range.

            Where are your sources for any of what you’re saying?

              No , if you run EVs off a grid fossil fuel generator, that’s the difference between 33% and 40% efficient. It’s not enough to move the needle. It doesn’t even pay for itself in terms of emissions.

              The energy source absolutely has to be ZERO emissions as well. If not then it’s just climate cope.

                What the hell are you talking about? That’s not how people charge EVs.

                EVs on their own are typically 90%+ efficient. Although some are as low as ~85%.

                Even running on a generator, though, they’d still be more efficient than any ICE engine found in a car, aside from a Formula 1 engine.

                EVs are far cleaner, even if ran on a fossil fuel energy grid.

                  fossil fuel power plant are tops 40% efficient while ice powered cars are around 33%.

                  If you power you EV off a fossil fuel power plant, then that difference, minus the grid losses, the charging losses and then the inverter and motor losses, is how much co2 emissions you are saving.

                  Of course that’s assuming your driving habits don’t change, with that high upfront investment and relatively lower per mile costs compared to using gasoline.

                  And that’s not to mention the one time emission from the production of that EV amortised on its 15 year hoped-for lifetime.

                  Beside capturing government subsidies and the arbitrage saving from using temporarily cheaper electricity as fuel, I don’t see EVs making much sense either from an economic or a saving the planet standpoint.

                  Without a zero emission energy production as the source, EVs don’t make sense beyond hype and cope.

                  All fossil fuel electrical generation, and that includes natural gas, has to be shutdown. Or else it will not make a lick of difference.

    I have no issue with the safety of nuclear power plants, however: fissile material is no more renewable than fossil fuels even if it’s much greener. Also, in terms of more localized ecological damage, uranium mining is a disaster.

      Generally speaking renewables + storage are the cheapest way of generating non-polluting power.

      At variable scale, based on time of year and weather. Nuclear is much better for base-load, particularly at the scale of GWs. You know exactly how much electricity you’re going to get 24/7, and the fuel costs aren’t exposed to a market that can vary by 150-300% annually.

          Well one easy one, in my country it is that nuclear plants need to emit zero radiation from their core, like nothing. This is incredibly expensive to achieve, a more sensible value would have been similar or less than normal background radiation.

          Nuclear has a lot of advantages that are really low hanging fruit of producing safe clean energy that is perfect for a grids baseload.

              South Africa, you can read up on us if you want to learn about a country that really fucked up its energy supply, but that is a different story.

              You do need a baseload, this is not something an argument of saying we do not really need a baseload can wish away, industries that run 24/7 like a smelting operation where if you cannot shutdown, or hospitals or traffic lights, there is a certain percentage of baseload that has to be generated.

              Solar and wind are amazing and I really wish to see these systems play a major role in power generation, but you say the nuclear and coal plants are very inflexible. I do not know who this guy is but Nuclear and coal can very easily ramp up their power generation, both these are basically steam engines, both nuclear and coal can very quickly heat up and generate a lot more steam that powers generators, like an car engine but more accurately a steam train that you give more power to go faster. Solar and wind cannot ramp up on their own, cannot ask the wind to blow harder or the sun to shine brighter suddenly when the system requires it, they need costly backup systems like methane peaker plants or energy storage, be it batteries, pumped hydro, hydrogen electrolysis the list goes on. These things added to solar and wind plants are usually not allocated to the cost of generation, a total cost of generation including these additional backup systems are a better indicator of solar and wind systems cost.

              Now what about waste. I agree coal is messy and is causing global warming and needs to be phased out. But nuclear waste is a solved problem, it has been for decades, the spent fuel is usually stored deep underground where it will never interact with the world again. Solar on the other hand, if it costs about $20-$30 to recycle a panel but like $1-$3 to send it to a waste dumps, what do you think will happen to the solar panels. https://hbr.org/2021/06/the-dark-side-of-solar-power Harvard business did an article about how solar recycling has really been a point of weakness, where nuclear we have set guidelines on how to environmentally and safely dispose of nuclear waste currently. I am willing to bet you the environmental impact from pollution from nuclear, including all the disasters will be negligible compared to the waste impact from solar panels and batteries currently.

              So my point is not to dismiss solar or wind, really where wind and sunshine are naturally plentiful it will be a waste not to harvest these resources, just like where geothermal resources are available it will be wasteful not to utilise it.

              But nuclear, even with its high initial capital cost and long build time, still does provide energy cheaply and will last for a lot longer than solar panels and wind turbines, nuclear can be easily and quickly ramped up or down depending on the load required.

      Nope, they have a partner that’s doing that and the partner is going to be providing small modular reactors. Although we are not sure according to the article whether Google is going to be running them directly to their data centers or whether they are going to be providing energy to homes and buying renewable energy credits or something. Either way, small modular reactors should bring down the price of nuclear.

    Nuclear has never been profitable without massive government subsidies and guarantees, and Google Kairos too will either manage to collect those or lose money.

    It’s unclear how Google and Kairos set up the deal — whether the former is providing direct funding or if it just promised to buy the power that the latter generates when its reactors are up and running. Nevertheless, Kairos has already passed several milestones, making it one of the more promising startups in the field of nuclear energy.

    I guarantee you, they are shouldering on none of the risk (like the Chinese and French at Hinkley Point), and this startup will be going down.

          Let me preface this that I’m not a huge fan of nuclear, but I do like factual information.

          Could NOT get the nuclear power plant in Georgia off the ground for how long?

          If you’re talking about Vogtle, it took about 13 years and 14 years. (two reactors)

          Did it ever get finished?

          Yes. If you want to be specific the original two reactors were finished in 2008. The new work was for the other two reactors. That’s what took 14 years. Of the two new reactors, one started providing commercial power for the first time in June of 2023. The second new reactor only started providing commercial power in Feb of 2024.

          But when corporate wants it just fucking happens 🤡

          Different type of power plants between what is being discussed for Google and what was put in at Vogtle in Georgia.

          Vogtle was completing construction of an existing older design. Think of this like a bespoke tailored suit. It is crazy expensive, and only fits you.

          What most of these tech companies are going for is called Small Modular Reactors (SMR). Think of this as like buying a ready-to-wear suit off the rack. Its not nearly as fancy or as impressive (usually much smaller power generation), but its not custom made so its much cheaper.

        actually this (yes, I’m replying to myself). I’m an idiot with no marketable skills. I put boxes on shelves for a living. I want to be an artist, a musician, a programmer, an author. I am so bad at all of these, and between having a full time job, a significant other, and several neglected hobbies, I don’t have time to learn to get better at something I suck at. So I cheat. If I want art done, I could commission a real artist, or for the cost of one image I could pay for dalle and have as many images as I want (sure, none of them will be quite what I want but they’ll all be at least good). I could hire a programmer, or I could have chatgpt whip up a script for me since I’m already paying for it anyway since I want access to dalle for my art stuff. Since I have chatgpt anyway, I might as well use it to help flesh out my lore for the book I’ll never write. I haven’t found a good solution for music.

        I have in my brain a vision for a thing that is so fucking cool (to me), and nobody else can see it. I need to get it out of my brain, and the only way to do that is to actualize it into reality. I don’t have the skills necessary to do it myself, and I don’t have the money to convince anyone else to help me do it. generative AI is the only way I’m going to be able to make this work. Sure, I wish that the creators of the content that were stolen from to train the ai’s were fairly compensated. I’d be ok with my chatgpt subscription cost going up a few dollars if that meant real living artists got paid, I’m poor but I’m not broke.

          Imagine a future 2032 where all BTC has been mined ahead of schedule and Alphabet is the world’s largest lender after reorganisation into a banking platform.

    The article mentions Kairos Power but doesn’t mention that their reactors in development are molten-salt cooled. While they’ll still use Uranium, its a great step in the right direction for safer nuclear power.

    If development continues on this path with thorium molten-salt fueled and cooled reactors, we could see safe and commercially viable nuclear (thorium) energy within our lifetimes.

    https://www.abc.net.au/news/2024-09-06/china-building-thorium-nuclear-power-station-gobi/104304468

    To my layman’s knowledge, using thorium molten-salt instead of uranium means the reactor can be designed in a way where it can’t melt down like Chernobyl or Fukushima.

    Edit: The other implication of not using uranium is that the leftover material is harder to make in to bombs, so the technology around molten-salt thorium reactors could be spread to current non-nuclear states to meet their energy needs and reduce reliance on coal plants around the planet.

      If development continues on this path

      If we continue down the path of wasting energy and polluting to produce useless shit humanity is screwed.

        There is a whole universe of resources and our needs for them will never be fully satisfied. Every step towards cleaner, more sustainable energy is a good one.

      The meltdown that happened in Chernobyl happened because of mismanagement. Yes, there were design flaws in the system, but lots of rules had to be broken before the design flaws were triggered.

        Nah, mismagement happened yes, but any other nuclear plant wouldn’t have exploded, they used a old technology even for that age, for cust cutting or faster to build idk that’s why it exploded
