'World's First' Grid-Scale Nuclear Fusion Power Plant Announced In the US (cnn.com) 49

Longtime Slashdot reader timeOday shares a report from CNN: If all goes to plan, Virginia will be the site of the world's first grid-scale nuclear fusion power plant, able to harness this futuristic clean power and generate electricity from it by the early 2030s, according to an announcement Tuesday by the startup Commonwealth Fusion Systems. CFS, one of the largest and most-hyped nuclear fusion companies, will make a multibillion-dollar investment into building the facility near Richmond. When operational, the plant will be able to plug into the grid and produce 400 megawatts, enough to power around 150,000 homes, said its CEO Bob Mumgaard.

"This will mark the first time fusion power will be made available in the world at grid scale," Mumgaard said. Virginia Gov. Glenn Youngkin welcomed the announcement, calling it "an historic moment for Virginia and the world at large." The plant would represent a new stage in the quest to commercialize nuclear fusion, the process which powers the stars. But the path toward it is unlikely to be smooth, not least because the technology has not yet been proved viable.

      The science is more or less settled. It's the engineering - turning theory and math into a real, working machine - that's been the big problem.

      Fusion is one of those things where there's no benefit to doing small-scale tests, since it's stupidly expensive and does not scale down well. If you're gonna do it, might as well go all out and build it full scale.

      Will this reactor ever be successful? I'd wager not, but I'd be happy to be wrong. Until then I'm not going to waste much time thinking about it.

          That's fission, this is Tokamak fusion, which has stymied ITER for years. What CFS claims is that they have massively improved the magnets and shrunk the reactor. What I want to see is a sustained Tokamak fusion reaction that lasts a long time and provides a net energy gain, which hasn't happened in any Tokamak generator - NIF (laser based) had a very short positive gain, EAST ran for ~20 minutes and had a net energy loss. Stellarators have had more promising results than Tokamaks, to be honest. The Lockhee

          That works for fission reactors, which is a mature technology. This is fusion. We still don't have any power-positive fusion reactors yet at all, of any size. They've constantly been ten or more years away.

      You do realize MIT made a breakthrough in fusion a year or two ago, had a long video on YouTube explaining exactly what they found, and all that information is available for your perusal, right? And there was an article here on slashdot, right?

      Fusion return is proportional to the fourth power of the containment field. By using modern superconducting magnets and some innovative design, they are able to achieve a much stronger confinement. This results in a longer, higher pressure burn (various, depending on which parameters you want to emphasize) that's more stable.

      Why people have to be snippy and insulting instead of just asking "what's the science behind this" is beyond me.

      Maybe it's an echo from the recent election, I don't know.

      Lots of informed people would just tell you what you want to know.

        (I'm about as pro-nuclear, including fusion, as they get)

        They've made compact superconducting magnets that theoretically produce enough confinement to sustain a large gain in power. They will probably break every record yet for fusion power gain, short of a hydrogen bomb. I'm very much looking forward to startup.

        However, there are a large number of unsolved problems before they have a commercial grade power reactor, as per the headline claims. So yes, this latest bit of hype is best treated with skep

SPARC (the experimental reactor that will nail down the last bits of science) is well on the way to being built. They need to break ground on ARC to make sure it follows in a reasonably timely manner.

          Or maybe it is the yearly "break-through" at Livermore Labs. Look, to make this work, somehow you have to efficiently extract energy from 1,000,000C plasma. We know how to get 55% or so from up to 3000C or a bit less. Most plants are between 300-600C. And remember, I said EFFICIENTLY. They can't even get to theoretical break even where you assume you can extract 100% of the energy as electricity. So we aren't even in the same order of magnitude of real commercial break-even yet.

        The breakthrough was in 2021, if I am not mistaken. And people are "snippy", because no one - including MIT - has ever had fusion generate enough power to even run the fusion generator itself. They have, occasionally, produce more power than went directly into the reaction, but power all of the equipment around it? Not even close.

        I'd love to see fusion power succeed. However, it has always been "just a few years away", and it continues to be "just a few years away". Even once they get the magnetic fields s

    Ah interesting: The US led on nuclear fusion for decades. Now China is in position to win the race

    The company [Energy Singularity] is planning to build a second-generation tokamak to prove its methods are commercially viable by 2027, and it expects a third-gen device that can feed power to the grid before 2035, the company said. In contrast, the tokamaks in the US are aging, said Andrew Holland, CEO of the Washington, DC-based Fusion Industry Association. As a result, the US relies on its allies’ machines in Japan, Europe and the UK to further its research. Holland pointed to a new $570 million fusion research park in eastern China under construction, called CRAFT, on track to be completed next year. “We don’t have anything like that,” he told CNN.

    There’s a growing unease in the US industry that China is beating America at its own game. Some of the next-generation tokamaks China has built, or plans to, are essentially “copies” of US designs and use components that resemble those made in America, Holland said.

    China’s state-funded BEST tokamak, which is expected to be completed in 2027, is a copy of one designed by Commonwealth Fusion Systems, Holland said, a company in Massachusetts working with MIT. The two designs feature the same kind of advanced magnets Energy Singularity is using.

      Context is important: The US had many of dead-ends that have been abandoned - Fusor [wikipedia.org] (electrostatic confinement)) designs (still very useful, but not as a power source) lead the way for quite a while. Fusors are easily built by hobbyists, even. There was some hope that the Polywell would bring electrostatic to net energy production, but it seems that hope is gone.
