ITER Fusion Reactor Enters Existential Crisis 470

deglr6328 writes "The long beleaguered experimental magnetic confinement fusion reactor ITER is currently in what some are calling the worst crisis of its 25 year history. Still existing only on the paper of thousands of proposed design documents, the latest cost estimates for the superconducting behemoth are soaring to nearly 20 billion USD — roughly twice the estimates from as recently as a few years ago. Anti-nuclear environmentalist organizations have seized upon the moment as an opportunity to use the current global economic crisis as a means to push for permanently killing the project. If ITER is not built, the prospect of magnetic confinement fusion as a technique to reach thermonuclear breakeven and ignition in the laboratory would be in serious question. Meanwhile, the largest laser-driven inertial confinement fusion project, the National Ignition Facility, has demonstrated the ability to use self-generated plasma optical gratings to control capsule implosion symmetry with high finesse, and is on schedule to achieve ignition and potentially high gain before the end of the year."

      Don't be fooled it is frightening.
      Nuclear fusion is pretty much a potential infinite source of clean electrical energy and we have 2 options to try to master plasma confinement long enough to harvest that energy. One is investigated with ITER and the other is the inertial confinement. I don't think anyone has the authority to tell whether one or the other is more likely to be successful because it's very new and to test it you actually have to build huge tokamak reactors that cost billions and it has not been done before.
      So as Pascal I'll assume it's a 50/50 draw.
      Now put that piece of news back in context : humanity is maybe about to give up on half its chances to secure a clean source of energy for the forseable future.

            You have out-obtused me, I have little idea what your localities share in common.

            Do you mean to insist that they lack the money or stability to operate nuclear plants? That isn't exactly entirely attributable to fission itself. And Toshiba wants to sell them safe, small scale, self contained nuclear generation. The U.S. could be tasked with providing the islands with power, the U.S. Navy has long experience safely operating floating reactors (money is an issue there, but if we want to 'continue living in a civilization', we might have to stop worrying about it so much).

            I'm about evenly split on governments spending $20 billion on new fission generation vs fusion research, but I'm not very optimistic about fusion, mostly based on the numbers in a recent Scientific American article:


            The engineering requirements for the jacket on a tritium consuming fusion reactor are 'hilarious'. There is no better word. The targets for laser ignition also present 'interesting' production challenges. Meanwhile, uranium reactors 'fucking work', with political problems preventing them from being built, not fundamental technical challenges.

        Two options? This isn't US politics; there are a number of methods by which we may achieve fusion, and no doubt, more will be imagined. The main problem, is that nothing outside of the two methods you mention have received serious funding.

        Here are a few other methods, all of which hold promise for solving the energy crises. We should know within a few years which are practical.

        Polywell []
        Magnetized Target Fusion [] (General Fusion)
        Colliding Beam Fusion/FRC (Tri Alpha Energy)
        Dense Plasma Focus []

        Even if none work out, their combined cost is a pittance compared to the funds being poured into ITER.

          I am a physicist. Out of that list the only one that doesn't need a pretty enormous piece of magic is option 2. In fact its the best bet for a fusion dark horse out there. It requires no magic, other than a stable plasma (harder than it looks).

          Polywell needs entropy to go away. The probability of scattering is *much* higher than fusing, hence you need to pump in more energy than you get out. You can arm wave all you like. There is a lot of *experimentally* verified theory to back up that it won't work. The assumption that it will, would require that a *lot* of different experiments to get completely different results (and to still be getting different results).

          The same experimentally verified theory that dooms polywell, also dooms colliding beam fusion. Again we would see vastly different results from many different experiments over the years if it would even be within an order of magnitude of working. The probability of scattering is still much higher than the probability of fusion. It is just a fact of nature. The probability of fusion is really low.

          Note that you don't even need to go into xray losses to show that the previous options can't work. But xray losses make the problem totally untenable. And if you want the device to be smaller than a planet, you are going to need elections around hot ions. The hot ions will heat the electrons and you will get xray losses. Run the numbers and it looks pretty bad for all currently proposed exotic fusion devices. Many people who like the exotic options just pretend that these results don't apply, without any justification or experimental data. It doesn't work that way.

          The Dense Plasma Focus is interesting. If they would stick with DT fusion or even DD fusion they have a fighting chance and no magic would be required. However he keeps pushed B-p fusion in a thermal plasma. And to suppress the xray losses you need mega-Tesla fields. That a bit of magic. However the issues is not just ignored or sweep under the carpet like proponents of other devices. He does know about it and is theoretically trying work the problem.

          The good news is that he is testing with DD first. If you can do B-p, DD fusion is easy by comparison, and would be the energy breakthrough of our age. If you can do DD fusion you can do DT even easier and with much higher power density. It would be all gold. This is dark horse option number 2.

          Personally its crazy that we rant on about the future with global warming and stuff. Talk about multi-billion dollar carbon credits, bail out failed banks to the tune of hundreds of billions, and then can't fund a 20 year project 20-40billion over the *lifetime* of the project.

          And yes, i propose we have serious money going into both fusion and fission research *now*, so we have options to choose from later.

              What evidence? The published results have been nonexistent to no positive results. In fact all the current results show that the rest of the physics community is correct. There is also quite a bit of data on this sort of thing, its not as new as some think.

              , and the Navy continues to fund it.

              They also funded cold fusion. The navy giving funding to something is not a vote of scientific merit.

              Dr. Nebel is responsible for continuing Dr. Bussard's Polywell research, and has made it clear that there are no show stoppers thus far.

              And is there any published data? Any published papers? Anything other than a media PR press release?

              Anyway, the electron scattering and xray losses turn out to be considerably less than one would expect in the Polywell.

              Well all the data on this i have seen does not suggest this at all. In fact the losses look about right from theory. Massively higher than the fusion yield.

              Furthermore, it is not a thermal system, so much of the conventional wisdom does not apply.

              Got anything other than an assertion to back that up. Because I have data, and some pretty well tested theory that says this is not the case.

              It isn't that entropy needs to go away, but it doesn't play a big part at the timescales in question. (ie. it doesn't thermalize quickly enough to matter, and there may even be a mechanism which prevents it from thermalizing.)

              Since fusion requires a *collision*, and thermalizing is via *collisions* this is quite false. You can't change the fact that the probability of scattering is *much* higher than the probability of fusion. This means that thermalization is the faster process.

              I'm not sure what experimental counter evidence you are referring to, as this is a rather unique system which has not been studied elsewhere. It is also a computationally intractable problem, so there are no shortcuts in this case.

              Both statements are incorrect in any practical sense. First the Russians have worked on this stuff. Buzzards original paper even cites them. They developed the idea of virtual electrodes in a plasma. Also the system is as far as collision process are concerned, similar to other electrostatic confinement methods. They get fusion easily, but fail at anything other than a neutron source.

              The polywell is quite tractable numerically in any practical sense. If its not, where are all the predictions coming from? We can simulate tokamaks with some degree of success. The plasma parameters of a polywell make it easier, not harder.

        Okay, but the problem is that if you think you need successful regulation to prevent a BP spill-like disaster, then you still kinda don't understand fusion power.

        The problem with the BP spill is that once a problem occurred and oil leaked, the oil does what it naturally does and continues to be pushed out by the pressure underground. The problem with fission reactors is that when the control rods fail, the enriched uranium does what it naturally does and continues to release neutrons in a chain reaction.

        When a fusion reactor fails, the fusion stops on a timescale that to human eyes would be called "instantly". The whole reason nuclear fusion is such a hard thing to make into a power source is that it takes so much damn effort to make the source material actually fuse because that is not it's natural state until you get enough of it in one place that you call it a star. It's inherent in the nature of the power source that it can't go out of control. "Out of control" means "stopped".

        I'm an environmentalist, but also pro-fission. Yet I do think concerns about regulation of fission reactors are valid. How worried am I about regulation of fusion reactors? None worried.

      Since I've been through 50 posts and haven't seen a reasonable answer....

      First let me say that I'm very much in favor of nuclear power generation, so even though I think fusion has an environmental cost, other options are often far worse.

      There is no such thing as clean energy. An environmental cost must always be paid.

      • Fusion reactors would be powered by a deuterium-tritium reaction. Deuterium is plentiful, and can be extracted from water for little more than the energy and facilities cost. Tritium is more problematic. It's radioactive with a 12 year half life. Most reactor designs are not entirely closed cycle, so some of that tritium will escape. Fortunately the escape rate will be small in normal operations. A larger problem is that currently most tritium is obtained from fission reactors. Maintaining enough fission reactors to generate enough tritium to fuel fusion reactors might be infeasible in a fusion only world so other sources have been suggested.
      • The first source is lithium, which, when bombarded with neutrons undergoes fission into tritium and helium. Since the D-T reaction generates neutrons, there are plenty of neutrons in a fusion reactor to support this reaction. Most designs suggest molten lithium as a coolant. The most likely disaster in a plant of that variety is a lithium fire. Lithium is very reactive, and hot molten lithium would burn upon exposure to air or water. Any breech in the cooling system would likely start a fire. The fire would release T2O, THO, LiOT and Li2O (which will decompose to lithium hydroxide from atmospheric water), so you've got nearby toxic effects from lithium and you've released radioactive water (in small amounts). Also, Lithium must be mined, refined, and processed, which required industrial processes that are not clean.
      • Because it would be continuously bombarded with neutrons, the structure of a fusion reactor would become as radioactive as the structure of a fusion reactor. Although because of the smaller atomic weights, the half lives of the elements involved are mostly shorter than those in a fusion reactor. So you're talking 500 years before its safe rather than 10,000 or more.

          Easy? No. What follows is a lot of statistics I pulled from a lot of sources. I can't footnote them all here, because it would make the post hideously long and unintelligible.

          The largest desalination plant on the planet is the Jebel Ali Desalination Plant in Dubai, United Arab Emirates. It is scheduled to go online this month. The estimated cost construction cost is $550m USD and requires 2,000MW of power. It houses 8 desalination plants, each capable of producing 17.5m gallons of water. The power plant will cost another $1.7B USD. There was also a 400/132kW substation built for the project, at a cost of $60m USD.

          Operating costs for the project cannot yet be determined, however in the past about 45-50% of the operating costs of a desalination plant was energy costs. Right now, a coal-fired base plant costs about $1.6-2m per MW of output. For simplicity and to low-ball our estimate, we'll say that it costs $1.6 per MW. $1.6m x 2k = $3.2B USD, or a yearly operating cost estimate of $6.4B

          Total construction cost: $2.31B USD.
          Water purified daily: 140m gallons
          Operating costs: $6.4B/yr
          Cost per gallon per day: $0.13

          Now, let's assume that we had to switch to desalination and purification of potable water in this country. The per capita usage of water in the United States from 1996-1998 was 160.6 gallons per day. We'll ignore any adjustments or looking for more recent data in the interests of getting a ballpark estimate. The current estimated population in the US as of July is ~310.2m. That means our yearly use of water is somewhere around 49.82B gallons of water, per day. To purify that much water using desalination would cost us around $236.4B USD per year, just in maintenance costs.

          Still think desalination is "easy" ?

            Your main error is here:

            Operating costs for the project cannot yet be determined, however in the past about 45-50% of the operating costs of a desalination plant was energy costs.

      "Anti-nuclear environmentalist organizations" is just hand waving propaganda. *Which* organizations took *what* positions?

      Insofar as fusion power is concerned, its certainly a myth that environmental organizations are holding us back. Nobody knows what a commercially viable fusion plant would look like, so how could those mean old environmentalists be spoiling everything again?

      Now as an environmentalist myself, when we get to the point of building the first fusion power plant, I'd like to see a proper environmental impact analysis done, just because we've never built one. Surely we'll have to deal with the issue of plant decommissioning. Also, before we decide that fusion power is going to replace everything, we should think through the consequences to see if we've missed anything. But insofar as fusion will be replacing fossil fuels, the bar for "do no harm" is pretty low.

      Insofar as fission is concerned, I'm not against further research and a conservative program of new plant building. What I'm against is jumping to the conclusion that a crash program building the kind of plants we built thirty years ago is going to magically solve all our problems. There's be a lot of problems with uranium dependency, and we'd be storing up problems for the future.

      What I'd really like to see if more investments in the electricity distribution grid. This will prepare us for a future in which we have more diverse energy sources. That would be good for the country, good for humanity and good for the environment. Combined with greater energy efficiency and conservation, that would help us face declining global oil production without resorting to rash and desperate measures.

    green parliamentarians who believe that ITER is too costly and too speculative to warrant support. Rather than spending money on nuclear fusion, the greens would like to see ITER's funding spent on near-term renewable energy sources.

    ITER is terribly expensive. Combined with a substantial risk that the project could fail to produce valuable results, it seems that asking hard questions and investigating alternatives for that investment is a wise move.

      I dispute your assertion that my phrasing was ad-hominem. Greenpeace's current stance on the matter is thus: "Governments should not waste our money on a dangerous toy which will never deliver any useful energy" Sortir du nucleaire's stance is that ITER is a hazard "because scientists do not yet know how to control DT reactions", a statement so laughably stupid I don't even know where to begin with it.

      ITER is terribly expensive.

      Compared to what? The LHC cost around 9 billion and isn't expected to have any real tangible benefit to anyone other than the knowledge. The cost of a couple nuclear reactors is about 10-14 billion.

      Compared to that, this thing sounds CHEAP. These "anti-nuclear activists" need to start asking themselves what we're going to replace base-load power generation with. Sorry, but wind just isn't going to do it since the wind doesn't blow all the time. Unless they like fission, coal, or natural gas, I don't see what else is going to substitute for generating a base load power. This is really a long term investment, and even though it's not guaranteed, we need to pursue multiple different strategies. Betting on one horse is just stupid.

      Yes, Polywell is "unconfirmed" as to whether it can really work. Just like Focus Fusion, and Cold Fusion (which probably isn't even fusion as such, but some kind of effect seems to be happening), and all the other alternatives that are struggling to scrape together a shoestring budget -- they're all going to be "unconfirmed" until somebody spends some money to confirm or refute them. Now we see the folly of pouring tens of billions into one experiment while letting all the others starve.

    ITER, Europe -- Physicists at the ITER Fusion Reactor announce new physics particle, known as the Existention. Previously only observed being emitted by cats placed in trap boxes filled with deadly acid, the creation of synthetic Existentions will open up a whole new line of research in quantum bogodynamics. An anonymous source close to the research team said it happened when the tight jeans worn by one of the research assistants distracted the operator of the reactor, causing what she loosely termed a "man event".

    Is the Polywell, which uses inertial electrostatic and magnetic confinement. And if physicists cared about actually giving the world nuclear fusion power they would cease work on the futile ITER project, which at this point is little more than a jobs program for some nuclear physicists, and start work on the Polywell fusion device, which only needs millions of dollars to be proven correct, not the countless billions that have been squandered on the ITER.

    • Electrostatic fusors spend all their input energy just getting the nuclei to collide. There's very little room for improvement, of which the Polywell stands the best chance of the entire class. But the Navy would have it in every boiler room if it already worked.

    "Anti-fusion environmentalist organizations" I wonder who that is exactly? Care to name one? I took a quick look at the referenced article, and all it said was "the greens", which I assume means the Green Parties in Europe. If that is the case then why didn't they say so? Note that they did not say explicitly any Green Party member or refer to any specific Green Party platform.

    So now we have a mysterious un-named evil anti-intellectual, anti-rational, anti-scientific pressure group. How much power do these evil mysterious trouble makers have? Are they completely in control of whatever organization that they are in? Are there any other people in these groups that are in favor of fusion research? Is there any debate about the relative merits of fusion vs. other non-fossil energy sources among the "anti-fusion environmentalist organizations"?

    The article referred to is in Nature, the prestigious British science journal. Do you think that they have any self interest in this debate? What are the chances that they would support the ending of a major scientific research effort in Europe in any circumstances? It's not that they are corrupt, but there is no question what side of the issue they will support.

    And look how the Slashdot hoards start barking like a bunch of dogs who just caught a cat when they have a chance to trash "environmentalists". Some quotes:

    "Having them argue against a *fusion* project pretty much proves that these idiots are not qualified to remember to breathe, much less protect the environment."

    "The hard greens don't like what we do with power."

    "All progress must stop so we can, um, stay in the financial crisis forever?"

    Yes, according to the Slashdot Pundits, all environmentalists are the same: irrational anti-scientific scum who want to drive the planet into a new dark ages because of their ill founded personal vendetta against rational thought. No shades of gray here. No possibility that environmentalists can have various opinions. No possibility that there might be people in the environmental movement who are pro-fusion.

    For all the pretense that Slashdot readers are rationalist who use there intellect to examine all sides of an issue, all I see here is a bunch of prejudiced morons who are more interested in thumping their chests and screaming insults at a perceived enemy then actually thinking about issues. You are exactly the same as the people who you construe as your opposition: irrational pigheads who cling to their preconceived notions and would rather make baseless charges then engage in meaningful discussion.

    Sigh, I normally don't want to bother commenting on articles that have to do with fusion, but given the traffic that /. receives, it seems almost irresponsible to let such bullcrap have its way every time it rears its head.

    First off, even from the getgo, ITER is arguably more pointless than it is purposeful. It's nowhere near a stepping stone towards an actual powerplant, even if this sucker proves to be able to do pulsed Q>10 fusion, the technology required for heating won't be economically or thermodynamically feasible for energy production for decades to come. While it's politically a great way to blow a large sum of money (we pulled out of this program at first, but went back in because Bush needed to kiss France's ass for the Iraq war), the most useful science coming out of it will be materials science in trying to deal with high TC superconductors and blanket materials constantly suffering neutron damage; blanket materials we won't need until a real fusion powerplant comes along (once again, decades). That aside, since its original proposal of sustained thermonuc. fusion has been thrown out in favor of hour-long pulses, probably 90% of the physics it will undergo is either known predictable. (In other words, this is NOT the plasma physics equivalent of the LHC, which is actually necessary to set boundary conditions on many physical models).

    Now that's all a big clusterF* of he-said she-said that political spin gets to amplify 100-fold, but what really gets me is the comparison to NIF. Read the next few sentences very carefully:

    1. NIF requires its tiny fuel pellets to be perfectly symmetrical, encased in a gold hohlraum, and perfectly centered, then shot at by the most powerful laser system ever created in earth.

    2. NIF is a giant weapons research project, funded mostly by the DOD (Department, of, Defense) because we want to play nice and not test full blown warheads, and are instead simulating their fusion reactions in a laboratory (Go google NIF's funding, or enjoy the tid-bit that hohlraum was a classified word less than 30 years ago, the mention of which could get you interrogated by the FBI)

    3. The laser system used to beat the crap out of the carefully assembled perfect heavy-water pellet has less than 1% efficiency. I don't care how big your Q is, the technology to fix THAT problem is way more than decades away.

    4. Finally, a real powerplant, using the current studies NIF is undergoing, would require over ~60 perfectly frozen pellets (purpose is for yield, either of turbine-driving energy or more realistically better warhead modeling) per second fusion rate, lasers with a hundred times better efficiency (putting it at, oh say 10%? hah), and quite a bit of gold, that or another mechanism which they aren't studying.

    The next time someone talks NIF like we're not trying to figure out a better way to irradiate large plots of people or land, please just look at them like the idiots they are.
    I'm sorry fusion power is taking so long, we're working on it, and we're working pretty hard. But hey, and near-infinite supply of power from just centrifuged seawater is worth the wait, right? =P
