That means it won't give off transuranic atoms like plutonium, americum, and other nasty byproducts of nuclear energy that find themselves in waste. Because we can’t use thorium to make bombs, we have ignored thorium since the 1940s. He's available for consulting engagements, speaking engagements and Board positions. There are not “thorium reactors,” but rather proposals to use thorium as a “fuel” in different types of reactors, including existing light-water reactors and various fast breeder reactor designs. Another myth is that thorium reactors can run at atmospheric temperatures, in order to produce power they must be run differently and would not be at atmospheric temperatures. Fact sheet completed in January 2009 And this--in large part was because the Thorium reactor operated low pressures whereas, water-cooled reactors operated the high … Reactors are big. This leads to technical complications. Thorium reactors generate significantly less radioactive waste, and can re-use separated uranium, making the reactor self-sufficient once started. “the most realistic timeframe for fusion in actual utility-scale generation is 2050 at the earliest (and more likely much later), and there are exactly zero thorium nuclear plants operating in the world. With some modifications, today’s commercial nuclear reactors could switch to thorium-based fuels, but at great cost. There are not “thorium reactors,” but rather proposals to use thorium as a “fuel” in different types of reactors, including existing light-water reactors and various fast breeder reactor designs. This was covered as part of the And then there’s the bad section of CleanTechnica‘s review of his climate action plan (tl;dr: good on carbon tax, meh on other things, really bad on energy). Save up to 70% off the cover price when you subscribe to Discover magazine. A 2015 independent review of the LFTR concept by the Electric Power Research Institute deemed it a “potentially transformational technology for meeting future energy … A Forgotten Legacy: How Nuclear Reactors Built for War Transformed Peacetime Science, The Fear of Setting the Planet on Fire with a Nuclear Weapon, Miss Out on Earth Day? Highly enriched uranium and separated plutonium are nuclear weapons materials. Molten salt nuclear reactors. Opinions and comments published on this site may not be sanctioned by and do not necessarily represent the views of CleanTechnica, its owners, sponsors, affiliates, or subsidiaries. Seven years ago, CleanTechnica published its policy position to not cover thorium nuclear reactors. Don’t Worry — Here Are Ways to Help the Environment All Year, Residents Rallied to Measure Radiation After Fukushima. With or without reprocessing, these fission products have to be disposed of in a geologic repository. At the time, the evidence was just as clear. We, the government, won’t support it. You’ll note what the cheapest forms of generation are in 2018: utility-scale wind and solar. Your website access code is located in the upper right corner of the Table of Contents page of your digital edition. Therefore, fabricating fuel with U-233 is very So the proliferation problem remains — either bomb-usable uranium-233 or bomb-useable plutonium is created and can be separated out by reprocessing. This is because the liquid fluoride thorium reactors did not produce as much plutonium, needed for developing nuclear weapons, as uranium-powered reactors. Toshiba Westinghouse is bankrupt and was bought by Brookfield for the 40 to 80 years of decommissioning service revenue, not to build new reactors. The low modern cost of wind and solar along with the low cost of natural gas generation and the inherent challenges of nuclear has seen a bunch of reactors shut down and fleet reduction announcements globally. As the World Nuclear Association documents, nuclear started its decline in 2006, long before Fukushima. ... Construction work resumes on … Drops Green Hydrogen Bomb On Fossil Energy — Just For Starters, More Green Hydrogen In US / Netherlands Offshore Wind Hookup, 200 Years Later, Silver-Zinc Energy Storage Is Having Its Moment. He is editor of The Future is Electric and designing for health. This list is an important piece of information on thorium use, hence merits an independent article. Some of the largest reserves are found in Idaho in the U.S. Importantly, because plutonium is not created as a waste product in a thorium reactor, it cannot be separated from the waste and used to make nuclear weapons. Uranium fuel does not make the plumbing any different - remember the Oak Ridge MSRE ran on various fuels. Basically, it seems the “best bet” in terms of reactor design, is something called the Liquid Fluoride Thorium Reactor or LFTR. Reprocessed thorium creates even more risks due to the highly radioactive U-232 created in the reactor. Image courtesy Yang2020 campaign with annotation by author. Not a Proliferation Solution Molten salt reactors (MSRs) are well suited to thorium fuel, and while they were first conceived of in the 1940s, as … Email Ask@DiscoverMagazine.com. This claim is wrong. Additionally, there is the persistent perception that thorium reactors are intrinsically proliferation-resistant. The successful breeder ... His work on the Thorium reactor led him to believe that a significantly higher level of safety was possible. In this case, fissile uranium-233 is also mixed with non-fissile uranium-238. So why did CleanTechnica stop bothering with this in 2012? They are all opportunity costs.”. In addition, as noted, inhalation of thorium-232 produces a higher dose than the same amount of uranium-238 (either by radioactivity or by weight). Of course, they’re still not perfect. Sign up for our free daily newsletter or weekly newsletter to never miss a story. More neutrons are released per neutronabsorbed in the fuel in a traditional (thermal) type of reactor expensive and difficult. Thorium is not actually a “fuel” because it is not fissile and therefore cannot be used to start or sustain a nuclear chain reaction. FALSE Like all reactors, Thorium reactors need some fissile material to start up. He is an active advocate for developing liquid fluoride thorium reactor (LFTR) technology, the details of which were covered in our earlier podcast: A Detailed Exploration of Thorium's Potential As An Energy Source.That interview concluded with Kirk's … Even though a conventional meltdown would be unlikely, thorium still produces harmful radiation that needs to be contained, and something could always go wrong. It is true that such enrichment would not be a straightforward matter because the U-233 is contaminated with U-232, which is highly radioactive and has very radioactive radionuclides in its decay chain. While the mix of fission products is somewhat different than with uranium fuel, the same range of fission products is created. But the chart above highlights the precipitous drop in the price of both wind and solar technologies. Updated July 2009. Have a tip for CleanTechnica, want to advertise, or want to suggest a guest for our CleanTech Talk podcast? Thorium also is somewhat unique in that in can be dissolved in molten salt to form a liquid core, a design that has many unique reprocessing and safety features. Nonetheless, the first thorium-based nuclear reactor was built at the Indian Point Energy Center, New York, in 1962. Audi Talks Range On Twitter, & Gets Into Some Trouble, Honda Fumbles The Ball With The 2022 Acura MDX. News is published on CleanTechnica.com, while reports are published on Future-Trends.CleanTechnica.com/Reports/ and buying guides are here. Proposal to split of sub-section: List of thorium-fueled reactors. Thus private industry won’t invest in it.” ... or LFTR.Courtesy Flibe Energy resembles the LFTR in Sorensen’s own spin on Weinberg’s thorium breeder reactor work from the 1960s. They’ll have to fight for commercial share in a space where they are very much the unknown, unproven, risky alternative against very well known, widely deployed, effective and cheap competitors. Thorium nuclear power might well be the answer for some countries, though; India and China are investing heavily in its development. There were some criticisms of this fact sheet at the time, and CleanTechnica published them too. None of these has a chance to help solve the problem, which we need implemented now. Nine Years Later, Many Scientists Still Ignore Their Data, How the U.S. Could Have an All-Renewable Energy Grid, Energy Scavengers: Static Electricity Could Power the World. There’s no reason to think that Gen IV reactors, whenever they actually get to a stage where they might be deployed commercially, will end up being cheaper than alternatives. The Russkies built three on the Volga and ran them for 40 years but we didn't. How do we know? Let’s start with the candidate, Andrew Yang. Those renewable technologies have all of the advantages of nuclear — very low carbon emissions per MWh, very low pollution per MWh, low direct or secondary mortality impacts per MWh — a bunch of additional advantages — cheaper, faster, viable in all countries — with none of the disadvantages of nuclear — nuclear waste, terrorism concerns, inflexibility, low social license. U-232, which has a half-life of about 70 years, is extremely radioactive and is therefore very dangerous in small quantities: a single small particle in a lung would exceed legal radiation standards for the general public. This will make the spent fuel quite radiotoxic, in addition to all the fission products in it. In this way, thorium reactors not only generate less waste than conventional reactors, but also help to rectify the nuclear waste disposal problem. What did CleanTechnica say about thorium and other next-generation nuclear in our review of his plan? It takes 90% enrichment to make weapons-usable uranium, but very little additional work is needed to move from 20% enrichment to 90% enrichment. They may be boring and low-tech, but they are cheap, fast to build, reliable, predictable, and have incredibly low negative externalities. Read our privacy policy. It has been claimed that thorium fuel cycles with reprocessing would be much less of a proliferation risk because the thorium can be mixed with uranium-238. The radiation-dose-related problems associated with separating U-233 from U-238 and then handling the U-233 would be considerable and more complex than enriching natural uranium for the purpose of bomb making. Noel Wauchope says: don't believe the hype.. Thorium reactors are the latest flavour in nuclear power hype. He regularly publishes analyses of low-carbon technology and policy in sites including Newsweek, Slate, Forbes, Huffington Post, Quartz, CleanTechnica and RenewEconomy, and his work is regularly included in textbooks. So why didn't we use thorium reactors more? The primary U.S. company advocating for thorium fuel is Thorium Power (www.thoriumpower.com). And that isn’t commercially unproven technologies, that’s technology which has been being commissioned for 50 years. The subsection "List of thorium-fueled reactors" is proposed to be split to a new article List of thorium-fueled reactors for the following reasons: . Solid State Batteries -- They're Everywhere! Most of the separative work is needed to go from natural uranium, which has 0.7% uranium-235, to 20% U-235. ... but very little additional work is needed to move from 20% enrichment to 90% enrichment. Of course, I’ve looked at the likelihood of next-generation nuclear, including the molten-salt reactors necessary for thorium nuclear generation, in depth as well. According to their enthusiastic proponents, these reactors will be “smaller, safer, cheaper, cleaner”, will take over the energy market in great numbers, and...will reinvent the global energy landscape and sketch an end to our dependence … Importantly, because plutonium is not created as a waste product in a thorium reactor, it cannot be separated from the waste and used to make nuclear weapons. It should also be noted that inhalation of a unit of radioactivity of thorium-232 or thorium-228 (which is also present as a decay product of thorium-232) produces a far higher dose, especially to certain organs, than the inhalation of uranium containing the same amount of radioactivity. The International Nuclear Agency predicts that the thorium cycle won’t be commercially viable while uranium is still readily available. We have solutions today. He then goes on to offer an alternative to the prevailing view. I’m trying to think of something equivalently slow-paced in the world of modern generation technology that isn’t fusion generation and mostly failing. ... it's an important design criterium. There are also often hazardous non-radioactive metals in both thorium and uranium mill tailings. France has invested € 1 million investigating corrosion problems found when a test reactor in the U.S. was shut down in 1969 after four years of operation. So in 2002, six technologies were chosen and it’s possible that a couple of them might be generating electricity commercially sometime after 2040. Unlike almost every other technology we’ve invented, it just gets more expensive. If the spent fuel is not reprocessed, thorium-232 is very-long lived (half-life:14 billion years) and its decay products will build up over time in the spent fuel. Most of the separative work is needed to go from natural uranium, which has 0.7% uranium-235, to 20% U-235. In this reactor, because thorium is not a fissile material, you actually need either plutonium or enriched uranium to start it. Assuming you've successfully miniaturised and sealed the reactor to make a lightweight, small, plug and play unit that can be replaced in its entirety should it have a problem. Thorium isn't fissile on its own, but it can absorb a neutron and decay to U-233 (which is fissile). But seven years later, there’s still no commercial product, no commercial siting approved, no regulatory approval, and in fact not much of any movement. Research and development of thorium fuel has been undertaken in Germany, India, Japan, Russia, the UK, and the U.S. for more than half a century. Thorium reactors, some say, can pro... Today we're going to take a second look at a technology that, in the past few years, has become something of a cult icon. The fission of thorium creates long-lived fission products like technetium-99 (half-life over 200,000 years). […]. Consider becoming a CleanTechnica member, supporter, or ambassador — or a patron on Patreon. Thorium is not actually a “fuel” because it is not fissile and therefore cannot be used to start or sustain a nuclear chain reaction. Why aren’t we using thorium in nuclear reactors, given the possibility of a meltdown is nearly zero and the waste cannot be used to make bombs? That’s the same reason SNC Lavalin bought CANDU. With water cooled reactors, obviously having moisture ingress won't lead to any … Every component that comes into contact with the brew will have to be made of a specialized, high-tech alloy that can resist them. By the time any of these technologies actually see the market, they’ll be like the Christian concept of a god in a world of science, with nowhere to stand and nothing to do. We could have been using MHD coal generators but you can't make bombs with those. In most proposed thorium fuel cycles, reprocessing is required to separate out the U-233 for use in fresh fuel. The radioactivity associated with these is expected to be considerably less than that associated with a comparable amount of uranium milling. Molten salt reactors offer potential improvements in reactor safety. This is misleading. What Does That Mean? Thorium fuel cycles without reprocessing would offer the same temptation to reprocess as today’s once-through uranium fuel cycles. reprocess nuclear fuel, you won't be able to realize the benefits of the breeder reactor. In this way, thorium reactors not only generate less waste than conventional reactors, but also help to rectify the nuclear waste disposal problem. (adsbygoogle = window.adsbygoogle || []).push({}); Appreciate CleanTechnica’s originality? You’ll note what isn’t cheapest: nuclear. What about the Gen IV International Forum? For instance, the bone surface dose from breathing an amount (mass) of insoluble thorium is about 200 times that of breathing the same mass of uranium. Compared to uranium, the thorium fuel cycle is likely to be even more costly. Most of the reactors in Japan that were shut down won’t be coming back on line. But in principle, the separation can be done, especially if worker safety is not a primary concern; the resulting U-233 can be used to make bombs. The nuclear industry in the US is lobbying for subsidies and tax breaks to allow existing reactors to stay open, mostly without success. Could thorium be the faltering nuclear industry’s salvation -- or is it a mirage? The International Nuclear Agency predicts that the thorium cycle won’t be commercially … Ongoing Technical Problems Hinkley in the UK is a Gen III reactor design and continues to be pushed forward by the conservative government there despite a price tag of 15 cents USD per kWh guaranteed for 35 years. There’s little reason to consider thorium, molten salt reactors and Gates’ “traveling wave” TerraPower technology when considering the future of energy. By Arjun Makhijani and Michele Boyd Most of the problems currently associated with today's solid-uranium-fuelled reactors simply do not apply to LFTRs powered by thorium. Similarly, other Gen III reactors in France and Finland are years and billions over budget. Even though a conventional meltdown would be unlikely, thorium still produces harmful radiation that needs to be contained, and something could always go wrong. This has proven true for airborne wind energy and many other technologies I’ve assessed, including next-generation nuclear. One reason reprocessing thorium fuel cycles haven’t been successful is that uranium-232 (U-232) is created along with uranium-233. The content produced by this site is for entertainment purposes only. In fact, India has been trying to develop a thorium breeder fuel cycle for decades but has not yet done so commercially. The proposed thorium reactor has other advantages as well. Thorium salt reactors are small, for reactors. In this scenario thorium would be the base fuel in a so-called "breeder reactor." They're Everywhere! That last safety advantage is also the main drawback of thorium. Why is that? The advocates of Thorium reactors have some notable proponents including Carlo Rubbia at CERN (European Organization for Nuclear Research) and Kirk Sorensen, a former NASA rocket engineer and now chief nuclear technologist at Teledyne Brown Engineering. As I said to a commenter elsewhere recently, I have a simple rule of thumb for assessing technologies (in addition to my often exceeding deep ways of assessing them): If a technology has been in existence for decades and yet there are no commercial installations of it anywhere in the world, there is very little likelihood of it becoming viable. Thorium may be abundant and possess certain technical advantages, but it does not mean that it is economical. In addition, U-233 is as effective as plutonium-239 for making nuclear bombs. Third-party articles on his analyses and interviews have been published in dozens of news sites globally and have reached #1 on Reddit Science. But the real reason we use uranium over thorium is a result of wartime politics. The history of building nuclear that we know how to build today indicates a 10–15 year timeframe for the known technology. Liquid fluoride thorium reactor was nominated as a Engineering and ... there's already the thorium fuel cycle article discussing many of the thorium reactor issues; this also needs work. Two years ago, we interviewed Kirk Sorensen about the potential for thorium to offer humanity a safe, cheap and abundant source of energy. The opposite is likely to be true, that they will be much more expensive than the alternatives and with other unappealing characteristics. by Michael Barnard. However, thorium comes with its own challenges. That doesn't mean they're small, it's just a relative term. This is because U-233 is five atomic weight units lighter than U-238, compared to only three for U-235. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.According to proponents, a thorium fuel cycle offers several potential advantages over a uranium fuel cycle—including much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced nuclear waste production. Demonstrated sometime within ten years. The claim is that if the uranium-238 content is high enough, the mixture cannot be used to make bombs without a complex uranium enrichment plant. Besides remote fuel fabrication and issues at the front end of the fuel cycle, thorium-U-233 breeder reactors produce fuel (“breed”) much more slowly than uranium-plutonium-239 breeders. Jason talks about the very promising liquid fluoride molten salt thorium reactor (LFTR) and why it won't be developed in the US. Published on October 30th, 2019 | However, mine wastes will pose long-term hazards, as in the case of uranium mining. A fissile material, such as uranium-235 (U-235) or plutonium-239 (which is made in reactors from uranium-238), is required to kick-start the reaction. Nuclear doesn’t get cheaper. […] At least four of the systems have significant operating experience already in most respects of their design, which provides a good basis for further R&D and is likely to mean that they can be in commercial operation before 2030.”. A Fact Sheet Produced by the Institute for Energy and Environmental Research and Physicians for Social Responsibility. It’s worth looking at the unsubsidized LCOE for different forms of generation, per Lazard. Further, while an enrichment plant is needed to separate U-233 from U-238, it would take less separative work to do so than enriching natural uranium. He works with startups, existing businesses and investors to identify opportunities for significant bottom line growth and cost takeout in our rapidly transforming world. Using thorium in a nuclear reactor creates radioactive waste that proponents claim would only have to be isolated from the environment for 500 years, as opposed to the irradiated uranium-only fuel that remains dangerous for hundreds of thousands of years. There was a blip of increase due to China finally getting some of its reactors going, but that’s ended as China has delayed most new starts while simultaneously increasing wind and solar. Thorium, which refers to thorium-232, is a radioactive metal that is about three times more abundant than uranium in the natural environment. Cold War-era governments (including ours) backed uranium-based reactors because they produced plutonium — handy for making nuclear weapons. Get unlimited access when you subscribe. By the time any get to commercial market availability, the cost of renewables will have only fallen further, making any nuclear even less competitive. Not a Waste Solution Uranium sector won’t catch a break. Thorium cycles exclusively allow thermal breeder reactors (asopposed to fast breeders). India is sometimes cited as the country that has successfully developed thorium fuel. Want it all? Getting there won’t be easy — not least because hot molten salts can be just as corrosive as they sound. Today, the United States has a Democratic presidential candidate in the top 10 who loves thorium, yet CleanTechnica still ignores it. Advertise with CleanTechnica to get your company in front of millions of monthly readers. Thorium itself is a neutron poison and needs to be irradiated by neutrons (coming from somewhere) in order to start making good nuclear fuel. This means that, like uranium fuel with reprocessing, bomb-making material is separated out, making it vulnerable to theft or diversion. The fact sheet was as follows. Your email address is used to log in and will not be shared or sold. […], The thorium crowd likes to point at India and China, but China has committed to only build a couple of molten salt reactors with a 12 MW capacity that might use thorium at some future date, and India has even less ambitious plans. Most importantly, meltdowns aren’t possible with thorium reactors because the reaction is not self-sustaining. The uranium 233 produced in thorium reactors is contaminated with uranium 232, which is produced through several different neutron absorption pathways. Japan thinks it can make a thorium prototype reactor for $300 million. As a result, CleanTechnica‘s policy will be to continue to ignore them in favor of the actually transformative technologies reshaping our world for the better. None are likely to be in commercial operation before 2040 at the earliest. That’s 38+ years to commercialization of a technology. Well, the breakdown products just won't make bombs. The plant requires relatively low input energy, from 60 MWt, which can make them up to 50 percent more efficient than other reactors. Yes, the Andrew Yang campaign is promising next generation reactors on the grid in eight years. Not an Economic Solution Physicists Detect the "Spooky Popcorn of the Universe", Page-Turning Science Books: The First Female Physicians, Breaking Drug Taboos, and a Look Inside Crime Labs. The reprocessing cycle does not resolve the proliferation risk. — Dennis Dorando, Concord, Calif. It’s certainly possible to base nuclear reactors around thorium, as opposed to the most commonly used element, uranium. But the real reason we use uranium over thorium is a result of wartime politics. Have a question for Ask Discover? There is just no way to avoid proliferation problems associated with thorium fuel cycles that involve reprocessing. And given that the average nuclear plant takes 15 years for a commercial deployment, and that’s for known, established technologies, it could easily be 2045 by the time Gen IV reactors are pumping electricity into the grid commercially. Maybe in 2002 the thought of competitive nuclear generation was reasonable. Tags: Andrew Yang, Election 2020, Molten Salt Reactors, Stephen Hawkings, thorium, united states. The New, All New, Really New Toyota Mirai -- It's NEW! Thorium “fuel” has been proposed as an alternative to uranium fuel in nuclear reactors. Some proposed thorium fuel cycles even require 20% enriched uranium in order to get the chain reaction started in existing reactors using thorium fuel. Michael Barnard is Chief Strategist with TFIE Strategy Inc and co-founder of two current startups. Thorium cannot in itself power a reactor; unlike natural uranium, it does not contain enough fissile material to initiate a nuclear chain reaction. If you are a Zinio, Nook, Kindle, Apple, or Google Play subscriber, you can enter your website access code to gain subscriber access. We got hooked on uranium and plutonium. Large known deposits are in Australia, India, and Norway. ... And there were reactors fueled with thorium, a fertile element that sits two slots to the left of uranium in the periodic table, and is about three times more abundant in the Earth’s … That’s the reality of nuclear technology advances. Proponents claim that thorium fuel significantly reduces the volume, weight, and long-term radiotoxicity of spent fuel. Contact us here. Of course, they’re still not perfect. Maybe commercial deployment beginning in 12 years. Sign up for our email newsletter for the latest science news. As Mark Z. Jacobson said in our email conversation, […]: “I think the more wasteful parts of his proposal are spending on thorium, nuclear fusion, and geoengineering. There is no empirical evidence suggesting that a 2027 time frame is remotely likely, and Top 100 Climate Influencing academics think it’s wasteful and not helpful. U-232 also has highly radioactive decay products. France is on track to reduce its nuclear capacity. And thorium reactors likely would be somewhat safer because of thorium-based fuel’s greater stability versus uranium-based fuel, with the added benefit of not producing as much nuclear bomb fuel. The use of enriched uranium or plutonium in thorium fuel has proliferation implications. That, buy the way, is why we discarded clean coal technology in 1953. More uranium-238 does dilute the uranium-233, but it also results in the production of more plutonium-239 as the reactor operates. “Some of these reactor designs could be demonstrated within the next decade, with commercial deployment beginning in 2030.”. That’s an even less enthralling statement. CleanTechnica is the #1 cleantech-focused news & analysis website in the US & the world, focusing primarily on electric cars, solar energy, wind energy, & energy storage. The Curve Appears to Be Flattening on CO2 Emissions. This makes worker protection more difficult and expensive for a given level of annual dose. Finally, the use of thorium also creates waste at the front end of the fuel cycle. “After some two years’ deliberation and review of about one hundred concepts, late in 2002 GIF (then representing ten countries) announced the selection of six reactor technologies which they believe represent the future shape of nuclear energy. The enriched uranium fuel or plutonium fuel also maintains the chain reaction until enough of the thorium target material has been converted into fissile uranium-233 (U-233) to take over much or most of the job. — Here are Ways to Help the Environment all Year, Residents Rallied Measure.
