The […] In 2018, the New Brunswick Energy Solutions Corporation announced the participation of Moltex Energy in the nuclear research cluster that will work on research and development on small modular reactor technology. Thorium is three times as abundant as uranium and nearly as abundant as lead and gallium in the Earth's crust. It started operating in 1983, synchronized with the grid in 1985, operated at full power in February 1987 and was shut down September 1, 1989. [45], Currently two reactors are under construction in the Gobi desert, with completion expected in 2020. Many of these early trials were able to use high-enriched uranium (HEU) as the fissile ‘driver’ component, and this would not be considered today. House of Lords member Bryony Worthington is promoting thorium, calling it “the forgotten fuel” that could alter Britain's energy plans. Because of its inherent safety, they expect that similar designs could be set up "within" populated cities, like Mumbai or Delhi. 4.30) is a further step in the evolutionary development of high-temperature reactors (HTRs). [64], P3Tek, an agency of the Indonesia Ministry of Energy and Mineral Resource, has reviewed a thorium molten salt reactor by Thorcon called the TMSR-500. 4.44 a unit. The THTR-300 was a helium-cooled high-temperature reactor with a pebble-bed reactor core consisting of approximately 670,000 spherical fuel compacts each 6 centimetres (2.4 in) in diameter with particles of uranium-235 and thorium-232 fuel embedded in a graphite matrix. From 2013 to 2017, 23 Million Euro were budgeted for lighting, safeguarding and the storage of the pellets in the interim storage facility in Ahaus. [38][39][40], At the 2011 annual conference of the Chinese Academy of Sciences, it was announced that "China has initiated a research and development project in thorium MSR technology. Proponents also cite the low weaponization potential as an advantage of thorium due to how difficult it is to weaponize the specific uranium-233/232 and plutonium-238 isotopes produced by thorium reactors, while critics say that development of breeder reactors in general (including thorium reactors, which are breeders by nature) increases proliferation concerns. Comparing the amount of thorium needed with coal, Nobel laureate, Liquid fluoride thorium reactors are designed to be meltdown proof. The fourth reason for the high energy production is the MSR’s high operating temperature (550-700 degrees Celcius) that yields higher efficiencies of electricity production (Juhasz, et al., 2009, p. 4), (Hargraves & Moir, 2010, p. 311). Producing Thorium pebbles for the High-Temperature Gas-Cooled Reactor (HTGR). This page was last edited on 27 December 2020, at 14:11. [49], According to Dr R K Sinha, chairman of their Atomic Energy Commission, "This will reduce our dependence on fossil fuels, mostly imported, and will be a major contribution to global efforts to combat climate change." Increasingly shunted aside, Weinberg was finally forced out in 1973.[10]. [33] Recognized experts, such as Hans Blix, former head of the International Atomic Energy Agency, calls for expanded support of new nuclear power technology, and states, "the thorium option offers the world not only a new sustainable supply of fuel for nuclear power but also one that makes better use of the fuel's energy content. "[11] Nuclear physicist Victor J. Stenger, for one, first learned of it in 2012: It came as a surprise to me to learn recently that such an alternative has been available to us since World War II, but not pursued because it lacked weapons applications. Over half of its 674,000 pebbles cont… The preceding figures are reserves and as such refer to the amount of thorium in high-concentration deposits inventoried so far and estimated to be extractable at current market prices; millions of times more total exist in Earth's 3×1019 tonne crust, around 120 trillion tons of thorium, and lesser but vast quantities of thorium exist at intermediate concentrations. American Geophysical Union, Fall Meeting 2007, abstract #V33A-1161. For one thing: 'Any bomb dropped on a thorium reactor will result in a catastrophic accident.' 80 incidents were logged in its short lifetime. According to Dr. Shamanin, the blanket was based on a concept of a multi-purpose high-temperature gas-cooled low-power reactor fueled by thorium. The 300 MWe Thorium High Temperature Reactor (THTR)at Hamm-Uentrop in Germany operated with thorium-HEU fuel between 1983 and 1989, when it was shut down due to technical problems. But it was apparent to me that my style, my attitude, and my perception of the future were no longer in tune with the powers within the AEC.[9]. [1] ORNL has developed two FHR-class MSR concepts: the 1,500 megawatt electric advanced high-temperature reactor (AHTR) and the 125 megawatt thermal small modular advanced high-temperature reactor (SmAHTR). [42][43] The World Nuclear Association notes that the China Academy of Sciences in January 2011 announced its R&D program, "claiming to have the world's largest national effort on it, hoping to obtain full intellectual property rights on the technology. By: Diarmuid Foley. The HTMR100 will be cooled with helium gas and operate at … It fed power to Germany's grid for 432 days in the late 1980s, before it was shut down for cost, mechanical and other reasons. [69] However, in 2010, the UK's National Nuclear Laboratory (NNL) concluded that for the short to medium term, "...the thorium fuel cycle does not currently have a role to play," in that it is "technically immature, and would require a significant financial investment and risk without clear benefits," and concluded that the benefits have been "overstated. "[14] China also finalized an agreement with a Canadian nuclear technology company to develop improved CANDU reactors using thorium and uranium as a fuel. A nuclear reactor consumes certain specific fissile isotopes to produce energy. [70], In its January 2012 report to the United States Secretary of Energy, the Blue Ribbon Commission on America's Future notes that a "molten-salt reactor using thorium [has] also been proposed. ... his team built a working reactor .... and he spent the rest of his 18-year tenure trying to make thorium the heart of the nation’s atomic power effort. The fuel supply had already been difficult before this decision, and now it was truly at risk. In 2013 India's 300 MWe AHWR (pressurized heavy water reactor) was slated to be built at an undisclosed location. This … "We have huge reserves of thorium. The liquid fluoride thorium reactor ( LFTR; often pronounced lifter) is a type of molten salt reactor. Some experts note possible specific disadvantages of thorium nuclear power: Research and development of thorium-based nuclear reactors, primarily the Liquid fluoride thorium reactor (LFTR), MSR design, has been or is now being done in the United States, United Kingdom, Germany, Brazil, India, China, France, the Czech Republic, Japan, Russia, Canada, Israel, Denmark and the Netherlands. "[17] According to Martin, "China has made clear its intention to go it alone," adding that China already has a monopoly over most of the world's rare earth minerals. The electric conversion system produced 308 megawatts of electricity. [44], In early 2012, it was reported that China, using components produced by the West and Russia, planned to build two prototype thorium MSRs by 2015, and had budgeted the project at $400 million and requiring 400 workers. Consequently, some radioactive dust was released to the environment. "[67] In 2013, Aker Solutions purchased patents from Nobel Prize winning physicist Carlo Rubbia for the design of a proton accelerator-based thorium nuclear power plant. The reactor construction has not yet begun. [2], The European Council established on 4 June 1974 the Joint Undertaking "Hochtemperatur-Kernkraftwerk GmbH" (HKG). [14]:7, Summarizing some of the potential benefits, Martin offers his general opinion: "Thorium could provide a clean and effectively limitless source of power while allaying all public concern—weapons proliferation, radioactive pollution, toxic waste, and fuel that is both costly and complicated to process. "[73] Senators Harry Reid and Orrin Hatch have supported using $250 million in federal research funds to revive ORNL research. Supervisor: Prof E Mulder, Post-Graduate School of Nuclear Science and Engineering. Currently, the most common types of nuclear reactor fuel are: Some believe thorium is key to developing a new generation of cleaner, safer nuclear power. The THTR-300 was a helium-cooled high-temperature reactor with a pebble-bed reactor core consisting of approximately 670,000 spherical fuel compacts each 6 centimetres (2.4 in) in diameter with particles of uranium-235 and thorium-232 fuel embedded in a graphite matrix. The LMFBR had a larger breeding rate ... and won the competition." Student: SK Gintner. [68], In Britain, one organisation promoting or examining research on thorium-based nuclear plants is The Alvin Weinberg Foundation. Lower Production of Transuranic Elements. On October 10, 1991, the 180-metre (590 ft) high dry cooling tower, which at one time was the highest cooling tower in the world, was explosively dismantled and from October 22, 1993 to April 1995 the remaining fuel was unloaded and transported to the intermediate storage in Ahaus. 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. The MSRE reactor, built at Oak Ridge National Laboratory, operated critical for roughly 15,000 hours from 1965 to 1969. According to the World Nuclear Association, there are seven types of reactors that can be designed to use thorium as a nuclear fuel. There have been several significant demonstrations of the use of thorium-based fuels to generate electricity in several reactor types. STL has designed a thorium refinery for the production of reactor-grade thorium. The reasons were that uranium-fueled reactors were more efficient, the research was proven, and thorium's breeding ratio was thought insufficient to produce enough fuel to support development of a commercial nuclear industry. Suitability: Thorium can be used a nuclear fuel in several types of nuclear reactors that include heavy water reactors, high-temperature gas-cooled reactors, boiling (light) water reactors, pressurised (light) water reactors, fast neutron reactors, molten salt … By 1992, a group of firms planned to proceed with construction of a HTR-500, the successor of the THTR-300, but up-rated to a thermal output of 1250 megawatts and an electrical output of 500 megawatts. https://www.nextbigfuture.com/2019/09/p3tek-recommends-thorcon-molten-salt-nuclear-reactor-for-indonesia.html, In May 2010, researchers from Ben-Gurion University of the Negev in Israel and Brookhaven National Laboratory in New York began to collaborate on the development of thorium reactors,[65] aimed at being self-sustaining, "meaning one that will produce and consume about the same amounts of fuel," which is not possible with uranium in a light water reactor. Liquid Fueled Thorium Reactor 40 Megawatt Pilot Plant Outline TEAC 3. The THTR-300 served as a prototype high-temperature reactor (HTR) to use the TRISO pebble fuel produced by the AVR, an experimental pebble bed operated by VEW. The HTMR100 Reactor is a High Temperature Gas Cooled Modular Reactor. [54][55][56][57] India's first commercial fast breeder reactor—the 500 MWe Prototype Fast Breeder Reactor (PFBR)—is approaching completion at the Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu. Moir, Ralph W. and Teller, Edward. [74][75], Alvin Radkowsky, chief designer of the world's second full-scale atomic electric power plant in Shippingport, Pennsylvania, founded a joint US and Russian project in 1997 to create a thorium-based reactor, considered a "creative breakthrough. [3] In 2009, Congressman Joe Sestak unsuccessfully attempted to secure funding for research and development of a destroyer-sized reactor [reactor of a size to power a destroyer] using thorium-based liquid fuel. In 1968, Nobel laureate and discoverer of plutonium, Glenn Seaborg, publicly announced to the Atomic Energy Commission, of which he was chairman, that the thorium-based reactor had been successfully developed and tested.

The country currently gets under 2% of its electricity from nuclear power, with the rest coming from coal (60%), hydroelectricity (16%), other renewable sources (12%) and natural gas (9%). It was decided to shut down THTR-300. In late June 2012, India announced that their "first commercial fast reactor" was near completion making India the most advanced country in thorium research. "[3], After studying the feasibility of using thorium, nuclear scientists Ralph W. Moir and Edward Teller suggested that thorium nuclear research should be restarted after a three-decade shutdown and that a small prototype plant should be built.[4][5][6]. On September 1, 1989, the THTR-300 was deactivated due to its rising cost; in August 1989, the THTR company almost bankrupted after a long period of shut down due to broken components in the hot gas duct. "In the past, the government was interested in nuclear power because of the energy shortage. The THTR-300 cost €2.05 billion and was predicted to cost an additional €425 million … [50] It expects to produce around 25% of its electricity from nuclear power. The THTR-300 was a helium-cooled high-temperature reactor with a pebble bed core consisting of approximately 670,000 spherical fuel compacts each 6 centimetres (2.4 in) in diameter with particles of uranium-235 and thorium-232 fuel embedded in a graphite matrix. [58] The Centre had sanctioned Rs. Abbr. The VHTR is an evolutionary design of the High Temperature Gas Reactor (HTGR). [81] (see table "IAEA Estimates in tons"). In depth: Resource availability » Thorium MSR is safe Thorium, when being irradiated for use in reactors, makes uranium-232, which emits gamma rays. [17], Moir and Teller agree, noting that the possible advantages of thorium include "utilization of an abundant fuel, inaccessibility of that fuel to terrorists or for diversion to weapons use, together with good economics and safety features … "[4] One of these reactors is the High Temperature Reactor (HTR), which consists of a randomly packed bed of fuel pebbles that are cooled by helium. The THTR-300 was a thorium high-temperature nuclear reactor rated at 300 MW electric (THTR-300) in Hamm-Uentrop, Germany. BHAVINI builds breeder reactors in India. Pressurized Water Reactor EAR. “Thorium reactors are safe” Wrong. Dismantling is not expected to start before 2027. This Reactor can facilitate a variety of different fuels using the same geometry. This article discusses the benefits of a HTMR compared to other types of nuclear reactor. After World War II, uranium-based nuclear reactors were built to produce electricity. However, development of thorium power has significant start-up costs. In particular the thermal conductivity is important, since it leads to a lower fuel pellets temperature. [53] That vision of using thorium in place of uranium was set out in the 1950s by physicist Homi Bhabha. The engineering maturity of pebble bed reactors, supported by experimental facilities, makes the HTMR100 as a Generation IV reactor licensable within the next few years. [4], A report by the Bellona Foundation in 2013 concluded that the economics are quite speculative. [48] Validation of its core reactor physics was underway by late 2017. The THTR-300 cost €2.05 billion and was predicted to cost an additional €425 million through December 2009 in decommissioning and other associated costs. A, Mining thorium is safer and more efficient than mining uranium. The THTR-300 served as a prototype high-temperature reactor (HTR) to use the TRISO pebble fuel produced by the AVR, an experimental pebble bed operated by VEW. Thermal processes using high temperature gas cooled reactors (HTGRs) could be a sustainable and environmentally friendly alternative to the presently used various conventional chemical processes. The reactor itself, at the end of its lifetime, will constitute high level waste: 'With or without reprocessing, these fission products have to be disposed of in a geologic repository.' The pressure vessel that contained the pebbles was prestressed concrete. [80], Another estimate of reasonably assured reserves (RAR) and estimated additional reserves (EAR) of thorium comes from OECD/NEA, Nuclear Energy, "Trends in Nuclear Fuel Cycle", Paris, France (2001). The THTR 300 is a project that is jointly sponsored by the Federal Republic of Germany, North Rhine-Westphalia, and Hochtemperatur-Kernkraftwerk GmbH. The German state of North Rhine Westphalia, Federal Republic of Germany, and Hochtemperatur-Kernkraftwerk GmbH (HKG) financed the THTR-300’s construction. [77] Estimates to complete a reactor were originally set at ten years in 2006 (with a proposed operational date of 2015).[78]. 5,677 crore for building the PFBR and “we will definitely build the reactor within that amount,” Mr. Kumar asserted. The German THTR-300 was a prototype commercial power station using thorium as fertile and highly enriched U-235 as fissile fuel. "[17][28] Friends of the Earth UK considers research into it as "useful" as a fallback option. Estimated Additional Reserves REMOTE. The very-high-temperature reactor (VHTR) (see Fig. Compared to the predominant reactor fuel, uranium dioxide (UO 2), thorium dioxide (ThO 2) has a higher melting point, higher thermal conductivity, and lower coefficient of thermal expansion. of the PFBR to September 2016,[62] but India's commitment to long-term nuclear energy production is underscored by the approval in 2015 of ten new sites for reactors of unspecified types,[63] though procurement of primary fissile material—preferably plutonium—may be problematic due to India's low uranium reserves and capacity for production. The THTR-300's power conversion system was similar to the Fort St. Vrain reactor in the USA, in that the reactor coolant transferred the reactor core's heat to water. As with other inactive reactor facilities, costs are still being incurred. The Westphalia ministry of commerce created a fact finding committee. High temperature gas reactors High temperature gas reactor designs using thorium fuel were proposed by the Oak Ridge National Laboratories in 1947. Martin explains that Weinberg's unwillingness to sacrifice potentially safe nuclear power for the benefit of military uses forced him to retire: Weinberg realized that you could use thorium in an entirely new kind of reactor, one that would have zero risk of meltdown. In 1973, however, the US government settled on uranium technology and largely discontinued thorium-related nuclear research. Because this system used a Rankine cycle, water could occasionally ingress into the helium circuit. [2] According to a 2011 opinion piece by a group of scientists at the Georgia Institute of Technology, considering its overall potential, thorium-based power "can mean a 1000+ year solution or a quality low-carbon bridge to truly sustainable energy sources solving a huge portion of mankind’s negative environmental impact. Thank you for helping build the largest language community on the internet. Reactor Details. For another, in Though named thorium high temperature reactor, mostly U-235 was fissioned. The VHTR is a helium-gas-cooled, graphite-moderated, thermal-neutron-spectrum reactor with a core outlet temperature > 900°C, and a goal of 1000°C, sufficient to support high-temperature processes such as production of hydrogen through … It started generating electricity on April 9, 1985, but did not receive permission from the atomic legal authorizing agency to feed electricity to the grid until November 16, 1985. These were similar to the reactor designs that produced material for nuclear weapons. It operated at full power in February 1987 and was shut down September 1, 1989, after operating for less than 16,000 hours. The thermal output of the core was 750 megawatts; heat was transferred to the helium coolant, which then transported its heat to water, which then was used to generate electricity via a Rankine cycle. A scaled up 300-MW version was then built and operated at Fort St Vrain, CO from 1976 to 1989. There is a higher cost of fuel fabrication and reprocessing than in plants using traditional solid fuel rods. This happened just a couple of days after the Chernobyl disaster. The study reported that building a ThorCon TMSR-500 would meet Indonesia's regulations for nuclear energy safety and performance. As of July 2013 the major equipment of the PFBR had been erected and the loading of "dummy" fuels in peripheral locations was in progress. 1 ways to abbreviate Thorium High-temperature Reactor. [7][8] Weinberg himself recalls this period: [Congressman] Chet Holifield was clearly exasperated with me, and he finally blurted out, "Alvin, if you are concerned about the safety of reactors, then I think it may be time for you to leave nuclear energy." The remaining facility was "safely enclosed". A small modular nuclear reactor to replace coal plants could be on the market within 5 years. Now they are more interested because of smog," said Professor Li Zhong, a scientist working on the project.

Thorium is considered the "most abundant, most readily available, cleanest, and safest energy source on Earth," adds science writer Richard Martin. In addition, the transition to thorium could be done through the incineration of weapons grade plutonium (WPu) or civilian plutonium. [5] From 1985 to 1989, the THTR-300 registered 16410 operation hours and generated 2891000 MWh, according to a full-load working time of 423 days. "[76] In 1992, while a resident professor in Tel Aviv, Israel, he founded the US company, Thorium Power Ltd., near Washington, D.C., to build thorium reactors. Raluca presents the Pebble-Bed Advanced High Temperature Reactor (PB-AHTR), a Fluoride Salt Cooled High Temperature Reactor (FHR) designed by University of California (Berkeley) & ORNL & other universities. There are substantial deposits in several other countries (see table "World thorium reserves"). Learn how and when to remove this template message, European Organization for Nuclear Research, https://www.nextbigfuture.com/2019/09/p3tek-recommends-thorcon-molten-salt-nuclear-reactor-for-indonesia.html, India's three-stage nuclear power programme, "Uses For Uranium-233: What Should Be Kept for Future Needs? [17] Monazite is a good source of REEs (Rare Earth Element), but monazites are currently not economical to produce because the radioactive thorium that is produced as a byproduct would have to be stored indefinitely. Created Date: 11/4/2005 6:20:56 PM [65], In June 2012, Japan utility Chubu Electric Power wrote that they regard thorium as "one of future possible energy resources. Thorium High-temperature Reactor Reactor, Pebble, Thorium. Thereafter, thorium is to be the only fuel. "[66], In late 2012, Norway's privately owned Thor Energy, in collaboration with the government and Westinghouse, announced a four-year trial using thorium in an existing nuclear reactor. [60] As of 2017, the design was in the final stages of validation. Category: Reactor Designs, Technology, Thorium. Six of these have all entered into operational service at some point. As was determined in 1989, dismantling would begin after approximately 30 years in safe enclosure.[4]. India has projected meeting as much as 30% of its electrical demands through thorium by 2050. [47], In February 2014, Bhabha Atomic Research Centre (BARC), in Mumbai, India, presented their latest design for a "next-generation nuclear reactor" that burns thorium as its fuel ore, calling it the Advanced Heavy Water Reactor (AHWR). It is difficult to make a practical nuclear bomb from a thorium reactor's byproducts. The heat source is based on a fuel technology with intrinsic safety characteristics. Electricity generated from the PFBR would be sold to the State Electricity Boards at Rs. The economic study for the advanced nuclear reactors of the fourth generation fuelled with thorium, e.g. However nothing is currently in any stage of development. [12][14] Conferences with experts from as many as 32 countries are held, including one by the European Organization for Nuclear Research (CERN) in 2013, which focuses on thorium as an alternative nuclear technology without requiring production of nuclear waste. "[41] In addition, Dr. Jiang Mianheng, son of China's former leader Jiang Zemin, led a thorium delegation in non-disclosure talks at Oak Ridge National Laboratory, Tennessee, and by late 2013 China had officially partnered with Oak Ridge to aid China in its own development. As Moir and Teller later wrote, "The competition came down to a liquid metal fast breeder reactor (LMFBR) on the uranium-plutonium cycle and a thermal reactor on the thorium-233U cycle, the molten salt breeder reactor. After a couple of weeks the power plant was switched on again, but the former supporters withdrew their backing. On May 4, 1986, just 6 months after it had been connected to the power grid, a fuel pebble became lodged in a fuel feed pipe to the reactor core.
