900°C, and a goal of 1000°C, sufficient to support high-temperature processes such as production of hydrogen through … Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium. Reactor Details. It operated at full power in February 1987 and was shut down September 1, 1989, after operating for less than 16,000 hours. Thorium is considered the "most abundant, most readily available, cleanest, and safest energy source on Earth," adds science writer Richard Martin. [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. The MSRE reactor, built at Oak Ridge National Laboratory, operated critical for roughly 15,000 hours from 1965 to 1969. This happened just a couple of days after the Chernobyl disaster. [14] In 2009 the chairman of the Indian Atomic Energy Commission said that India has a "long-term objective goal of becoming energy-independent based on its vast thorium resources to meet India's economic ambitions."[51][52]. If uranium were an asset, it would be a long-term CD with a penalty for convenient withdrawal. 1 ways to abbreviate Thorium High-temperature Reactor. 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. American Geophysical Union, Fall Meeting 2007, abstract #V33A-1161. They estimated the reactor could function without an operator for 120 days. "[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. The pebble bed thorium high-temperature reactor THTR 300 was shut down on September 1, 1989, after > 16 000 h operation time. Supervisor: Prof E Mulder, Post-Graduate School of Nuclear Science and Engineering. The fuel factory in Hanau was decommissioned for security reasons. 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. 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 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. As with other inactive reactor facilities, costs are still being incurred. Thorium High-temperature Reactor Reactor, Pebble, Thorium. [72], Some experts and politicians want thorium to be "the pillar of the U.S. nuclear future. The THTR 300 is a project that is jointly sponsored by the Federal Republic of Germany, North Rhine-Westphalia, and Hochtemperatur-Kernkraftwerk GmbH. There are substantial deposits in several other countries (see table "World thorium reserves"). Lower Production of Transuranic Elements. After a couple of weeks the power plant was switched on again, but the former supporters withdrew their backing. 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]. Increasingly shunted aside, Weinberg was finally forced out in 1973.[10]. He failed. Listen to the audio pronunciation of Thorium High Temperature Reactor on pronouncekiwi. [4], A report by the Bellona Foundation in 2013 concluded that the economics are quite speculative. "In the past, the government was interested in nuclear power because of the energy shortage. As was determined in 1989, dismantling would begin after approximately 30 years in safe enclosure.[4]. The operators played down the incident, which caused a loss of confidence in the regulatory authorities. [2] Heinz Riesenhuber, Federal Secretary of Research at that time, inaugurated it, and it first went critical on September 13, 1983. There have been several significant demonstrations of the use of thorium-based fuels to generate electricity in several reactor types. [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. 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. 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. 5,677 crore for building the PFBR and “we will definitely build the reactor within that amount,” Mr. Kumar asserted. The […] 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). 3,492 crore, revised to Rs. Related acronyms and abbreviations. That research led to the Peach Bottom, PA 40-MW reactor that pro- duced electricity from 1966 to 1974. High temperature gas reactors High temperature gas reactor designs using thorium fuel were proposed by the Oak Ridge National Laboratories in 1947.

Title: Article - Decommissioning of the Thorium High Temperature Reactor (THTR 300) by G, Dietrich, W Neumann and N. Rohl. In addition, the transition to thorium could be done through the incineration of weapons grade plutonium (WPu) or civilian plutonium. In the hybrid thorium setup, thorium-plutonium pellets power a … LFTRs use the thorium fuel cycle with a fluoride -based, molten, liquid salt for fuel. "Thorium-fuelled Reactor Using Molten Salt Technology", "India's experimental Thorium Fuel Cycle Nuclear Reactor [NDTV Report], Data taken from Uranium 2007: Resources, Production and Demand, Nuclear Energy Agency (2008), NEA#6345 (. The HTR has proven in the past, with several demonstration plants, that it is an inherently safe reactor, capable of removing the decay heat by passive means in case of loss of active cooling accidents. The electric conversion system produced 308 megawatts of electricity. The reactor construction has not yet begun. India has projected meeting as much as 30% of its electrical demands through thorium by 2050. [14]:13 Moir and Teller estimated in 2004 that the cost for their recommended prototype would be "well under $1 billion with operation costs likely on the order of $100 million per year," and as a result a "large-scale nuclear power plan" usable by many countries could be set up within a decade. A, Mining thorium is safer and more efficient than mining uranium. "[15], The World Nuclear Association explains some of the possible benefits[16], The thorium fuel cycle offers enormous energy security benefits in the long-term—due to its potential for being a self-sustaining fuel without the need for fast neutron reactors. "[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. Since all natural thorium can be used as fuel no expensive fuel enrichment is needed. This article discusses the benefits of a HTMR compared to other types of nuclear reactor. House of Lords member Bryony Worthington is promoting thorium, calling it “the forgotten fuel” that could alter Britain's energy plans. [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. Moir, Ralph W. and Teller, Edward. The German THTR-300 was a prototype commercial power station using thorium as fertile and highly enriched U-235 as fissile fuel. [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. [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. The original cost of the project was Rs. Because this system used a Rankine cycle, water could occasionally ingress into the helium circuit. Comparing the amount of thorium needed with coal, Nobel laureate, Liquid fluoride thorium reactors are designed to be meltdown proof. It had to be bailed out by the government with 92 million Mark.[6]. Because of its inherent safety, they expect that similar designs could be set up "within" populated cities, like Mumbai or Delhi. 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. 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. The thorium fuel cycle is a potential way to produce long term nuclear energy with low radio-toxicity waste. Thank you for helping build the largest language community on the internet. [14]:157[23], In March 2014, with their reliance on coal-fired power having become a major cause of their current "smog crisis," they reduced their original goal of creating a working reactor from 25 years down to 10. ... 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. Thorium nuclear reactors are unlikely to produce cheaper energy, but the management of spent fuel is likely to be cheaper than for uranium nuclear reactors.[28]. [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). This irradiation process may be altered slightly by removing protactinium-233. "[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. India is the "only country in the world with a detailed, funded, government-approved plan" to focus on thorium-based nuclear power. [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] In particular the thermal conductivity is important, since it leads to a lower fuel pellets temperature. [61], Delays have since postponed the commissioning [criticality?] Significant and expensive testing, analysis and licensing work is first required, requiring business and government support. World monazite resources are estimated to be about 12 million tons, two-thirds of which are in heavy mineral sands deposits on the south and east coasts of India. Westfälischer Anzeiger 13. 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 engineering maturity of pebble bed reactors, supported by experimental facilities, makes the HTMR100 as a Generation IV reactor licensable within the next few years. The pebble bed thorium high-temperature reactor THTR 300 was shut down on September 1, 1989, after > 16 000 h operation time. 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. [12], Others, including former NASA scientist and thorium expert Kirk Sorensen, agree that "thorium was the alternative path that was not taken … "[13][14]:2 According to Sorensen, during a documentary interview, he states that if the US had not discontinued its research in 1974 it could have "probably achieved energy independence by around 2000. [68], In Britain, one organisation promoting or examining research on thorium-based nuclear plants is The Alvin Weinberg Foundation. The German state of North Rhine Westphalia, Federal Republic of Germany, and Hochtemperatur-Kernkraftwerk GmbH (HKG) financed the THTR-300’s construction. According to Chemical & Engineering News, "most people—including scientists—have hardly heard of the heavy-metal element and know little about it...," noting a comment by a conference attendee that "it's possible to have a Ph.D. in nuclear reactor technology and not know about thorium energy. The THTR-300 cost €2.05 billion and was predicted to cost an additional €425 million … The remaining facility was "safely enclosed". The THTR-300 was a thorium high-temperature nuclear reactor rated at 300 MW electric (THTR-300) in Hamm-Uentrop, Germany. The reactor kept experiencing technical difficulties, with fuel elements breaking more often than anticipated. Though named thorium high temperature reactor, mostly U-235 was fissioned. 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. Created Date: 11/4/2005 6:20:56 PM 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. By: Diarmuid Foley. 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. The irradiation would then make uranium-233 in lieu of uranium-232 for use in nuclear weapons—making thorium into a dual purpose fuel. The pressure vessel that contained the pebbles was prestressed concrete. These were similar to the reactor designs that produced material for nuclear weapons. The HTMR100 Reactor is a High Temperature Gas Cooled Modular Reactor. Estimated Additional Reserves REMOTE. ", "The Energy From Thorium Foundation Thorium", "Liquid Fluoride Thorium Reactors: An old idea in nuclear power gets reexamined", "Edward Teller, Global Warming, and Molten Salt Reactors", "Is Thorium the Biggest Energy Breakthrough Since Fire? [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. Abbr. The THTR 300 is a project that is jointly sponsored by the Federal Republic of Germany, North Rhine-Westphalia, and Hochtemperatur-Kernkraftwerk GmbH. 153–63. 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. The Molten Salt Fast Neutron Reactor (MSFR), which will take in thorium fuel cycle, recycling of actinides, closed Th/U fuel cycle with no U enrichment, with enhanced safety and minimal wastes.

Reactor, Pebble, Thorium. Reactor . THTR-300 (Thorium High-Temperature Reactor) Permanent Shutdown. However, development of thorium power has significant start-up costs. [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. [2], The European Council established on 4 June 1974 the Joint Undertaking "Hochtemperatur-Kernkraftwerk GmbH" (HKG). [1][4], Because the operator did not expect the decision to decommission the facility, the plant was put into "safe enclosure" status, given that this was the only technical solution for fast decommissioning, especially in consideration of the lack of a final storage facility.[4]. The THTR-300 was a thorium high-temperature nuclear reactor rated at 300 MW electric (THTR-300) in Hamm-Uentrop, Germany. [60] As of 2017, the design was in the final stages of validation. Thorium is three times as abundant as uranium and nearly as abundant as lead and gallium in the Earth's crust. A scaled up 300-MW version was then built and operated at Fort St Vrain, CO from 1976 to 1989. Over half of its 674,000 pebbles cont… [3], The electrical generation part of the THTR-300 was finished late due to ever-newer requirements and licensing procedures. 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 … Category: Reactor Designs, Technology, Thorium. 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 … Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium. Reactor Details. It operated at full power in February 1987 and was shut down September 1, 1989, after operating for less than 16,000 hours. Thorium is considered the "most abundant, most readily available, cleanest, and safest energy source on Earth," adds science writer Richard Martin. [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. The MSRE reactor, built at Oak Ridge National Laboratory, operated critical for roughly 15,000 hours from 1965 to 1969. This happened just a couple of days after the Chernobyl disaster. [14] In 2009 the chairman of the Indian Atomic Energy Commission said that India has a "long-term objective goal of becoming energy-independent based on its vast thorium resources to meet India's economic ambitions."[51][52]. If uranium were an asset, it would be a long-term CD with a penalty for convenient withdrawal. 1 ways to abbreviate Thorium High-temperature Reactor. 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. American Geophysical Union, Fall Meeting 2007, abstract #V33A-1161. They estimated the reactor could function without an operator for 120 days. "[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. The pebble bed thorium high-temperature reactor THTR 300 was shut down on September 1, 1989, after > 16 000 h operation time. Supervisor: Prof E Mulder, Post-Graduate School of Nuclear Science and Engineering. The fuel factory in Hanau was decommissioned for security reasons. 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. 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 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. As with other inactive reactor facilities, costs are still being incurred. Thorium High-temperature Reactor Reactor, Pebble, Thorium. [72], Some experts and politicians want thorium to be "the pillar of the U.S. nuclear future. The THTR 300 is a project that is jointly sponsored by the Federal Republic of Germany, North Rhine-Westphalia, and Hochtemperatur-Kernkraftwerk GmbH. There are substantial deposits in several other countries (see table "World thorium reserves"). Lower Production of Transuranic Elements. After a couple of weeks the power plant was switched on again, but the former supporters withdrew their backing. 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]. Increasingly shunted aside, Weinberg was finally forced out in 1973.[10]. He failed. Listen to the audio pronunciation of Thorium High Temperature Reactor on pronouncekiwi. [4], A report by the Bellona Foundation in 2013 concluded that the economics are quite speculative. "In the past, the government was interested in nuclear power because of the energy shortage. As was determined in 1989, dismantling would begin after approximately 30 years in safe enclosure.[4]. The operators played down the incident, which caused a loss of confidence in the regulatory authorities. [2] Heinz Riesenhuber, Federal Secretary of Research at that time, inaugurated it, and it first went critical on September 13, 1983. There have been several significant demonstrations of the use of thorium-based fuels to generate electricity in several reactor types. [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. 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. 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. 5,677 crore for building the PFBR and “we will definitely build the reactor within that amount,” Mr. Kumar asserted. The […] 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). 3,492 crore, revised to Rs. Related acronyms and abbreviations. That research led to the Peach Bottom, PA 40-MW reactor that pro- duced electricity from 1966 to 1974. High temperature gas reactors High temperature gas reactor designs using thorium fuel were proposed by the Oak Ridge National Laboratories in 1947.

Title: Article - Decommissioning of the Thorium High Temperature Reactor (THTR 300) by G, Dietrich, W Neumann and N. Rohl. In addition, the transition to thorium could be done through the incineration of weapons grade plutonium (WPu) or civilian plutonium. In the hybrid thorium setup, thorium-plutonium pellets power a … LFTRs use the thorium fuel cycle with a fluoride -based, molten, liquid salt for fuel. "Thorium-fuelled Reactor Using Molten Salt Technology", "India's experimental Thorium Fuel Cycle Nuclear Reactor [NDTV Report], Data taken from Uranium 2007: Resources, Production and Demand, Nuclear Energy Agency (2008), NEA#6345 (. The HTR has proven in the past, with several demonstration plants, that it is an inherently safe reactor, capable of removing the decay heat by passive means in case of loss of active cooling accidents. The electric conversion system produced 308 megawatts of electricity. The reactor construction has not yet begun. India has projected meeting as much as 30% of its electrical demands through thorium by 2050. [14]:13 Moir and Teller estimated in 2004 that the cost for their recommended prototype would be "well under $1 billion with operation costs likely on the order of $100 million per year," and as a result a "large-scale nuclear power plan" usable by many countries could be set up within a decade. A, Mining thorium is safer and more efficient than mining uranium. "[15], The World Nuclear Association explains some of the possible benefits[16], The thorium fuel cycle offers enormous energy security benefits in the long-term—due to its potential for being a self-sustaining fuel without the need for fast neutron reactors. "[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. Since all natural thorium can be used as fuel no expensive fuel enrichment is needed. This article discusses the benefits of a HTMR compared to other types of nuclear reactor. House of Lords member Bryony Worthington is promoting thorium, calling it “the forgotten fuel” that could alter Britain's energy plans. [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. Moir, Ralph W. and Teller, Edward. The German THTR-300 was a prototype commercial power station using thorium as fertile and highly enriched U-235 as fissile fuel. [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. [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. The original cost of the project was Rs. Because this system used a Rankine cycle, water could occasionally ingress into the helium circuit. Comparing the amount of thorium needed with coal, Nobel laureate, Liquid fluoride thorium reactors are designed to be meltdown proof. It had to be bailed out by the government with 92 million Mark.[6]. Because of its inherent safety, they expect that similar designs could be set up "within" populated cities, like Mumbai or Delhi. 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. 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. The thorium fuel cycle is a potential way to produce long term nuclear energy with low radio-toxicity waste. Thank you for helping build the largest language community on the internet. [14]:157[23], In March 2014, with their reliance on coal-fired power having become a major cause of their current "smog crisis," they reduced their original goal of creating a working reactor from 25 years down to 10. ... 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. Thorium nuclear reactors are unlikely to produce cheaper energy, but the management of spent fuel is likely to be cheaper than for uranium nuclear reactors.[28]. [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). This irradiation process may be altered slightly by removing protactinium-233. "[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. India is the "only country in the world with a detailed, funded, government-approved plan" to focus on thorium-based nuclear power. [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] In particular the thermal conductivity is important, since it leads to a lower fuel pellets temperature. [61], Delays have since postponed the commissioning [criticality?] Significant and expensive testing, analysis and licensing work is first required, requiring business and government support. World monazite resources are estimated to be about 12 million tons, two-thirds of which are in heavy mineral sands deposits on the south and east coasts of India. Westfälischer Anzeiger 13. 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 engineering maturity of pebble bed reactors, supported by experimental facilities, makes the HTMR100 as a Generation IV reactor licensable within the next few years. The pebble bed thorium high-temperature reactor THTR 300 was shut down on September 1, 1989, after > 16 000 h operation time. 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. [12], Others, including former NASA scientist and thorium expert Kirk Sorensen, agree that "thorium was the alternative path that was not taken … "[13][14]:2 According to Sorensen, during a documentary interview, he states that if the US had not discontinued its research in 1974 it could have "probably achieved energy independence by around 2000. [68], In Britain, one organisation promoting or examining research on thorium-based nuclear plants is The Alvin Weinberg Foundation. The German state of North Rhine Westphalia, Federal Republic of Germany, and Hochtemperatur-Kernkraftwerk GmbH (HKG) financed the THTR-300’s construction. According to Chemical & Engineering News, "most people—including scientists—have hardly heard of the heavy-metal element and know little about it...," noting a comment by a conference attendee that "it's possible to have a Ph.D. in nuclear reactor technology and not know about thorium energy. The THTR-300 cost €2.05 billion and was predicted to cost an additional €425 million … The remaining facility was "safely enclosed". The THTR-300 was a thorium high-temperature nuclear reactor rated at 300 MW electric (THTR-300) in Hamm-Uentrop, Germany. The reactor kept experiencing technical difficulties, with fuel elements breaking more often than anticipated. Though named thorium high temperature reactor, mostly U-235 was fissioned. 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. Created Date: 11/4/2005 6:20:56 PM 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. By: Diarmuid Foley. 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. The irradiation would then make uranium-233 in lieu of uranium-232 for use in nuclear weapons—making thorium into a dual purpose fuel. The pressure vessel that contained the pebbles was prestressed concrete. These were similar to the reactor designs that produced material for nuclear weapons. The HTMR100 Reactor is a High Temperature Gas Cooled Modular Reactor. Estimated Additional Reserves REMOTE. ", "The Energy From Thorium Foundation Thorium", "Liquid Fluoride Thorium Reactors: An old idea in nuclear power gets reexamined", "Edward Teller, Global Warming, and Molten Salt Reactors", "Is Thorium the Biggest Energy Breakthrough Since Fire? [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. Abbr. The THTR 300 is a project that is jointly sponsored by the Federal Republic of Germany, North Rhine-Westphalia, and Hochtemperatur-Kernkraftwerk GmbH. 153–63. 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. The Molten Salt Fast Neutron Reactor (MSFR), which will take in thorium fuel cycle, recycling of actinides, closed Th/U fuel cycle with no U enrichment, with enhanced safety and minimal wastes.
