[65], In June 2012, Japan utility Chubu Electric Power wrote that they regard thorium as "one of future possible energy resources. Consequently, some radioactive dust was released to the environment. He failed. 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. The THTR-300 was a thorium high-temperature nuclear reactor rated at 300 MW electric (THTR-300) in Hamm-Uentrop, Germany. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium. Meaning; PWR. "This is definitely a race," he added. Now they are more interested because of smog," said Professor Li Zhong, a scientist working on the project. 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. "[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. Producing Thorium pebbles for the High-Temperature Gas-Cooled Reactor (HTGR). The study reported that building a ThorCon TMSR-500 would meet Indonesia's regulations for nuclear energy safety and performance. [81] (see table "IAEA Estimates in tons"). These were similar to the reactor designs that produced material for nuclear weapons. The Westphalia ministry of commerce created a fact finding committee. [72], Some experts and politicians want thorium to be "the pillar of the U.S. nuclear future. [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. 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. 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. 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 … Science writer Richard Martin states that nuclear physicist Alvin Weinberg, who was director at Oak Ridge and primarily responsible for the new reactor, lost his job as director because he championed development of the safer thorium reactors. It is difficult to make a practical nuclear bomb from a thorium reactor's byproducts. [1] [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. "[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. [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." "[14] China also finalized an agreement with a Canadian nuclear technology company to develop improved CANDU reactors using thorium and uranium as a fuel. STL is designing a generation IV high-temperature, gas-cooled, pebble-bed reactor, the HTMR100 (100 MWth high-temperature modular reactor). China expects to put thorium reactors into commercial use by 2030.[46]. [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] [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. Get the most popular abbreviation for Thorium High-temperature Reactor updated in 2020 The pebble bed thorium high-temperature reactor THTR 300 was shut down on September 1, 1989, after > 16 000 h operation time. THTR-300 was only in full service for 423 days. 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. The THTR-300 cost €2.05 billion and was predicted to cost an additional €425 million … The LMFBR had a larger breeding rate ... and won the competition." [3], The electrical generation part of the THTR-300 was finished late due to ever-newer requirements and licensing procedures. Reactor . This irradiation process may be altered slightly by removing protactinium-233. "We have huge reserves of thorium. 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]. 4.30) is a further step in the evolutionary development of high-temperature reactors (HTRs). [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. "[34], CANDU reactors are capable of using thorium,[35][36] and Thorium Power Canada has, in 2013, planned and proposed developing thorium power projects for Chile and Indonesia. [68], In Britain, one organisation promoting or examining research on thorium-based nuclear plants is The Alvin Weinberg Foundation. In their opinion, the decision to stop development of thorium reactors, at least as a backup option, “was an excusable mistake.”[4]. 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. Title: Article - Decommissioning of the Thorium High Temperature Reactor (THTR 300) by G, Dietrich, W Neumann and N. Rohl. "[17][28] Friends of the Earth UK considers research into it as "useful" as a fallback option. 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. The reactor kept experiencing technical difficulties, with fuel elements breaking more often than anticipated. India is the "only country in the world with a detailed, funded, government-approved plan" to focus on thorium-based nuclear power. The economic study for the advanced nuclear reactors of the fourth generation fuelled with thorium, e.g. 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. Abbr. "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 THTR 300 is a project that is jointly sponsored by the Federal Republic of Germany, North Rhine-Westphalia, and Hochtemperatur-Kernkraftwerk GmbH. For this reactor, various design options as regards fuel configurations, such as prismatic bed and pebble bed were considered for thermal hydraulics and temperature dsitrbi utoi n anaylssi. 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. A nuclear reactor consumes certain specific fissile isotopes to produce energy.
