Why resurge in interest ? Scientists at the Nuclear Research and Consultancy Group (NRG) in Petten, Netherlands, have commenced the world’s first thorium molten salt reactor (TMSR) experiment in more than 45 years Molten salt reactors and accelerator driven reactors are still conceptual, though the other five have all been operational at some point. Scientists at the Nuclear Research and Consultancy Group (NRG) in Petten, Netherlands, have begun the world’s first thorium molten salt reactor experiment in over 45 years. The first experiment is on a setup called a molten-salt fast reactor, which burns thorium salt and in theory should also be able to consume spent nuclear fuel from typical uranium fission reactions. More About Thorium. Additionally, there is the persistent perception that thorium reactors are intrinsically proliferation-resistant. One reactor will be built to study uranium molten salt fuel, a second reactor will be built to study thorium molten salt fuel, and a third reactor will be built to study the use of traditional nuclear waste as a fuel to produce energy. The pro-thorium lobby claim a single tonne of thorium burned in a molten salt reactor (MSR) – typically a liquid fluoride thorium reactor (LFTR) – which has liquid rather than solid fuel, can Molten salt reactors offer potential improvements in reactor safety. Nearly a decade later, Irish is the CEO of New York City-based Terrestrial Energy, a company that expects to have a molten-salt reactor online before 2030. MARTIN: Yes, so the molten salt reactor experiment ran from about '59 until 1973, when it was canceled, and the director of Oak Ridge, Alvin Weinberg, who was a great proponent of thorium and of 1. It’s designed to protect itself against meltdown, and it’s also not as easy to weaponize A new molten salt reactor concept developed by US start-up Transatomic could change the face of nuclear power. Molten Salt Reactors (MSR) with the fuel dissolved in the liquid salt and fluoride-salt-cooled High-temperature Reactors (FHR) have many research themes in common. Of the fourth generation reactors, the most suitable for thorium would be the Molten Salt Reactor (MSR). Molten Salt Reactors is a comprehensive reference on the status of molten salt reactor (MSR) research and thorium fuel utilization. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Indian Molten Salt Breeder Reactor (IMSBR) An 850 MWe IMSBR is being designed and developed in BARC ( Dulera et al. It was shelved by the Nixon Administration. 3. Among the most innovative of next generation reactors is the traveling wave reactor, designed by TerraPower, a company founded by none other than Bill Gates. They are seen as a promising technology today principally as a thorium fuel cycle prospect or for using spent LWR fuel. To move on from the design of the early 60s, Flibe’s LFTR uses a liquid fluoride salt that serves both as fuel carrier and coolant. 10 is being studied with goals of enhanced safety, efficient resource utilisation and high efficiency power conversion. India has such a reactor up and running as a test rig, and China, with all its environmental problems has around 300 researchers investigating the best processes for using Thorium in a reactor. A little-known type of nuclear reactor called the “molten salt reactor” (MSR), in which nuclear fuel is dissolved in a liquid carrier salt, was proposed in the 1940s and developed at the Oak Ridge National Laboratory in the 1960s. A cutaway of the IMSR core. Leslie Dewan of Transatomic Power testifies to the stifling effect this has on raising private investment to fund Molten-Salt Reactor research, and the resulting imputus to license and build Thorium Molten Salt Reactor A viable pathway to a carbon free energy system Thorium molten salt reactors have the potential to offer abundant, affordable, safe and clean energy for thousands of years. the U.

It was invented during the 1950s and 1960s in Oak Ridge Labs, but was quickly abandoned since the nuclear reactions were found to be not good for bomb-making. 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. S. MOLTEN SALT REACTOR 3 The MSR is designed such that if the molten salt is overheated, freeze-plugs at the bottom of the reactor will melt and all the fuel salt will drain into passively cooled The Detroit Molten Salt reactor was thorium based and utilized for destruction of nuclear ordinance. MOLTEN SALT REACTOR 3 The MSR is designed such that if the molten salt is overheated, freeze-plugs at the bottom of the reactor will melt and all the fuel salt will drain into passively cooled That was the purpose of the Molten-Salt Reactor Experiment: to demonstrate that some of the key features of the proposed molten-salt power reactors could be embodied in a practical reactor that could be operated safely and reliably and be maintained without excessive difficulty. Molten salt reactors are well suited to thorium fuel, as normal fuel fabrication is avoided. • Bilateral cooperation with ITU, POLIMI, CTU Prague, Terrestrial Energy, … • NES Division Project on Gen‐IV MSR (umbrella for several project). O'Hagan advocates for the use of liquid thorium fuel in high-temperature molten salt reactors. The thorium reactors would 1. Molten salt is used instead of water in the reactor making it much safer, salt cools and solidifies instead of leaking into the sea as in Japan right now (and no way to stop it). When the reactor is shut down, the fuel drains to a tank called the drain tank, which contain the fuel when the reactor is not in operation, or during an emergency. Terrestrial Energy USA, a company that is developing a fourth-generation molten salt nuclear reactor, has joined forces with Southern Co. This is the first of a three-part series by Carolyn Krause on the Molten Salt Reactor history. Should something go wrong the plug melts and the molten salt drains into a shielded underground container. The main difficulties in developing this kind of MSR is the online processing of the fuel salts and the corrosion of components. The Molten Salt Reactor. Terrestrial Energy USA has partnered with utility Southern Company and several U. The team at NRG is testing several reactor designs on a small scale at first. Molten salt reactor technology has attracted private funding over the last few years, and several reactor concepts are under development. Terrestrial is far from alone. D. The development of LFTRs was soon mothballed because they did not produce very much of the plutonium required to feed the nuclear arms race between the US and the USSR. Source: Terrestrial Energy USA. This paper gives an overview of the international R&D efforts on these reactor types carried out in the framework of Generation-IV. India has recently started carrying out fundamental studies so as to arrive at a conceptual design of Indian molten salt breeder reactor (IMSBR). Is the future of nuclear power molten SALT? ‘Safer’ thorium reactor trials carried out for the first time for 40 years Dutch firm NRG has revealed plan to test reactors that use molten salt as in the U. to build a molten-salt reactor that could replace the 1970s-era technology in today’s nuclear power plants and help wean China off the coal that fouls the air of For example, a molten-salt reactor needs only a ton of U233 to operate at 1GWe for a year, running a city. Dissolving the thorium salts into this molten liquid and irradiating it with neutrons to kick off the transmutation is one way to extract energy from the process. Alvin Weinberg, pioneer of today's most common reactor (PWR), lead research on the Molten Salt Reactor Experiment (MSRe) at ORNL from '65-'69 without signifcant flaw, and advocated for continued MSRe research, only to have his project's funds diverted to a breeder reactor as the breeder reactor could produce weapons grade material for the cold war. The benefits liquid metal thorium reactors have over light water uranium reactors have been compelling since the dawn of the The reactors all use solid thorium-uranium fuel cooled by molten salt and are one of the key reactor technologies identified for research by the Generation IV International Forum, which sees 13 countries and regions collaborate in the development of Generation IV nuclear energy systems. 4, Number 2, June 2013 81 abundance or widely available in the world, and such a simple description consequently causes Professor Li, director of the project's molten salt chemistry and engineering technology division, said the smog crisis had provided huge impetus for their research. , 2013 , Vijayan et al. India holds the largest thorium The country has committed to spending $3. A fast-neutron reactor (FNR) or simply a fast reactor is a category of nuclear reactor in which the fission chain reaction is sustained by fast neutrons (carrying energies of 5 MeV or greater), as opposed to thermal neutrons used in thermal-neutron reactors. This radioactive slurry could potentially reach very high temperatures, which translates to a A molten salt reactor (MSR) is a class of generation IV nuclear fission reactor in which the primary nuclear reactor coolant, or even the fuel itself, is a molten salt mixture. The main MSR concept is to have the fuel dissolved in the coolant as a fuel salt that is continuously circulated through the primary system and into a “reactor vessel” where a controlled criticality is maintained to produce useful power. Fail-Safe Nuclear Power. • Molten salt is an ideal reactor material because: • After startup, Load throttles reaction-rate via natural salt expansion with temp • ~30% better thermal efficiency than best PWR/BWR plant The inspiration is the work the United States' Oak Ridge National Laboratory (ORNL) did by building and operating 2 successful Molten Salt Reactors (Nuclear Reactors) in 1954 (the ARE) and the 1960s (the MSRE).

Once complete, it will usher in the second phase of India’s three-stage plan to achieve Dr Ian Scott, inventor of Stable Salt Reactor Technology, has addressed Oak Ridge National Laboratory as part of ORNL’s commemoration of the 50th anniversary of the Molten Salt Reactor Experiment’s first operation. Irradiation tests on a mixture of lithium and thorium fluoride salts are under way at the High Flux Reactor at Petten in the Netherlands. As an MSR fuel salt is a liquid, it functions as both the fuel (producing the heat) and the coolant (transporting the heat away and ultimately to the power plant). Molten salt reactors (MSRs) use molten fluoride salts as the primary coolant. • In 2015, Switzerland joined the GIF Molten Salt Reactor Project. The SALt Irradiation ExperimeNT, or SALIENT, has been prepared in cooperation with the European Commission Laboratory the history of the molten salt reactor developed at the Oak Ridge National Laboratory. Paris Innovation Review – The concept of molten salt reactors associated with the thorium cycle, sometimes referred to as Molten Salt Fast Reactors (MSFRs) is a newcomer among Generation IV reactor designs. The 2-unit HTR-PM demonstration power plant is scheduled to start up in late 2017. The molten salt design being developed at NRG is known as the Salt Irradiation Experiment (SALIENT). molten salt reactor india
