You can unsubscribe at any time and we'll never share your details to third parties. A series of papers suggest the MIT SPARC fusion reactor is likely to work. Overall, "we're still aiming for a start of construction in roughly June of '21," Greenwald says. What we're trying to do is put the project on the firmest possible physics basis, so that we're confident about how it's going to perform, and then to provide guidance and answer questions for the engineering design as it proceeds.". In short, he says, "one of the conclusions is that things are still looking on-track. Their experimental version (SPARC) is going to be a lot smaller than the current experiment being … or, by Sarah McDonnell, Massachusetts Institute of Technology. Read More . Do you think quantified things exist in reality? We do not guarantee individual replies due to extremely high volume of correspondence. "Most of the physical variables that act as obstacles to commercialization appear within 300 seconds after the plasma temperature rises to 100 million degrees." Studying the behavior of this burning plasma—something never before seen on Earth in a controlled fashion—is seen as crucial information for developing the next step, a working prototype of a practical, power-generating power plant. Greenwald wrote the introduction for a set of seven research papers authored by 47 researchers from 12 institutions and published today in a special issue of the Journal of Plasma Physics. But decades of research toward such power-producing plants have still not led to a device that produces … Many of the fine details are still being worked out on the machine design, covering the best ways of getting energy and fuel into the device, getting the power out, dealing with any sudden thermal or power transients, and how and where to measure key parameters in order to monitor the machine's operation. PSFC. Quite the same Wikipedia. It is a much smaller nuclear fusion reactor which could be built much more quickly. The high power in a small size is made possible by advances in superconducting magnets that allow for a much stronger magnetic field to confine the hot plasma.

We believe it's going to work.". April 10, 2020. SPARC is planned to be the first experimental device ever to achieve a "burning plasma"—that is, a self-sustaining fusion reaction in which different isotopes of the element hydrogen fuse together to form helium, without the need for any further input of energy. En dépit d'être un appareil relativement compact, SPARC est conçu pour répondre à cette mission avec de la marge et peut être capable de produire jusqu'à 140 MW de puissance de fusion par rafales de 10 secondes[1],[6]. SPARC would be the size of existing mid-sized fusion devices, but with a much stronger magnetic field. Minimum browser requirements are; Internet … It is designed to achieve a Q factor—a key parameter denoting the efficiency of a fusion plasma—of at least 2, essentially meaning that twice as much fusion energy is produced as the amount of energy pumped in to generate the reaction. The class called it the ARC (affordable, robust, compact) fusion reactor. The quest for practical fusion energy sources. Greenwald says there is still much to be learned about the physics of burning plasmas, and once this machine is up and running, key information can be gained that will help pave the way to commercial, power-producing fusion devices, whose fuel—the hydrogen isotopes deuterium and tritium—can be made available in virtually limitless supplies. SPARC Version 8 (V8), an enhanced SPARC architecture definition, was released in 1990. ", The publication of this special issue of the journal, he says, "represents a summary, a snapshot of the physics basis as it stands today." Share on Facebook; Share on Twitter; Share via Email; International Open Access Week Open Access . Redundancy enables continuous operations. The estimated cost of an ARC reactor that matched the ITER-predicted performance was only a few billion dollars—as little as a tenth of ITER’s price tag. May 11, 2020 . Starting in 1993, MIT has been running a tokamak reactor called C-Mod only for exper… The details of the burning plasma "are really novel and important," he says. Fusion harnesses the reaction that powers the sun itself, holding the promise of eventually producing clean, abundant electricity using a fuel derived from seawater — deuterium, a heavy form of hydrogen, and lithium — so the fuel supply is essentially limitless. Le but est d'avoir un gain de fusion Q supérieur à 2. "The big mountain we have to get over is to understand this self-heated state of a plasma. Share.

David Chandler, with the MIT news office, published a press release on March 9, 2018, promoting a new fusion reactor design called SPARC. The main differences between V7 and V8 were the addition of integer multiply and divide instructions, and an upgrade from 80-bit "extended precision" floating-point arithmetic to 128-bit "quad-precision" arithmetic. ARC is a concept for a fusion pilot plant that could produce 500 MW of fusion power and over 200 MW of electricity in a device roughly the size of the JET tokamak 4 they are for all practical fusion schemes, since economics dictate a high average neutron wall loading and thus an over all high fusion power … The papers also describe the use of calculations and simulation tools for the design of SPARC, which have been tested against many experiments around the world. Just better. SPARC propose d'utiliser des aimants puissants construits avec un nouveau supraconducteur à haute température d' oxyde de cuivre et d'yttrium baryum (YBCO) afin de produire des plasmas qui génèrent deux fois plus d'énergie que l'énergie requise pour maintenir le plasma à des températures élevées (200 millions de Kelvin)[5].
