Download or read book ITER International Thermonuclear Experimental Reactor Physics Basis written by and published by . This book was released on 1990 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics basis of ITER has been developed from an assessment of the present knowledge of tokamak physics with allowance for improvements in that knowledge during the design and construction phases of ITER. The assessment has been carried out by the ITER design team in collaboration with the international fusion program, including participation by the experimental teams of all of the major toroidal experiments. The physics basis consists of guidelines for energy confinement, operational limits, power and particle control, disruptions, current drive and heating, alpha particle physics, and plasma control. The ITER physics group has worked with the engineering groups to implement these guidelines. In addition, a preliminary design for the plasma diagnostics for ITER has been developed and an operational program has been planned. In many cases, the physics issues have not been fully resolved, and a physics R D program has been developed to complete the physics basis for ITER. 16 refs., 3 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The International Thermonuclear Experimental Reactor (ITER) team is completing the second year of a three-year conceptual design phase. The purpose of ITER is to demonstrate the scientific and technological feasibility of fusion power. It is to demonstrate plasma ignition and extended burn with steady state as the ultimate goal. In so doing, it is to provide the physics data base needed for a demonstration tokamak power reactor and to demonstrate reactor-relevant technologies, such as high-heat-flux and nuclear components for fusion power. To meet these objectives, many design compromises had to be reached by the participants following a careful review of the physics and technology base for fusion. The current ITER design features a 6-m major radius, a 2.15-m minor radius and a 22-MA plasma current. About 330 volt-seconds in the poloidal field system inductively drive the current for hundreds of seconds. Moreover, about 125 MW of neutral-beam, lower-hybrid, and electron-cyclotron power are provided for steady-state current drive and heating all these systems are discussed in this paper. 3 refs., 6 figs., 7 tabs.
Download or read book ITER International Thermonuclear Experimental Reactor Physics Design Guidelines written by and published by . This book was released on 1990 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics requirements for the ITER design have been set to provide reasonable assurance that the plasma performance will be sufficient to meet the goals of ITER in both physics and technology phases of operation. Considerations for an adequate level of energy confinement with a stable plasma, a satisfactory power and particle control system, an efficient heating and current drive scheme, a suitable plasma control system, a sufficient level of volt-seconds, a need for high-fluence burn, etc., along with several engineering and technology, constraints, set the machine parameters (current, size, field, etc.) The physics guidelines for the ITER design are based on reasonable extrapolations of the tokamak physics database as assessed during the ITER Conceptual Design Activities (1988--90). The reference ITER design has a nominal plasma current of 22 MA (with capability up to 25--28 MA for limited pulse duration), magnetic field of 4.85 T, major radius of 6 m, minor radius of 2.15 m, and a plasma elongation (at the 95% flux surface) of (approximately)2 that produces a nominal fusion power of (approximately)1 GW. 17 refs., 1 tab.

Download or read book DEVELOPMENT PHYSICS BASIS AND PERFORMANCE PROJECTIONS FOR HYBRID SCENARIO OPERATION IN ITER ON DIII D written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new standard in stationary tokamak performance is emerging from experiments on DIII-D. These experiments have demonstrated the ability to operate near the free boundary, n = 1 stability limit with good confinement quality under stationary conditions. The normalized fusion performance is at or above that projected for Q[sub fus] = 10 operation in the International Thermonuclear Experimental Reactor (ITER) design over a wide operating range in both edge safety factor (3.2-4.5) and plasma density (35%-70% of the Greenwald density). Projections to ITER based on this data is uniformly positive and indicate that a wide range of operating options may be available on ITER, including the possibility of sustained ignition. Recent experiments have demonstrated the importance of a small m=3, n=2 neoclassical tearing mode in avoiding sawteeth and the effect of edge localized modes on tearing mode stability at an edge safety factor near 3. Transport studies using the GLF23 turbulence transport code indicate that E x B stabilization is important in reproducing the measured profiles in the simulation. Yet, even in cases in which the toroidal rotation is low, confinement quality is robustly better than the standard H-mode confinement scalings.

Download or read book The Fairy Tale of Nuclear Fusion written by L. J. Reinders and published by Springer Nature. This book was released on 2021-05-20 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: This carefully researched book presents facts and arguments showing, beyond a doubt, that nuclear fusion power will not be technically feasible in time to satisfy the world's urgent need for climate-neutral energy. The author describes the 70-year history of nuclear fusion; the vain attempts to construct an energy-generating nuclear fusion power reactor, and shows that even in the most optimistic scenario nuclear fusion, in spite of the claims of its proponents, will not be able to make a sizable contribution to the energy mix in this century, whatever the outcome of ITER. This implies that fusion power will not be a factor in combating climate change, and that the race to save the climate with carbon-free energy will have been won or lost long before the first nuclear fusion power station comes on line. Aimed at the general public as well as those whose decisions directly affect energy policy, this book will be a valuable resource for informing future debates.
Download or read book Iter Physics written by C Wendell Horton, Jr and published by World Scientific. This book was released on 2015-06-25 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The promise of a vast and clean source of thermal power drove physics research for over fifty years and has finally come to collimation with the international consortium led by the European Union and Japan, with an agreement from seven countries to build a definitive test of fusion power in ITER. It happened because scientists since the Manhattan project have envisioned controlled nuclear fusion in obtaining energy with no carbon dioxide emissions and no toxic nuclear waste products.This large toroidal magnetic confinement ITER machine is described from confinement process to advanced physics of plasma-wall interactions, where pulses erupt from core plasma blistering the machine walls. Emissions from the walls reduce the core temperature which must remain ten times hotter than the 15 million degree core solar temperature to maintain ITER fusion power. The huge temperature gradient from core to wall that drives intense plasma turbulence is described in detail.Also explained are the methods designed to limit the growth of small magnetic islands, the growth of edge localized plasma plumes and the solid state physics limits of the stainless steel walls of the confinement vessel from the burning plasma. Designs of the wall coatings and the special 'exhaust pipe' for spent hot plasma are provided in two chapters. And the issues associated with high-energy neutrons — about 10 times higher than in fission reactions — and how they are managed in ITER, are detailed.
Download or read book Star Power written by Alain Bécoulet and published by MIT Press. This book was released on 2023-09-19 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: A concise and accessible explanation of the science and technology behind the domestication of nuclear fusion energy. Nuclear fusion research tells us that the Sun uses one gram of hydrogen to make as much energy as can be obtained by burning eight tons of petroleum. If nuclear fusion—the process that makes the stars shine—could be domesticated for commercial energy production, the world would gain an inexhaustible source of energy that neither depletes natural resources nor produces greenhouse gases. In Star Power, Alan Bécoulet offers a concise and accessible primer on fusion energy, explaining the science and technology of nuclear fusion and describing the massive international scientific effort to achieve commercially viable fusion energy. Bécoulet draws on his work as Head of Engineering at ITER (International Thermonuclear Experimental Reactor) to explain how scientists are trying to “put the sun in a box.” He surveys the history of nuclear power, beginning with post–World War II efforts to use atoms for peaceful purposes and describes how energy is derived from fusion, explaining that the essential principle of fusion is based on the capacity of nucleons (protons and neutrons) to assemble and form structures (atomic nuclei) in spite of electrical repulsion between protons, which all have a positive charge. He traces the evolution of fusion research and development, mapping the generation of electric current though fusion. The ITER project marks a giant step in the development of fusion energy, with the potential to demonstrate the feasibility of a nuclear fusion reactor. Star Power offers an introduction to what may be the future of energy production.

Download or read book Burning Plasma written by National Research Council and published by National Academies Press. This book was released on 2004-04-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant advances have been made in fusion science, and a point has been reached when we need to decide if the United States is ready to begin a burning plasma experiment. A burning plasmaâ€"in which at least 50 percent of the energy to drive the fusion reaction is generated internallyâ€"is an essential step to reach the goal of fusion power generation. The Burning Plasma Assessment Committee was formed to provide advice on this decision. The committee concluded that there is high confidence in the readiness to proceed with the burning plasma step. The International Thermonuclear Experimental Reactor (ITER), with the United States as a significant partner, was the best choice. Once a commitment to ITER is made, fulfilling it should become the highest priority of the U.S. fusion research program. A funding trajectory is required that both captures the benefits of joining ITER and retains a strong scientific focus on the long-range goals of the program. Addition of the ITER project will require that the content, scope, and level of U.S. fusion activity be defined by program balancing through a priority-setting process initiated by the Office of Fusion Energy Science.
