This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We have made a preliminary design of a D-T fusion reactor blanket and MHD power conversion system based on the CFAR concept, and found that the performance and costs for the reference cycle are very attractive. While much remains to be done, the potential advantage of liquid metal Rankine cycles for fusion applications are much clearer now. These include low pressures and mass flow rates, a nearly isothermal module shell which minimizes problems of thermal distortion and stresses, and an insensitivity to pressure losses in the blanket so that the two-phase MHD pressure drops in the boilling part of the blanket and the ordinary vapor pressure drops in the pebble-bed superheating zones are acceptable (the direct result of pumping a liquid rather than having to compress a gas). There are no moving parts in the high-temperature MHD power generators, no steam bottoming plant is required, only small vapor precoolers and condensers are needed because of the high heat rejection trmperatures, and only a relatively small natural-draft heat exhanger is required to reject the heat to the atmosphere. The net result is a very compact fusion reactor and power conversion system which fit entirely inside an 18 meter radius reactor vault. Although we have not yet performed a detailed cost analysis, preliminary cost estimates indicate low capital costs and a very attractive cost of electricity. 11 refs., 5 figs., 2 tabs.

This book was released on 1988 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CFAR (compact fusion advanced Rankine) cycle concept for a tokamak reactor involves the use of a high-temperature Rankine cycle in combination with microwave superheaters and nonequilibrium MHD disk generators to obtain a compact, low-capital-cost power conversion system which fits almost entirely within the reactor vault. The significant savings in the balance-of-plant costs are expected to result in much lower costs of electricity than previous concepts. This paper describes the unique features of the CFAR cycle and a high- temperature blanket designed to take advantage of it as well as the predicted performance of the MHD disk generators using mercury seeded with cesium. 40 refs., 8 figs., 3 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The Erice International School of Fusion Reactor Techno logy held its 1981 course on « Unconventional Approaches to Fusion » in combination with the IAEA Technical Committee meeting on « Critical Analysis of Alternative Fusion Concepts ». The two events took place in the second half of March with an overlap of a few days only. The present proceedings include the first week's papers; those presented during the second week will be summarised in Nuclear Fusion. Right from the beginning of the course, and in particular In R. Carruthers' opening talk, it was clear that an uncon ventional approach was considered stimulating insofar as its con ception presented advantageous aspects with respect to the To kamak. Indeed the Tokamak was recognized as an « imper fect frame of reference» (K. H. Schmitter) in the sense that, al though it deserves to be considered as a frame of reference for the other devices because it is the most advanced in the scientific demonstration of controlled thermonuclear fusion, as a fusion reactor, however, the Tokamak does not seem to be completely satisfactory either from an economic or from an operational point of view, if compared with that « enticing ogre », the proven fission reactor (less enticing to the public). Comparison of a Tokamak reactor with a PWR can be founded on considerations of such a basic nature that it becomes almost automatic to ask how far the various unconventional ap proaches to fusion are exempt from the Tokamak's drawbacks.

Available in PDF, EPUB and Kindle. Book excerpt: Driven Magnetic Fusion Reactors is a collection of papers from the Proceedings of the Course held in Erice-Trapani, Italy on September 18-26, 1978. This collection describes the reactor aspects, the devices, physics, and the common technologies of the ""mirrors"" and the ""two component Tokamaks"" approach. This book reviews the mirror approach, which is used in the magnetic fusion energy program in the U.S. This program focuses on the tandem mirror and field reversed mirror concepts. This book explains the physics of field reversed mirrors and the mirror fusion test facility. The mirror machine as capable of producing fusion reaction with many advantages compared to the mainline tokamak is also discussed. The text also describes other ways to construct a fusion reactor by using a small quantity of quadrupole minimum-B mirrors that are linked toroidally to form a closed-line containment system. This book then presents methods of operating a driven tokamak reactor using the beam heated tokamak BHT, the two-component TCT, and the hot ion tokamak. This collection also describes the roles of low-Q fusion devices, and that of the fission-fusion hybrid version. This text addresses the non-electrical applications of the fusion process that is being done in the U.S. Then this collection also discusses a global approach to the fuel cycles and the different energy strategies of the U.S., Europe, and Japan. This book addresses the many interests of nuclear physicists, nuclear engineers, scientists, students, and academicians in the field of advanced physics.

Book excerpt: The ARIES research program is a multi-institutional effort to develop several visions of tokamak reactors with enhanced economic, safety, and environmental features. Three ARIES visions are currently planned for the ARIES program. The ARIES-I design si a DT-burning reactor based on modest extrapolation from the present tokamak physics data base; ARIES-II is a DT-burning reactor which will employ potential advances in physics; and ARIES-III is a conceptual D-3He reactor. The first design to be completed is ARIES-I, a 1000 MWe power reactor. The key features of ARIES-I are: (1) a passively safe and low environmental impact design because of choice of low activation material throughout the fusion power core, (2) an acceptable cost of electricity, (3) a plasma with performance as close as possible to present-day experimental achievements, (4) a high performance, low activation, SiC composite blanket cooled by He, and (5) an advanced Rankine power cycle as planned for near term coal-fired plants. The ARIES-I research has also identified key physics and technology areas with the highest leverage for achieving attractive fusion power system.

Book excerpt: The Advanced Reactor Innovation and Evaluation Study (ARIES) is a community effort to develop several visions of the tokamak as a fusion power reactor. The aims are to determine its potential economics, safety, and environmental features and to identify physics and technology areas with the highest leverage for achieving the best tokamak reactor. The authors focus on the ARIES-1 design. Parametric systems studies show that the optimum first stability tokamak has relatively low plasma current (~12 MA), high plasma aspect ratio (~4-6), and high magnetic field (~24 T at the coil). ARIES-I is a 1000-MWe (net) reactor with a plasma major radius of 6.5 m, a minor radius of 1.4 m, a neutron wall loading of about 2.8 MW/m2, and a mass power density of about 90 kWe/tonne. The ARIES-I reactor operates at steady state using ICRF (ion-cyclotron range of frequency) fast waves to drive current in the plasma core and lower-hybrid waves for edge-plasma current drive. The ARIES-I blanket is cooled by He and consists of SiC-composite structural material, Li4SiO4 solid breeder, and Be neutron multiplier, all chosen for their low-activation and low-decay after-heat in order to enhance the safety and environmental features of the design. The ARIES-I design has a competitive cost of electricity and superior safety and environmental features.

Book excerpt: This paper first reviews briefly the status and plans for research in magnetic fusion energy and discusses the prospects for the tokamak magnetic configuration to be the basis for a fusion power plant. Good progress has been made in achieving fusion reactor-level, deuterium-tritium (D-T) plasmas with the production of significant fusion power in the Joint European Torus (up to 2 MW) and the Tokamak Fusion Test Reactor (up to 10 MW) tokamaks. Advances on the technologies of heating, fueling, diagnostics, and materials supported these achievements. The successes have led to the initiation of the design phases of two tokamaks, the International Thermonuclear Experimental Reactor (ITER) and the US Toroidal Physics Experiment (TPX). ITER will demonstrate the controlled ignition and extended bum of D-T plasmas with steady state as an ultimate goal. ITER will further demonstrate technologies essential to a power plant in an integrated system and perform integrated testing of the high heat flux and nuclear components required to use fusion energy for practical purposes. TPX will complement ITER by testing advanced modes of steady-state plasma operation that, coupled with the developments in ITER, will lead to an optimized demonstration power plant.
