Download The Physics of Tokamak Start-up Book in PDF, ePub and Kindle
Tokamak start-up on present-day devices usually relies on inductively induced voltage from a central solenoid. In some cases inductive startup is assisted with auxiliary power from electron cyclotron radio frequency heating. ITER, the National Spherical Torus eXperiment Upgrade and JT60, now under construction, will make use of the understanding gained from present-day devices to ensure successful start-up. Design of a spherical tokamak (ST) with DT capability for nuclear component testing would require an alternative to a central solenoid because the small central column in an ST has insufficient space to provide shielding for the insulators in the solenoid. Alternative start-up techniques such as induction using outer poloidal field coils, electron Bernstein wave start-up, coaxial helicity injection and point source helicity injection have been used with success, but require demonstration of scaling to higher plasma current.

Download Tokamak Reactor Startup Power Book in PDF, ePub and Kindle
Tokamak startup with ohmic heating (OH)-induced voltages requires rather large voltages and power supplies. On present machines, with no radiofrequency (rf)-assist provisions, hundreds of volts have been specified for their designs. With the addition of electron cyclotron resonant heating (ECRH) assist, the design requirements have been lowered. To obtain information on the cost and complexity associated with this ECRH-assisted, OH-pulsed startup voltage for ignition-type machines, a trade-off study was completed. The Fusion Engineering Device (FED) configuration was selected as a model because information was available on the structure. The data obtained are applicable to all tokamaks of this general size and complexity, such as the Engineering Test Reactor (ETR).

Download Tokamak Startup with Electron Cyclotron Heating Book in PDF, ePub and Kindle
Experiments are described in which the startup voltage in a tokamak is reduced by approx. 60% by the use of a modest amount of electron cyclotron resonance heating power for preionization. A 50% reduction in volt-second requirement and impurity reflux are also observed.

Download Tokamak Reactors for Breakeven Book in PDF, ePub and Kindle
Tokamak Reactors for Breakeven: A Critical Study of the Near-Term Fusion Reactor Program presents all possible aspects concerning the Tokamak line of research. This book examines the many significant implications of fusion research programs. Organized into five parts encompassing 29 chapters, this book begins with an overview of the mechanisms of anomalous loss in existing machines. This text then examines the environmental problems related to the use of large quantities of tritium. Other chapters consider the technology of superconducting Tokamak magnets, which provides challenging tasks both for specific developments in laboratories and hardware construction in industry. This book discusses as well the established program goal of the fusion program to develop and demonstrate pure fusion central electric power stations for commercial applications. The final chapter deals with the two types of reactors, namely, the liquid metal fast breeder reactors (LMFBR) and the high temperature reactors (HTR). This book is a valuable resource for scientists, engineers, and technologists.
