National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Compact Quasi-Axisymmetric Stellarator Reactor.

DE2004820108

Publication Date	2003
Personal Author	Ku, L. P.
Page Count	12
Abstract	We report the progress made in assessing the potential of compact, quasi-axisymmetric stellarators as powerproducing reactors. Using an aspect ratio A=4.5 configuration derived from NCSX and optimized with respect to the quasiaxisymmetry and MHD stability in the linear regime as an example, we show that a reactor of 1 GW(e) maybe realizable with a major radius .8 m. This is significantly smaller than the designs of stellarator reactors attempted before. We further show the design of modular coils and discuss the optimization of coil aspect ratios in order to accommodate the blanket for tritium breeding and radiation shielding for coil protection. In addition, we discuss the effects of coil aspect ratio on the peak magnetic field in the coils.
