ELMO Bumpy Torus Reactor

The design bases and interim results of a conceptual design study of the ELMO Bumpy Torus Reactor (EBTR) are described. By direct coupling of critical engineering constraints, fundamental (neoclassical) transport processes, stability-related beta limits, electron-ring heating and classical loss processes, magnet design and blanket/shield performance, an EBTR design emerges that generates 1270-MWe gross power in a system with a toroidal radius of 35 m using aspect-ratio-enhancement coils. Although the conceptual engineering of this high-Q system is not complete, interim designs and solutions are presented. A summary of key physics and engineering issues requiring further investigation is also given
