A preliminary systems assessment of the Starlite Demo candidates

The Starlite project has evaluated the following five tokamaks as candidates for the US Demo Power Plant: 1) steady state, first stability regime; 2) pulsed, first stability regime; 3) steady state, second stability regime; 4) steady state, reversed shear; and 5) steady state, low aspect ratio. Systems analysis of these candidates has played an important role in the selection of a reversed-shear tokamak for further conceptual design as a US Demo Power Plant. The cost-based systems analysis that led to the selection of a reversed-shear tokamak is described herein.
