Parametric studies have been performed as part of the General Atomic/Argonne National Laboratory TNS scoping effort to aid in the selection of initial conceptual design parameters. A system analysis computer code, SCOPE, which incorporates plasma physics models to describe the plasma ignition and burn performance, and engineering and costing algorithms to define and cost the reactor components, support systems, and balance of plant was the primary tool utilized in the parametric studies. Studies were performed for moderate burn time (30 sec), low duty factor (0.1) ignition test reactors. Doublet shaped plasmas were assumed for high ..beta.. (10%) operation, and based upon power and cost considerations derived in separate TNS scoping studies, superconducting toroidal field coils were assumed. Surveys over a broad range of parametric space indicated that minimum cost machines are obtained for maximum fields of 8 to 10 tesla at the TF coils, with larger, more costly machines resulting at higher and lower fields. Major radii of 3.5 to 4.0 meters are required, with the size increasing for higher margin machines. Investigations of normal conducting and superconducting OH coils over the narrower parameter range of interest indicated a strong cost incentive for incorporating superconducting coils. On the basis of these parametric studies, a 3.8 m major radius, 1.1 m minor radius Ignition Test Reactor was selected as an initial conceptual design for TNS.
