Oak Ridge TNS program: context, scope, and baseline design of the FY 1978 activities

Abstract

A status report on the Oak Ridge TNS Program has been prepared with three basic parts--a summary of the FY 1977 activities, a discussion of the current baseline design, and a statement of work tasks for FY 1978. Within the FY 1977 activities, the plasma engineering efforts were directed toward improving the economical performance of tokamak reactors and toward easing the requirements placed upon the supporting technology development programs. The FY 1977 systems modeling efforts were used to develop comprehensive systems models for cost comparison of different toroidal field (TF) coil technology options. The FY 1977 program planning tasks provided a draft program plan with both an R and D assessment and schedule considerations. On the basis of these activities, the FY 1978 effort is being directed toward initiation of preconceptual design. The current baseline design, characterized by key parameters and overall layout drawings, is being developed from the FY 1977 activities as a starting point for the FY 1978 preconceptual design study tasks. The projected performance of the baseline design as an ignited and burning primitive fusion reactor facility is being developed through self-consistent plasma engineering calculations using 0-D, 1-D, and 1-/sup 1///sub 2/-D models. A set of pertinentmore » work tasks for the FY 1978 effort has been developed from a systematic analysis of the status of each subsystem.« less
