Trade Study Analysis for TNS Tokamaks
- Westinghouse Electric Corp., Pittsburgh, PA (United States)
A series of parametric trade studies was performed to consistently evaluate the relative.costs and performance parameters of D-T burning tokamaks over a range of plasma sizes and toroidal field (TF) coil technologies. Four different types of TF coil technologies were investigated: water-cooled copper coils, superconducting NbTi and Nb3Sn coils, and a "hybrid" coil arrangement consisting of a· normal conducting Cu coil nested within a superconducting NbTi coil. Results of the analysis indicate for TNS operation, for example, that for a given plasma beta at ignition, the Cu TF coil devices are least expensive, followed by the Nb3Sn, NbTi, and NbTi/Cu options. Other conclusions and trends resulting from the study are presented and analyzed.
