The advanced SSTR

A reactor concept is proposed to improve economical competetiveness of the tokamak fusion reactor with agressive physics and engineering assumptions. Key elements are high field magnets with Bmax=21 T with high normalized beta βN=4.2 with 80% bootstrap current fraction and short throat radiative divertor. The power plant should have large net electric power of 3.4 GWe with twin tokamak reactor. Significant simplification of tokamak auxiliary system is also required.
