An Economically Competitive Fusion Reactor

A reactor concept is proposed to improve economical competitiveness of the tokamak fusion reactor with aggressive physics and engineering assumptions. Key elements are high field magnets with B_max=21T with high normalized beta β_N=4.2 with 80% bootstrap current fraction and the radiative divertor. The power plant should have large net electric power (~3.4GWe) with twin tokamak reactors. Significant simplification of tokamak auxiliary system is also required.
