“…Based on the progress in the recent experiments and the associated theoretical studies of magnetic confinement fusion, and in the studies of fusion power plant concepts, such as US ARIES, EU PPCS, and the Japanese SSTR series fusion reactor concepts [8][9][10][11][12], as well as ITER, the core plasma parameters of FDS-II are initially designated and optimized by the SYSCODE [13], a coupled physics-engineering/cost-benefit computer system code, which was developed by the FDS team itself. With a major radius of 6 m and a minor radius of 2 m, the fusion power for FDS-II is ∼2.5 GW with 1 GW of electrical power, and the power gain Q reaches 30.…”
