The design of a core plasma with the LHD-type heliotron configuration has been advanced. Recent design study of a LHD-type heliotron reactor has shown that the increase in the reactor size is a possible solution to secure a sufficient blanket space. The increase in the reactor size enables a flexible selection of plasma configurations. In this respect, a commercial plant design with the plasma configuration which has a similar shape to that of LHD high-beta plasma discharge was carried out. A parametric scan with a system design code showed that there exists the design window with engineering constraints and the physics constraints which can be extrapolated from the present experimental achievements. Finite-beta equilibrium calculations by VMEC code showed that the last closed flux surface which has almost the same shape as that in vacuum equilibrium can be obtained by applying an appropriate additional vertical field (© 2010 WILEY-VCH Verlag GmbH & Co.
