Abstract

Based on scientific knowledge available from ITER plasmas and advancement of fusion nuclear technology from the near-term R&D program, a low wall-loading DEMO fusion reactor has been designed, where high priority has been given to the early and reliable realization of a tokamak fusion plasma over the cost performance. Since a major radius of this DEMO reactor is increased up to 10 m, a plasma ignition is achievable with a low fusion power of 0.8 GW and an operation period of 4 approx. 5 hours is available only with inductive current drive. The low ignition power makes it possible to adopt an austenitic stainless steel, which have a plenty of experiences under the neutron irradiation in fission reactors. In step with development of advanced materials, step-wise increase of the fusion power seems to be feasible and realistic, because this DEMO reactor has a potentiality to produce a fusion power of approx. 5 GW.
