Feasibility of commercial tokamak reactors is discussed. The range of cost of electricity (COE) by competitors of fusion is estimated and the target range of COE for the fusion reactors is proposed. It is shown that the high β advanced plasma mode will break through this COE target. As a possible path toward the cost competitive tokamak concepts, the reactor compact reversed shear tokamak (CREST), which is based on the high β plasma and super-heated steam cycle, is briefly reviewed.
