Plasma physics design and major specifications of candidate reactors for FER design studies

Physics design and reference options of FER (Fusion Experimental Reactor) for FY86 conceptual design study are presented. As for physics design, emphases are placed on the data base, from which physics design constraints different from those of FY84 and 85, have been derived. Wide parametric studies are done for the cost-effectiveness to select the reference options. They are (i) reduction of volt · second, (ii) noncircularity, (iii) shield thickness, (iv) magnet design constraints, (v) partial usage of normal conducting OH coils, (vi) impact of the access method to the reactor core component on the capacity of PF coil system. Based on these studies, various system quantities are evaluated and five reference options are selected. Reference options for FY86 conceptual design consist of these options in addition to the NBI reactor. (author)
