“…We focus on the burning plasma control scenario to access to the ignition regime and to sustain the steady-state burn including radial plasma profile change. Here, 2 or 3-dimensional (2-D or3-D) equilibrium and 1-dimensional (1-D) predictive transport code TOTAL (toroidal transport analysis linkage) [6][7][8] for tokamak and helical systems has been used. In this case the profile effect on the ignition attainment is very important, and the transport analysis coupled with equilibrium analysis should be carried out.…”

“…(3b) is for helical data treatment. Using this model, the analyses have already been carried out focusing on high-field-side pellet injection effects to make easy access to ITB regime [8]. The neoclassical tearing mode and impurity transport are also investigated using this TOTAL code [11][12].…”

Reference 1-GWe D-T reactors; tokamak TR-1, spherical tokamak ST-1 and helical HR-1 reactors, are designed using PEC (Physics Engineering Cost) code, and their plasma behaviors with Internal Transport Barrier (ITB) operations are analyzed using TOTAL (Toroidal Transport Analysis Linkage) code, which clarifies the requirement of deep penetration of pellet fueling to realize steady-state advanced burning operation. In addition, economical and environmental assessments were performed using extended PEC code, which shows the advantage of high beta tokamak reactors in COE and the advantage of compact spherical tokamak in lifetime CO 2 emission reduction. Comparing with other electric power generation system, the cost of fusion reactor is higher than that of fission reactor, but on the same level of oil thermal power system. The CO 2 reduction can be achieved in fusion reactors same as in the fission reactor. The EPR of high-beta tokamak reactor TR-1 could be higher than that of other systems including fission reactor. These systematic design and comparative simulation analyses on both tokamak and helical reactors can be done by the help of the above two codes.
