Research on tokamak conceptual design based on cooperative template

R&D of fusion energy is becoming more and more important in the world. Up to now, tokamak is a typical fusion experiment device using magnetic confinement. Although the recent experiments and associated theoretical studies of fusion energy development have proven the feasibility of fusion power, it's commonly realized that it needs hard work before fusion energy could be commercially and economically utilized. It means that there will many new concepts and schemes to be supported and to be optimized. The paper studies stages of conceptual design and introduces a method of cooperative template. A novel idea and methodology of computer aided conceptual design is proposed according to characteristics of function, behavior and structures in tokamak.
