Introduction  Using nuclear fusion to generate electricity is a promising way for nuclear energy in the future. In order to research the best civil structure design, it is necessary to discuss techniques from fossil fuel power plant and conventional island of other NPPs.

  Method  Through comparation analysis, structure system of main building, roof structure, TG foundation and fire protection design were discussed.

  Result  Conceptual design for civil structure and engineering advice are also given.

  Conclusion  The research in this paper can provide reference for similar project.
