Abstract: This paper concentrates on the key scientific issues during the experimental phase of magnetic confinement fusion and the main challenges in the fusion engineering process. It mainly discusses the development history and current status of both domestic and international Tokamak devices, detailing their basic parameters, main goals, important achievements, current research interests, and development plans. Research on magnetic confinement fusion worldwide has been moving from plasma experiments to the development of fusion reactor engineering and technology. Speeding up the creation of an industry focused on fusion energy development is essential for the progress of controlled nuclear fusion technology. This paper also analyzes the future development direction and technology options for magnetic confinement fusion Tokamak, and summarizes the important areas in nuclear engineering and technology that should be addressed quickly to speed up the development of fusion.
