Abstract
The application discloses a vacuum chamber of a nuclear fusion device and the nuclear fusion device, and relates to the nuclear technology field, which comprises a vacuum chamber body, the vacuum chamber body comprising: an inner wall, an outer wall, the inner wall being connected with the outer wall and jointly defining a vacuum chamber interlayer; a shielding structure, the shielding structure being arranged in the vacuum chamber interlayer; and a connecting structure, the connecting structure being arranged in the vacuum chamber interlayer and being connected with the vacuum chamber body, the connecting structure being configured to fix the shielding structure, the shielding structure comprising: a plurality of shielding plates, the plurality of shielding plates being arranged along the thickness direction of the inner wall; and an insulating layer being arranged between every two adjacent shielding plates and at the end of the outermost shielding plate away from the rest of the shielding plates. By arranging the shielding structure in the vacuum chamber interlayer, the neutrons can be effectively shielded, and the service life of the nuclear fusion device is prolonged. Moreover, by arranging the connecting structure, the shielding structure can be stably fixed, and the installation firmness is good. In addition, the structure is exquisite, and the vacuum chamber can be applied to various sizes, and the universality is high.
