ITER vacuum vessel assembly in France progresses steadily, with five European sectors at different critical stages
The vacuum vessel assembly work for the International Thermonuclear Experimental Reactor (ITER) project in southern France is progressing steadily. As the core component of the ITER tokamak device, the vacuum vessel will contain the plasma confined by superconducting magnets, serving as the critical space where fusion reactions occur. This stainless steel ring-shaped structure weighs approximately 5,200 tonnes in total, measures 19.4 meters in diameter, and consists of nine sectors, five of which are manufactured by Europe. The European Fusion for Energy organization (F4E), together with the AMW consortium comprising Ansaldo Nucleare, Westinghouse Electric Italy, and Walter Tosto Company, is responsible for the related manufacturing work.
