First vessel subassembly achieved in Europe
Nine massive steel sectors delivered by the Domestic Agencies of Europe (five sectors) and Korea (four sectors) will be welded together on site during the assembly phase to form the torus-shaped ITER vacuum vessel.
Manufacturing and welding activities are underway now on the many sub-parts that go into the final products—each 600-tonne sector is assembled from four smaller poloidal segments; these segments in turn are created by the welding together of different subassemblies.
