This 9th edition of the ITER Open Doors Day is the opportunity for the public to discover the latest construction progress on the ITER site. The gigantic Assembly Hall, where the main components of the ITER Tokamak will be prepared and pre-assembled, now dominates the ITER site. Its structure has been finalized and the two main cranes, which will carry loads of up to 1,500 tonnes to the Tokamak installation area, have been installed. Work on the Tokamak Complex, future home to the ITER fusion device, is also progressing steadily and in the Poloidal Field Coils Winding Facility, the first manufacturing activities are underway on the superconducting magnets that will help to shape the ITER plasma.

Visits will take place between 10:30 and 16:15

Please note that the 10:30 and the 11:00 bus tours will be in English only. From 11:30 onwards all bus tours will be in French only.
