Assembly of ITER begins in Southern France

Those attending the livestreamed July 28 celebration in person (shown here from above) followed recommended social distancing measures.

First-of-a-kind components have been arriving in recent months at the ITER construction site in Cadarache, France, from some of the 35 ITER member countries around the world. The arrival on July 21 of the first sector of the ITER vacuum vessel from South Korea marks the beginning of a four-and-a-half year machine assembly process for the world’s largest tokamak, a magnetic fusion device designed to prove the feasibility of fusion as an energy source.

ITER, the world’s largest international scientific collaboration, is beginning the assembly of the fusion reactor tokamak that will include 12 essential hardware systems provided by US ITER, which is managed by Oak Ridge National Laboratory. The first major machine element to be installed is the 1,250-ton base of the cryostat, which was placed into the tokamak assembly pit on May 26. ITER is located in southeastern France.
