Potain tower cranes are building one of the world's largest experimental nuclear fusion reactors at a huge site in the South of France. Built from stainless steel sections which have thicknesses ranging from 50 mm to 250 mm, the ITER fusion reactor will house the systems necessary for the operation of the ITER Tokamak device. The Tokamak complex is where the nuclear power will be generated. It consists of a seven-story concrete building measuring 120 m long and 80 m wide. There will be 16,000 t of rebar, 150,000 cu m of concrete and 7,500 t of steel in the structure.

The six Potain cranes working on the 300 million project include two topless tower cranes an MDT 308 and an MDT 368 - and four traditional top-slewing tower cranes, the MD 610 M40, MD 485 B, MD 560 B and the MD 175. The cranes were supplied new to Dodin Campenon Bernard, a subsidiary of contracting giant Vinci Construction, which is managing all lifting work on site.
