ITER Organization, Fusion For Energy, the European Union organisation responsible for the European contribution to the ITER programme and Groupe VINCI have announced the completion of civil engineering works on the ITER Tokamak2 Building at the Saint Paul lez Durance Cadarache site in south-eastern France. This major project milestone was symbolically reached with the final concrete pour, on 7 November 2019, of the upper part of the building in which the ITER Tokamak will soon be assembled. With the on-time completion of the Tokamak Building civil engineering works, the metal frame of the roof can be installed and the ambitious First Plasma3 target in 2025 maintained.

The civil engineering project, which got under way in 2010, called for exceptional complex project management capabilities and cutting-edge expertise.

The teams working within the VINCI-led consortium set up an efficient and agile project organisation enabling them to integrate all design changes requested by the ITER scientific teams as construction proceeded. The mobilisation of the VINCI design and works teams, the use of cutting-edge digital design tools and the complex project management expertise of the VINCI teams made this successful system possible.

The construction of the 73 metre high, 120 metre wide Tokamak Building also required production of highly specific concretes. The worksite teams developed about 10 formulations, some of which have unique features enabling them to shield workers and the environment from fusion-generated radiation. Some parts of the Tokamak Building also called for steel reinforcement density rarely used on projects on this scale (up to 10 times the density of an apartment building wall). Lastly, access to the heart of the Tokamak Building required customised production of 46 heavy nuclear doors. Each 70-tonne door is manufactured in Germany, brought to the site, filled with concrete and assembled in the heart of the Tokamak Building.
