In order to keep our readers up-to-date with the construction progress of ITER, we have decided to report periodically on key developments from the site and highlight the most important milestones.
So what is the state of play since our last report?
The Poloidal Field (PF) coils building is taking shape and is being constructed according to schedule.
The technical buildings have been elevated, the steel structure has been assembled and the roofing works have advanced. Progress has also been made in the cladding installation and mainly the concreting of the first part of a corridor floor that measures more than 9,500 m2. In parallel, the construction of the inner layers of the antirust cladding is on track together with metal sheeting and Rockwool insulation. The assembly of peripheral slabs and the realisation of the underground networks are also moving ahead.
The excavation of the Tokamak is completed, with the removal of around 200,000 m3 of rock. The construction of the lower basement is expected to kick off later this month. The entire pit has been covered by a steel safety mesh, which has been installed on the rock slopes to create a safe working environment. Three 3 tower cranes have been erected to support the assembly work of the reinforcement by delivering the steel bars. Meanwhile, the testing of the two batching plants that will produce concrete for the lower basemat and the retaining wall of the Tokamak, has been successfully conducted. As far as the geological analysis of the Tokamak pit is concerned, the cleaning process of the pit and treatment of joints have been completed.
