ITER's First Plasma is scheduled for December 2025.
That will be the first time the machine is powered on, and the first act of ITER's multi-decade operational program.
On a cleared, 42-hectare site in the south of France, building has been underway since 2010. The central Tokamak Building was handed over to the ITER Organization in March 2020 for the start of machine assembly. The first major event of this new phase was the installation of the 1,250-tonne cryostat base in May 2020. In the ITER offices around the world, the exact sequence of assembly events has been carefully orchestrated and coordinated.
The successful integration and assembly of over one million components (ten million parts), built in the ITER Members' factories around
the world and delivered to the ITER site constitutes a tremendous logistics and engineering challenge. The ITER Organization will be carrying out the work supported by a number of assembly contractors (nine contracts in all).
In November 2017, the project passed the halfway mark to First Plasma. (More here.) In July 2020, the project officially launched the machine assembly phase. (More here.) Today, project execution to First Plasma stands at 70.5 percent (July 2020 data).

Throughout the ITER construction phase, the Council will closely monitor the performance of the ITER Organization and the Domestic Agencies through a series of high-level project milestones. See the Milestones page for a series of incremental milestones on the way to First Plasma.
See these pages on the ITER web for more information on ITER construction and assembly.
