Punctuating the inner surface of the vacuum vessel are many strategically placed windows that will be used by diagnostic systems to 'observe' the plasma. " [...]
Main buildings | Under, over and beside the Tokamak
In the immediate vicinity of the machine—in the deep vaults of the Tokamak Complex or under the high rafters of the Assembly Building—construction teams are preparing for 2019 assembly-related activities. Whether it is receiving and handling the first major components or beginning to install the first structural supports for system components in the concrete buildings, the coming year will mark the transition on site between a heavy focus on construction, to the management of construction and machine and plant system assembly activities in parallel.
Now painted in white, the lowest basement level of the Diagnostic Building is ready for handover to contractors for the beginning of systems installation. Embedded plates—for the attachment of system supports—are visible on all surfaces.
Under the financial and oversight responsibility of the European Domestic Agency civil construction works on site are progressing, and are soon to pass the 70 percent completion mark.
As buildings are completed, the ITER Organization has the overall responsibility for the integration and assembly of components delivered to the ITER site by the seven Domestic Agencies. The actual work of the assembly phase will be carried out primarily by ITER Organization contractors (or, for some plant assembly works, by Domestic Agency contractors). Work will be tendered out in nine main contracts.
In the build-up to full-scale assembly, which begins with overhead crane access to the Tokamak Building in March 2020, components are arriving on site with increasing frequency. In 2019 a number of major arrivals are planned, including the first toroidal field coil, the first vacuum vessel sector, assembly tooling, and the first thermal shield segments. Installation activities will start in the lower levels of the Tokamak Complex while in the Assembly Hall, the first specialized assembly tools will be moving into action.
