One of the first things that ITER Council delegates will notice when they meet on Wednesday 15 June, in person for the first time in two years, is how the view from the corridor along the Council chamber has changed. The floor-to-ceiling windows, which used to frame a spectacular view of the heat rejection system's cooling towers, now highlight the future "brain" of the ITER installation—a 3,500-square-metre, three-storey
ITER's brain centre—the Control Building—should be completed by the end of the year. Operators will have direct access to the building from Headquarters, by taking the overpass visible on the left side of the image.
For the ITER staff and contractors who happen to have an office facing in the same direction, change has been more progressive. For the moment, the works involved in the construction of the two buildings that will host the neutral beam power supply have been performed mostly underground. But on what used to be a large empty lot in front of the Tokamak Complex, structures are now beginning to appear. Ultimately, the familiar view of the crane hall's north facade will be partly hidden by the two buildings—one of them 25 metres tall.
From the roof of ITER Headquarters, the Tokamak Complex stands out as the major feature of the ITER construction site. After a pause while European construction teams concentrated on delivering the Tokamak Building crane gallery (centre), work is proceeding at level L4 of the Tritium Building (located to the left of the Tokamak Building). On the right side of the Complex, behind the red crane, infrastructure for neutral beam power supply is emerging.
Over the past few years, as the Tokamak Building crane hall was
The Tritium Building will accommodate the different systems and equipment that store, handle and recycle tritium fusion fuel. Most of the functions of the Tritium Building are directly linked to the full-power operation of the ITER Tokamak and, as such, will not be needed before 2035. However, the building also accommodates equipment that must be operational for First Plasma, such as the gas injection system that will feed hydrogen to the vacuum vessel, or components that are part of the HVAC, cooling system, or vacuum pumping systems. It is scheduled for completion in one year.
