Worksite

Major progress you don't see from the air

16 Nov 2020
There was a time when aerial pictures of the ITER worksite taken at six-month intervals showed spectacular change. Buildings and structures sprouted from previously vacant lots, new levels were added to existing constructions, and progress was strikingly visible.

Today, most of the action takes place inside the buildings, where equipment is being installed, components unpacked and tools prepared for upcoming assembly tasks. Progress remains steady, but it is now rarely visible from the air.

As a consequence, playing "spot the differences" between an aerial photograph from a few days ago with one taken in late May is becoming a difficult game. Still, the differences are there. Can you spot them?

As night falls the ITER site glows red and orange. In front of the Tokamak Complex, construction materials that had been stored have been cleared to make room for three new buildings to house the power supplies for the heating neutral beam system.

A banner on the facade of the Tokamak Building celebrates a major milestone achieved in March 2020: crane access between Assembly Hall and Tokamak Building, allowing the start of machine assembly. Since then two major components have been inserted into the Tokamak pit (the cryostat base and lower cylinder) and preparations are underway in the Assembly Hall for the next in line (18 toroidal field coil supports and the cylindrical lower cryostat thermal shield).

Seventeen plant systems have to be commissioned before First Plasma, first individually and then in an integrated fashion. From electrical distribution, to control/command, cooling water, vacuum and cooling, these systems are in various stages of installation all over the platform. Five separate "balance of plant" contracts have been awarded for areas outside of the Tokamak Complex. Photo: ITER Organization/EJF Riche
