The Cleaning Facility (in white) will be the only way into the Assembly Hall for Tokamak components. The metal frame is nearly complete on the southeast end of the building, not far from the Cryostat Workshop (at far right). Significantly smaller than the Assembly Hall at 19.5 metres tall and 48 metres long, the Cleaning Facility will host the equipment for "cleaning" the ITER components prior to their entry into the pre-assembly arena.
The Cleaning Facility will also operate as an airlock between the Assembly Hall and the outside environment. In order to minimize the amount of dust entering the clean environment of the Assembly Hall, the building's two large doors will not be opened at the same time.
