2nd vacuum vessel sector from Korea
The nine 40-degree sectors required to form the ITER toroidal chamber are largely similar, differing only in the details relevant to their position in the circular arrangement and interfacing components.
Like its predecessor, sector #1(7) will go through a series of operations in the Assembly Hall, such as the installation of diagnostics and instrumentation, before it is upended and moved to the sub-assembly tooling to form the second of the ITER Tokamak sub-assemblies.
* Readers will have seen this sector referred to as #7 in past articles. In fact, sectors #1 and #7 (both supplied by Korea) are nearly identical. It was decided to install Korea's second sector (#1) in the place of #7 in the assembly pit at ITER—hence the name "#1(7)"—in order to accelerate the assembly of the torus chamber. The sectors in positions #6 and #7 in the assembly pit will be the first of nine to be welded together.
