Cryostat manufacturing

The week the workshop emptied

For a few minutes, the Cryostat Workshop resounded with Beethoven's "Ode to Joy." It was a strange moment, both solemn and poignant. Before long, the self-propelled trailer transporting the base section of the ITER cryostat began to move towards the mega-door facing the Assembly Hall and, soon, the vast hall that had teemed with activity for almost five years stood empty and silent. It will remain so until the segments of the fourth and final section of the cryostat (the top lid) are delivered in July to be assembled and welded.

On April 15, the cocooned cryostat upper cylinder was moved out of its birthplace to be placed in temporary storage. One year earlier to the day its near-twin, the lower cylinder, had followed the same route. (Click to view larger version...)
On April 15, the cocooned cryostat upper cylinder was moved out of its birthplace to be placed in temporary storage. One year earlier to the day its near-twin, the lower cylinder, had followed the same route.
Two days before, on Wednesday 15 April, the upper cylinder had made a similar exit, but instead of being delivered to the Assembly Hall, it was moved to a dedicated storage area to be positioned next to its near-twin, the lower cylinder.

Watching these two huge components slowly crawl out of their birthplace gave a sense of the exceptional dimensions of the ITER Tokamak. It also signalled just how close ITER is to the beginning of the assembly phase.

Watching the cryostat base section entering the antechamber of the Assembly Hall gave a sense of the exceptional dimensions of the ITER Tokamak. (Click to view larger version...)
Watching the cryostat base section entering the antechamber of the Assembly Hall gave a sense of the exceptional dimensions of the ITER Tokamak.
Once inside the Assembly Hall, directly underneath the beams of the overhead crane, the 1,250-tonne base section appeared ready to undertake the 170-metre-long journey to the mouth of the Tokamak pit.

The ITER cryostat—the largest stainless steel high-vacuum pressure chamber ever built (16,000 m³)—will provide a high vacuum, ultra-cool environment for the ITER vacuum vessel and superconducting magnets. The Indian Domestic Agency has collaborated with main contractor Larsen & Toubro Heavy Engineering (manufacturing design, segment fabrication in India and assembly at ITER); MAN Energy Solutions, Germany (Larsen & Toubro sub-contractor for on-site welding); and SPIE Batignolles TPCI, France (Larsen & Toubro sub-contractor for the realization of the Cryostat Workshop) to deliver the components to specification and on time.
