ITER prototype divertor cassette fabrication, integration and final assembly

This paper reviews fabrication and assembly of the prototype ITER divertor cassette. It discusses component manufacturing, integration management, and final assembly operations on this large, 7.5-ton part. Producibility and modularity were key design drivers for the ITER divertor hardware since it must be affordable yet satisfy demanding performance and remote maintenance requirements. Critical fabrication and integration issues that were addressed in producing the prototype hardware are discussed.
