Online published on 4 December, 2023. The span of around 3.5 km which is two-third of total network of ITER cryolines and 5.2 km of ITER warmlines have been designed and manufactured in India. The cryolines for ITER has been designed to meet constraints like thermal budget of 0.25 to 1.5 W/m for 4 K lines & 2 to 7 W/m for 80 K lines and unique load cases such as insulation vacuum loss, incidental pressurization, seismic events, etc. The warmlines operates at ambient temperature, whereas few of them operate at elevated temperature during nominal operation mode. Strict manufacturing controls and conditioned manufacturing environment have played a critical role in meeting functional, safety, quality and regulatory requirements. The paper outlines the experiences and key challenges perceived during the various phases of design and manufacturing of captioned cryolines and warmlines as well as the approach towards meeting the overall requirements. The experiences gained during the design and manufacturing of cryolines and warmlines have been conducive for acquiring and accomplishing similar tasks with developed Indian resources.
