Design and structural analysis of ITER thermal shield under transportation environment

Thermal Shield (TS) in ITER tokamak reduces heat loads from vacuum vessel and cryostat to superconducting magnet structure. Unlike to other components in ITER tokamak, most of TS have slender structure with panel thickness of 20 mm. Due to its structural uniqueness, TS cannot be secured on packing box directly since forces caused by lashing ropes may induce undesirable deformation and structural damage during transportation environment. Therefore, transportation jigs are required to support and fasten TS. In this study, structural design and safety assessment of TS transportation jigs are presented.
