Progress on the manufacturing of ITER thermal shields

•Manufacturing of the LCTS (Lower Cryostat Thermal Shield) cylinder and the VVTS (Vacuum Vessel Thermal Shield) sector #6 was completed.•Leak tightness of the TS cooling tubes is guaranteed by the test and inspection. Inner surfaces of the cooling tube are inspected visually using the special endoscope and the leak tightness has been qualified by the pressure and helium leak test.•The on-site installation feasibilities of the TS are validated by the preassembly test performed at the factory. TS panels are well assembled by bolting and additional machining of the bolt holes are not required.•According to the qualified coating process, the TS panels are electro-plated with silver. The measured emissivity met the requirement.
