Development of Insulation Manufacturing Design and Techniques in ITER TF Coil Manufacturing

Year: 2025

Type: article

Abstract: The National Institutes for Quantum Science and Technology （QST） have completed the manufacturing of nine ITER TF coils. In TF coil manufacturing technologies, insulation is one of the most critical techniques because insulation failure can directly lead to TF coil scrapping. Therefore, QST developed insulation techniques via trials and with the cooperation of manufacturers. In addition, COVID-19 has influenced impregnation work in WPs and coil case assemblies. Alternative resins with especially low viscosity were developed to overcome this difficulty. Finally, based on the experience of TF coil insulation, insulation failure in JT-60SA superconducting coils was repaired. As a result, the first plasma was achieved in October 2023.
