Completion and Factory Acceptance Test of the ITER PF1 Coil

In the International Tokamak Experimental Reactor (ITER), six Poloidal Field (PF) ring coils are employed to initiate, stabilize, and shape the plasma. The Russian Domestic Agency for ITER is responsible for the supply of the PF1 Coil. The manufacturing process, which includes design, tooling procurement, building preparation, and component qualification, spanned over 10 years and concluded in 2022. This article primarily focuses on the final assembly activities following the vacuum pressure impregnation of the coil's winding pack, with specific emphasis on risk mitigation measures to prevent the failure of the coil's electrical insulation and instrumentation. Further, the factory acceptance tests of the completed coil and their outcomes are described and discussed in comparison with the established requirements. These tests include measuring the electrical insulation performance under partial vacuum conditions, checking for leak tightness of the pressurized hydraulic circuit, and conducting dimensional inspections of the coil's interfaces critical for integration into the ITER tokamak. Finally, the article addresses the transportation of the coil and the upcoming cold test to be conducted at the ITER site.
