Progress in Design, Analysis, and Manufacturing Studies of the ITER Feeders

Abstract

The feeder design has been improved by the feeder teams at the ITER Organization (IO) and the Institute of Plasma Physics, Chinese Academy of Science (ASIPP) by incorporating the results of mechanical and thermal analyses as well as the system integration and assembly tolerances in the present CAD model. The feeder design is being finalized progressively, and will be delivered to the Chinese Domestic Agent (CNDA) for further procurement arrangement (PA) activities. Pre-PA manufacturing studies and tests performed at ASIPP have been effective in clarifying feeder design feasibility and component manufacturability. This paper reports the recent advancements on feeder design, analysis and manufacturing studies.

Correction coil and magnet feeder lessons learned

“…as shown in figure 1(b), to convey electrical power and cryogenic coolant to the superconducting magnets. All magnet feeders are made of three main segments with coil terminal box (CTB), cryostat feedthrough (CTF) and in-cryostat feeder (ICF) [1][2][3][4].…”

Preliminary design of the cold mass supports for the EU DEMO feeders

“…Difficulties in the design of the CMSs arise from the several clashing requirements that these structural elements must fulfil, i.e. [6][7]:…”

Simulations of Twin-Box Joints for ITER PF Coils

“…With the two-in-hand winding pattern, each DP has a joint connecting two cable lengths. The other joints interconnect the DPs and connect the coil terminals with the feeder lines [4]. The joints are located on the outer radius of the coil to keep them away from the high magnetic field.…”
