Toward less expensive conductors for the ITER magnets

Considerations on cost sensitive areas related to ITER magnet conductors such as the magnet operating conditions (heat deposition), the conductor design layout (design criteria and related margins), the conductor fabrication (material waste and achievable performance) as well as recent R and D development show that there is some potential to reduce the present ITER conductor cost. A review of the conductor requirements is used as a basis to set up an alternative design approach. (author)
