ITER is planned to be the first fusion experiment operating under reactor-relevant plasma conditions integrated with key technologies in a regulatory licensed environment. The ITER design, safety analysis and cost estimates are supported by the physics basis, analyses and technology R&D. Full-sized or scalable modules of key components have been successfully manufactured and tested. The scientific and technological bases to start ITER construction are established. Inter-governmental negotiations to prepare the Joint Implementation Agreement for ITER construction and operation are expected to conclude in 2003. ITER operation would then be able to start in 2013.
