ITER Assembly Opportunities

a wide variety of opportunities exist for the pro-active supplier

� enabling activities (assembly simulation, planning, procedures, assembly mock-ups, qualifications)

� Main Assembly Contract (IO contract)

� support to IO-MAC activities (e.g. custom machining)

� specialist services (e.g. metrology, NDT, transport)

� independent installation contracts (IO or DA contract)

� supply of assembly facilities and standard tools (IO contract)
