19 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) 19 Assembly Workshop Robert Shaw
