3. Other Frameworks Note : IEA FPCC recommends coordination among various frameworks - 2 - [2] IAEA framework : IAEA technical meeting on 1st generation of fusion power plants [1] IEA framework : International Energy Agency Cooperative Agreement on Environmental, Safety, and Economic Aspects of Fusion Power

4. Roadmap to Fusion DEMO 2010 2015 2020 2025 2035 Decomi ssioning Construction Development of breeding blanket Fusion material development (inc. IFMIF) Achieve Q=20, 400s Achieve Q~5 steady-state operation Proof of principle of breeding blanket Confirm physics database Confirm material database DEMO physics input for starting EDA construction power production Grid connection licencing 2005 FY ITER program Satelite Tokamaks And other devices Fusion technology development DEMO Basic performance phase Decision of construction JT-60 and JET 2030 Performance extension phase Test of breeding blanket Coordination of DEMO physics and tech. R&D CDA-like EDA/R&D Concept exploration - 3 - JA,US,EU road map is similar targeting power production early 2030
