1 1 by Dr. John Parmentola Senior Vice President Energy and Advanced Concepts Presented at the American Security Project Fusion Event June 5, 2012 The Path to Net Electricity for Magnetic Fusion

2 DEMO ITER Worldwide Research Has Advanced Fusion to the Goal of Sustained Ignition Many orders of magnitude (a factor of one trillion) improvement have been achieved over 40 years Significant fusion power (> 10 MW) already demonstrated ITER will demonstrate a 500 MW sustained fusion plasma

3 U.S. Domestic Program Provides Powerful Capabilities to Address Key ITER Issues ¼ scale prototype of ITER Can reproduce ITER operating regimes Extensive diagnostics ITER-level magnetic field Reactor relevant metal wall Reactor-like power density Develop physics solutions critical to ITER success Establish more robust performance scaling trends Provide a fuller physics picture through complementary measurement techniques Together: Extreme plasma shaping Large fraction of energetic particles High ratio of thermal to magnetic pressure

4 Power Plant ITER U.S. Path to Net Electricity Requires Talented People and a New Facility FNSF DIII- D Fusion Nuclear Science Facility (FNSF) challenges: - High performance, steady-state operation - Makes its own fuel - Materials for extreme environments A gifted and talented workforce is required to support & exploit ITER

5 1 ITER Site Construction Progresses PF Coil Winding Building Concrete Work for Tokamak Complex PF Coil Spreader Beam Concrete Walls & Anti-Seismic Pit

6 Plan to Net Electricity Success in ITER and FNSF would enable DEMO construction to begin in next decade!

7 Summary U.S. investment over 40 years has led the world in realizing fusion energy ITER, the largest experiment in human history involving 6 nations (US, China, India, S. Korea, Japan and Russia) and the EU, is the next major step U.S. domestic program is essential in realizing the success of ITER and fusion energy in the next decade
