  1. Pathways to Fusion Beyond NIF Presented at: The 34th Annual Meeting and SymposiumFusion Power Associates December 10, 2013 Tom Anklam, Mike Dunne, Ed Moses Lawrence Livermore National Laboratory

  2. Key post-ignition steps on the path to commercial, inertial fusion energy • Adequate fusion gain for a power plant • Feasibility of low-cost, mass manufactured fuel • Reliable, high average power driver • Validated models for supporting technologies • Chamber physics, Tritium production, etc • Certification tests of fusion chamber structural materials • Stakeholder education and early regulatory engagement These efforts need to be done in the context of an integrated power plant design and economic modeling activity Anklam—The 34th Annual Meeting and Symposium Fusion Power Associates, December 10, 2013

  3. Systems analysis shows gain ~60 is good balance between economics and testability on NIF Cost of electricity as a fusion gain and PRF Anklam—The 34th Annual Meeting and Symposium Fusion Power Associates, December 10, 2013

  4. Low-cost, mass manufacture will require a completely different paradigm Carbon Capsules Die-cast hohlraum parts Collaboration with semi-conductor manufacturing community is proving valuable Anklam—The 34th Annual Meeting and Symposium Fusion Power Associates, December 10, 2013

  5. LLNL diode-pumped laser technology is being integrated into the “ELI Beam lines” facility in Europe HAPLS project: Delivery of a laser system for a 10 Hz, 1 Petawatt user facility, incorporating a 200 J / 10 Hz DPSSL pump laser Anklam—The 34th Annual Meeting and Symposium Fusion Power Associates, December 10, 2013

  6. HAPLS leverages many elements of the LIFE design scaled down from multi-kJ operation l/4 Rotator Diodes Diodes • Diode pumps  high efficiency • Helium cooled amps  high repetition rate with low stress • Normal amp slabs  compensated thermal birefringence, compact amp • Passive switching  performs at repetition rate • Lower output fluence  less susceptible to optical damage Anklam—The 34th Annual Meeting and Symposium Fusion Power Associates, December 10, 2013

  7. Optics durability will be key 100 Hz amplifier front-end DPSSL performance to exceed kW GOLD System under construction – giga-shot, multi-year test campaign 120 Hz, >10 J operation Low fluence design – providing a robust source to test optics underLIFE-relevant conditions Of immediate-term application to facilities such as ELI Anklam—The 34th Annual Meeting and Symposium Fusion Power Associates, December 10, 2013

  8. Technology development needs to be done in the context of an integrated plant design Capital cost areas Economic factors Capital cost Availability Reliability Maintainability Fuel/consumable costs Licensing Supply chain Environmental cost Time to market Example: laser Technology investment impact Statistical plant availability Anklam—The 34th Annual Meeting and Symposium Fusion Power Associates, December 10, 2013
