10. The design achieves high performance at 3x lower fluence than NIF (3  ), and meets economic goals 10 LIFE 1  beam Box 90 m 150 m Tripler output 3  = 4.3 kJ Contrast ~ 4.5% Peak, Ref ~ 1.31 Output Farfield Efficient and cost effective supply chain Offsite beamline factory Truck-shippable 1w beamline Low-overhead installation —Kinematic placement —Minimal interfaces NIF-1110-20395.ppt

11. Modular design enables very high plant availability by decoupling the laser reliability Commercial solid state laser systems ~ 10,000 hrs Modular design allows realistic performance goals for a high power system 11 NIF-1110-20395.ppt 2 hr TTR 4 hr TTR 8 hr TTR

12. The LIFE “chamber” is a network of horizontal tubes, protected by Xenon gas. It is modular and NIF scale. Modular design. Truck- shippable, factory-built Wall survival ≥ 4 years —Ions stopped in ~10cm gas —X-ray heating mitigated (to ~800C first wall) —Conventional steel for LIFE.1 Very low Tritium content —10’s g in the engine —100’s g in the separation and storage systems Very low clearing ratio (~1%) 12 NIF-1110-20395.ppt

13. The chamber system can be transported as a single unit for maintenance 13 NIF-1110-20395.ppt Vacuum chamber Fusion chamber

14. The chamber system can be transported as a single unit for maintenance 14 NIF-1110-20395.ppt Transport of ~700MT unit (cask not shown) to the hot cell

15. The chamber system can be transported as a single unit for maintenance 15 NIF-1110-20395.ppt New system installed, allowing remote maintenance / disassembly of the old unit during operations

16. … because chamber modularity results in high plant availability Calculated wall lifetime (LIFE.2) NIF-1110-20395.ppt 16

17. The design has been optimized using an integrated technology and economics model 17

18. 18 Levelized COE ($ / MWh) Cost of Carbon ($ / MT-CO 2 eq) Nicholson et al, Energy (2010) Cost of Electricity less than coal for CO 2 > $40/MT, and less than gas for > $90/MT. Could be 50% better. LIFE solar thermal coal gas

19. Outline delivery schedule, consistent with NIF experience and likely licensing timescales – meets the Primary Criteria 19 Facility design is based on a 334-element WBS, split into 50 cost centers

20. Development path 20 NIF-1110-20395.ppt Dunne - Presentation to TOFE, November, 2010 (~500 MW th )

21. Final thoughts Consideration of end-user requirements must drive IFE development Technologically, IFE success will depend on our ability to integrate interdependent sub-systems Future development must be tackled as part of a facility delivery project LIFE provides a solution consistent with 2030’s commercial delivery: —Designed to meet the Utilities’ Primary Criteria —NIF provides the at-scale physics evidence —LRU approach protects capital investment, and enables high availability —Licensing approval managed as an integral part of the process Public/private delivery partnership, and nation-wide focused effort is essential 21
