Dr. Chris Deeney, Assistant Deputy Administrator for Stockpile Stewardship Office of Stockpile Stewardship, NA-11 December 16, 2010

2. 2 NNSA Program Management Assessment of Ignition  Great progress is being made on NIF  JASON appropriately highlighted the technical challenge  Layered capsule implosions are underway  The present execution plan will have D-T experimental studies in early FY12  Other ICF concepts are also making progress  Direct drive at Omega and Polar drive on NIF have produced excellent results  Pulsed Power has made progress with various Direct drive and Indirect drive designs NIF Omega Laser Facility Z Pulsed Power

3. 3 Future ICF Strategy  Post-NIC, delivery to the Stockpile Stewardship Program, including uses of ignition will be a focus  We plan to maintain all our HEDP premier facilities as well as intermediate scale laser and pulsed power facilities  We will maintain an investment in next generation / advanced fusion concepts  Shock- and fast-ignition, indirect drive with green, direct-drive, and pulsed-power fusion can be studied to achieve higher outputs and gain  There will be balanced but smaller investments compared to the drive for ignition and the balance and level of investment will be informed by stewardship experimental needs

4. 4 Benefits to NNSA of an IFE Program  Intellectual vitality  Parallels the goals of our academic alliance program  Challenges science, technology and engineering at the laboratories  System solutions with multidisciplinary science, technology and engineering is what we do  Technology benefits  Investments in ignition concepts  Radiation hardness and materials in extreme environments are synergistic with many missions  Capsule and driver technologies will improve our facilities and/or reduce costs for future facilities

5. 5 Opinions / Questions/Guidance needed from this panel  The NNSA ICF program management believes and demands technical competition in ICF and would want this in a future IFE program – is this true?  The IFE program should start broadly then focus over time  Questions  How broadly?  How long to technology down select?  How to maintain a back-up concept after down select?  Driver technologies are probably equally important to other issues  What other challenges are important (targets, first wall materials, tritium breeding, servicing and other operational issus)?  Which can the Government invest in to get broad benefit, especially for energy missions?  What metrics (hopefully feasibility and economics driven) can be used to inform downselects in the future?
