Fusion in the NNSA Donald L. Cook Deputy Administrator for Defense Programs National Nuclear Security Administration Fusion Power Associates Annual Meeting December 1-2, 2010 Washington, DC
Defense Programs supports science as a foundation for national security • Through scientific pre-eminence the U.S. has maintained the nuclear deterrent for 20 years without testing. • Science underpins our nuclear security and enables policy and treaty decisions. • I have elevated science within Defense Programs (NA-11) • Strengthens and recognizes key role. • A new science council has been formed to advise on critical decisions. Science is more essential for our prosperity, our security, our health, our environment, and our quality of life than it has ever been before. -- President Obama at the National Academy of Science

Three major DOE missions rely on High Energy Density Laboratory Plasmas (HEDLP) for success • National Security • Stockpile Stewardship • Protecting against technological surprise • Fundamental Science • Stewardship of HED • Cross-cut with materials science mission • Energy • Inertial Fusion Energy Sciences energy-related HED
Primary phase Super-critical assembly Primary energy production Energy transfer X-rays transfer energy from primary to secondary HE phase High explosive creates supercritical assembly Secondary phase Secondary produces energy, explosion and radiation Nuclear Phase (UGTs NIF and, Z) Pre-nuclear phase (UGTs, sub-crits, DARHT, JASPER, etc) After the explosive phase, weapons rapidly evolve into the HED and plasma regimes Weapons operation proceeds through the conditions of planetary interiors, to stellar interiors
NNSA mission needs have driven the creation of HEDP environments that are ideal for the study of complex HED plasmas and materials Astrophysical and planetary science applications High Mach Number unstable flows Jets Rayleigh Taylor Instabilities Materials in the Extreme HED laboratory experiments MHD, thermo-electric, and “anomalous” heating Mass Outflow Shocks and radiation transport
The ICF Program has created an extraordinary array of facilities for HED research • National Ignition Facility (NIF) • Only access to burning plasma conditions • Important mission experiments have already been performed • Omega EP • Sophisticated high irradiance capabilities • Important venue for advanced fusion research • Z Machine • Key venue for weapons materials science measurements • Outstanding new results at 4 Mbar. • Enormous increase in computational power
High energy lasers and the Z Machine have been used to extend solid state physics to the 10 Mbar regime Ramp compression shows diamond is stable and strong to 8Mbar Ramp laser intensity to produce shockless compression 8 New cold-solid-state ramp compressed data Pressure (Mbar) 4 Calculated Cold curve Diamond cell data 0 4 5 6 Density (g/cc) • Edwards, et al. (PRL 04) • Smith, et al. (PRL 06) • Bradley, et al. (PRL 08) • Eggert et al. (SCCM 07) Bradley et al NIF designs use the same technique to study solids to many >30 Mbar
The National Ignition Facility is poised to make extraordinary contributions Science, 327, 1228, Glenzer et al A first THD shot was conducted in September.
The achievement of igniting conditions will open new frontiers in plasma research • Plasma temperatures > 20 keV ; compressed densities > 1000 gm / cm2 ;pressures ~ 1 Tbar • The high performance implosions needed for ignition can also be employed in a variety of non-ignition basic science investigations. • Planetary and astro- physics • Materials under extreme conditions • Performing detailed measurements under igniting conditions will present a considerable diagnostic challenge.
NNSA relies on intermediate scale plasma science facilities for basic science support • Examples of intermediate size plasma facilities: • Jupiter at LLNL (lasers): support of NIC and NIF; mission; users • Trident at LANL (laser): support of NIF and NIC; mission; users • Texas Petawatt at UTX (laser): discovery-driven research; users • Z-Beamlet / Z Petawatt at SNL (laser): diagnostic for ZR; users • Nevada Terawatt at UNR: pulsed power Intermediate-size plasma facilities provide both direct and indirect mission support, and we are encouraging user access at our intermediate facilities
A portion of time at NNSA Facilities will be devoted to basic science investigations • The NNSA encourages the exploitation of its HEDP facilities by the academic scientific community. • NNSA will provide resources to establish user programs and dedicate a fraction of the shots to fundamental science experiments. • Open proposal and peer review processes will be employed. • NNSA strongly encourages technical competition
As the head of Defense Programs, I will expect technical competition in the HEDP Program – this looks like … • Multiple approaches to solving the major challenges to ensure creativity, peer review and successful completion • Breadth in the community – the best in laboratories, industry, and academia working together • Outside engagement and applying our tools, methods and scientists to other challenging science issues • Teaming with the Office of Science and peer reviewed competition where appropriate • Support for and access to a range of different technologies and facility scale (intermediate to NIF) Deuterium EOS is a poster child for how technical competition benefits our program.
NNSA collaborates with the DOE Office of Science in encouraging HED basic science • NNSA is committed to providing the required resources to NIF, Z and Omega each year both to establish user programs on these facilities and to dedicate a fraction of the shots on each facility for experiments on fundamental science proposed and led by members of the academic community. The selection of those experiments will proceed through an open, transparent proposal and peer review process similar to that employed at Office of Science facilities. We hope that you will encourage your scientific communities to investigate this opportunity

Inertial Fusion Energy- a snapshot in 2010 • Fusion Energy – no carbon dioxide, modest nuclear waste, • 50 years of exploration – ignition at NIF will be key • NAS to provide recommendations on IFE priorities • Timeline and demonstration potentially similar to ITER
Inertial Fusion Energy 2010Principles applied by Working Group • Focus on IFE specific program that relies on ICF and FES but does not replace them • Look at fastest route to demonstrate most critical elements • Rapid repeated ignition (once per second for hours) • Using technology applicable for steady and affordable energy source • Flexible management and budget with risks • Driver technology and specific ignition approach identified as critical components • 5 years to down select, • Use existing facilities including NIF
HEDP is one of the core disciplines of stewardship science Scientific Challenge Incredible Tools HEDP research allows us to validate our models in environments that remove the need for nuclear testing - the level of challenge requires technical competition
Department of Energy and other agencies have defined major challenges for the field of high energy density physics
High Energy Density Physics is a key discipline underpinning Stockpile Stewardship • Extreme conditions in temperature, density, pressure allow investigation of a large span of physical states. • These extreme conditions are required to meet national security needs but also enable contributions to a broad span of basics physics including astrophysics, materials in extreme conditions and many other sub-disciplines. • Stewardship of HED and plasma science provides essential support for the NNSA mission.
