FY 2015 Budget Request for Inertial Confinement Fusion

March 23, 2014

The U.S. Department of Energy has released the details of President Obama's Fiscal Year 2015 budget request to Congress for its Inertial Confinement Fusion Ignition and High Yield Campaign within its National Nuclear Security Administration (NNSA) weapons program. The details are on pages 156-173 of NNSA's overall budget request document (Volume 1) posted at:

The President would provide $513 million compared to $514 million appropriated by Congress for FY 2014.

The document states that they are pursuing three approaches to achieving the goals of ignition and high yield: Indirect Drive, Polar Direct Drive and Magnetically-Driven Implosions (MagLIF). It states, "Development of detailed physics understanding will be used to improve the designs in concert with the development of alternative ignition concepts as described in the Path Forward document submitted to Congress in December 2012". The budget request document states, "This is a discovery-driven, rather than a schedule-driven, program that will provide more opportunities for comparison with simulations and feedback to resolve the outstanding physics questions". It states, "At the end of FY 2015, progress in all three concepts will be externally reviewed to assess their progress".

The request provides support for three major facilities: the NIF at the Lawrence Livermore National Laboratory (LLNL), the Z Facility at Sandia National Laboratories (SNL), and the Omega Laser Facility at the University of Rochester's Laboratory for Laser Energetics. The request asks for $328.5 million for LLNL, $85 million for SNL (including $40 million budgeted in a separate (Science) budget category), and $63.5 million for the University of Rochester. The request would provide $9.1 million for the Joint Program in High Energy Density Laboratory Plasmas (HEDLP), an increase of $902 thousand over FY2014. The document states that increase "is consistent with strengthening academic participation" in High Energy Density physics.
