What is PSAAP?
  • Predictive Science Academic Alliance Program
  • Primary Goal: is to establish validated, large‐scale, multi‐disciplinary, simulation‐based “Predictive Science” as a major academic, applied research program
  • Predictive Science:  Application of verified and validated computational simulations to predict properties and dynamics of complex systems
  • Collaborations with universities involve training, recruiting, and working with top researchers in key disciplines required by stockpile stewardship
  • Engage U.S. academic community in making significant advances in predictive modeling and simulation technologies
