Los Alamos Hosts Predictive Science Panel
On November 12 through November 14, 2008, the Predictive Science Panel (PSP) met at Los Alamos. The PSP meets twice annually alternating between Lawrence Livermore (LLNL) and Los Alamos national laboratories to evaluate progress toward the goal of a credible predictive capability, answering the question: How do you know it’s right?
From the outbriefing on the last day of the meeting, the PSP noted “impressive progress on Roadrunner, and codes are being ported and used successfully on Roadrunner.” The PSP advocated for and laid out potential strategies for gaining fuller acceptance and support of the ASC Program with the new administration. The message is that ASC is a critical tool needed for the nation to help make decisions regarding nuclear strategies independent of the diversity and size of the stockpile. The PSP also noted good progress on W76-1 alternate materials studies.
The PSP requested that a 3-lab white paper be written on Quantification of Margins and Uncertainty (QMU) and Advanced Certification.
The PSP had a favorable response on the technical presentations delivered at the meeting. The presentations were organized into these technical categories:
- High-fidelity Simulations Enabled by ASC Tools
- ASC Tools Supporting Stockpile Decisions
- Non-Stockpile National Security Applications & ASC
