Historical Background of ASC

FY1994: The President and Congress established the DOE Stockpile Stewardship Program to meet the challenge of maintaining our nuclear deterrent under a comprehensive test ban.

FY1996: The ASCI program was established and funded to “promptly shift from nuclear test‐based methods to computational‐based methods”

FY2004: ASCI transitioned to ASC with a vision to “Predict with confidence the behavior of nuclear weapons through comprehensive science‐based simulations.”

ASC uses simulation and computing to maintain the U.S. nuclear deterrent

Central Problem: Replacement of underground testing with a rigorous scientific methodology with which to assess and maintain our confidence in our nuclear stockpile.

Time Urgencies: Supporting national policy with respect to the maintenance of our nuclear stockpile requires that we be able to certify annually to the Secretaries of the Departments of Energy and Defense that the stockpile is safe, reliable, and secure.

ASC provides a national program planned and coordinated across the three Defense Program Laboratories with partnerships with other federal agencies, academia, and industry.

ASC simulations have three dominant drivers

Supporting the weapons program via predictions with quantified uncertainties– Design change certification (i.e. Life Extension Program)– Annual assessment– Significant findings investigations, manufacturing, etc.– Performance, safety & surety– Weapon system response, and survivability, under potential environments

Reducing uncertainty through understanding and discovery– Removing the simulation unknowns & understanding Aging– Improving the material property databases & physics models representing reality

Meeting broader national security missions– Secure Transportation– Nuclear Forensics– Emergency Response– Defense Nuclear Security and Vulnerability

What is PSAAP?

Predictive Science Academic Alliance Program

Primary Goal: 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

PSAAP III Procurement

ASC is in the process of scoping out the new program ASC will be seeking interested proposers’ inputs via upcoming Request for Input (RFI)

Timeline (subject to change)– RFI issuance – end of April 2018– RFP issuance – early 2019– Proposal Evaluation & Site Reviews – summer 2019– Selection of Awardees – end of 2019– New PSAAP III Centers – mid April 2020

14


Rules of Engagement

• Prior to Release of RFI:– Proposers are allowed to contact NNSA ASC lab experts to ask questions

– Word of Caution: View the lab experts’ responses or comments as such; not representative of HQ or the program or “what to propose”

– Proposers will be evaluated entirely on their own team’s merits, not any labs’ nor non‐academic collaborators’

• There should be no discussion between ASC and any person or organization interested in PSAAP III with respect to this procurement between the release of the RFI and the announcement of the results of the RFI.• NOTE: Doesn’t preclude ongoing research (non‐PSAAP III related)

• There should be no discussion between ASC and any person or organization interested in PSAAP III with respect to this procurement between the release of the RFP and the announcement of the final decisions of the RFP.
