## Things on our minds today

- Hill Staff changes
- Transition soon
- New NPR
- DP Leadership changes
- UQ
- SNL SCIF
- Out year pressures
- RRW   ?
- Fewer codes
- Mission
- DSB

***The ASC booth, “Predict with Confidence,” introduced interested constituents, congressional staffers and members of Congress to some of NNSA’s most high-tech simulation tools used in Stockpile Stewardship.**** *

- The Congressional Modeling and Simulation Caucus (Randy Forbes, R-Va, Chair).

## Focus Area 4

- A vision for NNSA as the technology arm for agencies with national security responsibilities.
- Achieved through joint sponsorship agreements with DOE landlord oversight.
- Communicate vision internally and externally, work with Congress and other agencies to develop sponsorships and support.
- Provide enhanced security to the US and its allies and preserve the Defense Program labs as national assets.

## Focus Area 4 Status Update:  NNSA and its Labs Mission and Vision

- Phase 1: White Paper
- Two NNSA/Director Meetings held in DC (June and September)
- Working group developed
- Joint White Paper written
- Signed by four Directors, NNSA Administrator and Under Secretary for Science reflecting consensus on enhanced mission.
- Language for broader mission/vision incorporated in FY09 Budget Request
- Phase 2: Implementation
- Third Director meeting held in DC in January
- Near term opportunities for partnering with other agencies being considered
- Entering into discussions with labs and sites on funding mechanisms, Reducing costs,...
- Pilot projects being identified for FY08 development
- FY10 NNSA guidance being drafted to reflect mission/vision white paper

## FY08 Reports to Congress

**FY08 Omnibus Appropriations Conference Report**
*“**The NNSA is directed to develop a**** long-term scientific capability roadmap**** for the national laboratories to be submitted to the Committees on Appropriations”*
**ENERGY AND WATER APPROPRIATIONS BILL, 2008**
**REPORT  110–127 (p.151)**
*“**The Committee directs the Department to provide a ****comprehensive computing proposal**** that involves the input from the weapons laboratories that includes a long term strategy to maintain the necessary simulation capabilities within the complex and to drive innovation and competition for technology and performance.”*
*“**The Committee is also frustrated with the lack of scientific development vision for the labs. The NNSA has focused on its transformational plan, based on the RRW systems, but appears to have given little thought to the scientific path forward. The Committee directs the Department, drawing on the resources within NNSA and the Office of Science, to provide to the Committee a ****research and development plan**** that addresses unresolved physics and materials questions that will support national security mission as well as contributed to improving our energy independence, non- proliferation mission and to support biomedical applications. This plan should explore technology options that can be deployed and provide an added capability to our R&D program to update the scientific capabilities at each of the laboratories.”*

## Looking Ahead

- Leadership in national security computational science remains a priority
- Helping shape our future this year
**Injecting ST&E more strongly into certification and the production complex**
**Predictivity **

## ASC FY2009

**Priorities **
**Increasing our current capability as the computational surrogate for nuclear testing & weapons behavior – moving towards predictivity**
**Application of mature ASC tools to nuclear security issues related to certification, as well as nonproliferation, attribution/forensics, and emergency response**
**Engaging other government agencies to apply the ASC capabilities and resources – codes, workforce and facilities – beyond the historic nuclear weapons core mission and include the full spectrum of national security interests**
**Using NNSA and ASC program guidance to ensure future balance and sustainability for the ASC program**
**Projected Achievements**
**Implement physics-based representation of energy balance in the weapons codes**
**Validate a suite of physics-based models and high-fidelity databases supporting the full operating capability of the DTRA National Technical Nuclear Forensics program**
**Perform simulations on Roadrunner that will inform boost physics models in weapons simulations**
**Quantify numerical uncertainties using the Sequoia initial delivery system in preparation for high fidelity UQ studies on the final system**
**Continued support of the Thermonuclear Burn Initiative (TBI) – the 2007 through 2012 ‘moon shot’ to understand a leading source of uncertainty**
