Njema Frazier

Intelligence Summary: Njema Frazier

Node Identity
Njema Frazier serves as Acting Assistant Deputy Administrator of the US National Nuclear Security Administration (NNSA) and is the current US co-chair of the US-France Stockpile Stewardship Agreement Steering Committee. In this capacity, Frazier holds the primary US institutional responsibility for managing the government-to-government collaboration framework between US weapons laboratories (LLNL, LANL, SNL) and CEA/DAM.

Strategic Relevance
Frazier's significance is as the senior US official responsible for maintaining and directing the 20+ year plasma physics collaboration between US and French nuclear weapons complexes. As NNSA's Acting Assistant Deputy Administrator, she occupies a senior position in the US nuclear weapons stockpile stewardship hierarchy, with oversight responsibilities spanning the US weapons lab complex. Her co-chair partnership with CEA/DAM's Olivier Vacus represents the current generation of leadership sustaining the institutional framework established by Delpuech and Gordon's 2002 agreement. The agreement Frazier co-chairs enables approximately 125 collaboration proposals with 20-30 active projects at any time, covering Materials in Extreme Conditions, Nuclear Physics, and Atomic and Plasma Physics. These collaborations directly enhance the physics base of nuclear weapons computer codes used by both nations. Frazier's role is particularly significant given the agreement's scope: it covers plasma physics topics including laser-plasma interactions, equation-of-state under extreme conditions, radiation transport, and atomic physics in hot plasmas — all critical for both ICF (NIF/LMJ) and weapons certification. Her position ensures continued US commitment to sharing weapons physics knowledge with France, maintaining France's status as a near-UK-level nuclear partner.

Technical Focus / Capabilities
As NNSA Acting Assistant Deputy Administrator, Frazier oversees aspects of the US nuclear weapons stockpile stewardship program, including the scientific collaboration portfolio with France. The Steering Committee she co-chairs meets annually to review collaboration progress, approve new projects, and set strategic priorities. The biennial General Meetings bring together scientists from CEA/DAM, LLNL, LANL, and SNL for technical exchanges. Frazier's scientific and managerial expertise guides the US side of collaboration project selection, ensuring that joint research benefits US stockpile stewardship while maintaining appropriate classification boundaries. The agreement covers 'unclassified fundamental science supporting stockpile stewardship' — a framework that allows extensive knowledge sharing while protecting classified weapons design information.

Network Linkage
Frazier co-chairs the US-France Stockpile Stewardship Agreement Steering Committee with Olivier Vacus (CEA/DAM Scientific Director). As NNSA Acting Assistant Deputy Administrator, she oversees the US side of collaborations with LLNL (coordinator: Jason Harke), LANL (coordinator: James Colgan), and SNL (coordinator: Thomas Mattsson). The agreement she manages was signed by John Gordon and Alain Delpuech in 2002, originating from Jacques Bouchard's 1998 initiative to send Daniel Gogny to LLNL.
