Stewardship Science Academic Alliances

The Stewardship Science Academic Alliances (SSAA) Program supports scientific academic research programs to develop the next generation of highly trained technical workers able to support its core mission and to ensure there is a strong community of technical peers, external to the NNSA national laboratories, capable of providing peer review and scientific competition to strengthen the basic fields of research relevant to the national security enterprise (NSE).

The Stewardship Science Academic Alliances (SSAA) Program funds both collaborative Centers of Excellence and smaller individual investigator research projects to conduct fundamental science and technology research of relevance to stockpile stewardship. Current technical areas include studies of materials under extreme conditions, low-energy nuclear science, high energy density physics, and radiochemistry. SSAA funding supports research at approximately 80 universities, including training of over 350 undergraduate students, graduate students, and post-doctoral researchers each year. A key element of both centers of excellence and individual investigator awards is the connection of students with the nuclear security enterprise. These opportunities are focused in technical fields critical to stewardship science, building a field of talented researchers and committed doctoral students sharing a common desire to advance science while impacting national security.
