About this program

The Department of Energy's National Nuclear Security Administration (NNSA), through its Office of Defense Programs, funds research under the Stewardship Science Grant Program (CFDA 81.112) in support of the Stockpile Stewardship Program, with the most recent grant award disbursed on September 1, 2026.

The program funds fundamental science and technology research at U.S. academic institutions in areas directly relevant to nuclear weapons stockpile stewardship. Recent awards support experimental investigation of materials under extreme conditions (pressure, temperature, magnetic fields), low-energy nuclear science including neutron capture cross-section measurements and fission studies, radiochemistry work with actinides and plutonium, high-energy-density physics and inertial confinement fusion, additive manufacturing of materials for extreme environments, and instrumentation development for dynamic compression and X-ray diagnostics. Work emphasizes training graduate students and early-career scientists to build a workforce pipeline to NNSA laboratories.

The program portfolio comprises 594 awards since 1997, obligating $2.23 billion in federal dollars. Award activity has been volatile recently—26 awards in 2025, 3 in 2024, 10 in 2023, and 38 in 2022—and only 2 awards have been obligated so far in 2026. Funding is nearly evenly split between the Department of Energy (364 awards, $676.5 million) and NNSA (230 awards, $1.56 billion). The portfolio is predominantly Project Grants (513 awards, 86 percent) with smaller shares of Cooperative Agreements (70 awards, 12 percent), Block Grants (9 awards, 2 percent), and Formula Grants (2 awards, less than 1 percent). Project grants typically range from $300 thousand to $750 thousand; cooperative agreements for centers of excellence reach multi-million-dollar scale, with recent examples including $305.3 million for the University of Rochester Laboratory for Laser Energetics (awarded October 2023), $14.9 million for the Stewardship Science Graduate Fellowship/Laboratory Residency Graduate Fellowship program management (September 2025), and $10.5 million for dynamic compression science at Argonne (March 2025).

Recent project-grant awards span materials physics, nuclear data, and advanced diagnostics. Michigan State University received $600 thousand for nuclear fission modeling using density functional theory (June 2025); University of Notre Dame received $600 thousand for plutonium and americium target synthesis using solution combustion methods (June 2025); and multiple recipients received $600 thousand each for cross-section measurements on tungsten, correlated neutron-gamma data analysis, and characterization of cerium particle reactions (all June 2025).

One open grant opportunity is currently posted: High-Energy-Density Laboratory Plasma Science (DE-FOA-0003526), due March 27, 2025, jointly sponsored by the DOE Office of Science and NNSA, unrestricted to applicant type. The Stewardship Science Academic Alliances Program opportunity (DE-FOA-0003242) closed June 20, 2024 and is not currently open; proposals for renewal should be submitted to the next open announcement. Eligibility varies by solicitation—some rounds restrict applications to institutions of higher education; others include nonprofits and for-profit organizations. Generally, grants are approved for two- to three-year project periods and funded annually; cooperative agreements typically carry five-year project periods.

Objective and description

Objective

(1) To grow the U.S. scientific community through university involvement in areas of fundamental science and technology relevant to stockpile stewardship; (2) to promote and sustain scientific interactions between the academic community and scientist

Description

The Nation's nuclear weapons stockpile is a vital part of our national security infrastructure. Ensuring that this deterrent is second to none requires the best science and technology. Having top tier scientists and engineers in the areas critical to stockpile stewardship is the only way to ensure the best science and technology. The National Nuclear Security Administration (NNSA) supports this effort through the Office of Defense Programs.

Eligibility

Applicant eligibility

Some solicitations are open to institutions of higher education only and others include nonprofit organizations and for profit commercial organizations. See individual funding opportunity announcements for details on eligibility.

Beneficiary eligibility

Depending upon the eligibility requirements of the individual solicitation, U.S. public and private institutions of higher education and/or nonprofit organizations and for profit commercial organizations will benefit. The Federal government will also benefit from the research of these grants.

Uses of assistance

Financial support in whole or in part may be provided for such purposes as the salaries, materials and supplies, equipment, travel, publication costs, training costs, and services required for conducting research, training, related activities, and advanced technology projects or assessments. Funding is provided for basic and applied research in the field of physical science in support of the DOE stockpile stewardship program. Restrictions on use of funds depend on grant provisions. Funding is provided for the purpose of exploring an idea that does not unnecessarily duplicate work already in progress or contemplated by DOE, is not already known to DOE, or has previously unrecognized merit.

Length and time phasing of assistance

Generally, grants are approved for two-year or three-year project periods and funded one year at a time. Depending upon specific circumstances, grant project periods may range from one year to five years, at the discretion of the program office. Cooperative Agreements typically have five-year project periods and are funded one year at a time.

How to apply

Criteria for selecting proposals

(1) Alignment with the areas of technical scope; (2) Scientific/technical merit of the project, including innovativeness and originality; (3) Expected impact on the area of technical scope addressed; (4) Consistency with the objective of this academic alliances program to focus on advanced experimental investigations; (5) Qualifications of the Applicant's personnel and adequacy of proposed resources; (6) Feasibility of plans for carrying out the proposed research, considering such factors as: appropriateness of the technical method and approach, facility compatibility, other commitments, competition and timing; (7) For projects currently receiving funding under this program, the scientific impact of recent results and accomplishments; (8) Level of interaction with NNSA/DP laboratory personnel and the potential to train students in scientific areas defined by the technical scope in order to build a long-term recruiting pool for the NNSA/DP laboratory complex. Generally, a higher degree of interaction both quantitatively and qualitatively is considered desirable; (9) Leverage provided by cost sharing with other funding sources.

Award procedure

Applications will receive an administrative screening to determine if they are complete and in compliance with the terms of the solicitation. Proposals will be screened for stewardship relevance and then reviewed for scientific and technical merit by qualified individuals. The review and selection process for each funding opportunity are included in the solicitation. Decisions to approve are made by a Headquarters program official within the Program Office. Selected proposals will be forwarded to the NNSA's Office of Partnership and Acquisition Services for grant development, negotiation, and award.

Time to approval or disapproval

Approximately 90 to 180 days.

Renewals

Proposals for renewal should be submitted to the next open funding opportunity announcement.
