NEI's mission is to promote the use and growth of nuclear energy through efficient operations and effective policy. The Nuclear Energy Institute is the member-based policy organization of the leading clean energy source in the United States.
Nuclear Energy Institute Inc. uses its grantmaking to support nuclear energy policy, advocacy, and deployment through a mix of large contributions and sponsorships. The clearest signal in the recent record is repeated support for Nuclear Matters, which received $2,300,000 in 2025 after $2,000,000 in both 2024 and 2023. That multi-year pattern suggests a sustained relationship around nuclear energy messaging and policy work. Beyond that flagship recipient, the foundation backs organizations that work in the policy and technical ecosystem around nuclear power. It gave $102,500 to the National Conference of State Legislatures in 2024 and $90,000 to the Bipartisan Policy Center in 2025, alongside support for the American Nuclear Society and the National Association of Regulatory Utility Commissioners. These grants fit a funder whose stated mission is to promote the use and growth of nuclear energy through efficient operations and effective policy. The overall profile is shaped by short-term, project-specific support rather than individual giving or program-related investments. The foundation’s recent awards also show a preference for organizations that can influence state and federal decision-making, industry practice, and public understanding of nuclear energy.
In nuclear energy policy and advocacy, the foundation backed multiple civic and policy organizations. It gave $100,000 to the Republican Attorneys General Association and $100,000 to the Democratic Lieutenant Governors Association in 2024, showing support across partisan and state-government channels. For regulatory and technical guidance, it awarded $90,000 to the American Nuclear Society in 2024 and $35,000 to the National Association of Regulatory Utility Commissioners in 2024, with an earlier $31,000 sponsorship to the same utility-regulator group in 2023. Those grants point to work with professionals and regulators who shape nuclear standards and oversight. It also funds clean-energy and advanced-nuclear advocacy. In 2023, the United Coalition for Advance Nuclear Power received $50,000, while the Energy Innovation Reform Project received $20,000 that same year. These grants sit alongside support for policy groups focused on energy strategy and climate.
