Nuclear Challenges Grant Guidelines


We advance an ambitious strategy to reduce the nuclear threat, particularly by decreasing the availability of and reliance on weapons-useable nuclear material and by protecting and strengthening the overarching nuclear regime. We provide support to a broad range of nongovernmental institutions including universities, think tanks, and research centers from around the world. Individuals are not eligible to receive support unless they are affiliated with or sponsored by an institution.

We are committed to continual improvement of our grantmaking strategy by regularly engaging with independent experts, government officials, and private industry representatives from inside and outside the nuclear sphere. We also rely on a cohort of internal and external advisors for input and guidance.  
Our portfolio is comprised of a variety of awards—from targeted rapid response projects lasting a few months or less, to multi-million-dollar, multi-year grants in support of general operations. A given award tends to include policy-relevant scholarship, stakeholder engagement, and/or outreach and dissemination of policy prescriptions.
We are currently accepting letters of inquiry in our areas of focus for a limited number of grants. We are particularly interested projects that address new components of our strategy, focusing on:

  • a new nuclear policy vision;
  • the state of U.S. alliance relationships and implications for proliferation;
  • and the impasse between countries that possess nuclear weapons and those that do not.

We encourage letters of inquiry from diverse perspectives, new voices, and interdisciplinary teams and will consider funding applications without regard to race, religion, ethnicity, gender identity, sexual orientation, age, marital or veteran status, medical condition, disability, or any other legally protected status under federal, state, or local law.

For the current round of consideration, please submit letters of inquiry by May 31, 2019. Letters of inquiry should include a one- to two-page narrative description of your idea and a one-page budget summary.

The letters of inquiry can be for the following types of grants:

  • One- to two-year grants of up to $500,000. Proposed budgets should not exceed $250,000 per year.
  • Short-term rapid response grants of up to $50,000 for conferences and convenings, small research projects, or travel. These grants can be made only to U.S. public charities or equivalents.
