Deploying Advanced Nuclear Reactor Technologies for National Security

This Executive Order directs an accelerated federal effort to develop and deploy advanced nuclear reactor technologies to support U.S. national security, energy resilience, and global nuclear leadership. It mandates the use of nuclear power at defense and Department of Energy (DOE) sites, facilitates siting and fuel support for privately funded reactors, and strengthens interagency coordination. The order also promotes U.S. nuclear exports through expanded international agreements and financing strategies, and streamlines NEPA compliance. It seeks to enhance the domestic nuclear fuel cycle, ensure a long-term enriched uranium supply, and prioritize security clearances to support rapid deployment.
