US Army Announces Project Janus for Advanced Nuclear Reactors Under DOE and DOW Oversight

The U.S. Army's Project Janus, set for fall 2025, will deploy advanced reactors on military installations in partnership with the DOE, leveraging legal authorities under the Atomic Energy Act. This initiative reflects a broader government push for advanced nuclear deployment to enhance energy resilience and national security, following Executive Orders 14299 and 14301. The DOE can authorize reactors for internal and mission-driven purposes without NRC licensing, while DOW's authority enables military-related projects to bypass NRC regulations.

The DOE can construct reactors for internal purposes without Nuclear Regulatory Commission (NRC) licensing. In contrast, the Department of War (DOW) can authorize military reactors exempt from NRC regulation. Project Janus will utilize Other Transaction Agreements for execution, raising issues of nuclear risk indemnification as it falls outside typical DOE and NRC frameworks.
