Description

The Federal Nuclear Security Administration (FNSA) was established within the Union of Columbia Bureau of Energy (UBE) following the Bureau’s creation in 1958, as nuclear technology and strategic energy programs required dedicated federal oversight. As a semi-autonomous administration, the FNSA was tasked with safeguarding nuclear materials, facilities, and sensitive programs while supporting the Bureau of Energy’s broader mission of national energy security and scientific advancement. Today, the FNSA operates under the authority of the Bureau of Energy, ensuring the secure stewardship and protection of the Union’s nuclear enterprise in coordination with other federal and state partners.
