Protecting America's Future — The Y-12 National Security Complex stands ready to address the existing and emerging national security challenges facing our nation and our world today.

The Y‑12 National Security Complex is one of four production facilities in the National Nuclear Security Administration’s Nuclear Security Enterprise. Our unique emphasis is the processing and storage of uranium and development of technologies associated with those activities. Decades of precision machining experience make Y‑12 a production facility with capabilities unequaled nationwide.

Y‑12 maintains the safety, security and effectiveness of the U.S. nuclear weapons stockpile. We also reduce the global threat posed by nuclear proliferation and terrorism, and provide safe and effective nuclear propulsion systems for the U.S. Navy.

Y‑12 has become the complex that the nation looks to for support in protecting America’s future by applying our state-of-the-art capabilities in three core areas

  • nuclear technology and materials;
  • security and consequence management; and
  • manufacturing and technical services.

Using our skill in precision manufacturing and handling of nuclear materials, we provide solutions for a variety of emerging global security challenges. Products and processes that we develop for use in a high-consequence production setting strengthen the science, technology and engineering competencies at the foundation of the NNSA’s missions.

We actively seek partnerships to commercialize these technologies, which have applications for allies, other government agencies and the private sector.

B&W Y‑12, a partnership of the Babcock & Wilcox Company and Bechtel Corporation, operates Y‑12 under contract to the U.S. Department of Energy, of which the NNSA is a part.
