The Y‑12 National Security Complex is a premier manufacturing facility dedicated to making our nation and the world a safer place and plays a vital role in the Department of Energy’s Nuclear Security Enterprise.
Y‑12 helps ensure a safe and effective U.S. nuclear weapons deterrent. We also retrieve and store nuclear materials, fuel the nation’s naval reactors, and perform complementary work for other government and private-sector entities.
Since 1943, Y‑12 has played a key role in strengthening our country’s national security and reducing the global threat from weapons of mass destruction.
Y‑12 has evolved to become the complex the nation looks to for support in protecting America's future, developing innovative solutions in manufacturing technologies, prototyping, safeguards and security, technical computing and environmental stewardship.
