Y-12 National Security Complex

The Y-12 National Security Complex (Y-12) serves as the nation’s only source of enriched uranium nuclear weapons components and provides enriched uranium for the U.S. Navy. Y-12 is a leader in materials science and precision manufacturing and serves as the main storage facility for enriched uranium. Y-12 also supports efforts to reduce the risk of nuclear proliferation and performs complementary work for other government agencies.

It is managed by the NNSA Production Office, which is responsible for contract management and oversight of the Pantex Plant in Amarillo, Texas and the Y-12 National Security Complex in Oak Ridge, Tenn.
