The National Security mission in Oak Ridge is carried out at the National Nuclear Security Administration's (NNSA) Y-12 National Security Complex, formerly known as the Oak Ridge Y-12 Plant. Programs at Y-12 include manufacturing and reworking nuclear weapon components, dismantling nuclear weapon components returned from the national arsenal, serving as the nation's safe, secure storehouse of special nuclear materials, reducing the global threat from terrorism and weapons of mass destruction, and providing the U.S. Navy with safe, militarily effective nuclear propulsion systems. Y-12 is operated by B&W Y-12 LLC. ORO provides a variety of services to the NNSA's Y-12 Site Office as part of a service agreement between the two organizations.
