Oak Ridge Y-12 National Security Complex

The Y-12 National Security Complex (NSC) resides in an especially beautiful part of Tennessee. Though situated in a valley between the Great Smoky Mountains and the Cumberland Mountains, the facility is not at all difficult to reach. The Y-12 Complex is only minutes from the City of Oak Ridge, under 30 minutes from Knoxville.
