Summary
The National Nuclear Security Administration (NNSA), a semi-autonomous agency within the United States (U.S.) Department of Energy (DOE), prepared this environmental assessment (EA) for the East End Campus at the Y-12 National Security Complex, Oak Ridge, Tennessee (DOE/EA-2130). The EA analyzes the potential environmental effects of constructing and operating the East End Campus, which would provide a robust radiation case manufacturing capability to meet national security stockpile requirements, as well as support other Y-12 missions.
