Oak Ridge National Laboratory

The U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) is the nation’s largest multi-program science and technology laboratory. ORNL's mission is to deliver scientific discoveries and technical breakthroughs that will accelerate the development and deployment of solutions in clean energy and global security. Today, ORNL pioneers the development of new energy sources, technologies, and materials and the advancement of knowledge in the biological, chemical, computational, engineering, environmental, physical, and social sciences.

Y-12 National Security Complex

The Y-12 National Security Complex is one of the nation’s most important national security assets. The 811 acre site contains the nation’s stockpile of highly enriched uranium and also performs nuclear non-proliferation missions. Historically, Y-12’s operations focused on a uranium enrichment method that used vast amounts of mercury. Over the years, nearly 700,000 pounds of mercury leaked from machines and pipes into the environment.

East Tennessee Technology Park

For 40 years, the 2,200-acre East Tennessee Technology Park was home to a complex of facilities that enriched uranium. The site dates back to the World War II Manhattan Project. In addition to defense missions, the plant produced enriched uranium for the commercial nuclear power industry from 1945 to 1985. In 1987, DOE terminated uranium enrichment operations in Oak Ridge and closed the site. As a result of these operations, ETTP has a legacy of contaminated buildings, soil, sediment, and groundwater that require remediation for the protection of human health and the environment.

Waste Disposal

The low-level radiological and hazardous wastes generated from Oak Ridge’s cleanup projects are disposed in the Environmental Management Waste Management Facility (EMWMF). The EMWMF is comprised of six disposal areas that have a total capacity of 2.2 million cubic yards. EM ensures waste is accurately characterized so materials sent to the disposal area comply with all of the regulations included in the Comprehensive Environmental Response, Compensation, and Liability Act.
