The Oak Ridge Site, located in eastern Tennessee, is one of the three original sites in the Manhattan Project. The K-25 and Y-12 plants were built to explore different methods to enrich uranium, while the X-10 Site was established as a pilot plant for the Graphite Reactor and to explore methods for the production of plutonium. Throughout the following decades, the three sites purified isotopes, conducted advanced research, manufactured weapons components, and enriched uranium. These activities created environmental legacies that placed the Oak Ridge Reservation on EPA’s National Priorities List in 1989. Watch the video below to learn more about the cleanup progress and transformation happening at the Oak Ridge Site.
