Oak Ridge National Laboratory ('''ORNL''') is a multiprogram science and technology National Laboratory managed for the United States Department Of Energy by UT-Battelle, LLC . ORNL is located in Oak Ridge , Tennessee , near Knoxville . Scientists and engineers at ORNL conduct Basic and Applied Research And Development to create scientific knowledge and technological solutions that build the nation's expertise in key areas of science; increase the availability of clean, abundant Energy ; restore and protect the Natural Environment ; and contribute to National Security . ORNL also performs other work for the Department of Energy, including Isotope production, Information Management , and technical Program Management , and provides Research and technical assistance to other organizations. RESEARCH PROGRAMS ORNL conducts research and development activities that span a wide range of scientific disciplines. The laboratory's major research areas are described briefly below.
RESEARCH FACILITIES Oak Ridge National Laboratory is home to a number of highly sophisticated experimental research facilities. These research laboratories are designed to serve staff scientists and engineers, as well as researchers from universities, industry, foreign institutions, and other government laboratories. For more information about these facilities, see the laboratory's research facilities website. User Facilities Some ORNL research facilities have been designated as "user facilities" by the U.S. Department of Energy. Work at user facilities may be conducted on a nonproprietary or proprietary basis. More information on these facilities and how to gain access to them, is available on laboratory's user facilities website . FACTS AND FIGURES ORNL has a staff of more than 4,200, including 1500 scientists and engineers. The laboratory annually hosts approximately 3,000 guest researchers who spend two weeks or longer in Oak Ridge; about 25 percent of these visitors are from industry. ORNL receives 30,000 visitors each year, plus another 10,000 precollege students. ORNL funding for FY 2006 exceeds $1 billion; 80 percent of that amount comes from the Department of Energy, and 20 percent is from other federal and private customers. UT-Battelle, the laboratory's management and operating contractor, has provided nearly $8 million in support of math and science education, economic development and other projects in the greater Oak Ridge Region . The laboratory occupies about 58 square miles (150 km&2), and the replacement cost of its buildings is estimated to be about $7 billion. HISTORY The facility that later became Oak Ridge National Laboratory was established as part of the Manhattan Project in 1943, during World War II when American scientists feared that Nazi Germany was rapidly developing an Atomic Bomb . Both the laboratory and the nearby city of Oak Ridge were built by the United States Army Corps Of Engineers in less than a year on isolated farmland in the mountains of East Tennessee. Oak Ridge became a "secret city" that within two years housed more than 75,000 residents. The goal of the Manhattan Project activities in Oak Ridge was to separate and produce Uranium and Plutonium for use in developing a nuclear weapon. This work was carried out in four facilities, code-named X-10 (later to become Oak Ridge National Laboratory), Y-12 , K-25 , and S-50 . X-10 was a demonstration plant for the process to produce plutonium from uranium by nuclear bombardment. Y-12 was dedicated to the Electromagnetic Separation of U-235. K-25 was a Gaseous Diffusion plant designed to separate U-235 from U-238 and was also home to the the S-50 liquid thermal diffusion plant. Working under assumed names, in 1943 Enrico Fermi and his colleagues developed the X-10 Graphite Reactor , the world's first production Nuclear Reactor , to demonstrate the production of plutonium. This built on work done by Fermi and his colleagues at the University of Chicago in 1942 which created the world's first experimental nuclear reactor Chicago Pile-1 and the first sustained nuclear reaction on December 2, 1942. The plutonium production piloted at X-10 was carried out on a much larger scale at the Hanford Site , which produced the plutonium used in the " Fat Man " Atomic Bomb that was dropped on Nagasaki, Japan in August 1945. ORNL's involvement with nuclear weapons ended after the war. The laboratory's scientific expertise shifted in the 1950s and 1960s to peacetime research in medicine, biology, materials and physics. During this period the Graphite Reactor was used to produce the world's first medical Radioisotopes for treating cancer. Following the creation of the U.S. Department of Energy in 1977, ORNL's mission broadened to include research in Energy Production , Transmission and Consumption . The end of the Cold War and the growth of international Terrorism led to a further expansion of research into a range of national security-related technologies. As the laboratory entered the 21st century, new cross-disciplinary programs in Nanophase Materials , Computational Sciences and Biology has led to the term "nano-info-bio" to describe the emerging synthesis in ORNL's research agenda.
