Oak Ridge National Laboratory (ORNL), established in 1943 and under the jurisdiction of the U.S. Department of Energy, is one of the most important national laboratories in the United States. As part of the Manhattan Project, ORNL's initial mission was to produce and isolate uranium and plutonium, providing crucial materials for the development of the atomic bomb. Over time, the laboratory's research areas have expanded to include neutron science, energy science, chemistry and radiochemistry, environmental science, robotics, supercomputers, mathematics, and many other fields.
Historical background of Oak Ridge National Laboratory
Oak Ridge National Laboratory's history dates back to World War II. At that time, the U.S. government launched the Manhattan Project to gain a leading position in nuclear weapons development.
