Oak Ridge National Laboratory (ORNL) is a U.S. multiprogram science and technology national laboratory sponsored by the U.S. Department of Energy (DOE) and administered, managed, and operated by UT–Battelle as a federally funded research and development center (FFRDC) under a contract with the DOE.
Oak Ridge National Laboratory is managed by UT–Battelle, a limited liability partnership between the University of Tennessee and the Battelle Memorial Institute, formed in 2000 for that purpose. The annual budget is US$2.4 billion. As of 2021, there is 5,700 staff working at ORNL and an additional 3,200 guest researchers annually.
The ORNL site occupies approximately 4,470 acres and includes facilities in two areas—Bethel Valley and Melton Valley. Bethel Valley, which includes the central campus area of ORNL, includes reactor facilities, isotope production facilities, waste treatment facilities, and research facilities.
There are five campuses on the Department of Energy’s Oak Ridge reservation; the National Laboratory, the Y-12 National Security Complex, the East Tennessee Technology Park (formerly the Oak Ridge Gaseous Diffusion Plant), the Oak Ridge Institute for Science and Education, and the developing Oak Ridge Science and Technology Park, although the four other facilities are unrelated to the National Laboratory. The total area of the reservation is 150 square kilometers (58 sq mi) of which the lab takes up 18 square kilometres (7 sq mi).
ORNL scientific programs focus on materials, neutron science, energy, high-performance computing, systems biology and national security, sometimes in partnership with the state of Tennessee, universities and other industries.
It has several of the world’s top supercomputers, including Summit, ranked by the TOP500 as Earth’s second-most powerful. The lab is a leading neutron and nuclear power research facility that includes the Spallation Neutron Source the High Flux Isotope Reactor, and the Center for Nanophase Materials Sciences.
