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.
The Spallation Neutron Source (SNS) is a recently completed accelerator-based neutron source that provides the most intense pulsed neutron beams in the world for scientific and industrial research and development. With its eventual suite of up to 25 best-in-class instruments, SNS will give researchers detailed snapshots of smaller samples of physical and biological materials than previously possible. The diverse applications of neutron scattering research will provide opportunities for experts in practically every scientific and technical field.
The 85-MW High Flux Isotope Reactor (HFIR) provides one of the highest steady-state neutron fluxes of any research reactor in the world. HFIR fulfills four missions: isotope production, materials irradiation, neutron activation, and neutron scattering, which is the focus of this report. The neutron scattering instruments at HFIR enable fundamental and applied research into the molecular and magnetic structures and behavior of materials. HFIR has 15 instruments planned or in operation. A new cold neutron source installed during a HFIR refurbishment in 2006–2007 greatly enhances the reactor’s research capabilities, particularly in the biological sciences.
- High-performance computing The National Center for Computational Sciences (NCCS) provides the most powerful computing resources in the world for open scientific research. It is a research environment that supports advances in understanding how the physical world works and using that knowledge to address national and international concerns. The NCCS was founded in 1992 and is managed by the Advanced Scientific Computing Research program of the U.S. Department of Energy’s Office of Science.
The Center is home to the Cray XT high-performance computing system, called Jaguar. The system has a peak performance of 1.64 petaflops (quadrillion floating point operations, or calculations) per second. To support its concentration of computing power, the NCCS has installed high-speed fiber-optic networks to expedite data movement, a scientific visualization center that enables researchers to analyze their simulation results quickly and comprehensively, and a high-performance data archiving and retrieval system.
NCCS hosts only those projects capable of producing groundbreaking results. Each year a few research efforts that require enormous computing resources are allocated as much as several million processor-hours of computing time. Such unprecedented levels of computational power are key to investigating areas, such designing fusion reactors that could provide clean, virtually unlimited energy; engineering proteins to provide new therapies for diseases and release energy from biomass efficiently; studying climate change; and designing new materials with specialized properties.

Facts and Figures
ORNL is managed by a limited liability partnership between the University of Tennessee and Battelle Memorial Institute known as UT-Battelle.
ORNL has a staff of over 4,300 full-time staff members, including 1500 scientists and engineers. The laboratory annually hosts approximately 3,000 who spend two weeks or longer in Oak Ridge; about 25 percent of these are from industry. ORNL receives 30,000 visitors each year, plus another 10,000 precollege students.
ORNL funding for FY 2007 exceeds $1.2 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 $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 km²), 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 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.
