Research Reactor Division
Aerial View of HFIR
The Research Reactors Division is responsible for operation of the High Flux Isotope Reactor (HFIR). The 85-megawatt reactor is the highest flux reactor-based source of neutrons for condensed matter research in the United States. Thermal and cold neutrons produced by HFIR are used for studies in a variety of scientific fields. The neutron scattering capabilities of this facility provide knowledge about the molecular and magnetic structures and behavior of materials, including high-temperature superconductors, polymers, metals, and biological samples.
Capabilities
In recent years, HFIR has undergone the most dramatic transformation in its 40-year life. Improvements include an overhaul of the reactor structure for reliable, sustained operation; installation of a liquid hydrogen cold source; a new neutron guide hall that can house seven new cold-neutron instruments; and significant upgrading of the eight thermal-neutron spectrometers and diffractometers in the beam room. The facility has 11 instruments planned or in operation.
The division is composed of about 180 staff and is lead by Director Ronald Crone.
