Oak -Ridge National Laboratory

Oak Ridge, Tennessee, USA


The Systems Engineering (SE) group within the Research Reactors Division (RRD) is looking for a highly motivated individual to join the SE team. The primary responsibility of the SE group is to maintain the HFIR configuration management program, provide technical support to operations and maintenance, and perform systems analysis. This position will be responsible for the Mechanical Engineering role in the SE group which performs design engineering and supports manufacturing and fabrication of reactor core components, fuel elements, control rods and plates, etc. This position will also be responsible for maintaining overall cognizance of assigned HFIR structures, systems, and components (SSC) and providing systems engineering support for operations and maintenance.

Description of Institution

The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor (HFIR), the United States’ highest flux reactor-based neutron source, and the Spallation Neutron Source (SNS), the world’s most intense pulsed accelerator-based neutron source. Together, these facilities operate 30 instruments for neutron scattering research. Each year, these facilities carry out more than 1,000 experiments in the physical, chemical, materials, biological and medical sciences for more than 3,000 visiting scientists. HFIR also provides unique facilities for isotope production and neutron irradiation. To learn more about Neutron Sciences at ORNL go to: http://neutrons.ornl.gov.
