The Nuclear Safety and Experiment Analysis (NSEA) Group within the Research Reactors Division (RRD), Neutron Sciences Directorate (NScD), Oak Ridge National Laboratory (ORNL), seeks applications for an applied Research and Development (R&D) Principal Experiment Safety Engineer.

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 carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical sciences. 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.
