Job Location: Oak Ridge, TN

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: The Nuclear Safety and Experiment Analysis (NSEA) Group within the Research Reactors Division (RRD), Neutron Sciences Directorate (NScD), Oak Ridge National Laboratory (ORNL), seeks early to mid-career applicants for an applied Research and Development (R&D) staff position as a nuclear safety analyst to support the HFIR. In this capacity, you will be a member of the NSEA Group within RRD providing analytical support to the safe reliable operation of the HFIR. In particular, we are seeking self-motivated, details-oriented, safety analysis support for the supercritical hydrogen HB-4 Cold Source facility.

Major Duties/Responsibilities:
--Preparation and maintenance of the Cold Neutron Source Documented Safety Analysis (CS DSA) and the HFIR Technical Safety Requirements (TSRs). Ancillary support and interfacing with the HFIR SAR may be required as needed.--Assuring technical compliance with 10 CFR Part 830 Subparts A and B, affecting reactor safety, through implementation of ORNL Standards Based Management System (SBMS) and RRD procedures.--Assisting other RRD groups with the resources necessary to comply with nuclear safety requirements relative to their respective functions, disciplines and responsibilities.
