Senior R&D Staff Member - Sensitivity/Uncertainty Methods Developer and Analyst for Nuclear Reactors

Date: Sep 19, 2021

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 6095 

Overview: 

Oak Ridge National Laboratory (ORNL) is the largest United States (U.S.) Department of Energy (DOE) science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security. Our diverse capabilities span a broad range of scientific and engineering disciplines, enabling the Laboratory to explore fundamental science challenges and to carry out the research needed to accelerate the delivery of solutions to the marketplace. 

 

We are seeking a Senior Research & Development (R&D) Staff Member – Sensitivity/Uncertainty Methods Developer and Analyst for Nuclear Reactors, who will support the Nuclear Transmutation Decay Physics Group in the Nuclear Modeling and Simulation Development and Deployment Section, Nuclear Energy and Fuel Cycle Division, Fusion and Fission Energy and Science Directorate at ORNL. The Nuclear Transmutation & Decay Physics Group develops application methodologies and simulation software and performs analysis to address national priorities in nuclear energy performance and safety. 

 

 

 

Major Duties/Responsibilities: 

  • Development of new sensitivity analysis and uncertainty quantification methodologies and capabilities within ORNL’s SCALE code system to support the U.S. Nuclear Regulatory Commission and U.S. DOE sponsor needs.
  • Lattice physics analysis for Light Water Reactors (LWRs) and Advanced Reactors (non-LWR designs).
  • Verification and validation (V&V) of production-quality nuclear software for neutronics or multiphysics applications for global distribution, with particular emphasis on V&V tools that simulate isotopic evolution in reactor systems, such as SCALE/ORIGEN, including ability to investigate root cause of discrepancies due to inadequate nuclear data.
  • Contributing to internal software testing and V&V for the SCALE and VERA code systems.
  • Leading of small teams of diverse staff to solve challenging problems.
  • Performing individual and collaborative R&D for complex problems and communicating the technical aspects of the work performed through publications and presentations.
  • Effectively interacting with technical peers, program managers, and sponsors, both domestically and internationally, to meet the requirements of projects within scope, schedule, and budget.
  • Accepting responsibility and contributing expertise to ongoing and future research projects, defining objectives and approaches to ensure technical and programmatic success.
  • Contributing to the identification and development of research proposals through work with project sponsors and internal and external collaborators.

 

Basic Qualifications:

  • Requires:
    • A Doctor of Philosophy (Ph.D.) in nuclear engineering or related discipline and at least 7 years of post-graduate experience, or
    • A Master of Science (M.S.) in nuclear engineering or related discipline and at least 13 years of post-graduate experience, or
    • A Bachelor of Science (B.S.) in nuclear engineering or related discipline and at least 16 years of post-graduate experience.
  • Demonstrated knowledge/understanding of standard sensitivity and uncertainty methods such as adjoint-driven sensitivity analysis and sampling-based uncertainty analysis.
  • Knowledge of sensitivity analysis  and uncertainty quantification R&D applied to nuclear reactor analysis, as demonstrated through research and associated publications. Candidates must have a strong publication record.
  • Excellent written and oral communication skills.
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.

 

Preferred Qualifications:

  • A Doctor of Philosophy (Ph.D.) in nuclear engineering or related discipline and at least 12 years of post-graduate experience, or
  • A Master of Science (M.S.) in nuclear engineering or related discipline and at least 16 years of post-graduate experience, or
  • A Bachelor of Science (B.S.) in nuclear engineering or related discipline and at least 20 years of post-graduate experience.
  • Demonstrated experience with computational software systems for sensitivity analysis and uncertainty quantification within nuclear science and engineering applications, such as SCALE, MCNP, Serpent.  
  • Familiarity with a wide range of reactor systems and concepts.
  • R&D experience on the impact of nuclear data on reactor physics applications.
  • Modern software development experience with C, C++, and/or Fortran.
  • Python programming experience for scripting and automation.
