Nuclear Engineer

Job ID 1795 Date posted 07/10/2019


Brookhaven National Laboratory is a multipurpose research institution funded primarily by the U.S. Department of Energy’s Office of Science. Located on the center of Long Island, New York, Brookhaven Lab brings world-class facilities and expertise to the most exciting and important questions in basic and applied science—from the birth of our universe to the sustainable energy technology of tomorrow. We operate cutting-edge large-scale facilities for studies in physics, chemistry, biology, medicine, applied science, and a wide range of advanced technologies. The Laboratory's almost 3,000 scientists, engineers, and support staff are joined each year by more than 4,000 visiting researchers from around the world. Our award-winning history, including seven Nobel Prizes, stretches back to 1947, and we continue to unravel mysteries from the nanoscale to the cosmic scale, and everything in between. Brookhaven is operated and managed by Brookhaven Science Associates, which was founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, and Battelle, a nonprofit applied science and technology organization.



Brookhaven National Laboratory’s Department of Nuclear Science and Technology serves as a resource for nuclear physics research and nuclear technologies such as reactors, accelerator driven systems, and isotope applications.  It supports the missions of the Department of Energy, the Nuclear Regulatory Commission, and other national and international organizations. With a world-class staff of professionals with expertise in a broad range of areas so that it can work in materials science, reactor physics, thermal-hydraulics, structural mechanics, human factors, mechanical engineering, risk analysis, and nuclear physics.

The Nuclear Systems & Structural Analysis Group is part of BNL’s Nuclear Science and Technology Department. The mission of the group is to provide nuclear and engineering analysis support in matters related to nuclear reactor design and safety, non-reactor nuclear facilities, nuclear fuel cycles, and proliferation resistance and physical protection of nuclear energy systems.



The Nuclear Systems & Structural Analysis Group has an opening for an assistant scientist in nuclear engineering. The incumbent will complement other experts in the group for neutronics and reactor system analysis, including power and research reactors.



Essential Duties and Responsibilities: 

  • Perform modeling and simulation, oriented towards nuclear reactor physics, fuel performance evaluation and fuel cycle analysis.
  • Use state-of-the-art computational tools to perform analyses.
  • Assist in the evaluation and validation of nuclear data.
  • Assist in identifying opportunities for expanding programs and interact with funding agencies to help obtain those programs.

Required Knowledge, Skills, and Abilities:

  • Ph.D. in nuclear engineering or closely related field.
  • Relevant areas of expertise are: analysis of fast and thermal nuclear reactor systems, including standalone neutronics analysis and coupled neutronics-thermal hydraulics analysis, fuel cycle analysis, including dynamic fuel cycle behavior and economic analysis, and/or analytical evaluation of advanced fuel performance.
  • Demonstrated capacity for creative problem solving and skills required to deliver project-specific products and services to customers in accordance with contractual requirements. 
  • Have good communication skills and demonstrated ability to write clear, well documented reports and papers for publication and make effective presentations at technical meetings.

Preferred Knowledge, Skills, and Abilities:

  • Proficiency with state-of-the-art neutronic and/or fuel cycle analysis computational tools, such as, stochasic neutronics tools (Serpent, MCNP), deterministic neutron transport tools (SCALE/TRITON/NEWT, MCC), deterministic nodal or diffusion tools (PARCS, DIF3D/REBUS), dynamic fuel cycle analysis tools (VISION), or fuel performance tools (BISON, FAST, FRAPCON, FRAPTRAN).
  • Some experience with thermal hydraulic or systems analysis using TRACE/RELAP5.
  • Programming and computing skills in FORTRAN, C++ and Python.
  • Artificial intelligence and machine learning.

OTHER INFORMATION: (add if applicable)

  •  Ability to obtain and retain a Q clearance.
  • Ability to travel both domestically and internationally as required for project work and laboratory representation
