What You Will Do

The Systems Design and Analysis Group (NEN-5) is seeking an experienced, high-performing R&D Engineer 4 to work in the area of nuclear system design, ranging from development of computational methodologies to simulations of nuclear reactors. Our staff focuses upon special purpose reactor design and demonstration for space and terrestrial applications, radiation transport code applications, high fidelity simulation of nuclear systems and nuclear fuels, systems modeling, nuclear fuel cycles and nuclear security. Recent successes include the design, development, and testing of a prototype fission reactor named Kilowatt Reactor Using Stirling Technology (KRUSTY). Our diverse workforce enjoys a collegial work environment focused on creative problem solving, where everyone’s opinions and ideas are considered. Depending on the specific skill set of the selected candidate, there will be opportunities to work in one or more of the following areas:

  • Lead technical research on analysis of advanced reactor designs.

  • Solve important and challenging radiation transport and reactor safety problems for a variety of applications.

  • Develop and apply tools for high‐fidelity simulations of reactor systems.

  • Perform high‐fidelity computational modeling for a range of phenomena including neutronics, thermal hydraulics, nuclear fuel performance and/or other thermo‐mechanical processes.

  • Analyze reactor designs, including analysis of issues related to neutronics, structural mechanics, heat transfer, fluid flow, and/or safety.

The successful candidate will be required to:

  • Execute and provide technical leadership for high quality modeling and/or simulation research in a nuclear-related field within the group.

  • Participate in a fast-paced work environment to interface between multiple reactor design disciplines and perform important reactor safety calculations.

  • Interface with sponsors and other laboratories to communicate information and meet common needs. Define program strategies in concert with stakeholders.

  • Actively participate in recruiting and mentoring of students and early career staff.

  • Document and/or present advanced technical work clearly and effectively.

  • Undertake domestic travel as periodically required based on programmatic needs.

There are opportunities for technically advanced work performed here to be published in journals or conference proceedings.
