The Fusion Energy Division at the Oak Ridge National Laboratory seeks applications for a skilled Computational Fluid Engineer, with intended focus on helium gas cooling. The selected candidate will work on and lead various projects in the development of technical solutions for fusion energy component design and experiments. The Fusion Energy Division (FED) at Oak Ridge National Laboratory (ORNL) invites applicants for a Helium Gas Cooling position in Fusion Blankets and Enginneering Design. The FED is developing the technical basis for the first fusion nuclear facility and involves a number of disciplines, particularly helium gas cooling. A helium flow loop experiment has been completed, and this is coupled to extensive computations to explore the helium flow behavior and corresponding thermal performance in both test articles and also future fusion blankets and other fusion core components. We seek individuals with advanced technical and analytical skills who can lead both experimental and computational activities. The successful candidate will work with a multidisciplinary team of experimentalists, simulation/design, and technology experts.

Job Duties and Responsibilities: The successful candidate will be involved in both developing new and applying existing models and simulation tools to understand fusion blanket processes and their design optimization. This is concentrated on helium computational fluid dynamics, but may involve thermal hydraulics, mass and heat transfer, materials, and hydrogen behavior. In addition, leading and participating in helium experiments, as well as contributing to the development of the experiment hardware is expected. The selected candidate will be responsible for interaction with division staff and the external collaborators that work with the ORNL research group. The candidate will be expected to work independently, lead, perform and collaborate on simulation/design activities and associated experiments, fully document work in technical reports and publications, contribute to the identification and development of research proposals.

Basic Qualifications:

  • The successful candidate must have completed a Ph.D. in Nuclear Engineering, Thermal-Mechanics, Fluids, Material-engineering interface or a closely related field.
  • It is required for candidates to have experience in the development and application of complex engineering codes and preferable to have familiarity with nuclear systems. Experimental opportunities and development of experimental capability exist, and the candidate would be expected to lead or participate, as well as participate on multi-institutional and multi-discipline design teams.
  • Candidates must show examples of their academic and work experience.

Relocation: Moving can be overwhelming and expensive. UT-Battelle offers a generous relocation package to ease the transition process. Domestic and international relocation assistance is available for certain positions. If invited to interview, be sure to ask your Recruiter (Talent Acquisition Partner) for details.
