Computational Fluid Dynamics Modeler (Early Career)

Oak Ridge National Laboratory•Oak Ridge, TN

About The Position

Oak Ridge National Laboratory is seeking an early-career Computational Fluid Dynamics (CFD) modeler to apply modeling tools to simulate complex fluid behavior at all scales in support of isotope enrichment. The successful candidate will collaborate with computer scientists and experimental facilities to develop verified models focused on enrichment technologies. The role is in the Gas Testing & Simulation Group, within the Separative Performance Engineering & Testing Section of the Centrifuge Enrichment Technology Division, Isotope Science and Enrichment Directorate. The group applies machine and cascade theory to develop, simulate, execute, and interpret testing evolutions for discovery, performance evaluation, and optimization of enrichment systems. The modeler will provide research and development support to advance prototype enrichment devices for processing uranium-bearing and stable isotope process gases. The position requires the ability to obtain and maintain a Department of Energy Q clearance and is designated for Workplace Substance Abuse Program testing. Visa sponsorship is not available. Relocation assistance may be available for certain positions. ORNL offers medical and retirement plans, flexible work hours, on-site amenities, and additional employee benefits.
