About The Position

We are seeking a Computational Fluid Dynamics (CFD) modeler to apply modeling tools to simulate the complex behavior of fluids at all scales to support isotope enrichment. A successful candidate will collaborate with computer scientists and experimental facilities to develop verified models focused on enrichment technologies. This position resides in the Gas Testing & Simulation Group in the Centrifuge Science Section, Enrichment Science and Engineering Division, Isotope Science and Engineering Directorate, at Oak Ridge National Laboratory (ORNL). This group leads the application of machine and cascade theory to develop, simulate, execute, and interpret testing evolutions for discovery, performance evaluation, and optimization of enrichment systems. As part of our team, you will provide research and development (R&D) support to strategically advance science and technology of prototype enrichment devices for processing both uranium-bearing and stable isotope process gases. The Oak Ridge National Laboratory (ORNL) is one of the nation’s largest multi-program science and technology laboratories within the U.S. Department of Energy (DOE). The Enrichment Science and Engineering Division (ESED) at ORNL is tasked with advancing enrichment technologies and exploring stable isotope production and application. The division leverages an elite staff of scientists and engineers with the world-leading capabilities of ORNL to deliver groundbreaking advancements with a variety of applications, from national security to life-saving medical treatments.
