ReactorCoreThermalFluidsEngineer

Thanks for your interest in Oklo! We are searching for a Thermal Fluids Engineer to join our Core Thermal-Hydraulics team. Position Description The Core Thermal-Hydraulics team at Oklo is responsible for analyzing fluid flow and heat transfer within a reactor core. The work includes engineering analyses of thermal-fluid dynamics, clear and thorough documentation of the analyses, as well as interfacing with design teams. A engineer on the team will contribute to the development, qualification, and validation of methods for modeling coolant flow within reactor cores using one-dimensional models, intermediate-fidelity subchannel models, and high-fidelity computational fluid dynamics models. Specific responsibilities may include: Modeling core thermal-hydraulic behavior using subchannel codes such as DASSH, MOOSE-Subchannel, or COBRA-TF one-dimensional systems codes such as SAS4A/SASSYS-1 or RELAP first principles approaches and in-house flow network models 3-D computational fluid dynamics Developing and documenting methods to analyze core thermal-hydraulic behavior at steady-state and during transients Automation, verification, and validation of modeling and simulation tools in support of analyses Collaborating cross-functionally to define design requirements, and providing technical feedback to quick-iterating design teams Minimum Qualifications Bachelors, Masters, or PhD in a technical field, such as nuclear, mechanical, or aerospace engineering Proficiency with thermal fluids (thermal-hydraulics) analysis methods and first principles Able to write clear and concise documentation Experience with low-fidelity and intermediate-fidelity (e.g., porous body and correlation-based) models for heat transfer and fluid flow numerical methods and software development for heat transfer and fluid flow problems data processing (e.g., pre-processing, post-processing, scripting) Bonus Qualifications Fluency with Python Demonstrated success in qualification and validation of analyses
