- Proficiency with thermal-hydraulics (thermal fluids) analysis methods
- Core competencies in heat transfer, fluid dynamics, and thermodynamics first principles
- Experience with intermediate-fidelity (e.g., porous body and correlation-based) models for heat transfer and fluid flow
- Experience with numerical methods for heat transfer and fluid flow problems
- Experience with data processing (e.g., pre-processing, post-processing, scripting)
Requirements
- Fluency with Python
- Experience with CI/CD computing environments
- Experience with reactor systems codes, such as SAS4A/SASSYS-1, SAM, RELAP, TRACE, or GOTHIC
- Experience with qualification and validation of analyses
- Experience with subchannel analysis codes, such as DASSH, MOOSE-Subchannel, COBRA-TF, or similar
- Experience with high-fidelity fluid dynamics analysis
