Computational Thermal-Hydraulics Engineer
About The Position
The Reactor Systems and Heat Transport department at Idaho National Laboratory (INL) is seeking a highly motivated Computational Thermal-Hydraulics Engineer to support advanced modeling and simulation efforts for nuclear energy systems at our Idaho Falls, Idaho location. Our team works a 9/80 schedule with every other Friday off. This position focuses on high-fidelity computational fluid dynamics (CFD), thermal-hydraulics, and verification and validation (V&V) of simulation tools and experimental benchmarks. The successful candidate will contribute to national and international collaborative efforts, supporting the development of next-generation nuclear technologies.
Requirements
- Bachelor of Science in Nuclear Engineering or directly related engineering degree from an ABET-accredited institution and (2) years of related experience or Master’s degree in Nuclear Engineering or closely related field from an ABET-accredited institution.
Nice To Haves
- Ph.D. in Nuclear Engineering or a closely related field from an ABET-accredited institution.
- Hands-on experience with CFD tools such as STAR-CCM+ and nekRS.
- Knowledge of high-fidelity simulation methods (LES, DNS).
- Experience with V&V methodologies and benchmarking of experimental facilities.
- Familiarity with NEAMS thermal-hydraulic modeling tools.
- Understanding of natural convection and radiative heat transfer in nuclear systems.
- Experience with dry cask storage modeling and re-criticality simulations.
- Proficiency in programming languages such as Python, C++, or FORTRAN for data processing and automation.
- Familiarity with high-temperature gas-cooled reactors and advanced reactor concepts.
Responsibilities
- Develop and execute CFD models using tools such as STAR-CCM+ and nekRS for thermal-hydraulic analysis.
- Perform high-fidelity simulations including Large Eddy Simulations (LES) and Direct Numerical Simulations (DNS).
- Conduct benchmarking and validation studies using experimental data from national and international facilities.
- Support verification and validation (V&V) activities for independent analysis and regulatory-grade assessments.
- Analyze and compare simulation results across multiple institutions and tools to identify trends and discrepancies.
- Apply NEAMS tools for thermal-hydraulic modeling and analysis of nuclear systems.
- Model natural convection systems, including radiative heat transfer effects.
- Prepare technical reports, peer-reviewed publications, and presentations for sponsors and conferences.
- Collaborate with multidisciplinary teams including experimentalists, analysts, and software developers.
