About the Role We are seeking a Nuclear Thermal Hydraulics Engineer specializing in thermal-hydraulics to support the design and analysis of advanced reactor systems. The successful candidate will develop, implement, and validate models to assess heat transfer, fluid flow, and system performance under steady state and transient conditions.
Key Responsibilities- Perform thermal-hydraulic and system-level analyses for reactor designs.
- Develop models using codes such as RELAP5, TRACE, OpenFOAM, COMSOL, or ANSYS Fluent.
- Analyze heat transfer, flow distribution, and two-phase flow phenomena.
- Support safety and performance assessments through coupled neutronic-thermal simulations.
- Evaluate coolant system design and decay heat removal capabilities.
- Prepare technical reports and present analysis results to project teams and stakeholders.
- Support the business development activities of the company including proposals, RFPs, regulatory applications, and other as needed.
Qualifications- Bachelor's, Master's, or Ph.D. in Nuclear Engineering, Mechanical Engineering, or related discipline.
- 2+ years of relevant experience in thermal-hydraulics analysis (industry, research, or graduate work).
- Demonstrated proficiency in one or more of the following: RELAP5, TRACE, OpenFOAM, ANSYS Fluent, COMSOL, or equivalent CFD/system codes.
- Strong understanding of heat transfer, single- and two-phase flow, and reactor cooling systems.
- Experience with Python, MATLAB, or similar scripting tools for post-processing and data automation.
- Excellent analytical and communication skills, including strong writing skills.
- Experience with CFD coupling, or multi-physics simulation.
- Exposure to experimental validation or test loop design.
- Prior experience with Aerospace or Military Grade engineering is a plus.
