About this role
Lead Engineer for TerraPower's Natrium Demonstration Project, responsible for designing and delivering the Reactor Air Cooling System (RAC). You will champion integrated decay heat removal analysis and drive thermal hydraulics validation for a first-of-a-kind advanced sodium-cooled fast reactor moving toward commercial deployment.
Responsibilities
- Lead development and execution of thermal hydraulics analyses for reactor systems, including steady-state, transient, and accident/off-normal condition evaluation
- Integrate testing and validation methods into system fluid thermal models and develop multi-disciplinary margin evaluations
- Lead and author topical reports for licensing applications
- Serve as central integrator of thermal hydraulics results across internal engineering teams, suppliers, national labs, and research partners
- Drive alignment across multidisciplinary engineering teams (nuclear, thermal hydraulic, mechanical, instrumentation and controls, civil-structural) to define and refine system requirements
- Establish and maintain the thermal hydraulics analysis basis, including assumptions, methodologies, and acceptance criteria
- Ensure consistency of boundary conditions, inputs, and assumptions across models and organizations
- Resolve discrepancies between analyses and drive convergence toward unified, defensible system response
- Manage technical interfaces with suppliers and review/verify deliverables
- Prepare complete analysis packages addressing all relevant phenomena to ensure nuclear safety
- Ensure verification and validation of analysis methods, including biased safety-related modeling techniques
- Integrate application-dependent modeling tools to support safety, PRA, and component design applications
- Perform independent verifications of models and software tools
- Evaluate technology development requirements and implement development programs for novel approaches
- Interface with and support licensing activities for construction and operating licenses
- Participate in project design reviews at milestones to verify compliance and completeness
- Provide subject matter expertise on fluid flow, heat transfer, two-phase flow, and reactor system response
Preferred qualifications
- Previous experience with nuclear reactors and systems, high temperature pressure vessels, or similar system design
- General or working knowledge of ASME BPVC Section III
- Professional engineering licensure
- Experience originating and developing technical documentation to support system architecture
- Advanced degree in relevant discipline
