  • Develop plant-level control strategies and component-level controllers
  • Perform calculations using first principles of heat transfer, thermodynamics, and fluid dynamics to validate analytical results
  • Support evaluation of plant-wide transients, operational narratives, and design solutions
  • Perform multiscale and multidisciplinary thermal hydraulic analyses involving sodium, molten salt, and non-condensable fluids
  • Collaborate closely with safety, I&C, design engineering, and testing teams
  • Support development of new analytical methods and advanced modeling techniques
  • Prepare technical reports, calculations, and engineering documentation
