Plant Integrated Analysis Engineer

About the role

The Plant Integrated Analysis Engineer supports the development of advanced sodium-cooled nuclear reactor technology. This role focuses on plant-level thermal-hydraulic analysis, transient modeling, and control system performance to support reactor design, safety, and operational excellence.

Responsibilities

• Develop and maintain RELAP5-3D models for steady-state and transient one-dimensional hydraulic network analyses.
• Perform plant-level thermal-hydraulic analyses for normal operating conditions, upset events, and emergency scenarios.
• Develop, evaluate, and optimize plant control strategies and component-level control systems.
• Perform first-principles engineering calculations involving heat transfer, fluid dynamics, and thermodynamics.
• Analyze plant-wide transients to support operational strategies and reactor design improvements.
• Conduct multidisciplinary analyses involving sodium, molten salt, and non-condensable fluid systems.
• Collaborate with system, component, fuel, safety, and I&C engineering teams.
• Support the development, validation, and improvement of analytical methods and modeling approaches.
• Prepare technical documentation and communicate analysis results to cross-functional engineering teams.

Requirements

• Bachelor's degree or higher in Nuclear Engineering, Mechanical Engineering, Electrical Engineering, or a related engineering discipline.
• Experience using thermal-hydraulic system analysis codes such as RELAP5 or TRACE.
• Strong experience performing one-dimensional hydraulic network and transient thermal-hydraulic analyses.
• Solid understanding of heat transfer, fluid mechanics, and thermodynamics.
• Excellent analytical, technical writing, and communication skills.

Preferred Qualifications

• Experience modeling plant control systems and Instrumentation & Controls (I&C).
• Background supporting commercial or advanced nuclear power plant design or operations.
• Experience developing or improving analytical methods and engineering models.
• Experience working within a highly regulated engineering environment.
