Plant Integrated Analysis Engineer

Overview:
System One is seeking a highly capable and motivated Plant Integrated Analysis Engineer to support advanced nuclear reactor development within a sodium-cooled reactor program. This role focuses on plant-level thermal-hydraulic and control system analysis, supporting design, safety, and operational performance.

This is a highly technical role working cross-functionally with safety, I&C, and design engineering teams to model, analyze, and validate complex plant systems.

Responsibilities:

• Develop RELAP5-3D models for steady-state and transient one-dimensional hydraulic network analyses
• Perform plant-level thermal-hydraulic analysis for normal operations, upset conditions, and emergency scenarios
• Develop and evaluate plant control strategies and component-level controllers
• Perform first-principles calculations (heat transfer, fluid dynamics, thermodynamics) to support analysis results
• Analyze plant-wide transients to support operational strategies and design improvements
• Conduct multi-scale, multidisciplinary analyses involving sodium, molten salt, and non-condensable fluids
• Collaborate with engineering teams across system, component, fuel, and control system design
• Support development of analytical methods and validation of modeling approaches

Required Qualifications:

• B.S. or higher in Nuclear, Mechanical, or Electrical Engineering
• Experience with system codes such as RELAP5 or TRACE (required)
• Strong thermal-hydraulic analysis experience, including one-dimensional hydraulic networks and transient analysis
• Strong technical writing and communication skills

Preferred Qualifications:

• Experience modeling control systems and I&C
• Background in nuclear power plant design or operations
• Experience developing new analytical methods

Additional Details:

• Travel: 0-5%
• Work Environment: Primarily remote, standard office setting
• Physical Requirements: Minimal (ability to sit/stand for extended periods, lift up to 25 lbs as needed)
