Reactor Systems Engineer

About the role

Ocean Atomics is an American company designing, licensing, and assembling a standardized nuclear electric power plant and the surrounding support systems for maritime applications. The Reactor Systems Engineer will define the arrangement of the primary system, build and run system-level thermal-hydraulic models, and design and analyze the system architecture across normal, transient, and accident conditions.

Responsibilities

• Define and maintain the arrangement of the primary system and its interfaces with supporting systems
• Build, run, and maintain system thermal-hydraulic models spanning steady-state, transient, and accident scenarios
• Design and analyze decay heat removal architectures and demonstrate adequate cooling for limiting events, leveraging the maritime environment as appropriate
• Support trade studies that balance arrangement, component sizing, and safety margins
• Rigorously document analysis results and justify methodology and V&V in support of the licensing process
• Couple system models with neutronics and structural inputs to support multiphysics and transient studies
• Provide primary system and accident-response information to safety analysis, simulator, and operations teams

Requirements

• Experience building and running system thermal-hydraulic models of nuclear plants
• Strong understanding of primary system behavior, including natural circulation, two-phase flow, and the design tradeoffs between active and passive cooling
• Working knowledge of decay heat removal design and the design basis events that size it
• Strong working knowledge of one or more reactor systems codes (e.g. RELAP5-3D, TRACE)
• Ability to work on a close, rapidly iterative design team and translate analysis into arrangement decisions
• Strong technical writing skills

Qualifications

• Bachelor's degree in Nuclear or Mechanical Engineering
• 5+ years designing or analyzing reactor primary systems
• Familiarity with multiple system and subchannel/CFD tools (e.g. RELAP5-3D, TRACE, GOTHIC, COBRA, STAR-CCM+)
• Familiarity with coupling system models to neutronics
• Experience supporting safety analysis and licensing basis development (DBAs, LOCA/non-LOCA, station blackout)
