Job description

The CFD Engineer Specialist will support engineering and licensing requirements, leading to the licensing and construction of the first SMR-300 plant. The engineer will use, and have the opportunity to learn, various methods and software to perform the analyses. The Engineer will be part of a team executing a U.S. Government cost-shared development program requiring the efficient completion of engineering assignments, including coordination with other engineers in U.S. and offshore operating centers.
Location: Camden, NJ (On-site)
Primary Responsibilities:
  • Develop new and innovative Computational Fluid Dynamics (CFD) simulations related to nuclear power plant components.
  • Collaborate in small teams focused on the development and execution of complex multi-physics flow simulations, including conjugate heat transfer.
  • Apply developed and developing capabilities to directly impact design processes and minimize the need for hardware testing.
  • Provide actionable component-level and/or system-level design recommendations to Design Responsible Engineers by interpreting complex analysis results.
  • Participate in product design and development teams, presenting analysis results to engineering peers and management.
  • Enhance concept designs based on limited requirements or functions and develop mature requirements by gaining an understanding of the system, structure, or components.
  • Transform concept designs into license ready designs through critical thinking, literature research, collaboration with team members from other disciplines and vendors, and any analysis permitted by project milestones.
  • Support the preparation of design deliverables, presentations, and communicate design progress in stakeholder meetings.
  • Author and review technical reports, calculation packages, and licensing documentation in compliance with NQA-1 and NRC regulatory frameworks (e.g., RG 1.203) to support the reactor's Preliminary and Final Safety Analysis Reports (PSAR/FSAR).

Requirements:
  • Advanced degree in Mechanical or Nuclear Engineering with a focus on thermal-hydraulic analysis and design
  • 5+ years of experience in CFD and thermal-hydraulics
  • Proficient in ANSYS (Fluent, CFX, Workbench), STAR-CCM+, meshing tools, and SpaceClaim
  • Strong knowledge of heat transfer, fluid dynamics, and CFD turbulence models
  • Familiarity with two-phase flow modeling
  • Programming skills in Python, C++, or Java for automation and post-processing
  • Excellent analytical, problem-solving, and computer skills
  • Strong technical writing, communication, and organizational abilities
  • Detail-oriented with a focus on accuracy and error-free work
  • Eligible to work under 10 CFR Part 810
  • MS or PhD in Mechanical Engineering, applied mechanics, or closely related field of engineering (preferred).
  • Industry experience using CFD simulation to support product development.
  • Experience working with engineers and fabricators to develop designs and drawings.
  • Experience with SolidWorks, AutoCAD, and ANSYS software.
  • Knowledge of ASME Section III compliance and NRC regulatory frameworks for code validation is a major plus.
  • Experience working in the nuclear industry.
