This role focuses on structural analysis, FEA-based evaluations, degradation assessments, and mechanical support for aging management programs. It blends mechanical design, analysis, FEA, and problem-solving.

Candidates should have strong mechanical analytical skills, experience evaluating loads and stresses on components, and an interest in complex mechanical systems within operating nuclear plants.

Primary Responsibilities:

• Mechanical and Structural Analysis
  • Perform mechanical and structural evaluations for reactor internals, vessel components, and pressure boundary hardware.
  • Participate in evaluations of mechanical degradation including fatigue, cracking, wear, or thermal-mechanical aging.
  • Review engineering drawings, specifications, and inspection data to support mechanical integrity decisions.
• Component and System Evaluation
  • Support design or redesign of mechanical components, incorporating operational load conditions and aging effects.
  • Participate in evaluations for equipment modifications, upgrades, or corrective actions.
  • Support emergent outage work including root-cause evaluations, foreign material assessments, or mechanical damage investigations.
• Project Execution and Reporting
  • Prepare technical reports, drawings packages, analyses, and calculation files with nuclear-grade quality.
  • Collaborate with cross-functional teams (materials, chemistry, FEA, piping) to develop integrated solutions.
• Client Engagement & Business Development
  • Contribute to proposals, scopes, estimates; identify growth opportunities
• Collaboration & R&D
  • Collaborate across disciplines; contribute to internal R&D roadmap and industry activities (e.g., EPRI participation, method improvements).

• B.S. or M.S. in Mechanical Engineering or related discipline.
• 4–10 years of mechanical engineering experience (preferably power/nuclear or similar heavy industry).
• Experience with FEA (ANSYS, Abaqus, SolidWorks Simulation, or similar).
• Experience evaluating structural loads, mechanical components, and degradation.
• Strong technical writing and communication skills.
• Ability to support multiple concurrent engineering tasks.

Desired Skills/Qualifications:

• Exposure to nuclear mechanical assessments, ASME Code rules, or reactor internals evaluations.
• Background in fatigue analysis, fracture mechanics input prep, or thermal-mechanical load assessment.
• Experience with CAD/3D modeling (SolidWorks, Inventor) and data analytics.
• Familiarity with aging management, inspection programs, or system modifications.
