Reactor Core Mechanical Engineer

Role Summary

As Reactor Core Mechanical Engineer, you design and analyze the mechanical components and internals of the reactor core, with a focus on what changes when a reactor operates on a vessel at sea. Flow-induced vibration, ship motions, and shock loading reshape structural integrity implications across the core's service life. Your analysis is what separates a reactor designed for a fixed foundation from one engineered to operate reliably in maritime conditions.

What You'll Do

• Design and analyze core mechanical components and internals for structural integrity, fatigue, and wear across operating, transient, and accident conditions.
• Evaluate flow-induced vibration of fuel assemblies, control elements, and internals, and develop design features to mitigate wear and dynamic effects.
• Assess the effects of ship motions and dynamic/shock loading on core mechanical performance and structural margins.
• Coincide with thermal-hydraulics, fuels, and structural teams to integrate mechanical design with flow, thermal, and neutronic requirements.
• Document mechanical analyses, design basis, and qualification results, and support design reviews and testing.

What You Bring

• Bachelor's degree in mechanical or nuclear engineering required (advanced degree preferred).
• Experience in mechanical design and structural analysis of reactor core components or internals.
• Proficiency with finite element analysis and structural/vibration tools (e.g., ANSYS, ABAQUS, or equivalent).
• Working knowledge of flow-induced vibration, fatigue, and dynamic/shock loading analysis.
• Strong grounding in solid mechanics, materials behavior, and structural dynamics.
• Understanding of naval architecture and marine engineering (preferred).
