Maritime Reactor Core Mechanical Engineer

Ocean Atomics; Bethesda (MD); On-site; USD 120,000 - 190,000; Full time

Job summary

Ocean Atomics LLC is seeking a Reactor Core Mechanical Engineer to design and analyze the mechanical components and internals of a maritime nuclear reactor core. The role focuses on flow-induced vibration, ship motions, and shock loading to ensure structural integrity across the core's service life on sea-going platforms.

You'll collaborate with thermal-hydraulics, fuels, and structural teams, document analyses and qualification results, and contribute to the development of nuclear-enabled

Qualifications

• Bachelor's degree in mechanical or nuclear engineering; 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).
• 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).

Responsibilities

• 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.
• Coordinate 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.
