Core Thermal-Hydraulics Engineer

The ocean is the largest undeveloped frontier on earth and the next chapter of abundant energy will be written at sea. Were building the infrastructure to power it.

Ocean Atomics is an American company designing licensing and assembling a standardized nuclear electric power plant and the surrounding support systems for maritime applications. We will install these plants on any vessel built to our nuclear-ready standards and will provide end-to-end sustainment in our planned nuclear lifecycle dockyard. We will help develop the licensed operators to unlock this new capability for your energy intensive application at sea. To move fast and to lead the creation of this new market we are leveraging the compact proven systems enabled by water-cooled reactors.

Scale nuclear energy. Power generations.

A maritime commons thriving with abundant economical modern and safe nuclear-powered activity built serviced and staffed by re-industrialized American shipyards and people.

The Core Thermal-Hydraulics engineer performs design and analysis of coolant flowing through the core primary systems and safety systems under normal and transient conditions. This role is foundational to the reactor systems design and the effects of ship motions and ship-driven space constraints demand uncommon levels of innovation and skill.

• Design and analyze coolant flow through the core and primary systems evaluating pressure drop flow distribution mixing and heat transfer to optimize performance.

• Develop and refine thermal-hydraulic analysis methods models and correlations (e.g. subchannel system and CFD analyses) to support core and primary system design.

• Establish thermal margins and operating limits (e.g. DNBR flow-induced effects) and feed results into design and safety analyses.

• Partner with the testing team to prioritize test campaigns define instrumentation and conditions and target the data most valuable to the design.

• Incorporate test data into analytical models via validating calibrating and benchmarking to reduce uncertainty and improve design fidelity.

• Bachelors degree in nuclear or mechanical engineering required (advanced degree preferred).

• Experience in reactor thermal/hydraulic design and analysis.

• Proficiency with thermal/hydraulic and/or CFD codes (e.g. COBRA VIPRE STAR-CCM or equivalent).

• Strong grounding in fluid mechanics heat transfer and two-phase flow.

• Experience integrating experimental or test data into analytical models.

Export control notice

This role involves access to information subject to U.S. export control laws including unclassified nuclear technology governed by the U.S. Department of Energy under 10 CFR Part 810. Depending on a candidates status access may require DOE authorization which Ocean Atomics may apply for. Any offer is contingent on your ability to work in compliance with these requirements. We evaluate all applicants regardless of citizenship or national origin except where required by law.

Every industry on Earth needs scalable clean energy and the ocean is the ideal place to unlock it. Joining Ocean Atomics means building real lasting infrastructure the kind that powers generations. The world needs abundant energy. Lets make it happen.
