Fuels Engineer

This is a fully remote position, open to applicants in United States.

📋 Description

• Assist in the design, analysis, and development of the nuclear fuel system for the next-generation reactor.

• Assess commercial fuel designs and conduct fuel performance modeling.

• Evaluate material behavior under irradiation and aid in the integration of fuel into the reactor core design.

• Collaborate with external fuel suppliers and convert commercial fuel design data into internal models and design choices.

• Contribute to reactor fuel system design, including aspects such as fuel form, geometry, cladding, and standard assembly configurations.

• Analyze thermal and mechanical behavior of fuel, focusing on pellet-clad interaction, fission gas release, swelling, densification, creep, corrosion, and cladding oxidation.

• Examine fuel performance under steady-state, transient, and accident scenarios.

• Coordinate with fuel suppliers regarding design data, fabrication limitations, tolerances, and irradiation performance.

• Construct and execute fuel performance models utilizing tools like BISON, FRAPCON/FRAPTRAN, FAST, Falcon, or comparable software.

• Analyze fuel burnup, isotopic depletion, fuel cycle duration, and end-of-life behavior.

• Validate and benchmark models while supporting Verification & Validation initiatives.

• Characterize cladding and structural materials while assessing mechanical limits.

• Assist in materials qualification and irradiation test campaigns.

• Help develop test plans, irradiation capsules, and conduct post-irradiation examination.

• Collect and analyze data from national laboratories, testing facilities, and suppliers.

• Create technical reports and documentation for design decisions, integration reviews, and licensing support.

• Collaborate with teams focused on neutronics, thermal-hydraulics, mechanical, thermal-fluids, and reactor design.

• Support trade studies regarding enrichment, burnup, cladding options, and fabrication methods.

• Take full responsibility for projects from initial concepts through to deployment and operations.

• Enhance internal engineering processes, documentation, and tools.

⛳️ Requirements

• Bachelor’s degree in Nuclear Engineering or a related discipline.

• Over 4 years of relevant industry experience.

• Experience with nuclear fuel behavior and/or material science under irradiation.

• Familiarity with tools related to fuel performance or nuclear materials (BISON, FRAPTRAN, MOOSE, FAST, or similar).

• Understanding of neutronics and thermal-hydraulics principles concerning fuel performance.

• Exceptional analytical, communication, and documentation abilities.

• Self-motivated individual who thrives in a fast-paced, hardware-centric environment.

• Visa sponsorship is not available.

• Ability to comply with U.S. export control regulations.

🏝️ Benefits

• Significant incentive stock plan available for all full-time employees.

• Medical, Vision, and Dental coverage (details to be provided later).

• Flexible Paid Time Off (PTO) policy.

• Options for hybrid and remote work depending on the role.

• Additional benefits to be disclosed at the offer stage.
