About The Position

The Nuclear Engineer 4 reports to the Manager, Nuclear Design and works collaboratively with Thermal Hydraulics, Code Development, and Nuclear Methods teams within the broader Nuclear Fuels department, as well as with other Engineering, Licensing, and Plant Operations disciplines. This position is an experienced engineer that provides technical leadership and hands‑on delivery across core and fuel design and analysis, application of licensed methods to reload analysis, and at operations interfaces including reactor engineering, start‑up physics, and core monitoring. Practical knowledge of and experience with PWR reactor physics analyses is critical.

Requirements

• A minimum of B.S. degree in Nuclear, Mechanical, or Chemical Engineering (or related discipline) from a four-year accredited college or university is required.
• A minimum of 8 years of full-time, directly relevant engineering experience is required.
• Demonstrated experience in implementing engineering design processes for core design, neutronics, reactor engineering, and related safety analysis is required.
• Eligible to work under Department of Energy 10 CFR Part 810.

Nice To Haves

• An M.S. in Nuclear, Mechanical, or Chemical Engineering is desirable.
• Experience in fuel design or fuel performance preferred.

Responsibilities

• Perform core design and neutronics analysis for cycle design and reloads, including lattice physics generation, core loading optimization, and safety‑related physics inputs to engineering design and analysis interfaces and licensing.
• Prepare core monitoring inputs, COLR inputs, and other technical information for operations support. Translate method limits, assumptions, and uncertainties into practical guidance for plant engineering and operations.
• Configure, validate, and maintain core monitoring software models and inputs, ensuring reliable online core follow, margin tracking, and surveillance alignment with Technical Specifications.
• Design, analyze, and support deployment of neutron source assemblies, including mechanical and neutronics evaluations, integration with monitoring instrumentation, control of physical design interfaces, and strategy development for plant deployments.
• Exercise in-depth knowledge of industry best-practices and state-of-the-art advancements to continue to assess design and licensing basis and identify risks, challenges, and opportunities with the established design and methods.
• Ensure alignment and integration of licensed methods with application to services to customers and other end users.
• Provide technical leadership within Nuclear Design; design scope and direct complex analysis tasks in areas of expertise and mentor junior engineers.
• Prepare and verify engineering reports, calculations, studies, system descriptions, requirement specifications, and other design documents. Work on tasks in multiple and diverse areas.
• Support development and maintenance of licensed nuclear design methods and associated implementing analyses.
• Work collaboratively within Nuclear Fuels and among the Engineering organization to ensure design and analysis interfaces are adequately managed. Align analysis milestones with operations schedules, outage windows, and reload execution plans.
• Communicate professionally in areas of technical responsibility across disciplines, at various levels of the organization, and with internal and external stakeholders including customers and regulatory bodies.
• Develop innovative solutions to multifaceted technical challenges requiring original thinking, multi‑physics reasoning, and the ability to navigate uncertainty. Independently frame problems, propose solution strategies, and execute analyses with minimal oversight.
• Perform other duties as assigned. Flexibly support changing organizational priorities, including urgent analysis needs, cross‑functional reviews, technical troubleshooting, or special studies.
