Position Overview:

The R&D Nuclear Fuel Performance Engineer will support the design, analysis, and optimization of nuclear fuel systems by leveraging advanced multiphysics computational tools such as INL's MOOSE/BISON. The role involves developing BWXT's fuel performance code set(s) predictive capabilities in evaluating fuel behavior under normal and off-normal conditions, and contributing to the engineering basis for licensing, fabrication, and operational decision-making. This position requires strong technical proficiency, analytical thinking, and the ability to collaborate across multi-disciplinary teams in materials engineering, reactor physics, and thermal-hydraulics.

Location:

Remote or on-site at the BWXT Innovation Campus site in Lynchburg, VA.

Your Day to Day as an R&D Nuclear Engineer - Fuel Performance:

• Execute detailed fuel performance simulations using MOOSE/BISON and related frameworks to evaluate thermo-mechanical response, fission gas behavior, cladding deformation, and irradiation-driven material evolution.
• Support R&D-driven fuel design activities by integrating experimental data, advanced material models, and irradiation physics into engineering decisions.
• Develop and refine constitutive models for fuel and cladding materials, including creep, plasticity, swelling, phase transformations, and high-temperature mechanical behavior.
• Analyze irradiation test results, PIE datasets, microstructural characterization, and thermophysical measurements to calibrate, validate, and improve fuel performance codes.
• Contribute to the design and evaluation of new fuel forms (e.g., ATF concepts, metallic fuels, composite claddings, advanced ceramics).
• Collaborate closely with reactor physicists, thermohydraulic analysts, materials scientists, fabrication engineers, and licensing specialists.
• Prepare technical analyses, R&D reports, and simulation documentation for internal use and regulatory interfaces.
• Maintain high-quality modeling workflows and support verification, validation, and uncertainty quantification activities.

Required Qualifications:

• A Bachelor's degree in Engineering or…
