Senior FEA Analyst - Nuclear Fuel Behavior & Operations

Job Description Protingent Staffing has an exciting direct hire Senior FEA Analyst – Nuclear Fuel Behavior & Operations opportunity. Position Title Senior FEA Analyst – Nuclear Fuel Behavior & Operations Position Description Protingent Staffing has an exciting direct hire Senior FEA Analyst – Nuclear Fuel Behavior & Operations opportunity. Job Responsibilities Multi-Physics Fuel Modeling: Develop and execute high-fidelity 2D and 3D finite element models to simulate the coupled thermo-mechanical behavior of fuel rods, pellets, and cladding under steady-state, transient, and accident scenarios (RIA/LOCA). Interface & Interaction Analysis: Conduct detailed evaluations of Pellet-Cladding Mechanical Interactions (PCMI) and Pellet-Cladding Thermal Interactions (PCTI), capturing localized stress concentrations, mechanical locking, and cladding strain. Microstructural Performance Integration: Simulate time- and burnup-dependent fuel phenomena, including fission gas release, fuel swelling, densification, thermal conductivity degradation, and cladding creep/hydriding. Code Application & Customization: Utilize and adapt state-of-the-art nuclear fuel performance codes (e.g., BISON, FRAPCON/FRAPTRAN, ENIGMA) alongside commercial solvers to predict fuel life-cycle behavior. V&V and Quality Assurance: Lead rigorous Verification and Validation (V&V) procedures for fuel performance models in strict compliance with ASME NQA-1 quality standards. Regulatory Technical Support: Compile, review, and authorize formal technical reports and licensing topical reports to defend fuel safety margins before nuclear regulatory authorities (e.g., US NRC). Job Qualifications Education: Master’s or Ph.D. degree in Nuclear Engineering, Materials Science, Mechanical Engineering, or a highly relevant engineering discipline. Experience: Minimum of 5–8+ years of experience in computational mechanics, with at least 3 years dedicated specifically to nuclear fuel performance modeling or core materials evaluation. Software & Code Expertise: Advanced proficiency with nuclear fuel burnup and performance codes (specifically BISON or FRAPCON), paired with commercial implicit solvers (Abaqus or ANSYS Mechanical). Core Competencies: Deep understanding of high-temperature material science, radiation effects on materials (swelling, creep), and fracture mechanics. Proven capability in scripting and code customization (Python, C++, or Fortran) to automate workflows and implement custom material subroutines. Familiarity working within rigid nuclear quality assurance frameworks (NQA-1). Preferred Job Qualifications Experience modeling advanced technology fuels, such as Accident Tolerant Fuel (ATF) concepts, doped UO2, silicide fuels, or liquid metal/molten salt reactor fuel elements. Active or prior U.S. DOE Q-Level or DoD Secret security clearance. Strong track record of publishing peer-reviewed research or presenting technical findings to nuclear regulatory bodies.
