Job Summary

Lead high-fidelity finite element and multi-physics computational modeling to evaluate nuclear fuel assemblies and core components. Model thermo-mechanical behavior of fuel rods, pellet-cladding interactions, and long-term degradation across steady-state, transient, and accident scenarios. Apply and customize nuclear fuel performance codes (e.g., BISON, FRAPCON/FRAPTRAN, ENIGMA), run verification/validation to ASME NQA-1, and produce licensing-ready technical reports supporting US NRC safety margins.

Location: Austin

Workplace: Onsite

Employment Type: Full time

Job Function: Administration & Executive Assistance

Seniority: Mid level

Key Responsibilities

•Develop and execute high-fidelity 2D/3D finite element models for fuel rods, pellets, and cladding under steady-state, transient, and accident scenarios.
•Analyze pellet-cladding mechanical and thermal interactions, including stress concentrations, mechanical locking, and cladding strain.
•Integrate time- and burnup-dependent fuel phenomena such as fission gas release, fuel swelling, densification, thermal conductivity degradation, and cladding creep/hydriding.
•Apply and customize nuclear fuel performance codes and commercial solvers to predict fuel life-cycle behavior.
•Lead V&V and produce/authorize formal technical and licensing topical reports to defend fuel safety margins before nuclear regulatory authorities.

Pay and Benefits

Salary: USD 125,000 annually

Perks:Health InsuranceDentalVisionPaid LeaveGym Membership

Key Requirements

•Master’s or Ph.D. in Nuclear Engineering, Materials Science, Mechanical Engineering, or a closely related field.
•5–8+ years in computational mechanics, including at least 3 years focused on nuclear fuel performance modeling or core materials evaluation.
•Advanced proficiency with nuclear fuel burnup/performance codes, specifically BISON or FRAPCON.
•Experience using commercial implicit solvers such as Abaqus or ANSYS Mechanical.
•Ability to script and customize code/workflows (Python, C++, or Fortran) and familiarity with NQA-1 nuclear quality assurance frameworks.
