Original job description

Job Title: Principal Reactor Fuel Engineer Location: Oak Ridge, TN (Relocation Offered) Type: Direct Hire Compensation: $255,000 Work Model: Hybrid

Responsibilities

Develop and maintain the KRONOS Fuel Qualification Statistics and Uncertainty Quantification Plan, including confidence requirements, acceptance probabilities, decision rules, and concurrence points.
Establish defensible sample sizes and population definitions for kernels, TRISO particles, ceramic pellets, manufacturing lots, irradiation specimens, PIE populations, and safety-test specimens.
Develop methods for estimating defect, particle-failure, fuel-failure, and fission-product-release fractions, including zero-failure and censored datasets.
Establish uncertainty budgets covering characterization, irradiation conditions, PIE measurements, material properties, safety testing, and derived qualification parameters.
Define statistical requirements for model calibration and validation, bias evaluation, sensitivity analysis, uncertainty propagation, applicability limits, and experimental comparison.
Develop design-of-experiments, process-capability, variability, sampling, and acceptance methods supporting repeatable production-intent fuel.
Evaluate data exclusions, outliers, missing data, anomalous observations, and extrapolations.
Author clear statistical conclusions and uncertainty statements supporting fuel qualification and licensing documentation.

Requirements

Advanced degree in Statistics, Applied Mathematics, Reliability Engineering, Nuclear Engineering, Materials Science, or a closely related quantitative discipline.
5+ years supporting nuclear fuel, materials qualification, reliability, manufacturing qualification, model validation, or another safety-critical technical program.
Expertise in design of experiments, acceptance sampling, uncertainty propagation, reliability methods, statistical inference, and model calibration or validation.
Experience developing statistical approaches before data collection and working with sparse, censored, zero-failure, or heterogeneous datasets.
Proficiency with controlled statistical-computing workflows and rigorous documentation of calculations, software, data transformations, assumptions, and independent reviews.
Strong technical writing and communication skills, including the ability to translate statistical limitations into clear engineering, safety, and regulatory conclusions.
Direct experience with TRISO, advanced nuclear fuel, or high-temperature ceramic qualification.
Experience estimating low-probability defect or failure fractions at regulator-relevant confidence levels.
Familiarity with ASME NQA-1, nuclear software QA, configuration control, and regulator-facing technical reports.
Experience integrating manufacturing process capability, experimental uncertainty, and model-form uncertainty into qualification decisions.
