Senior Engineer, Fuel Performance

• Perform thermo-mechanical analysis of fuel rods and other sodium fast reactor core components to support core/plant design activities, irradiation testing, and code benchmarking
• Work with interdisciplinary team of engineers to ensure fuel and absorber designs meet their overall objectives
• Develop fuel and material models and analysis methods
• Compose and review technical documents to support core/reactor plant design, licensing, software verification and validation, and testing activities
• Design and execute sensitivity studies to understand the effects and validity of various modeling assumptions, including meshing, physics coupling, material models, design tolerances
• Development of software and databases for cataloging experiments and analysis
• Create formal documentation of nuclear fuels methods software requirements, design, implementation, and testing in support of licensing reactors.
• Update, improve, and/or create software to satisfy all licensing requirements during the Verification and Validation (V&V) process
• Support software and document reviews in areas of fuel performance modeling, fuel performance, or other areas of subject expertise
• Build and apply methods to assess the propagation of uncertainty and their effect on safety margins
• Enhance engineering team's ability to build models and make meaningful conclusions from simulation output through input tools, visualization, reports, etc.
• Support irradiation testing by performing fuel performance assessments for pre-test predictions or support interpretation of test results, prepare test plans, and prepare test reports summarizing results
