Responsibilities
- Own methods development strategy for thermal-hydraulic safety analysis supporting PWR uprates, including evaluation-model approach, analysis scope, acceptance criteria, sensitivity strategy, uncertainty treatment, and interpretation of results.
- Assess Alva's analysis toolbox and help determine where existing methods are sufficient, where they require extension or validation, and where new methods or workflows should be developed.
- Develop, modify, review, and technically direct models using one or more nuclear safety analysis codes such as RELAP5, RETRAN, VIPRE, GOTHIC, TRACE, COBRA, SIMULATE, or equivalent tools.
- Lead verification, validation, calibration, and benchmarking of models and methods against plant data, test data, vendor information, prior analyses, and code-to-code comparisons; investigate discrepancies and identify the underlying physical or modeling cause.
- Develop defensible approaches to uncertainty, conservatism, scaling, stability, sensitivity, and margin assessment, with particular focus on distinguishing physical limitations from methodological limitations.
Requirements
- Bachelor's degree in Nuclear, Mechanical, Chemical Engineering, or a related technical field
