Senior Engineer, Thermal Hydraulic Analyses

Job Description Summary
This role is instrumental in advancing our nuclear thermal-hydraulic capabilities, with a particular focus on supporting fuel development and the associated system / subchannel analysis codes. The position requires a dynamic thermal-hydraulic engineer with expertise in core and fuel thermal-hydraulic analysis and methods development. Key responsibilities include developing and optimizing fuel design and performance, as well as advancing thermal-hydraulic methodologies including bundle critical power and pressure drop calculations. Proficiency in programming and coding is essential to support complex engineering and data analyses. Additionally, as part of the fuel development process, the role requires a strong understanding of single-phase and two-phase experimental programs, including the preparation of test matrices and supervision of component testing.
This role is part of the Thermal & Fluids Analysis team, which is responsible for thermal-hydraulic system codes and analyses in support of fuel development. The team oversees the development, maintenance, and technical consultation of thermal-hydraulic engineering computer codes, correlations, and methodologies pertinent to light water and advanced/fast reactors. The team plays a crucial role in ensuring the accuracy and reliability of analytical tools and methods that underpin reactor performance and safety evaluations.
