The Nuclear Science and Engineering (NSE) Division is seeking a Nuclear Engineering Postdoc to provide support in the analysis of multi-physics aspects of nuclear fission reactors including fuel behavior, materials, neutronics, thermal-hydraulics, and structural mechanics. The candidate will assist in investigation of the performance of nuclear fission reactors and fuel cycle facilities and contribute to optimization of reactor and fuel cycle design. In this position, the candidate will develop computational methods and/or computer codes to model the physics and engineering of reactor and fuel cycle systems. The particular focus of this position includes the integration of the physical modeling of advanced reactor fuels and materials, treatment of multiphase/multicomponent fluid dynamics, and implementation of highly optimized and stable numerical and computational methods. This role requires the production of papers and reports describing results of development work, analyses, and investigations and the ability to integrate within a multi-faceted software development team. **Position Requirements** + Knowledge of one or more specialized areas of fission reactor physics, engineering, or fuel systems. + Knowledge of nuclear engineering principles, theories, and practices for the design and analysis of reactor systems. + Skill in the conception, design, and evaluation of innovative approaches and solutions to quantitative problems is necessary. + Knowledge in fuel and materials modeling as they relate to advanced reactors is preferred. + Knowledge in multiphase and/or multicomponent fluid dynamics as related to advanced reactor fuels/materials and the application of these methods is preferred. + Knowledge in numerical and computational methods and the application of these methods of advanced physical models is preferred. + Skills in the use of computers and in the analysis of computational results, in the clear and effective documentation and communication of results, and in interaction with co-workers and support personnel is required. + Knowledge of modern software development practices and object-oriented programming techniques is required. + Ability to model Argonne’s Core Values: Impact, Safety, Respect, Integrity, and Teamwork. Other: the required levels of knowledge and skills are typically achieved through formal training in engineering or physics on the Ph.D. (or equivalent) level. **Job Family** Postdoctoral Family **Job Profile** Postdoctoral Appointee **Worker Type** Long-Term (Fixed Term) **Time Type** Full time _As an equal employment opportunity and affirmative action employer, and in accordance with our core values of impact, safety, respect, integrity and teamwork, Argonne National Laboratory is committed to a diverse and inclusive workplace that fosters collaborative scientific discovery and innovation.
