The role will ensure the development of the systems and components through production including any necessary prototyping, testing, and commissioning. Job Profile Tasks/Responsibilities: Develop and implement methodologies to qualify and characterize materials, especially metallic alloys, graphite, composites, and welding materials for nuclear reactor applications including in high temperature environments. Support selection of appropriate materials, test methods, codes and standards, and prepare material specifications for component procurement. Inform development of and assist in oversight of materials testing programs to collect material properties and establish basis for material qualifications. Use engineering tools, including appropriate simulation software, hand calculations, and engineering judgment, assess microscale behavior, grain boundaries, surface effects, degradation behavior (corrosion, oxidation kinetics, neutron damage, etc.), and lifetime performance of materials. Perform and assist metallurgical analysis for the alloys selected for metallic systems, structures, and components of X-energy developed reactors, including pressure vessels and piping, reactor internals, heat exchangers, and other systems and components. Collect and use data to support the generation of constitutive material models and perform and assist structural integrity, creep-fatigue, and strain evaluations for metals at high temperatures. Support the assessment of SSCs for response to environmental conditions at the direction of project leads. Consider effects of tribology and material property evolution on system and component design as a function of temperature and environment. Write and develop design and analysis documentation including design basis documents, technical reports, calculations, and drawings in accordance with applicable procedures, as well as industry publications and engagement in professional forums. Develop Verification and Validation (V&V) plans for analytical tools and support qualification of toolsets.
