Abstract Scope |
Much excitement arose in nuclear energy research communities around the globe with the discovery of nanostructured ferritic alloys (NFA) at the beginning of the 21st century. NFA’s evolved from oxide dispersion strengthened (ODS) alloys, which have been around for many decades, due to refinement in the microstructure consisting of an ultra-fine grain structure and high concentration of nano-size (~2-5 nm) oxide particles. Many studies have demonstrated that NFA’s possess remarkable high-temperature strength resulting in outstanding creep performance combined with very low swelling rates and less hardening during exposure to high-dose irradiations. This presentation will cover progress made in the Nuclear Technology Research and Development Program’s Advanced Fuels Campaign that emphasizes understanding fabrication methods for producing thin wall tubing, including studies dealing with recrystallization, texture and plastic deformation and the response of microstructure and mechanical properties of NFA exposed to neutron irradiation. |
