“Nanocrystal Formation and Evolution in Simulated High-Burnup Nuclear Fuels,” by Materials Scientist Yinbin Miao (CFC)
Nuclear fuels experience extreme temperature and radiation conditions in reactors and therefore form unconventional microstructures. In high-burnup UO2 fuel, nanocrystalline structure was found to form along with microscale pores. Knowledge about the formation mechanisms and evolution kinetics of this high-burnup structure (HBS) in UO2 is crucial for the reliable prediction of UO2 fuel performance, which may further impact the safety of nuclear reactors. In this study, a series of advanced material research and characterization capabilities were developed and utilized to simulate HBS formation and evolution under reactor conditions so that the corresponding mechanisms and kinetics can be unveiled.
Yinbin Miao joined Argonne in 2015 after he received his Ph.D. in nuclear engineering from University of Illinois Urbana-Champaign. He is a materials scientist in the Chemical & Fuel Cycle Technologies division. Miao has extensive experience in the microstructure investigation and fuel performance evaluation of various nuclear fuel materials using both experimental and modeling approaches.
“Exploring Nanoscale Materials as a Solid Lubricant at Elevated Temperatures,” by Materials Scientist Anirudha Sumant (NST)
Anirudha Sumant is a materials scientist at the Center for Nanoscale Materials (CNM) and currently leading the research on nanostructured carbon materials and superlubricity at the CNM.
