Biography

Fei Teng is a Staff Scientist at the Idaho National Laboratory (INL), specializing in materials science. After earning his Ph.D. in Materials Science from Oregon State University in 2018, he joined INL in 2019 as a research scientist and was promoted to staff scientist in 2022. Teng's work at INL focuses on nuclear fuels and structural materials, where he has conducted extensive research on the mechanical stability of TRISO particle fuel. He utilizes micro-mechanical testing and neutron irradiation techniques to study the impact of microstructural changes on mechanical integrity. His research also investigates the thermal irradiation degradation of Ni-based alloys and their corrosion behavior in molten salt environments. Teng's contributions have been recognized with several accolades, including the U.S. Department of Energy Secretary of Energy Achievement Awards in 2024 and being selected as the INL MFC Mentor of the Year in 2023.
