[cid:image004.jpg@01D685C0.EB336F80] The BNC Faculty Seminar Series is designed to provide faculty a platform to present an overview of their research and the opportunity for collaborative discussion with other BNC faculty and researchers across six colleges and 15 academic units. Yi Xie Assistant Professor in the School of Nuclear Engineering February 4th, 2021 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/91754078808 Title: Degradation of Structural Materials and Fuels in Nuclear Systems Abstract: One of the primary public concerns in the use of nuclear energy is to protect the public and environment from the potential release of radionuclides during normal and abnormal operations of the reactors and radioactive waste dry storage systems. The safety assessment of nuclear reactors and dry storage systems requires a mechanistic-level understanding about the thermodynamics, chemistry, and corrosion of radionuclides in the fuel, coolant, and structural materials. Each type of reactor designs must address unique material and engineering challenges, including high temperature operation, radioactive fluids, complex chemistry that can influence material degradation. The speaker will present the overview of the past and current research projects regarding degradation of structural materials and fuels in nuclear systems. The projects aim at understanding degradation mechanisms, relations between chemistry, microstructure and property, lifetime predictions of nuclear infrastructures, by conducting accelerated degradation studies under controlled and accelerate conditions, in-situ monitoring the component performance and degradation during long-term testing, and exploring alternative materials and structural enhancements. In the end of presentation, the speaker would like to discuss collaborations on projects that de-risk and speed the development of new nuclear technologies by high-throughput experiments and modeling. Bio: Prof. Yi Xie is an Assistant Professor in the School of Nuclear Engineering at Purdue University and joined Purdue in June, 2020. She worked as a Research Scientist at Idaho National Laboratory (INL), the division of advanced nuclear fuel development. She was the inaugural Glenn T. Seaborg Distinguished Postdoctoral Associate at INL, received the Ph.D. degree in Nuclear Engineering at The Ohio State University, and the B.E. degree at University of Science and Technology of China. She has more than 30 journal papers with most of them first-authored. Her research interests include corrosion in nuclear systems, advanced nuclear fuel, sensor materials and technology development, advanced sintering technology development, and geological repositories of radioactive waste. The research focuses on fundamental understanding and engineering applications of nuclear materials. Prof. Xie is interested at materials used on the nuclear reactor and fuel cycling system, exposed to extreme environments under irradiation and complex chemistry conditions. She designed and developed multiple complex test systems for nuclear materials study. She has extensive experience in advanced fuel fabrication, characterization, and development, based on her employment at INL and Purdue University.
