Yiren Chen

Dr. Yiren Chen is a principal metallurgical engineer in the Nuclear Science and Engineering division at Argonne National Laboratory. His research focuses on the degradation of structural materials in light water reactors and sodium-cooled fast reactors due to irradiation damage and corrosive environments. He has extensive experience in conducting mechanical tests on radioactive materials under simulated reactor conditions. He has led numerous research projects on irradiation-assisted stress corrosion cracking, radiation damage and effects, interactions of sodium with materials, as well as welding and additive manufacturing technologies. In addition, he provides technical support to the U.S. Nuclear Regulatory Commission on material aging and degradation issues concerning nuclear power plants. Dr. Chen is also actively involved in various nuclear materials research initiatives at Argonne, aiming to advance the understanding of degradation mechanisms in structural materials for nuclear power systems.
