Radiation Effects and Microstructural Analysis


Advance the understanding of radiation effects in materials science and provide scientific breakthroughs in materials technology for future nuclear devices.


Explore the intricate interplay between radiation and materials, aiming to unravel fundamental damage and recovery mechanisms in metals and ceramics under irradiation. Advance scientific knowledge to enable the design of radiation-resistant materials for future fission and fusion energy systems. 

R&D Scope

The Radiation Effects and Microstructural Analysis Group primarily focuses on understanding radiation effects in nuclear materials. Its research activities encompass the development of radiation-resistant materials, comprehensive characterization before and after irradiation, and the establishment of advanced irradiation and post-irradiation experiment technologies. The group's research process involves experimental and theoretical analyses of radiation-induced nano to macroscale processes in irradiated materials, providing scientific feedback for the designs of radiation-resistant materials and advanced nuclear components. The group conducts numerous national and international programs focused on studying radiation effects in materials, facilitated by strong collaborations with other research groups and nuclear facilities at ORNL.
