Biography

Dr. Meric de Bellefon is a Nuclear Materials Engineer in charge of irradiation testing, tribology testing, fuel characterization and quality control at Kairos Power. Previously he was an Assistant Scientist working in the Materials Science and Engineering Department in collaboration with the Grainger Institute for Engineering and Dr. Dan Thoma. He is interested in the use of metal additive manufacturing to fabricate functionally-graded materials for energy applications, and in the development of in situ monitoring techniques to better control microstructure development during metal additive manufacturing. Dr. Meric de Bellefon obtained a PhD in Nuclear Engineering from the University of Wisconsin – Madison in 2018, during which he focused on the development of nano-structured stainless steels for nuclear power applications. He was awarded the Department of Energy NEUP Graduate Fellowship in 2015. Dr. Meric de Bellefon graduated with an M.S. in Nuclear Engineering from University of California – Berkeley in 2009, and a B.S. in Physics from Ecole Polytechnique, France in 2008.

A key strategy to increase the radiation resistance of materials has been to introduce a high density of interfaces that can act as sinks for radiation-induced defects. Twin boundaries are a type of interface that can be introduced through deformation but are usually considered to be ineffective sinks. Using heavy ion irradiation and transmission electron microscopy, this study investigates the influence of a high area per unit volume of twin boundaries on the radiation-induced swelling response of an austenitic stainless steel. The study shows that swelling can be suppressed in regions containing a high density of closely-spaced deformation twin boundaries.
