Abstract
Structural materials such as stainless steel and nickel-based alloys deployed in nuclear reactors are exposed to extreme environments comprising temperature, irradiation, stresses, and corrosive – corrosion, radiolysis and hydriding media, which poses significant challenges that demand immediate attention for the life extension of current light water reactors (LWRs) and the successful realization of next generation of nuclear reactors. This talk will discuss the use of in situ coherent X-ray diffraction imaging techniques to investigate corrosion and radiolytic processes in model nickel alloy. We will examine how corrosion-induced lattice defects evolve over time in both pristine and irradiated Ni under simulated LWR conditions.
Biography
Ericmoore Jossou is an assistant professor in the Nuclear Science and engineering and Electrical Engineering and Computer Science Departments at MIT. Before moving to MIT, he worked at Brookhaven National Laboratory. He received his PhD in Mechanical Engineering with concentration in Materials Science in 2019 from the University of Saskatchewan. He has a BSc in Chemistry from the Ahmadu Bello University, and MSc in Materials Science and Engineering from the African University of Science and Technology in 2013. His research interest is in materials design for nuclear energy applications. He currently leads the materials in extreme environment research group, which combines experiments with computational methods to establish structure-properties-performance relationships in materials for nuclear energy applications.
