| Abstract Scope |
Graphite and carbon-based materials are key structural materials for current and future nuclear reactors. The microstructure of these materials is complex, even though they are a single element material, and difficult to quantify because the microstructure features range in sizes over multiple length scales. The evolution of the bulk property changes is currently being studied through multiple irradiation programs at multiple research facilities, but these programs primary driver is engineering data without the fundamental understanding of the microstructural changes that cause the bulk property evolution. Work at Oak Ridge National Laboratory (ORNL) is leveraging samples from several of these irradiation campaigns to begin understanding how the microstructure changes. This presentation will discuss the general bulk property evolution that occurs in graphite and present the current work being performed at ORNL to study the link between the microstructure evolution and the bulk properties. |
