Abstract Scope |
Structural materials, breeding blankets and plasma facing components (PFCs) require performance improvements in moving from ITER to future fusion pilot plants. Materials performance is determined by extreme thermal and radiation environment that induces microstructural evolution and property changes, determined by a large span of spatial and temporal scales. Fortunately, recent innovations in computational modeling techniques, increasingly powerful high-performance computing platforms, and improved analytical experimental characterization tools provide the means to develop self-consistent, experimentally validated models of structural materials and PFC performance in the fusion energy environment. This presentation will describe the challenges and opportunities associated with modeling the performance of structural and blanket materials, and divertor PFCs in a next-step fusion materials environment, and provide examples of recent progress to investigate the dramatic surface evolution of tungsten exposed to low-energy He and H plasmas, as well as the coupled He-defect evolutions in bulk structural materials exposed to fusion environments. |
