| Abstract Scope |
Characterization methods capable of providing critical information across multiple structural length scales are essential in materials exposed to the extreme environments such as anticipated future fission and fusion power systems. Complementary techniques capable of uncovering the microstructural irradiation induced evolution are also important to verify and validate advanced computational models. In this presentation, we discuss our recent application of synchrotron-based x-ray scattering and absorption characterization methods in fusion and fission materials research. Specifically highlighted are opportunities in leveraging synchrotron-based techniques to address fundamental and applied materials science challenges at various length scales and in support of modeling efforts. Examples presented in this presentation include precipitate quantification in as-fabricated and as-irradiated fission-relevant steels and metallic alloys; microstructural quantification in neutron irradiated metal-hydrides for moderator applications; neutron irradiation induced structural degradation in ultra-high temperature ceramics; and quantification of the atomic structure of transmutation elements in tungsten-based plasma facing components. |
