| Abstract Scope |
To predict the lifetime of any current or future component in a fission reactor with any degree of certainty requires a fundamental understanding of the materials response to coupled extreme environments. Many recent studies have highlighted that the response of material to two independent sequential harsh environments does not dictate the response to the same environmental exposure when they are simultaneous. We have developed an in-situ Scanning Electron Microscope (SEM) and a Transmission Electron Microscope (TEM) to elucidate the nuances of materials response to these coupled environments. In-situ TEM examples on quantitative room temperature irradiation creep, creep at 1200 °C, high temperature irradiation induced creep, and high cycle fatigue will be presented. Finally, recent efforts to explore coupled liquid, stress, temperature, and radiation environments in both TEM and SEM will be highlighted.
