| Abstract Scope |
Development of microstructure evolution models and their impact on physical properties are critical to predictive description of nuclear systems behavior. An important step in this effort is validation or parametrization of model parameters. In this presentation, I will discuss the importance of rate theory modeling to bridge the gap between atomistic and engineering scale models as well as validation of the multiscale models by tailored experiments. Specifically approaches to close the gap in space and time domains of the modeling and limited experimental results will be addressed by using a mapping function. A mapping function that recognizes limitation of sample geometry and resolution of electron microscopy will be applied to characterize extended defect evolution in irradiated materials utilizing electron microscopy and rate modeling. Finally, implications of spatially resolved post-irradiation characterization and accelerated irradiations on understanding nuclear fuel behavior will be discussed. |
