| Abstract Scope |
Quantifying the porosity of graphite is critical to understanding its behavior in various advanced nuclear reactors. Properties such as pore size, pore connectivity, and tortuosity directly affect how reactor coolants can permeate into graphite during reactor operation. No single method can easily capture all of the characteristics that are critical to pore structure quantification. This presentation will discuss multiple methods that are being implemented to quantify the structures, including helium pycnometry nitrogen adsorption, FIB/SEM tomography, X-ray computed tomography, and other techniques. A discussion about the pros and cons of the techniques will be included, along with discussion about how to utilize these results for future modeling efforts. |
