Abstract Scope |
As X-ray tomography is non-destructive it provides a unique opportunity to non-destructively examine the same region of a nuclear fuel or structural material pre- and post-irradiation. Such information can potentially be obtained at sub-micrometer resolution. One of the major challenges limiting the use of X-ray tomography in nuclear research is the significant mass attenuation of Uranium. Often, a traditional lab-based micro-focus or nano-focus source is incapable of practically imaging more than a millimeter of a fuel such as UO2. Additionally, imaging fuel and surrounding material (such as cladding) becomes difficult due to the significant differences in x-ray mass attenuation and limited dynamic range of traditional detectors.
This work will utilize a TRISO fuel form to demonstrate a means to image “around” fuel and provide a high quality, high resolution reconstruction of the TRISO fuel kernel as well as the surrounding low-density low mass attenuation (pyrolytic carbon and silicon carbide) layers. |
