Most of the reactor core components for the Transformational Challenge Reactor (TCR) will be built through additive manufacturing (AM). The performance of the SiC fuel matrix is particularly important because it must demonstrate sound structural stability and acceptable heat transfer properties, as it serves as the fuel particle matrix, an additional barrier to fission product release, and a heat transfer medium. A recently developed binderjet printing process combined with chemical vapor infiltration (CVI) is being leveraged to produce the SiC fuel matrix for the TCR core. However, detailed microstructural evaluation of this 3D printed SiC and its stability under irradiation conditions is required for reactor design and material qualification purposes. High-resolution electron microscopy is being used to evaluate the microstructural evolution of 3D printed SiC after ion irradiation and neutron irradiation. Detailed comparisons will be made with reference chemical vapor deposition (CVD) SiC.
