| Abstract Scope |
GA-EMS is using the Accelerated Fuel Qualification framework (AFQ) for silicon carbide (SiC) composite (SiC-SiC) reactor materials. AFQ is an initiative to formalize requirements and methodology for reducing the timeframe needed to qualify new nuclear materials. As a fiber reinforced ceramic composite, the modeling of this material is challenging, and three different modeling efforts are being pursued to simultaneously improve the predictive capability of current modeling approaches. These efforts include a constitutive-surrogate approach, an ANSYS based fiber tow model, and improvements in the BISON SiC framework. Efforts to incorporate the complicated mechanical response of SiC-SiC will be discussed, showing that matching the experimental stress strain curve within the model is a good first step, but does not fully capture the advanced failure modes of these materials. In addition, where this modeling belongs within the AFQ framework and future work to incorporate these models into a digital twin will be presented. |
