| Abstract Scope |
Silicon Carbide (SiC) fiber reinforced SiC ceramic matrix composites (CMCs) are an accident tolerant fuel cladding for nuclear reactors due to their high temperature and irradiation stability. To realize the exciting benefits of this material, the impact on relevant in-core stress states on the gas tightness of a SiC CMC rod needs to be fully understood. General Atomics - Electromagnetic Systems (GA-EMS) is expanding an understanding of these complex failure modes through the development of in-situ methodologies that couple time dependent composite mechanical behavior with gas tightness performance, a critical metric for fuel rod applications. Tools like acoustic emissions, digital image correlation and X-ray tomography imaging are being integrated into the test design to pinpointing when, and under what loads, these CMC structures lose gas tightness. This improved understanding is being incorporated into advanced modeling tools being developed at GA-EMS to accelerate deployment of these exciting materials for extreme environments. |
