Abstract Scope |
SiC-SiC composites are a prospective material of fuel cladding for Light Water Reactors (LWRs). This material is manufactured to withstand steam oxidation, with high strength and low neutron cross section. In this research X-ray Computed Tomography (XCT) scans of as received and neutron irradiated samples are analyzed with image segmentation. SiC-SiC composite samples with different microstructures exposed at low and high thermal flux conditions were studied to determine the performance of this type of cladding. The analysis of this data shows some of the possible microstructural changes, crack propagation and defects that may be produced by irradiation and temperature gradients. Moreover, the results obtained in this research can also be linked with thermal and mechanical properties induced by irradiation. Studies on monolithic SiC-SiC composites have been performed before, however, no work has been conducted in multi-layered SiC-SiC composites tubes, making this work unique. |
