General Atomics–Electromagnetics (GA-EMS) is developing SiGAŽ composite technology, an engineered SiC fiber reinforced, SiC matrix (SiC-SiC) composite, for light water reactor applications to deliver improved normal operational performance and enhanced safety. Progress will be reported on the scaling of SiGAŽ cladding fabrication for lead test rods (LTRs) by 2025, including increases in cladding length capacity and throughput through different fabrication steps. Design work on advanced SiGAŽ fuel rods to support high burn-up, high enrichment fuel with SiC-SiC-based cladding show encouraging results, improved thermo-mechanical properties, meeting of dimensional specifications at longer lengths, and promising hydro thermal corrosion performance. These advances are preparing SiGAŽ cladding for upcoming irradiations at Southern Companies Vogtle plant and Idaho National Lab’s Advanced Test Reactor. In addition to cladding development, SiGAŽ structures are being brought to bear on other in core structures, further advancing the concept of accident tolerant fuel towards a fully accident tolerant core.
