Joining and Hermetic Sealing of Silicon Carbide for LWR Applications

More about the book

The book delves into the promising use of Silicon Carbide (SiC) as a cladding for accident-tolerant fuels, highlighting its advantageous properties. It addresses the critical challenges of joining and hermetic sealing, essential for maintaining SiC's effectiveness as a barrier against fission products. The research explores the application of metals like Al, Cr, and Fe, along with a specialized FeCrAl alloy, to achieve effective bonding. Experiments focused on coating SiC with thin films similar to FeCrAl, leading to successful high-temperature diffusion bonding and satisfactory material integration.
