This paper presents recent achievements in joining methods developed for the closure of tubular CVI-SiCf/SiC composites considered as cladding solution for Light Water Reactor (LWR) fuel rods. This study was conducted as part of a collaboration between Framatome and CEA (Commissariat à l’Energie Atomique et aux Energies Alternatives). Based on CEA non-reactive BraSiC$^R$ process, various brazing systems were investigated. X-ray tomography of the BraSiC$^R$ joints showed satisfactory filling by the braze. Mechanical “push out” tests and destructive characterizations (cross sections for optical and SEM observations) were conducted before and after hydrothermal corrosion testing in an autoclave at 360°C and 187 bars in LWR water conditions. The results depend on the composition of the BraSiC brazes and demonstrate the relevance of BraSiC process for SiC-based E-ATF fuel rods for LWR.
