Mechanical properties of SiC/SiC braided tubes for fuel cladding
Journal of Nuclear Materials, 2014Abstract Axial and hoop tensile tests are performed at room temperature on SiC fiber CVI matrix tubular samples. A layer-to-layer interlock 3D braided preform is used. An elastic damageable mechanical behavior resulting from the development of matrix and delamination cracks is evidenced.

Fabrication of SiC–SiC composites for fuel cladding in advanced reactor designs
Progress in Nuclear Energy, 2012Abstract Both advanced fission reactor concepts and fusion energy systems demand materials that can survive extremely harsh operating environments having persistent high temperature and high neutron flux conditions. Silicon carbide fiber/silicon carbide matrix (SiC–SiC) composites have shown promise for these applications, which include fuel cladding

Finite element analysis of the SiC/SiC composite clad deformation in the presence of spacer grids
Annals of Nuclear Energy, 2020Abstract The deformation of a two-layer SiC clad in the context of pressurized water reactor fuel assembly has been analyzed in the present work. Firstly, azimuthal temperature difference that can lead to clad bowing has been estimated using a plane strain model in BISON.

Stress Analysis of Three-Layer SiC Cladding for PWRs
Volume 3: Nuclear Fuel and Material, Reactor Physics and Transport Theory; Innovative Nuclear Power Plant Design and New Technology Application, 2017Silicon carbide (SiC) and SiC matrix composites (SiCf/SiC) are being investigated as potential fuel cladding materials for advanced PWRs in order to improve the safety of nuclear power plants. The conceptual design of multi-layered SiC cladding (consisting of a monolithic SiC layer, SiCf/SiC composite layer and a monolithic SiC coating layer) has been ...

Mechanical performance of SiC three-layer cladding in PWRs
Nuclear Engineering and Design, 2016Abstract The silicon carbide cladding concept is currently under investigation with regard to increasing the accident tolerance and economic performance of light-water reactor fuels. In this work, the stress fields in the multi-layered silicon carbide cladding for LWR fuels are calculated using the commercial finite element analysis software ADINA ...

High-power air-cooled SiC-clad Nd:YVO_4 slab lasers
Optics Letters, 2011We demonstrate a diode-pumped, air-cooled, 100 W class SiC-clad Nd:YVO(4) active slab laser based on diffusion bonding of two SiC plates to a thin Nd:YVO(4) slab. We obtained 83 W of cw output power with a slope efficiency of 27% without water cooling.

Laser cladding of Al-Si/SiC composite coatings: Microstructure and abrasive wear behavior
ICALEO 2007: 26th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2007Surface coatings of an Al-Si-SiC composite were produced on UNS A03560 cast Al-alloy substrates by laser cladding using a mixture of powders of Al-12 wt.% Si alloy and SiC. The microstructure of the coatings depends considerably on the processing parameters.
