A multi-layered ceramic tube (Figure 1) to contain fissile fuel within a nuclear power reactor, particularly as cladding layer for a fuel rod in a nuclear power plant or reactor, having an inner layer (20) of high purity beta phase stoichiometric silicon carbide, a central composite layer (22) of continuous beta phase stoichiometric silicon carbide fibers, and an outer layer (24) of fine-grained silicon carbide, to improve initial crack resistance, stiffness, ultimate strength, impact resistance and thermal shock resistance. |
