A tubular ceramic component suitable for being used in a nuclear reactor

A tubular ceramic component is provided for being used in a nuclear reactor. The component comprises an inner layer of silicon carbide, an intermediate layer of silicon carbide fibres in a fill material of silicon carbide, and an outer layer of silicon carbide. The intermediate layer adjoins the inner layer. The outer layer adjoins the intermediate layer. The silicon carbide of the inner layer, the fill material and the outer layer is doped and comprises at least one dopant in solid solution within crystals of the silicon carbide.
