The invention relates to a multilayer cladding including a combination of ceramic and metallic components. The multilayer coating includes an inner layer, an intermediate layer and an outer layer. The inner layer can form the cladding structure, the intermediate layer can include a ceramic composite or ceramic-containing composite composed of interlocking woven or braided fibers, e.g., fiber tows wrapped on the inner layer to form a woven structure, and a matrix material, and the outer can be composed of metal or metal alloy, such as, in the form of a coating. The multilayer cladding is effective to protect contents of the cladding structure from exposure to high temperature environments.

The invention relates to remotely operated laser sintering systems and methods for manufacturing pellets containing highly radioactive elements. The highly radioactive elements can be recovered from used nuclear fuels. The systems and methods of the invention employ a feed composition including one or more highly radioactive elements and a ceramic matrix material. The feed composition is distributed in the form of a layer and sintered by directing at least one laser beam to form a pattern in the layer of the feed composition. The pattern corresponds to the shape of the pellet. Further, the sintering process can be repeated as necessary to achieve a pre-determined pellet height.
