Abstract: Disclosed is a method for manufacturing free-standing cladding tubes with multi-layer structures. According to the method, a cylindrical mandrel substrate defining a hollow cylindrical inner space is provided. A first cold spray powder metal is selected. The cylindrical mandrel substrate is rotated and the first cold spray powder metal is applied to an outer surface of the cylindrical mandrel substrate to form a first layer. The cylindrical mandrel substrate is removed.

Abstract: In a panel that uses the gamma radiation emitted by fission to produce electrical power, a source of an electrical current is connected to a layer of the panel made of a metal with a relatively high atomic number (Z) that forms an electron emitter. The emitter layer is surrounded by an insulation layer which in turn is surrounded by a relatively low Z value layer for collecting electrons from the emitter. Another layer of insulation and an outer sheath surround the collector. The improved panel may be used for reactor power level and power distribution measurements, and for initiating, maintaining or returning molten salt or metal coolants in the liquid state.

Abstract: 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.
