  • Publication number: 20230368931
    Abstract: In various aspects, a nuclear fuel rod cladding is disclosed. The cladding can include a base tube and a mesh structure including gaps therein. The base tube can include an elongated tubular wall and can be configured to house nuclear fuel therein. The mesh structure can be positioned along at least a portion of the elongated tubular wall and can be configured to provide structural support to the base tube. In one aspect, the gaps of the mesh structure are designed to permit neutrons emitted by the nuclear fuel to pass therethrough to escape the fuel rod cladding.

  • Publication number: 20230220556
    Abstract: Plated metallic substrates and methods of manufacture are provided. The method comprises depositing a first layer onto at least a portion of the metallic substrate to create a coated substrate utilizing physical vapor deposition. The method comprises electroplating a second layer comprising chromium, a chromium alloy, or a combination thereof onto at least a portion of the first layer to create a plated substrate.

  • Patent number: 11598008
    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.

  • Publication number: 20220375631
    Abstract: A nuclear fuel cladding tube is described herein that includes a zirconium alloy tube having an outer wear and oxidation resistant ceramic coating selected from the group consisting of CrN, Cr2N, CrWN, CrZrN, and combinations thereof. The cladding may have an intermediate layer formed between the tube and the outer ceramic coating. The intermediate layer may be selected from the group consisting of Ta, W, Mo, Nb, and combinations thereof. Both the intermediate layer and the outer ceramic coating may be deposited by physical vapor deposition.
