    摘要： Fuel elements for use in reactors include a cladding tube having a longitudinal axis and fuel disposed therein. At least one channel is formed in at least one of the fuel and the cladding tube and extends in a direction along the longitudinal axis of the cladding tube. The fuel element further includes a plenum having at least one getter material disposed therein. Methods of segregating gases in fuel elements may include forming a temperature differential in the fuel element, enabling at least one gas to travel into at least one channel formed in the fuel element, and retaining a portion of the at least one gas with at least one getter material. Methods of segregating gases in fuel elements also may include enabling at least one gas to travel through at least one channel of a plurality of channels formed in the fuel element.

    摘要： Methods of forming composite bodies and materials including a metal oxide, such as, uranium dioxide, and silicon carbide are disclosed. The composite materials may be formed from a metal oxide powder, a silicon carbide powder and, optionally, a carbon powder. For example, the metal oxide powder, the silicon carbide powder and the carbon powder, if present, may each be combined with a binder and may be deposited in succession to form a precursor structure. Segments of the precursor structure may be removed and pressed together to form a multi-matrix material that includes interlaced regions of material including at least one of the metal oxide powder, the silicon carbide powder and, optionally, the carbon powder. The segments may be extruded or coextruded with another material, such as, a silicon carbide material, to form a green body. The green body may be sintered to form the composite bodies and materials having a desired final density.
