    • 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.
    • 用于反应器的燃料元件包括具有纵向轴线的包层管和设置在其中的燃料。 至少一个通道形成在燃料和包壳管的至少一个中,并沿着包壳管的纵向轴线的方向延伸。 燃料元件还包括具有设置在其中的至少一个吸气材料的增压室。 在燃料元件中分离气体的方法可以包括在燃料元件中形成温差,使得至少一种气体能够进入形成在燃料元件中的至少一个通道中,并且将至少一种气体的一部分保持在至少一个气体中 吸气材料。 在燃料元件中分离气体的方法还可以包括使至少一种气体能够穿过形成在燃料元件中的多个通道的至少一个通道。
