Zusammenfassung:	PURPOSE: A fuel rod including an internal hydrogen/tritium getter structure and an assembly of fuel rods are provided to realize a getter or suction structure for effectively maintaining and absorbing the hydrogen and tritium. CONSTITUTION: A fuel rod(48) including an internal hydrogen/tritium getter structure comprises an upper part(73) and a lower part(74). The fuel rod includes a plurality of nuclear fuel pellets(62), an upper-end plug(56), a lower-end plug(58), at least one halo gas inhalation structure(80) and a gas inhalation structure. The nuclear fuel pellets are the cladding material and comprises an upper fuel pellet(70) and a lower fuel pellet(72). The plugs are enclosed by the fuel rod and nuclear fuel pellets. A separating unit is arranged between the upper-end plug and upper fuel pellet. The halo gas inhalation structure is arranged within the fuel rod.
