摘要:
本发明涉及一种环形核燃料棒。该环形燃料棒包括外管;具有小于外管的直径并与外管同轴地布置的内管;邻近于内管,在外管和内管之间装载的多个内环形芯块;邻近于外管,在外管和内管之间装载的多个外环形芯块。优选,该内环形芯块与外环形芯块隔开,具有中间隙。该环形核燃料棒可以除去内管和外管之间不平衡的热通量,以及控制内管和外管之间的热通量。
摘要(英):
The invention relates to an annular nuclear fuel rod. The annular fuel rod includes an outer tube; an inner tube having a diameter smaller than that of the outer tube, and arranged coaxially with the outer tube; a plurality of inner annular pellets loaded between the outer and inner tubes, adjacent to the inner tube; a plurality of outer annular pellets loaded between the outer and inner tubes, adjacent to the outer tube. Preferably, the inner annular pellets are spaced from the outer annular pellets with an intermediate gap. The annular nuclear fuel rod can remove unbalanced heat flux between inner and outer tubes, and furthermore, control the heat flux between the inner and outer tubes.
