摘要
对重水堆水平燃料通道内浮升力引发的间歇式流动(IBIF)现象进行模拟,对现象过程、燃料组件温度进行研究。由计算结果可以看出,燃料包壳温度随气泡的产生、生长以及排出的周期性变化,出现上升、下降的周期性变化;气泡在单元两侧开口处交替排出;气泡的排出带走燃料组件衰变热,使燃料包壳温度处于相对较低的水平。
In this paper,the phenomenon of Intermittent Buoyancy Induced Flow（IBIF） in the heavy water reactor（HWR） fuel channel is simulated.The IBIF phenomena and the fuel bundle temperature are analyzed.The calculation results indicate that the fuel bundle temperature rises and falls periodically accom-panying with the periodical initiation,grow and discharging of the bubble from the channel;the bubbles dis-charge from the two opening on the two sides alternately which removes the decay heat of the fuel bundles,and consequently the temperature of fuel bundle keeps low relatively.
