| 摘 要： | 简要地介绍了在ＬＢＢ分析中欠热或饱和液体在裂缝流道的一般排放特性，给出了考虑不平衡流动特性的求解泄漏率的基本方程组，并对商用３００ＭＷ核电站主管道热段作了泄漏率的实例计算，结果表明，在主管道中应用ＬＢＢ分析技术是可行的。

| Abstract: | This paper describes the general features of the discharge of initially subcooled or saturated liquid through crack of pipe for LBB analysis. The basic equations of leak rate in consideration of the features of nonequilibrium are given. Finally, the leak rate of hot leg of reactor coolant pipe in 300MW commercial NPP is calculated as a practial example. |
