摘　　要：在破前漏(LBB)技术的应用中,需要计算通过裂纹的泄漏量。本文根据均相非平衡流理论建立了泄漏率的计算模型,并将计算结果与试验结果对比。结果显示,大部分计算得到的泄漏量与实验测量的泄漏量的偏差都在±50%以内,满足工程应用的要求,支撑了LBB的应用。Background： With the development of fracture mechanics, Leak-Before-Break （LBB） is widely used in nuclear power plant piping design. Purpose： In order to support the application of LBB, leak rate through crack need to be calculated. Methods： In this text, an analytical flow model is developed based on homogeneous non-equilibrium model, a computer program is also developed based on this analytical model. Results： Comparison between the results from the above program and test results shows that deviations of calc. results to test results are within ±50%. Conclusions： Conclusions can be got that this analytical model and computer program meet the requirement of engineering application.
