YIN Haifeng LIANG Bingbing XU Ning. Development of leak rate calculation model and code in piping[J]. Nuclear techniques, 2013, 36(4): 040618 DOI: 10.11889/j.0253-3219.2013.hjs.36.040618.
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.
