摘要 分析了国内外压水堆核电厂燃料包壳破损诊断方法以及存在的问题,从燃料棒破损数量、破损尺寸和燃耗3个方面对压水堆核电厂燃料包壳破损的诊断方法进行了改进,并对可能影响诊断结果的因素进行了探讨。应用我国在役核电厂实际的运行数据对诊断方法进行了验证,结果表明,改进后的燃料包壳破损诊断方法可准确地诊断燃料包壳破损情况,且有更广泛的适用性。 The diagnosis methods in the world for the fuel failures in PWR and the existing problems of diagnosis methods are analyzed and improved from three aspects,which are the number of failed fuel rods,fuel failure size and burnup of failed fuel.The factors that may affect the diagnosis result are also identified and discussed.The operating data of Chinese in-service nuclear power plants are used to verify the improved diagnosis method,and the results show that,the improved diagnosis method for fuel failures can accurately diagnose the fuel failure and has a wider applicability.
