摘　　要：偏离泡核沸腾比(DNBR)设计限值是反应堆安全分析的基础,合理的计算方法有助于发掘更多的安全裕量。本文对比分析了核电站设计中常采用的RTDP和MSG方法,介绍了方法原理和计算流程,并以广东岭澳一期核电站为例,分别进行了DNBR设计限值计算。结果表明:虽然两种方法的原理不同,但在相同的工况和统计学输入参数条件下,DNBR设计限值相近,设计中可根据具体应用需求进行选择。The departure from nucleate boiling ratio （DNBR） design limit is the basis of nuclear reactor safety analysis. More safety margin could be clarified through the suit- able method. In this paper, the RTDP and MSG methods which were used in nuclear power plant （NPP） design were compared. The basic principle and calculation procedure were described. The DNBR design limits were respectively calculated for Ling＇ao NPP. The statistical principle of the two methods is different, but they obtain the similar result of DNBR design limit under the same condition and using the same statistical input parameter. For the safety design, the determination of method depends on the application.
