【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。
[Abstract]:Deviating from the design limit of bubble boiling ratio (DNBR) is the basis of reactor safety analysis. A reasonable calculation method is helpful to excavate more safety margin. In this paper, the RTDP and MSG methods commonly used in the design of nuclear power station are compared and analyzed. The principle and calculation flow of the method are introduced. Taking Lingao Phase I Nuclear Power Station in Guangdong Province as an example, the design limit of DNBR is calculated respectively. The results show that although the principles of the two methods are different, the design limits of DNBR are similar under the same operating conditions and statistical input parameters, and the design can be selected according to the specific application requirements.
