摘要
介绍了中国改进型压水堆1000MW核电站(CPR1000)设计瞬态计算中的RETRAN程序建模方法。首先对核岛主设备几何参数进行计算;然后按照应力计算的要求,对CPR1000主设备进行了详细地模拟,建立了大量的控制容积和导热构件。分别进行了稳态调试以及事故瞬态计算,并与珐玛通公司的计算结果进行了比较。结果表明,RETRAN程序模型基本满足设计瞬态分析和设备应力分析边界条件的模拟要求。
This paper discusses the method about RETRAN modeling for designed transient calculation of CPR1000. Firstly, the geometric parameters of the main equipments in the nuclear island are calculated. Secondly, according to the needs of stress calculation, we simulate the main equipments in a detailed way during which a large amount of volume and heat structures are modeled. As a result, the model basically meets the requirement of transient analysis and addition in stress analysis.
