| 摘 要： | 为了确定某研究堆自然循环阀门直径,利用RETRAN-02分析模型,从自然循环阀(NCV)误打开和停堆后自然循环建立过程的角度,分析研究堆自然循环阀直径分别为150、200、250和300 mm时通过的流量、堆芯热通道的流量、燃料元件热点温度和最小偏离泡核沸腾比(MDNBR)的差异以及对反应堆安全的影响,最后选定NCV的直径为200 mm。

| Abstract: | Based on different natural circulation valve diameters of 150mm,200mm,250mm and 300mm.RETRAN-02 code is used to calculate the flow of the natural circulation valve(NCV) and the hot channel,the temperature of the hot spot,the minimum departure from nuclear boiling ratio(MDNBR),and to analyze the safety of thermo-hydraulic parameter from the two aspects of NCV abnormal open and the establishment of natural circulation.It is proved that the NCV diameter of 200 mm is suitable. |
