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.
