Safety injection actuation test was performed at Full-scale Simulator of QinshanⅡNPP, the initial condition for the test was same as one for the SI actuation test of Unit 1 during commissioning. SI signal was triggered by low-low steam pressure through opening the steam dump valves to atmosphere. Comparing the results obtained from the simulator and real data from the commissioning of Unit 1 showed that the results from the simulator were more conservative from view points of safety, so the models and parameters for the simulator were credible.

在秦山第二核电厂全范围模拟机上进行1号机组调试期间安注试验工况下的安注试验(打开主蒸汽大气排放阀产生主蒸汽压力低低信号触发安注信号)，得到的结果与调试得到的实际数据进行比较，发现从安全方面考虑，模拟机得到的结果更为保守，说明模拟机计算模型和参数设定是可信的。
