摘要: 采用ABAQUS6.7有限元分析软件,对高温气冷堆蒸汽发生器舱室混凝土在正常工况和设备冷却水系统停止供水事故工况下的温度场进行了计算。结果表明,在正常工况下,蒸汽发生器舱室混凝土的最高温度低于规定的限值;在设备冷却水系统停止对屏蔽冷却水系统供水事故工况下,7天内混凝土最高温度低于100℃,屏蔽冷却水系统能够保证对蒸汽发生器舱室的冷却。

Abstract: The finite element software ABAQUS 6.7 was used to calculate the field temperature of steam generator cavity concrete wall under normal condition and Component Cooling Water system shut-down con-dition.The calculation result shows that the maximum temperature is lower than that of the temperature limi-maximum temperature is lower than 100℃ after 7 days.The cooling system can provide enough cooling for the concrete wall.
