摘　　要：本文应用WGOTHIC程序对AP1000核岛整体分工况建模,系统分析了多种情况下冷却水装量对安全性的影响。结果表明:非能动安全壳冷却系统失效1 000s后,安全壳超压;冷却水冷却72h后得不到冷却水的补充,0.9d后安全壳超压;冷却水冷却19.6d后,安全壳虽超压,但小于安全壳屈服极限压力;冷却水冷却30d后,空气冷却已足够带走堆芯衰变热,而不需人为干预。结果为应急计划制定和设计改进提供了依据。The WGOTHIC code was used to analyze the influence of the containment cooling water inventory to containment safety for different cases. The results show that if passive containment cooling system fails, the pressure in containment is beyond design limit after 1 000 s; if cooling water can＇t be supplied after 72 h, the pressure in contain- ment is beyond design limit after 0.9 d if cooling water can＇t be supplied after 19.6 d, the pressure in containment is beyond design limit but less than the breakdown pressure if cooling water is supplied for 30 d, the air cooling can remove the decay heat without any aid. It is a reference for making emergency plan and improving containment design.
