摘要: 利用RELAP5/MOD3.4程序对CPR1000非能动余热排出系统在全厂断电事故(SBO)下的流动特性进行分析,主要分析了非能动余热排出系统空气冷却器的布置方式和空气冷却塔的高度对蒸汽发生器(SG)二次侧流动不稳定性的影响。计算结果表明,水平布置的空气冷却器可以明显减小SG二次侧流动不稳定性;随着空气冷却塔高度增加,SG二次侧流动不稳定性减小;CPR1000在发生SBO后,非能动余热排出系统完全可以导出堆芯余热,保证反应堆处于安全状态。

Abstract: The CPR1000 Passive Residual Heat Removal（PRHR） System were investigated using RE-LAP5/MOD3.4 under the condition of Station Blackout（SBO）.The flow instability of SG secondary side was affected by the arrangement of the air-cooled heat exchanger and the height of the cooling tower.The calculation results showed that the horizontal layout of the air-cooled heat exchanger could reduce the flow instability obviously,and the instability decreased with the increase of the cooling tower.The results also showed that the PRHR of CPR1000 could remove the core residual heat after the SBO to ensure the safety of the reactor.
