摘要
本文利用MELCOR1.8.5程序建立了典型的M310核电站的严重事故模型,基于该模型设计了多种非能动的缓解措施,针对由全厂断电诱发的严重事故,模拟研究了这些非能动安全措施的缓解效果。研究结果表明:在全厂断电事故下,堆芯补水箱系统、堆腔注水系统、非能动余热排出系统均能有效地投入使用,并显著地延缓事故的发展,将核电站稳定在一个安全的状态,为人工干预赢得更多时间。
A severe accident model of typical M310 nuclear power station with MELCOR 1.8.5code was constructed in this paper.Based on the model,several passive safety measures were designed,and their benefits of mitigating the accident caused by station blackout（SBO）were simulated.The calculating results show that the core makeup tank system,external reactor vessel cooling system and passive residual heat removal system can operate successfully in SBO,postpone the progression of the accident markedly,stabilize the M310 nuclear power station in a safe state and gain more time for manual intervention.
