| 摘 要： | 以瑞典Ringhals压水堆核电站为参考对象,采用最佳估算程序SCDAP/RELAP5/MOD3.2,建立典型的3环路压水堆严重事故计算模型,分析全厂断电(SBO)事故造成的堆芯熔化进程,研究高压安全注射系统对该事故的缓解能力。计算结果表明,堆芯出口温度达到920 K时的严重事故管理策略,即卸压充水缓解措施可以有效地阻止堆芯熔化,能使堆芯长期处于稳定状态。

| Abstract: | Choosing Sweden Ringhals PWR as reference plant and using the best estimate computer code SCDAP/RELAP5/MOD3.2,a representative three loops PWR severe accident calculation model is established and Station blackout(SBO) induced core melt progression is analyzed.The mitigating capability of high-pressure safety injection system to severe accident is studied.The calculation results show that the severe accident management strategy of bleed-and-feed cooling when the core outlet temperature reaches to 923K can prevent core damage effectively and the reactor core can achieve a long term safe stable state. |
