| 中文摘要 | 在快中子增殖反应堆的事故中,熔融物流经温度比较低的结构时会发生冻结,冻结的具体位置和时间对事故的发展影响较大。根据常用的导热冻结和整体冻结两种机理,采用机理建模方法,对熔融物的传播进行研究。模型采用积分微分法求解,并用法国GEY SER 8和GEY SER 11等实验进行了验证,得出整体冻结模型能更好地预测传播长度等结论。根据模型计算结果对当前存在悬疑的PV-A实验的逐步传播现象给出了合理解释。; In a severe accident in a liquid metal fast breeder reactor(LMFBR),molten material will flow into cooler structures and solidify,which will influence the continuing accident scenario.The conduction and bulk freezing mechanisms identified in previous investigations were used to develop an integro-differential predictive model for the freezing process.The GEYSER8 and GEYSER11 out-of-pile experiments conducted in France were used to validate the model.The results show that the bulk-freezing model more accurately predicts the penetration length.The computation results can also be used to explain the PV-A experiment's stepwise penetration phenomena. |
