中国实验快堆失去厂外电后单台主泵停运的—回路瞬态特性分析

Study for CEFR Primary Circuit Transient Performance in Case of One Primary Pump Trip during Loss of Off-site Power

失去厂外电源是在中国实验快堆(CEFR)运行寿期内可能多次发生的预计运行事件。本文基于自主研发的系统瞬态分析程序FASYS分析了CEFR失去厂外电源后单台主泵停运的事件,并将事件过程中的关键参数与试验结果进行了对比。通过试验和模拟分析,得到了中国实验快堆失去厂外电源后单台主泵停运的一回路瞬态特性。

Loss of off-site power test is one of anticipated operational occurrences ot China Experimental Fast Reactor. In the paper, the transient was simulated and analysed by FASYS code, which was developed by ourselves, and comparisqn between the test and theoretic results was carried out. The paper illustrated the transient performance of CEFR primary circuit in case of primary pump trip during loss of off-site power.
