中国实验快堆1台一回路泵切除试验计算模拟与分析

Simulation and Analysis of One Main Pump Trip Test on CEFR

为检验中国实验快堆(CEFR)发生1台一回路泵切除事件时的安全性,拟在CEFR上进行试验验证。为确保试验的安全性,利用系统分析程序OASIS对试验过程进行了模拟,并对试验可能存在的风险进行了分析。计算结果表明:按照试验步骤进行操作不会对反应堆安全构成威胁;试验初期存在一些风险,源于主热传输系统各回路的流量不匹配问题,可能会对设备产生较大的热冲击。

To verify the safety of China Experimental Fast Reactor （CEFR） under one main pump trip state, a test is going to be performed on CEFR. In order to ensure the safety of reactor, the system code OASIS was applied to simulate the test and analyze the risk existed. The calculation results show that the operation in accordance with the test procedure will not pose a threat to the safety of reactor and the most possible risk derives from the flow rate mismatch problem between main heat transfer systems, which may cause a significant thermal shock to components.
