Research on Startup Condition of Steam Generator in China Experimental Fast Reactor

中国实验快堆蒸汽发生器为直流式,启动方式与压水堆核电厂的有较大区别,启动过程较为复杂。本文对中国实验快堆蒸汽发生器启动工况进行了研究,并将运行参数与理论设计参数进行了比较。结果表明,运行参数理论计算值与试验值基本吻合。提出了蒸汽发生器启动运行的优化方案,以指导运行人员操作,有效地保障了中国实验快堆功率运行试验的开展。

The steam generator in China Experimental Fast Reactor （CEFR） is direct flow type ,and the steam generator startup of CEFR is quite different and more compli‐cated than that of PWR .In this paper ,the startup condition of steam generator was studied ,and the operation parameters were compared with theoretical design parame‐ters .The results show that the calculated theoretical value of operation parameters is basically coincident with test value .The optimized startup program of steam generator for guiding operator was also introduced .The optimized procedure to start up the steam generator is proposed for guiding operators ,and it effectively ensures the power opera‐tion test of CEFR .
