Review of Experimental Research of Flow-Iinduced Vibration of Reactor Internals
-
摘要: 简要描述了近年来完成的多个反应堆的堆内构件流致振动试验研究工作,以及按照美国核管会导则R.G.1.20的要求对结构进行的流致振动综合评价。内容包括秦山核电厂二期反应堆堆内构件流致振动综合评价、ACP1000堆内构件模型流致振动试验研究、华龙一号的流致振动评价计划,也介绍了流致振动分析工作的进展等。在完成这些研究工作的基础上,总结反应堆结构流致振动经验,探讨流致振动综合评价问题,最后对国内流致振动未来的研究工作进行展望。Abstract: This paper reviews the experimental research of flow-induced vibration（FIV） of several reactor structures completed in recent years, such as FIV test of reactor internals of Qinshan Phase Ⅱ, 1:5 model FIV test of reactor internals of ACP1000, and comprehensive vibration assessment plan for HPR1000 reactor internals. Comprehensive vibration assessment of these structures were carried out according to U.S. Nuclear Regulatory Commission R.G..1.20. Analysis methods of FIV are also described. The experiences of FIV research and assessment were accumulated. Finally, how to effectively assess FIV of reactor structures is discussed. Possible future work is prospected.
