摘要
池式钠冷快堆的控制棒驱动机构具有细长、结构非线性和多激励点等特征,因此其抗地震性能鉴定问题一直受到世界发展快堆国家的重视。介绍了在竖井式多点激励地震台上所完成的对中国实验快堆(简称CEFR)控制棒驱动机构的抗震鉴定试验。试验结果表明,该型控制棒驱动机构的功能完好性和结构完整性满足设防地震下的规范要求。
The structure of the control rod drive mechanism in pool type sodium-cooled fast reactor is the characterized by long, thin, and geometric nonlinearity, and the seismic load is multiple activation. The anti-seismic evaluation is always paid great attention by the countries developing the technology worldwide. This article introduces the seismic appraisal test of the control rod drive mechanism of China Experimental Fast Reactor （CEFR） performed on a activation. The result of the control rod drive mechanism seismic platform which is vertical shaft style and multiple test shows the structural integrity and the function of the could meet the design requirements of the earthquake intensity.
