摘　　要：核电站反应堆控制棒组件在服役期间与导向架摩擦造成包壳管外表面磨损,对反应堆的安全运行造成极大隐患,严重时甚至可能引起核安全事故。利用控制棒包壳管超声和涡流检测信息提取信号特征值对其磨损状态进行评估,因单一特征信号反映的控制棒包壳管状态信息存在局限性,采用模糊数据融合方法对超声、涡流检测特征信号进行融合,获得更加全面、准确的包壳管磨损状态。实验结果表明,基于模糊数据融合的包壳管磨损状态评估比单一传感器对包壳管磨损状态评估更为可靠。Rod cluster control assembly of nuclear power plant rubs with the guide card,which may result in cladding wear during operation,even cause nuclear safety accidents.In this paper,the ultrasonic and eddy current examination were used to extract characteristic signal to evaluate the condition of cladding wear.The fuzzy data fusion method was applied to ultrasonic and eddy current characteristic signals so that the wear condition could be evaluated accurately.The experiment indicated,compared with the single signal identifying method,the evaluation method based on fuzzy data fusion can identify cladding wear condition reliably.
