摘　　要：秦山三期CANDU-6反应堆为卧式管道型重水堆,采用主热传输支管(Feeder管)传输流经堆芯的冷却剂。Feeder管在运行过程中会不断遭受腐蚀而导致壁厚减薄。Feeder管超声检查技术在国内仍不完善,技术支持处深入分析检查难点,开发Feeder管超声检查技术,并对大修检查数据进行分析,评估得到Feeder管的使用寿命满足使用要求。In the CANDU-6 nuclear reactor,fuel channels adopt a horizontal layout.The feeder pipes connect with both ends of each pressure pipe to transport the coolant.With the reactor operation,the feeder pipes will be corroded.The technical support department developed the ultrasonic inspection technique,analyzed the inspection data,and evaluated the service life of the feeder.
