摘　　要：为清理田湾核电站1、2号机组蒸汽发生器(SG)二次侧排污穴室内积聚的腐蚀产物、降低其对壳体母材和焊缝造成腐蚀的风险,研制了排污穴室水力冲洗设备并且在机组大修期间进行了应用。通过水力冲洗工作,清理了SG排污穴室内积聚十余年时间的沉积物、检查确认排污穴室内壁和焊缝无异常,提高了蒸汽发生器运行的安全性、可靠性。In order to clean up corrosion deposits in the blowdown cave of secondary side of steam generators in Unit 1&2 of Tianwan nuclear power station and reduce its corrosion risk to base metal of shell and weld joints, a hydraulic flushing device was developed and applied during the outages. Through hydraulic flushing, the corrosion products accumulated in the blowdown cave of steam generators for more than ten years were cleared. The inside walls of the blowdown cave and the weld joints were checked and they are in good condition, which improved the operational safety and reliability of the steam generators.
