Abstract
This paper mainly introduces the research practice of removing radiation hot spots deposited in the primary coolent system lines by ultrasonic on-line decontamination process in NPP.In this study,ultrasonic power of 60 W and 100 W were applied to the decontamination practice of 26.7 mm and 88.9 mm lines,respectively.The practice shows that the efficiency of on-line hot spot removal by ultrasonic can reach 60％-70％,which is more obvious than that by conventional flushing process.At the same time,this research shows that the application of ultrasonic on-line decontamination needs to consider the factors such as on-site working environment,ultrasonic power,medium flow rate and radionuclide deposition mode comprehensively,so as to make it achieve a better application effect.关键词
