In order to realize the quantitative and location detection of heat transfer tube leakage,the helium leak detec-tion acquisition and analysis software of steam generator heat transfer tube is developed by using C/S architecture com-bined with database technology and WPF presentation technology in this paper.According to the leakage characteristics of the heat transfer tube,the leakage location formula was optimized from the perspective of time and flow.In order to verify the reliability of the algorithm,leak quantification and location tests were carried out.The test results show that the average leakage quantification error range is less than±0.2 N·cm3·h-1.The average location error range before the leak location for-mula is optimized is less than±1.0 m,and the average location error range after the leak location formula is optimized is less than±0.3 m.The developed helium leak detection acquisition and analysis software can meet the quantitative and po-sitioning requirements of helium leak detection of steam generator heat transfer tubes.
