Abstract: The optimization and application of a domestic online sipping device are described in this paper. By optimizing and resetting key parameters, analyzing the threshold counting rate data in the form of chart, using 241Am radioactive source to help locate the 81 keV position, we optimized the device state and sought out the failed fuel elements successfully during refueling outages.

Key words: Online-sipping, Failed fuel elements, NaI detector
