Abstract: Background count rate deducted LaBr₃:Ce scintillator was used to detect ¹⁶N. Results show a better detection efficiency and energy resolution of it, enabling full energy area detection thusly. An alert level of leakage was added that decreases the steam generator's threshold of leakage alarm. The function of count rate and energy spectrum integration is supplemented after alarming to display the real time leakage progress. Leakage simulation is achieved at different levels through slow and fast motion play of screen recording.
