NUCLEAR POWER PLANT LEAKAGE MONITORING ALARM METHOD AND ALARM SYSTEM

摘要

The present invention is used in the technical field of nuclear power, and provides a nuclear power plant leakage monitoring alarm method, comprising: acquiring a unit operating condition signal and, on the basis of the unit operating condition signal, determining leakage monitoring availability; if leakage monitoring is in an available state, then acquiring a processing system state signal and leakage monitoring instrument data, and determining whether the leakage monitoring data is reliable; if the leakage monitoring data is in a reliable state, then implementing leakage source positioning analysis and leakage source quantitative calculation; if the diagnostic results of the leakage source positioning analysis and the leakage rate quantitative calculation both show that a leak has occurred, and leakage response characteristics are met, then triggering a leakage alarm. Also provided in the present invention is a nuclear power plant leakage monitoring alarm system. The present invention can effectively increase the accuracy of leakage monitoring and reduce operator intervention, thereby reducing human factor faults and increasing the level of automation of leakage monitoring.
