Abstract

The invention is applicable to the technical field of nuclear power and provides a nuclear power plant leakage monitoring and alarming method. The nuclear power plant leakage monitoring and alarming method comprises the steps of obtaining a unit operating condition signal, and determining leakage monitoring availability according to the unit operating condition signal; acquiring a process systemstate signal and leakage monitoring instrument data to determine the reliability of the leakage monitoring data if the leakage monitoring is in an available state; executing leakage source localization analysis and quantitative calculation of a leakage source if the leakage monitoring data is in a reliable state; triggering a leakage alarm if diagnosis results of the leakage source location analysis and the quantitative leakage rate calculation indicate that leakage occurs and leakage response characteristics are met. In addition, the invention also provides a nuclear power plant leakage monitoring and alarming system. The accuracy of leakage monitoring can be effectively improved, the intervention of operating personnel is reduced, accordingly human-made faults are decreased, and the automation level of leakage monitoring is improved.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a nuclear power plant leakage monitoring and alarm method and an alarm system. Background technique [0002] The leakage of the primary circuit pressure boundary of the nuclear power plant reactor directly affects the safety of the nuclear power plant operation. The leakage of the application object of the leak-before-break technology directly affects the economical efficiency of the nuclear power plant operation. The leak monitoring system monitors the unidentifiable leaks at the pressure boundary of the primary circuit of the reactor and the leaks of the application objects of the leak-before-break technology. [0003] At present, the commonly used leakage monitoring method is through the alarm of a single monitoring instrument exceeding the threshold value. After the alarm, the operating personnel of the nuclear power plant will verify whe...
