Nuclear power plant steam generator leakage diagnosis method

Abstract

The invention discloses a nuclear power plant steam generator leakage diagnosis method. The method comprises the steps of: performing real-time data acquisition and extraction of water-phase dissolvedoxygen of a steam generator; collecting and extracting real-time data of vapor-phase dissolved oxygen of the steam generator; acquiring and extracting real-time data of high-pressure water supply dissolved oxygen; determining whether the leakage index of the steam generator is abnormal or not and an abnormal level; and analyzing equipment and reasons causing leakage of the steam generator. According to the invention, the leakage abnormality of the primary side and the secondary side of the nuclear power plant steam generator can be diagnosed, the fault type is determined, and measures are suggested to eliminate faults, so that the safety of nuclear power primary and secondary loop systems is improved, and the stable and safe operation of the whole nuclear power plant is ensured.

Description

technical field [0001] The invention relates to the field of operation safety of steam generator (SG, Steam Generator) equipment in a nuclear power plant, in particular to the diagnosis of leakage from the primary side to the secondary side of the steam generator in the nuclear power plant. Background technique [0002] Nuclear power is a safe, reliable, economical, and environmentally friendly energy source. Many countries are vigorously developing nuclear power; however, nuclear power plants are a complex system that involves multiple professional fields and requires the cooperation of multiple departments to ensure the normal operation of nuclear power plants. ; and with the acceleration of the construction of nuclear power plants, the professional and technical personnel of nuclear power plants are scattered, and the new technical personnel have no practical experience, and the ability to judge the abnormality of nuclear power plants is insufficient, and the guarantee for...

AI Technical Summary

Problems solved by technology

[0004] In order to ensure the safe operation of nuclear power plants, many achievements have been published, such as neural network, genetic algorithm, fuzzy logic and other methods have been applied in the field of fault and abnormal diagnosis of nuclear power plants, and have achieved certain practical results; and the above methods are due to There is a certain risk of misdiagnosis due to high requirements for basic data, so the application and development of the above methods in the field of nuclear power fault and abnormal diagnosis are subject to certain restrictions
