Device and method for diagnosing abnormality of ph value index in sewage system of nuclear power plant

Abstract

The invention discloses an abnormity diagnosis device and method for a pH value index of a sewage discharge system in a nuclear power plant, and relates to the field of chemical index abnormity diagnosis for a secondary loop in the nuclear power plant. The device comprises a pH table, a gamma specific activity table, a first data acquisition module and a second data acquisition module, wherein the first data acquisition module is connected with the pH table, and the second data acquisition module is connected with the gamma specific activity table, the device further comprises an analysis indicating module and a fault recording module, the analysis indicating module is connected with the first data acquisition module, the second data acquisition module and the fault recording module respectively, the pH table is used for carrying out online detection of the pH value of APG, the gamma specific activity table is used for carrying out online detection of the total gamma specific activity of APG, the first data acquisition module is used for acquiring the pH value and sending the pH value to the analysis indicating module, and the second data acquisition module is used for acquiring the total gamma specific activity and sending the total gamma specific activity to the analysis indicating module. The abnormity diagnosis device and method for the pH value index of the sewage discharge system in the nuclear power plant disclosed by the invention can effectively improve the efficiency and the accuracy for diagnosing the pH value index of the sewage discharge system in the nuclear power plant.

Description

technical field [0001] The invention relates to the field of abnormal diagnosis of chemical indicators of a secondary circuit of a nuclear power plant, in particular to a device and method for diagnosing abnormal pH value indicators of a sewage system of a nuclear power plant. Background technique [0002] At present, when the pH value index of the sewage system of the nuclear power plant unit deviates from the technical specification, it usually relies on the experience of chemical professionals and handles it according to the relevant operating procedures of the power plant. The country is currently vigorously developing nuclear power, and there are more and more nuclear power plants. However, in terms of diagnostic technology for the secondary circuit indicators of nuclear power plants, there is a relative shortage of chemical staff with rich experience; However, the actual conditional factors are often inconsistent with the preconditions required by the operating procedu...
