Device and method for abnormal diagnosis of sodium ion index in sewage system of nuclear power plant

Abstract

The invention discloses a diagnosis device and method for abnormity of a sodium ion index in a sewage system of a nuclear power plant, and relates to the field of diagnosis of abnormity of the chemical indexes of a secondary loop of the nuclear power plant. The device comprises a sodium analyzer, a first positive conductivity analyzer, a second positive conductivity analyzer, a pH value analyzer, a first data acquisition module, a second data acquisition module, a third data acquisition module, a fourth data acquisition module, an analysis indicating module and a fault recording module, wherein the first data acquisition module is connected with the sodium analyzer, the second data acquisition module is connected with the first positive conductivity analyzer, the third data acquisition module is connected with the second positive conductivity analyzer, the fourth data acquisition module is connected with the pH value analyzer, and the analysis indicating module is respectively connected with the first data acquisition module, second data acquisition module, third data acquisition module, fourth data acquisition module and fault recording module. The diagnosis device and method can effectively improve the efficiency and accuracy in diagnosis of the sodium ion index in the sewage system of 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 sodium ion indicators in a sewage system of a nuclear power plant. Background technique [0002] At present, when the sodium ion 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 pro...
