Description

Technical field [0001] The invention relates to the field of diagnosis of abnormal chemical indicators of the secondary circuit of a nuclear power plant, in particular to a device and method for diagnosing an abnormality of positive conductivity indicators of a condensate system in a nuclear power plant. Background technique [0002] At present, when the positive conductivity index of the condensate system of a nuclear power plant unit deviates from the technical specifications, it is usually handled according to the experience of the chemical professionals and 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 nuclear power plant secondary circuit indicator diagnosis technology, chemical staff with rich experience is relatively scarce; on the other hand, staff generally refer to specific operating procedures for related abnormalities. However, t...
