Embodiment Construction

[0040] In order to have a clearer understanding of the technical features, purposes and effects of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] The main idea of ​​the present invention is to first sort out the affected systems under different temporary stop modes, and analyze which equipment operating frequency and operating environment in the system have changed; then according to the criticality, operating frequency, and operating environment of these equipment Comprehensively consider the dimensions to screen out the affected equipment list; finally, classify and summarize the sorted out equipment list according to the equipment category, and finally design an ide...

Abstract

The identification method for the equipment affected by the long-term temporary shutdown of nuclear power units includes the following steps: S1. sort out the systems affected by the temporary shutdown; S2. analyze the operating frequency of the system and the equipment whose operating environment has changed; S3. For the analyzed equipment, comprehensively consider the three dimensions of equipment criticality, operating frequency, and operating environment to screen out the affected equipment list; S4, classify and summarize the equipment list sorted out in S3 according to the equipment category. The invention provides a comprehensive identification method and means for changes in the operating frequency and operating environment of the equipment due to the impact of the temporary stop.

Description

technical field [0001] The invention belongs to a method for identifying equipment affected by a long-term temporary stop of a nuclear power unit. Background technique [0002] As the domestic power market environment is becoming increasingly severe, the availability of nuclear power units has declined, and nuclear power units are often temporarily shut down or even used for medium and long-term standby. There have been many incidents of equipment damage caused by long-term temporary shutdown of nuclear power units in operation by CGNPC. According to the analysis and feedback of the incidents in the power plant, the preventive maintenance strategy of some equipment cannot meet the maintenance needs of long-term shutdown equipment, resulting in a decline in the reliability of this part of equipment. At the same time, due to the lack of technical research and reserves for the long-term temporary shutdown of the unit, it appears to be inexperienced in dealing with the challenge...
