Graded management method for equipment of nuclear power plant

Abstract

The invention provides a graded management method for equipment of a nuclear power plant, and relates to a graded management for equipment. The graded management method comprises the following steps of performing key degree grading on the equipment, thereby dividing to key equipment, important equipment and common equipment; performing equipment working environment grading for dividing to harsh and good; performing equipment working efficiency grading for dividing to high and low; performing equipment maintenance window determining for dividing to an online mode and an offline mode; and makinga maintenance plan. According to the graded management method, through performing key degree grading, environment grading, frequency dividing and equipment maintenance window determining on the equipment of the nuclear power plant, an equipment grading result can be quickly applied in equipment graded management, thereby greatly simplifying making and application of a maintenance strategy, and greatly improving equipment management efficiency. Through performing grading management on the equipment, the graded management method realizes advantages of ensuring sufficient importance of the key equipment, realizing reasonable and scientific resource distribution, standardizing equipment management operation, and saving a large amount of manpower and material resources.

Description

technical field [0001] The invention relates to a hierarchical management method for equipment, in particular to a hierarchical management method for nuclear power plant equipment. Background technique [0002] There are a lot of equipment in nuclear power plants, and the number of equipment in one unit alone reaches 50,000 to 70,000. However, the functions of each equipment and the contribution to the safe power generation of nuclear power plants are not exactly the same. If each equipment is equally invested in management It will not be possible to achieve efficient and reasonable equipment management, and it will also be impossible to improve the operational reliability of nuclear power plant equipment. According to historical statistics, outage events caused by equipment problems account for more than 80% of the total. One of the important reasons is the lack of unified and reasonable equipment classification, and the focus of equipment management is not prominent. Ther...
