Embodiment Construction

[0059] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0060] Taking the system reliability evaluation of the cooling water system of a certain nuclear power plant equipment as an example, the implementation process of the method of the present invention is described in detail. The system reliability evaluation method, such as figure 1 shown, including the following steps:

[0061] Step S1: Decompose the functional structure of the equipment cooling water system of the nuclear power plant; the equipment cooling water system exchanges heat with the plant water system through the heat exchanger, thereby taking out the heat dissipation of the nuclear island equipment and ensuring the safety of the nuclear island equipment. The equipment cooling water system includes two pumps, two heat exchangers, an expansion tank, monitoring devices (temperature, flow detection) and related pipes and...

Abstract

The invention belongs to the technical field of system reliability analysis and design, and particularly discloses a nuclear power equipment system reliability assessment method, which comprises the following steps: firstly, carrying out fault mode and influence analysis on equipment according to functional structure decomposition and related fault information of nuclear power equipment; establishing a fault tree model of the equipment based on a fault tree analysis method; then, establishing a reliability prediction and distribution model of the equipment; establishing a reliability analysismodel considering common cause failure; On the basis of previous analysis, after maintenance factors in the service period are considered, a maintenance strategy analysis model based on reliability isestablished to formulate a periodic maintenance strategy; and finally, based on a human factor engineering simulation platform, establishing an equipment inspection and maintenance simulation model to analyze a specific inspection and maintenance process. The model established by the invention can provide important reference and guidance for actual nuclear power equipment design, operation, maintenance planning and the like.

Description

technical field [0001] The invention belongs to the technical field of system reliability analysis and design, and in particular relates to a system reliability evaluation method for a nuclear power plant equipment cooling water system. technical background [0002] Compared with traditional energy and other renewable energy, nuclear power is a renewable energy that can be supplied continuously and stably on a large scale. The development of nuclear power plays an important role in the realization of my country's energy structure adjustment, energy conservation and emission reduction, and smog control. However, there are huge potential risks in the nuclear power industry. Once an accident occurs in the production, transportation and power generation of nuclear fuel, not only will the harm be fatal, but it will also cause major social impact. Therefore, for the equipment system in each link of the nuclear power industry, its safe operation and reliability evaluation are the ...
