Nuclear power station power-losing accident analysis method and system

Abstract

The invention discloses a nuclear power station power-losing accident analysis method and system. The nuclear power station power-losing accident analysis method includes the steps of detecting whether a power source of each nuclear power station safety system device is available or not, analyzing whether each nuclear power station safety system device is available or not if the power source of each nuclear power station safety system device is available, and judging that a nuclear power unit does not have power-losing accidents if each nuclear power station safety system device is available. According to the nuclear power station power-losing accident analysis method, whether the power source and the functions of each nuclear power station safety system device are available or not is detected to further judge whether the nuclear power unit has the power-losing accidents or not, nuclear power station safety protection requirements are effectively met, and the defect that the method that a manual failure tree is used for conducting accident analysis is low in efficiency is solved. In addition, the invention further discloses the nuclear power station power-losing accident analysis system.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a method and system for analyzing power failure accidents of nuclear power plants. Background technique [0002] In the design of nuclear power plants, it is necessary to analyze the design basis accidents, and the power failure accident conditions of nuclear power plants must be considered. The pressurized water reactor nuclear power plant is mainly composed of three parts: the pressurized water reactor, the primary circuit system and the secondary circuit system. The nuclear fission is carried out in the reactor core composed of nuclear fuel in the pressure vessel. Fuel and light water are used as coolant and moderator. The heat released by nuclear fission is taken out of the reactor by the high-pressure water flowing through the primary circuit system in the reactor, and the heat is transferred to the water in the secondary circuit in the ...
