A safety control method and device for a nuclear power plant

Abstract

The invention is applicable to the field of the safety of nuclear power, and provides a method and a device for safety control of nuclear power plants. The method comprises the following steps: according to authority information set by power plant area and corresponding to identification information of workers, work modes corresponding to time points asking for entering into the nuclear power plant area and corresponding relationship, corresponding to the work modes, of galleryful in a nuclear power plant area, judging whether to allow the workers to enter the specified nuclear power plant area; and when an emergency counting instruction is received, sending counting instruction successful receiving indication information, after a decision instruction of counting requesting information is received, adding one to the counted number, and according to information of the counted number of people and information of the number of people at a rally point, determining the number of missing persons. According to the method and the device, the number of people in a nuclear power plant area can be controlled in different modes, and the number of people in the nuclear power plant area can be counted accurately and efficiently, so that the safety guarantee of the workers is facilitated.

Description

technical field [0001] The invention belongs to the safety field of mega-kilowatt nuclear power, and in particular relates to a safety control method and device for personnel in a nuclear power plant. Background technique [0002] A nuclear power plant is a power plant that uses the energy released by nuclear fission or nuclear fusion reactions to generate electricity. It converts nuclear energy into thermal energy to heat water to generate high-pressure water vapor. After the water vapor enters the steam turbine through the pipeline, it passes The steam drives a steam turbine to generate electricity, converting mechanical energy into electrical energy. [0003] The energy generated in the nuclear reaction process is very huge. While the nuclear reaction process provides a large amount of heat energy, the hazards caused by improper operation and control are also very serious. Therefore, the safety during the production and operation of nuclear power plants must be strictly ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a safety control method for nuclear power plants to solve the problem that the site will be relatively chaotic under the emergency state of the prior art, the speed of the manual counting method is slow, and it needs to consume a long time in the counting process, and due to the existing The access control type authority control makes the number of personnel in the area unable to be effectively controlled, which is not conducive to ensuring the timely and effective evacuation of the staff, and is not convenient for ensuring the safety of the staff
