Nuclear emergency system of nuclear power plant

Abstract

The invention provides a nuclear emergency system of a nuclear power plant, and belongs to the technical field of nuclear power plant emergency planning and preparing. The system comprises portable individual emergency devices, a fixed nuclear radiation monitoring device, an emergency refuge and a control center. The portable individual emergency device and the fixed nuclear radiation monitoring device can position and measure current radiation data and send the data to the control center. The control center judges whether leakage happens or not, confirms the accident location and radiation range, and plans the retreating and emergency refuge route according to positions of all workers through summarization and analysis, and sends the information to the corresponding portable individual emergency devices to be displayed on a map through display modules, and safe retreating of the workers is ensured. The system is simple in structure, complete in function, rapid, efficient and high in safety coefficient, greatly improves nuclear emergency reaction capacity and increases the survival rate of the workers on site, and meanwhile can be used as a nuclear emergency command system of the nuclear power plant.

Description

technical field [0001] The invention relates to a nuclear emergency system of a nuclear power plant, which belongs to the technical field of emergency planning and preparation of nuclear power plants. Background technique [0002] With the continuous development and utilization of new energy sources, nuclear energy has gradually attracted widespread attention and application due to its green, clean, efficient and stable advantages. However, the safety issues of nuclear power plants have always troubled people. There has never been a nuclear accident in history without heavy losses. The impact is persistent and widespread. Nuclear accidents generally cause explosions, combustion, and radiation, causing great damage to the surrounding environment and people's physical and mental health. [0003] At present, early warning and personnel evacuation for nuclear accidents are generally limited to a single radiation measurement or require personnel to manually input environmental c...

Problems solved by technology

[0002] With the continuous development and utilization of new energy sources, nuclear energy has gradually attracted widespread attention and application due to its green, clean, efficient and stable advantages. However, the safety issues of nuclear power plants have always troubled people. There has never been a nuclear accident in history without heavy losses. Persistent and wide-ranging influence

[0003] At present, early warning and personnel evacuation for nuclear accidents are generally limited to a single radiation measurement or require personnel to manually input environmental conditions, and there are only fixed and pre-established escape routes. The notification method is generally through alarm bells or broadcasts. Judging the location of the accident visually or empirically cannot escape accurately and quickly

[0004] Moreover, when a nuclear leak occurs, it is often accompanied by concurrent explosions, combustion, smoke, etc., as well as damage to on-site equipment, resulting in the blockage of the original escape route, and the staff cannot obtain relevant information in a timely manner, and cannot make decisions in a short time. Correct judgment will lead to blind escape, which will also cause unnecessary casualties

At the same time, the control center cannot know the development of the accident on the scene, the distribution of personnel on the scene, casualties, etc., and cannot organize effective rescue in time, and cannot guarantee that the trapped people will be rescued in time

[0005] There is a related technology that establishes a network connection between the handheld measuring device and the control center. The Chinese patent "Nuclear Power Plant-Based Emergency Environmental Detection Method and System" (application number: 201410466587.5) proposes a method of using a portable measuring device to detect radiation, and in the radiation amount When the threshold is exceeded, the nuclear accident emergency system that reports to the command center wirelessly, although it can judge whether there is a leak through the amount of radiation, it cannot detect and judge the location of the leak and the range of radiation received in an all-round way, there is no emergency shelter, and it cannot The escape route given by the situation cannot guarantee the rapid and safe evacuation of personnel
