Regional emergency evacuation system of nuclear power plant based on mobile positioning and radiation monitoring data

Abstract

The invention discloses an emergency evacuation system for a nuclear power plant area based on mobile positioning and radiation monitoring data, which mainly includes a radiation monitoring module, a radiation field reconstruction module, a communication module, a personnel positioning module and a data center. The invention obtains the radiation dose value of the monitoring point through the radiation monitoring module, calculates the three-dimensional distribution of the radiation field in the nuclear power plant area according to the radiation dose value of the monitoring point, obtains the personnel position in the nuclear power plant area through the personnel positioning module, and formulates the nuclear accident situation based on the above information. The emergency evacuation plan for the nuclear power plant area, assisting the nuclear power plant in nuclear emergency work. The system can be used for public emergency evacuation in the nuclear power plant area and the nuclear emergency plan area where it is located, and supports emergency management and decision-making outside the nuclear accident site. Compared with the traditional nuclear emergency evacuation system, the present invention can more accurately locate the position of the personnel to be evacuated and the radiation field distribution in the area where they are located, and realize precise evacuation with known dose, so the emergency evacuation strategy formulated is more scientific.

Description

technical field [0001] The invention relates to the field of nuclear power plant radiation protection and accident emergency response, in particular to an emergency evacuation system for a nuclear power plant area based on mobile positioning and radiation monitoring data. Background technique [0002] When a nuclear accident occurs, the reactor will release radionuclides, and the radionuclides migrate and spread in the nuclear power plant area and even the environment, causing radiation hazards to the surrounding personnel. Nuclear emergency refers to emergency actions different from normal order and normal working procedures to control or mitigate nuclear accidents and reduce the consequences of nuclear accidents. Nuclear emergency evacuation is the act of moving people from the nuclear accident area to a relatively safe area in order to reduce the radiation dose hazards suffered by the personnel in the nuclear accident area. Nuclear emergency evacuation is different from ...

Problems solved by technology

[0005] In addition, in the process of nuclear emergency evacuation, the control of the accident scene by the emergency command personnel and the interaction with the personnel to be rescued are also important guarantees to ensure the smooth operation. The traditional emergency evacuation process relies heavily on the usual drills to ensure the order of emergency evacuation, and it is difficult to carry out on-site operations.
