Method for displaying evaluation data of nuclear radiation aftermath

Abstract

The invention discloses a method for displaying the evaluation data of a nuclear radiation aftermath. A radioactive release source item is analyzed and calculated according to the state of the power plant of a nuclear power station, an accident aftermath which is possibly generated after an accident occurs to the nuclear power station is forecasted and calculated according to a quick evaluation mode, a single-module mode and a fine evaluation mode, and the calculated aftermath evaluation result is written into a text file; then, these text data are respectively classified according to three modes of the quick evaluation mode, the single-module mode and the fine evaluation mode, are written on a corresponding grid chart layer of a selected mode by selecting and switching at least one mode in the three modes and are represented in the form of arrowheads with different colors and/or changes. The invention combines the parameter information of the geography, the population, the weather and the like around the nuclear power station and intuitively reflects the aftermath which is possibly caused after the accident occurs to the nuclear power station.

Description

technical field [0001] The invention relates to a method for evaluating consequences of emergency accidents, in particular to a method for displaying nuclear radiation consequence evaluation data. Background technique [0002] With the rapid development of nuclear energy and nuclear technology applications in China, my country currently has 11 nuclear power units in operation, 17 civilian research reactors in service, and nuclear facilities supporting nuclear power are also at the peak of construction. Nuclear energy occupies an increasingly important position in my country's economy and energy production, and the tasks of nuclear safety and radiation environmental safety management are becoming increasingly heavy. Therefore, it is increasingly urgent to strengthen the emergency management of nuclear accidents, grasp the emergency situation and related information of nuclear accidents in a timely, accurate and comprehensive manner, so as to organize and coordinate the requir...

Problems solved by technology

[0005] However, the functions realized by the Tianwan rapid evaluation system are relatively simple. The rapid evaluation calculation is only carried out for the Tianwan Nuclear Power Plant, and it can only display atmospheric diffusion, dose and intervention actions.

Atmospheric diffusion is mainly used to display the air time-integrated concentration, ground dry deposition concentration and ground wet deposition concentration of the selected nuclide during calculation; the dose is displayed for the inhalation dose results of the two effective organs and the thyroid gland; intervention actions It is used to display the evacuation area, concealment area and deterministic effect area; the display method is to use gradient colors to indicate the numerical value on the 41×41 grid around the nuclear power plant. The above display system can only display the geographic information and accident consequences around a certain nuclear power plant Information; the data is only displayed in the form of a grid diagram, the effect is not realistic, and the display speed is slow; there is a lack of visual display of wind speed and direction of the wind field data around the power station; there is a lack of dynamic display of meteorological data and radiation monitoring data around the power station
