Problems solved by technology

[0004] This field is currently focusing more on the optimization and analysis of the radiation protection actions of the surrounding public after the nuclear accident, and the action plan for emergency rescue personnel (such as emergency repair personnel, radiation monitoring personnel, decontamination personnel, medical rescue personnel, etc.), Little attention has been paid to radiation protection, and there is a lack of methods and tools that can quickly and effectively optimize the analysis of emergency action plans

Embodiment 1

[0105] The accident emergency decision-making optimization function module realizes the optimal analysis, evaluation and calculation of countermeasures according to the specific accident consequences, interface requirements, data format and overall task requirements. It mainly includes two functions:

[0106] 1) Retrieve the results of upstream meteorological analysis and dose field analysis modules, and present the relevant results of expected dose and preventable dose according to the early radiation protection measures to be adopted by different personnel, and conduct Prioritize the radiation protection measures, generate radiation protection countermeasures for emergency workers according to the results of the upstream analysis module, provide decision support, and complete the information storage of the results.

[0107] 2) Take the specific value of the accident consequences and parameters such as the route to be selected and time point as input, and extract the route in...

Embodiment 2

[0141] prerequisite

[0142] For a complete test case, add the test case and start analysis command in server_simulate.py, and store the case definition input file and the atmospheric concentration field result file in the FTP path specified in the start analysis command.

[0143] Test target:

[0144] The result files generated by the calculation of the test emergency rescue operation module meet expectations. The optimization evaluation results of the emergency rescue action plan will be saved to a file named .json is a special case output file, which also saves the calculation results of the action radius of each protection action plan of the public protection module.

[0145] The result file also contains a calculation completion flag field, with "outJudgement" set to true if the calculation was completed successfully, or false if the calculation was aborted.

[0146] prerequisites:

[0147] For a complete test case, add the test case and start analysis command i...

Embodiment 3

[0175] Such as image 3 As shown, after the input conditions are given (the user selects the entry and exit paths), the specific workflow is as follows:

[0176] Calculate the cumulative dose into the route;

[0177] Obtain the specific moment of arrival at the scene;

[0178] Calculate the cumulative dose of the evacuation route according to the evacuation route and time;

[0179] According to the cumulative dose corresponding to the entry route, withdrawal route, and on-site stay, measure the relative size of the personal cumulative dose limit;

[0180] According to the comparison results, the iterative calculation of the residence time is performed:

[0181] When the dose is lower than the limit value, increase the on-site stay time, and calculate the cumulative dose of entry, exit and stay again;

[0182] When the dose is higher than the limit value, reduce the on-site stay time, and calculate the cumulative dose of entry, exit and stay again;

[018...

Abstract

The invention belongs to the technical field of public nuclear safety, and discloses a nuclear accident emergency rescue action optimization analysis method and analysis system. A plurality of emergency rescue action schemes are optimized according to a front-end radiation field calculation result and formulated emergency action schemes (given emergency personnel departure time, advancing routes and withdrawing routes plotted in a GIS, adopted protective measures and taken traffic tools), and the most reasonable action scheme suggestions are given. According to the method, targeted emergency protection measure analysis and evaluation can be realized according to different elements of an evaluation target, such as various compositions of related measures and related personnel of various types of accidents. Thus, the dose evaluation analysis function of corresponding countermeasures or measures can be completed within the time specified by the system, and an accurate analysis result can be obtained. All the modules are scientifically designed and realized, and efficiently and cooperatively run.

Description

technical field [0001] The invention belongs to the technical field of public nuclear safety, and in particular relates to an evaluation method and an evaluation system for nuclear accident emergency countermeasures. Background technique [0002] At present, nuclear emergency decision-making is the basis of emergency response to nuclear power plant accidents. At present, a lot of research has been carried out on the emergency decision support technology of nuclear accidents, and some nuclear emergency decision support systems have been developed with model prediction as the main function, among which the real-time online decision support system (RODOS) in Europe is more representative. NARAC, the National Atmospheric Release Decision Support Capability System of the United States, and WSPEEDI, the Worldwide Environmental Emergency Dose Information Prediction System of Japan. Existing emergency decision support systems are all based on the results of simulation calculations ...
