A calculation method and system based on a serious accident numerical simulation optimal practice guide rule

Abstract

The invention provides a calculation method and system based on a serious accident numerical simulation optimal practice guide rule, and the method comprises the steps: building an operation interface, and importing a calculation task initiated by a first type of user into the operation interface, so as to display the specific demand information of the calculation task; Corresponding condition information input into the operation interface by the second type of users according to the specific demand information of the calculation task is sent to the first type of users, so that the first typeof users can check the condition information, and after the check is passed, a check confirmation instruction is sent to the second type of users; And inputting a command line file which is issued bya second type of user according to the auditing confirmation instruction and corresponds to the calculation task into the operation interface, so that the operation interface associates the command line file with the condition information to obtain a target calculation strategy, and performing corresponding calculation according to the target calculation strategy. The method can effectively calculate and analyze serious accidents on the basis of the optimal practice guide rule, and improves the calculation efficiency and availability.

Description

technical field [0001] The invention relates to the technical field of severe accident analysis and numerical simulation, in particular to a calculation method and system based on best practice guidelines for numerical simulation of severe accidents. Background technique [0002] A serious accident in a nuclear power plant refers to a series of phenomena caused by the fact that under extreme conditions, the reactor is not effectively cooled, the temperature is too high and it melts, and radioactive substances are released into the pressure vessel. For serious accidents, a large number of mechanism analysis, preventive measures analysis and mitigation measures research should be carried out. In addition, since any preventive measures and mitigation measures cannot guarantee 100% that the core meltdown and containment failure will not result in a large amount of radioactive release, therefore, in-depth research on the mechanism and causes of serious accidents and application o...

AI Technical Summary

Problems solved by technology

In the field of computer simulation, due to the complexity of the modeling and calculation process, there are many parameters involved, and a variety of assumptions are usually introduced, and the calculation usually takes a lot of time. If the appropriate method and parameters cannot be selected as soon as possible, it will take a lot of money. time for trial calculation

Even if a relatively reasonable result is obtained through trial calculation, it still needs to be compared and verified with relevant experimental data, and the calculation is corrected in turn and iterated continuously, resulting in low calculation efficiency and low usability.
