Method for realizing simulation function of serious accident analysis and calculation program of nuclear power plant

Abstract

The invention discloses a method for realizing the simulation function of the serious accident analysis and calculation program of a nuclear power plant. The method comprises the following steps that:analyzing a MELCOR source program to parse a part which needs to be integrated, carrying out data interaction through a data interaction mechanism; and according to the data interaction mechanism, packaging different data interaction interfaces underdifferent working conditions, and realizing the multi-working-condition simulation function of the serious accident analysis and calculation program.Compared with the prior art, the method disclosed by the invention avoids various uncertainties caused by a great quantity of interface definitions when the simulation function of the serious accident analysis and calculation program is realized in the prior art, a workload is reduced, error risks on an aspect of interface variable definition due to the adoption of an EQUIVALENCE variable equivalence function are avoided, in addition, the dereferencing accuracy of a final calculation result is guaranteed, and universality is enhanced.

Otherwise, the EQUIVALENCE statement in the source program will be invalid

Therefore, the code characteristics of the source program of the severe accident analysis calculation program developed in the FORTRAN language make its data interaction mechanism more difficult to implement, and there is a risk that the calculation logic of the source program will be changed due to incomplete analysis, and the calculation results will be distorted.

[0010] When realizing the above-mentioned second scheme, in the source program of MELCOR, due to the different input cards, the number and meaning of the defined program package calculation data variables will also be different, resulting in different values ​​of the program package index variables , so this method realizes the severe accident analysis calculation program MELCOR, which has poor versatility in data interaction, and the interface variable names with large arrays and index numbers are poorly readable, which is not conducive to user experience
