Method for integrating engineering analysis software in nuclear power simulation system and nuclear power simulation system

Abstract

The invention discloses a method for integrating engineering analysis software in a nuclear power simulation system. The method is characterized by comprising the following steps of creating a data exchange mechanism, to be more specific, establishing an interface variable of the engineering analysis software and a first call function of the interface variable, and performing data exchange through the interface variable; creating a synchronous operation mechanism: establishing a marking variable, a calling period and a second calling function for calling the engineering analysis software, and judging whether calling the engineering analysis software is performed for the first time or not to enter an engineering analysis calculation stage. The invention further discloses the nuclear power simulation system. By means of the method for integrating the engineering analysis software in the nuclear power simulation system and the nuclear power simulation system, accuracy and credibility of nuclear power simulation can be improved.

Description

technical field [0001] The invention relates to the field of nuclear power simulation, and more specifically relates to a method for integrating engineering analysis software with a nuclear power simulation system and a nuclear power simulation system. Background technique [0002] In nuclear power plant simulation, the nuclear power simulation system itself can perform engineering analysis and calculation, but the analysis and calculation programs of the nuclear power simulation system are often inferior to independent engineering analysis programs in terms of accuracy and depth. For example, the nuclear power simulation system itself usually includes a thermal-hydraulic calculation program. However, compared with the industry-recognized and specialized RELAP5 thermal-hydraulic calculation software, the thermal-hydraulic calculation program in the nuclear power simulation system has a higher calculation range and There is still some gap in accuracy.

Problems solved by technology

[0002] In nuclear power plant simulation, the nuclear power simulation system itself can perform engineering analysis and calculation, but the analysis and calculation program of the nuclear power simulation system is often not as accurate and deep as the independently operating engineering analysis program

For example, the nuclear power simulation system itself usually includes a thermal-hydraulic calculation program. However, compared with the industry-recognized and specialized RELAP5 thermal-hydraulic calculation software, the thermal-hydraulic calculation program in the nuclear power simulation system has a higher calculation range and There is still some gap in accuracy

[0003] If you want to use RELAP5 thermal-hydraulic calculation software in the nuclear power simulation system to perform thermal-hydraulic simulation calculations, there are problems in time synchronization, control synchronization, data exchange, and reset operation that need to be coordinated. Therefore, the nuclear power simulation system uses the existing Some engineering analysis software (such as: RELAP5 thermal hydraulic calculation software) has certain technical difficulties in simulation calculation
