Development And Application Of Thermal Analysis Software Evaluation Database Platform For Nuclear Power Plant

In the process of nuclear energy development,nuclear safety is the top priority,and nuclear power design and analysis software is the prerequisite to ensure nuclear safety.An important and critical step in the process of nuclear power design and analysis software development is to verify and evaluate the software model using test data.(Evaluation model development and evaluation process)EMDAP method is an internationally advanced evaluation model development and evaluation method,which relies on a large number of experimental data sufficient to cover major physical phenomena.A evaluation database which can be used for nuclear power software model verification and evaluation can ensure the completion of EMDAP method and greatly support the development,verification and evaluation of nuclear power software.In the world,there is a lot of verification and evaluation data for nuclear power design and analysis software,but a lot of test data are not open to our country,so it is necessary to establish a evaluation database platform with independent intellectual property rights.Firstly,this paper analyzes the characteristics and logic of the test data in the field of nuclear power,designs a data processing scheme,and processes the data according to this scheme.Then according to the requirements analysis of the main problems of verification and evaluation in the development of nuclear power design and analysis software,the evaluation database platform of the nuclear power plant thermal analysis software model is designed and implemented.After the platform is developed,the platform is tested and applied.The design data processing scheme is extraction scheme and storage scheme.The data extraction scheme is successively designed as project,facility,test and working condition extraction scheme from the top layer to the bottom layer,and the storage scheme is designed as project and facility storage scheme.After the data processing is completed,a unified format can be formed,which provides the data foundation for the evaluation database platform.The database platform adopts B/S architecture,Mongo DB background database,and uses EMDAP method,E-R diagram,hierarchical diagram and flow chart to design,ensuring the accuracy and efficiency of the platform.At the same time to the system management,audit management,data management,query,display,evaluation matrix,recycling station management 7 key modules specific design and put forward the implementation path,and finally form an overall design scheme.At the end of the design and development of the platform,the black box test method was used to carry out the black box test on the platform,and then the platform was applied.The test and application results show that the evaluation database platform of the thermal analysis software for nuclear power plant meets the design requirements.In this paper,the design of nuclear power plant thermal analysis software evaluation database platform has greatly improved the usability and convenience of data,carried out integration innovation on large-scale test data,and reached the international advanced level in data integrity and data coverage,which can provide reliable and comprehensive test data for all kinds of nuclear power software confirmation and model evaluation.Will contribute to the autonomous development of nuclear power software of our country.
