On application of MBSE in nuclear engineering design

This article explains the connotation and value of MBSE, and investigates the practice and application of MBSE by foreign nuclear power R&D enterprises. A case study of the MBSE implementation process for the passive safety system of nuclear power project is conducted, with the main contents including application of requirements analysis, functional analysis, and architecture definition in passive safety system design. The system model is used to express system requirements, structure, parameters, and behavioral information to achieve traceability and verification of various information in the system design process, improve design efficiency, and reduce design risk. The article also explores the guiding role of the MBSE method in nuclear power R&D and design, and then the innovation of nuclear power engineering R&D design mode to provide a feasible solution for digital transformation. According to the practice and understanding of MBSE, challenges faced by MBSE involving technology, culture, thinking and management are discussed in order to provide a reference for further application of MBSE concept in nuclear power design.
