模型驱动的小型模块化自然循环铅基快堆早期功能设计与验证OA

The traditional document-based nuclear power equipment development pattern had prob-lems such as discrete and poorly correlated design information,ambiguous design intentions that were diffi-cult to trace,and a lack of intuitiveness and immersion in the design argumentation processes.Taking the small and modular natural circulation lead-based fast reactor(NCLFR)as the research object and taking the assembly and disassembly processes as an example,the MBSE method was combined with the virtual pro-totype technology,and three aspects of requirement analysis,functional design,and functional verification were discussed.Based on the independently developed MBSE modeling platform M-Reactor in the China Nuclear Power Technology Research Institute Co.,Ltd.,the requirement analysis and functional design of the assembly and disassembly processes were carried out.On the basis of the early 3D modeling of the NCLFR,the consistent mapping and model linkage between the system logic model and the functional vir-tual prototype were achieved,verifying the completeness,correctness,and traceability of the assembly and disassembly processes,providing designers with a more immersive design experience and a visual design verification method.In this way,the results may provide a reference for the applications of the MBSE method in the systematic design of nuclear power equipment.
