摘　　要：针对传统的铅冷快堆非能动余热排出系统设计中存在开发效率低、迭代周期长、模型二义性等前期需求问题,本研究将基于模型的系统工程(Model-based System Engineering,MBSE)方法应用于铅冷快堆非能动余热排出系统设计需求中,结合设计流程进行系统架构的初步设计,该系统架构由需求分析、功能分析和设计综合三部分组成。结果表明:需求分析阶段生成的需求图和用例图可捕获系统需求并确定系统顶层用例;功能分析阶段绘制的时序图、活动图和状态机图可形成系统功能模型并提供早期确认与验证;设计综合阶段建立的白盒模型最终实现系统架构的分析与设计。采用该方法设计的系统架构可确保前后设计需求一致性,进一步降低设计风险并提高设计效率,可为数字化铅冷快堆非能动余热排出系统设计与优化提供应用参考。[Background]Traditional text-based system engineering in the design and application of passive residual heat removal systems(PRHRS)for lead-cooled fast reactors has several requirement problems,such as low development efficiency,a long iteration cycle,and model ambiguity.[Purpose]This study aims to effectively address the aforementioned problems encountered in the PRHRS of lead-cooled fast reactors by adopting a model-based system engineering method.[Methods]The model-based system engineering(MBSE)method was preliminarily applied to the design requirement analysis of a PRHRS for lead-cooled fast reactors.During the design requirements study,the design process was combined with the preliminary design of the system architecture,comprising three parts:requirements analysis,functional analysis,and design synthesis.[Results]The generated requirement and use case diagrams describe the system requirements and determine the top-level use cases of the system in the requirement analysis stage.The time sequence,activity,and state machine diagrams form the system function model and provide early confirmation and verification in the functional analysis stage.Finally,the white box model realizes the analysis and design of the system architecture in the design synthesis stage.[Conclusions]The system architecture designed by this method ensures the consistency of the design requirements.In the future,it will further reduce the design risk,improve the design efficiency,and provide an application reference for the design and optimization of digital lead-cooled fast reactors'passive residual heat removal systems.
