摘　　要：反应堆保护系统是重要的核安全系统,其安全、可靠运行关系到整个核电装置的安全性。对新型核电装置而言,设计结构简单、集成度高、可靠性高的反应堆保护系统至关重要。区别于传统核电站反应堆保护系统设计,运用系统工程理论制定了适用于某新型核电装置反应堆保护系统的需求分析流程,并在此基础上捕获各方需求,形成系统的顶层设计要求。同时,介绍了基于具体事故场景的功能需求分析过程、非功能性需求分析要素以及设计约束分析要素,进而得出反应堆保护系统的功能架构设计,以指导后续的详细设计。该研究对其他仪控系统的设计也有较好的适用性和借鉴性。Reactor protection system is an important nuclear safety system,and its safe and reliable operation is related to the safety of the whole nuclear power plant.For new nuclear power device,it is crucial to design a reactor protection system with simple structure,high integration,and high reliability.Distinguishing from the design of reactor protection system in traditional nuclear power plants,a requirement analysis process applicable to the reactor protection system of a new nuclear power device is formulated by applying the system engineering theory,based on which the requirements of all parties are captured to form the top⁃level design requirements of the system.At the same time,the functional requirements analysis process based on specific accident scenarios,the non⁃functional requirements analysis elements,and the design constraints analysis elements are introduced,which leads to the functional architecture design of the reactor protection system to guide the subsequent detailed design.The study is also applicable and useful for the design of other instrumentation and control systems.
