本文针对海上浮动堆结构紧凑、空间狭小等特点，设计一种小型化、集成化的辐射监测系统。针对海上浮动堆的辐射监测需求，结合陆上核电厂辐射监测系统的设计经验，对辐射监测系统的功能及组成进行了设计。在此基础上，提出一种分散式就地信号处理与集中式信号处理相结合的系统网络结构。最后，提出了整个辐射监测系统的设备选型建议。提出的小型化集成化辐射监测系统设计方案与国内主流核电CPR1000机组辐射监测系统相比，减少就地信号处理显示设备数量约60%，在不降低系统安全性的前提下，简化了系统配置，降低了运行维护工作量，达到了系统小型化、集成化的要求。
Aiming at the characteristics of compact structure and small space of floating reactor at sea, A small and integrated radiation monitoring system is designed. According to the floating reactor radiation monitoring requirements, Combined with onshore plant design experience, Design features and composition of the radiation monitoring system, This paper proposes a distributed signal processing and the combination of centralized signal processing system network structure, Equipment type selection suggestions are put forward in the end. The radiation monitoring system compared with domestic mainstream CPR1000 nuclear power unit, Reduce local signal processing equipment about 60%, On the premise of not reduce system safety performance, Simplify the system configuration, reduce the workload of operation maintenance, Reach the design request of the system.
