Overall design of radiation monitoring system formaritime nuclear facilities

The Radiation Monitoring System (RMS) is designed to check continuously the reactor at the operating set points, it assures that no individual and persons receive an unnecessary or hazardous exposure to radiation. According to the process and operation characteristics of Small Modular Reactor (SMR), these radiation monitoring channels can be grouped into the process radiation monitoring subsystem, the effluent radiation monitoring subsystem, the area radiation monitoring subsystem and the Post Accident Monitoring Subsystem (PAMS). Based on the architecture design of RMS, the demand of signal interface and power interface is analysed. Through introducing the marine environment, the problems of anti-shock, vibration, inclination and swing of loads are put forward.
