Application of digital monitoring system in water-cooled isotope system of China Advanced Research Reactor

Digital Monitoring System is one of important part of Water-cooled Isotope System, it is responsible for on-line monitoring on operation condition of Water-cooled Isotope System, and it is a safety operation command centre of Water-cooled Isotope System. Based on the technology principle of Water-cooled Isotope System, this article analyzed the characteristic and structure of Digital Monitoring System. The system is achieved by advanced Schneider computer control system, and accomplishes thermal parameters measure, radiation monitor, electrical control through monitoring, displaying, warning, storage and printing for system data, and gives forecast and warning when system has abnormal working trend. The realization of the system can make operators get various kinds of system data to monitor operation condition of whole system, and ensure operators accomplish operate more expediently and exactly. In the process of fixing and commissioning, abundance operation data is accumulated and many problems are improved, all of these can provide sufficient and authentic information for henceforth safety analysis and estimate of Water-cooled Isotope System and has important reference significance.
