Abstract： Background : The molten salt pump is one of the main equipment in the thorium based molten salt reactor circuit system, responsible for driving the circulation of molten salt in the circuit. The safety and economy of reactor operation are influenced by the safety and reliability of molten salt pump operation. State monitoring is one of the effective methods to ensure the safe operation of the system. Purpose : In order to detect abnormalities in equipment and system operation timely and provide a basis for condition based maintenance, a study was conducted on the state monitoring and abnormal signal localization of the molten salt pump system. Methods :A desktop application for the real-time monitoring system of molten salt pumps was developed based on the Windows Presentation Foundation (WPF) and Model-View-ViewModel(MVVM). The system is consisted of modules such as monitoring model management, real-time monitoring and alarm, abnormal signal localization, and log query. Results : The relevant operating parameters of the molten salt pump system can be centrally monitored by the system, and the current operating status of the equipment can be displayed in real-time. Signal parameters that may cause abnormalities can be quickly provided after the abnormality occurred. Conclusions : The necessary operational information can be provided by the system for operators. The system is helpful for operators to make operational decisions. Compared to traditional DCS threshold alarms, the timeliness and effectiveness of monitoring have been improved. The foundation for the subsequent application implementation of intelligent operation support is laid.
