Technical specification for fabrication of vibration monitoring system for HANARO rotating machinery

This technical specification details the requirements and the acceptance criteria for H/W and S/W design, fabrication, function test, inspection, packing, shipping, installation and quality assurance for the vibration monitoring system for HANARO rotating machinery which will be installed at the Reactor Concrete Island(RCI). The vibration monitoring system for HANARO rotating machinery is classified as Non-Nuclear Safety(NNS), and quality class S. The designed real-time vibration monitoring system can monitor the rotating speed and the vibration level of the rotating machinery of the primary cooling system and the reflector cooling system. When the rotating speed or the vibration level exceeds the allowable limit of the rotating machinery, the vibration monitoring system gives an alarm signal to reactor control room for early warning of the abnormal operation of the rotating machinery. It is capable of showing the rotating speed and the vibration level of the rotating machinery in bar graph and digital form. In addition, the measured data can be displayed to the computer in the reactor control room or in the office via LAN interface. The vibration monitoring system for HANARO rotating machinery will be used as an advance alarming system for the prevention of the abnormal operation of the rotating machinery. It is expected that the developed vibration monitoring system can be utilized for the realization of the preventive maintenance of the rotating machinery
