SÜS - The Complete Solution
The Complete Vibration Monitoring of Reactor Pressure Vessel Internals, Reactor Coolant System and Reactor Coolant Pumps
 | Vibration Monitoring of Structures and Rotating Machines | | A Complete Solution from the Sensor up to the Analysis and Monitoring System |
The AREVA NP GmbH vibration monitoring system SÜS is a complete solution for vibration monitoring of the reactor pressure vessel internals, reactor coolant system and reactor coolant pumps. SÜS monitors the mechanical vibrations of passive structures in the frequency domain and rotating machines in the frequency domain for early warning and in the time domain for machinery protection purposes. AREVA – as a manufacturer of nuclear power plant components – already has more than 30 years of experience with vibration monitoring systems applied in AREVA and non-AREVA plants. By using SÜS the plant operator can take advantage of the wealth of this experience which has been integrated in the evaluation procedures of the SÜS system. SÜS vibration monitoring systems are currently being used to monitor safetyrelated components in 33 pressure water reactors. | The systematic SÜS concept starts with the selection of sensors which were specially developed for the measurement of vibrations in power plant components – e.g. the SAUM absolute displacement transducer – and optimized for their application in terms of sensitivity and frequency range. They are qualified for use in the harsh conditions prevailing in nuclear power plants and can be remotely calibrated at any time. SÜS automatically performs a calibration of all instrument chains prior to each measurement and documents the current settings. This is the only possible way to implement a really automatic vibration monitoring procedure which excludes incorrect measurements and poorly adjusted instrument chains. The modular design of SÜS guarantees service-friendliness as well as simple extensions to the system and its software. | ||
