Ultrasonic Vibration Monitoring System
The Ultrasonic Vibration Monitoring System (UVMS) was developed to address the industry’s need to monitor the vibration of components through a pressure boundary.
Operating Principle
- Time of flight measurement of an ultrasonic pulse.
Test Data
- Jet Pump Target through 6-inch BWR Cladded Wall.
- The movement of the reflected echo.
Features
- Vibration/Clearance Monitoring
- No Modification to the Pressure Boundary
- Analog Voltage Outputs (4 Channel)
- Digital Outputs: In Range/Warning/Alarms
- Logging Other Plant Signals/Data
Applications
- Hydro Runner Clearance and Seal Gap Monitoring
- Valve Internal Vibration Monitoring
- Pump Impeller Clearance and Vibration Monitoring
- BWR Jet Pump
- PWR Control Rod Drive Mechanism and Core Barrel
- Heat Exchangers
- Startup Testing, Commissioning
Control Rod Drive Mechanism
- CRDM Thermal Sleeve Vibration Monitoring.
