Development and demonstration of surveillance and diagnostics of rotating machinery for reducing radiation exposure to nuclear power plant personnel. Annual technical progress report, 1 January 1979-30 September 1980
A comprehensive monitoring program for rotating machinery has been initiated at the Grand Gulf Nuclear Station. This program is designed to reduce radiation exposure to personnel resulting from inspection, maintenance, and repair of rotating equipment in a commercial power plant. A computer-based monitoring system is being implemented that utilizes both process and vibration instrumentation to monitor the operational performance of fourteen major pumps, two drive-turbines, twelve motors, three air compressors, the high and low pressure turbines, and the generator-exciter. The monitoring system rapidly scans gross parameter values and warns the operator if alarm limits are exceeded. Once per day the system recalls hourly, gross parameter values and compares these against more sensitive alert limits and performs spectral analysis on all vibration sensors. This provides an early warning of incipient failures. The hourly gross parameters and selected spectral features are also preserved to provide a historical base for diagnostic functions.
