Survey of feed pump outages. Final report
The emergence of power plant availability as a critical parameter for the electric utilities has motivated this investigation on the reliability and failure mechanisms of feed water pumps. A comprehensive industry-wide survey was made which provides ample data to identify the causes of availability loss resulting from failures of boiler feed, nuclear feed and feed water booster pumps. The specific design, operation and maintenance deficiencies and system related problems responsible for most outages involving feed pump failures are summarized. It is concluded that these pumps need more of the high-technology engineering that is currently being applied to many other types of rotating machinery. Also, it is concluded that less emphasis on maximizing pump efficiency at full load and more emphasis on operating performance over the entire load range is needed. Specific recommendations are made herein which, if implemented, will substantially improve feed pump reliability, both in present and future applications.
