摘要

This report presents an evaluation of service experience with nuclear and fossil feedwater pumps. The scope includes all US commercial light water reactors over 430 MWe in operation in June 1978 and all US fossil fired units over 600 MWe in operation in December 1977. Presented in the report are: the root causes of repetitive failures of feedwater pumps, an evaluation of past practices, engineering judgments and economic trade-offs which have led to feedwater pump unavailability, specific actions which utilities can implement to improve the availability of new and existing feedwater pumps, and recommendations for further research which should lead to improved feedwater pump reliability.
