AbstractAbstract
[en] This report documents the results of a study of the Auxiliary Feedwater (AFW) System that has been conducted for the US Nuclear Regulatory Commission's Nuclear Plant Aging Research Program. The study reviews historical failure data available from the Nuclear Plant Reliability Data System, Licensee Event Report Sequence Coding and Search System, and Nuclear Power Experience data bases. The failure histories of AFW System components are considered from the perspectives of how the failures were detected and the significance of the failure. Results of a detailed review of operating and monitoring practices at a plant owned by a cooperating utility are presented. General system configurations and pertinent data are provided for Westinghouse and Babcock and Wilcox units. 33 figs., 53 tabs
