This paper presents the results of a review of light water reactor High Pressure Injection System (HPIS) operating experiences reported in the Nuclear Power Experience Data Base, Licensee Event Reports, Nuclear Plant Reliability Data System, and plant records. The purpose of the review is to evaluate the potential significance of aging as a contributor to degradation of the HPIS. Tables are presented that show the percentage of events for HPIS classified by cause, component, and subcomponents for pressurized water reactors. A representative Babcock and Wilcox plant was selected for a detailed study. The US Nuclear Regulatory Commission's Nuclear Plant Aging Research guidelines were followed in performing the detailed study that identifies components susceptible to aging, stressors, degradation mechanisms, and failure modes for the HPIS. 3 refs., 2 figs., 6 tabs.
