Cavitation-induced damage in flow control valves and downstream piping has been responsible for major operation and maintenance (O&M) costs for the electric power industry for many years. On May 2, 1989, the U.S. Nuclear Regulatory Commission (NRC) issued Generic Letter 89-08 ``Erosion/Corrosion-Induced Pipe Wall Thinning`` which focused attention on flow-induced damage, including cavitation, to valves and piping in safety related systems. However, the problem of cavitation damage to flow control valves and related equipment can exist in many power plant piping systems. This paper provides several examples of cavitation-related problems which have occurred at several of Commonwealth Edison`s nuclear power generation stations and the actions, some successful and some unsuccessful, taken to resolve them.
