This paper illustrates a complete inspection, testing, and maintenance program implemented at PECO Energy`s Peach Bottom Atomic Power Station (PBAPS). Concerns that tubes may have been too conservatively plugged due to insufficient data justified a program that included: removal of previously installed plugs; videoprobe inspection of failed areas; extraction of tube samples for further analysis; eddy current testing of selected tubes; evaluation of the condition of insurance plugged tubes for return to service; hydrostatic testing of selected tubes; final repair plan based on the results of the above program. This paper concludes that no single method of inspection or testing should be solely relied upon in establishing: the extent of actual degraded conditions; the source(s) of failure mechanisms; and the details of repair. It is a combination of all gathered data that affords the best chance in arresting problems and optimizing feedwater heater life.
