CORRECTIVE ACTIONS
Corrective actions involved plugging several tubes and applying an overcoat of Duromar after tube plugging to address leakage and repair of a tube-to-tubesheet interface and tubes of the 3AN and 3 BS water boxes.
Long term, the Unit 3 and Unit 4 condenser tube bundles will be replaced under the Extended Power Uprate Project.
ADDITIONAL INFORMATION
EIIS Codes are shown in the format [IEEE system identifier, component function identifier, second component function identifier (if appropriate)].
SIMILAR EVENTS
Turkey Point Unit 4 had a condenser tube leak, LER 2010-008-00, that resulted in a manual plant shutdown.
