==SUBJECT:==
OUTAGE EXCEEDING 48 HOURS The licensee has informed Region II that the Unit will be shut down for more than 48 hours to inspect and repair main condenser tube problems.
The plant had reduced power to 38 percent on June 1 to repair leaking tubes on the "B" condenser. The reactor subsequently tripped from an unrelated switch problem during a surveillance test. Eddy current testing of the "B" low pressure condenser determined that about 30 tubes would not pass the eddy current probe. Further inspection determined that insulation, installed after startup to improve efficiency on the low pressure heaters and associated piping, internal to the condenser, had come loose and damaged the tubes.
Evaluation and eddy current testing is continuing. The plant is expected to remain shut down for at least another two days to complete repairs.
The Mate of South Carolina has been informed.
This PN is being issued for information purposes only.
This information is current as of 10:00 a.m. (EDT) on June 3.
