DOCKET NO: 50-413 UNIT: Catawba 1 DATE: 9/13/85 NARRATIVE SUlefARY Month: August 1985 Catawba Unit 1 began the month off line completing an outage to repair Condenser tube leaks. On August 1st the operating Feedpump tripped during restart but the unit returned to service a few hours later. The unit was subjected to a number of Moisture Carryover tests to measure the amount of I

moisture being carried over to the turbine from the Steam Generators.

Based upon the results of the tests the unit reduced power to 95% in order to stay within administrative limits. The unit operated at 95% starting August 12, and remained there for the balance of the month.
