o DOCKET NO: 50-413 UNIT: Catawba 1 DATE: 4/15/86 NARRATIVE SIRefARY Month: March. 1986 The unit began March at 100% but was forced to shutdown on March 9, 1986 when cooling water to the Generator was sharply reduced by a clogged strainer. Work was also required on Feedwater System valves and an Auxiliary Building Carbon Filter which is required operable prior to startup. The unit returned to service on March 13.

On March 17 the unit was forced to reduce power because of Mechanical penetrations which were not tested within the specified surveillence period. The unit tested the penetrations and began to increase power at a reduced rate due to Core power distribution limits. The unit was back at 100% on March 19.

On March 21 the unit was forced to reduce power to 25% to repair a Feedwater Isolation valve, but was back at 100% on March 23, where it remained for the balance of the month.
