DOCKET NO: 50 414 UNIT: Catawba 2 L l DATE: $/15/91 NARRATIVE

SUMMARY

MONTH: April 1991 Catawba Unit 2 began the month of April operating at 100% full power. The unit operated at or near 100% full power until 1054 on 04/16, when a power decrease to 10% was begun as a precautionary measure for work on the nuclear service water system associated with the unit i refueling outage. At 1453 on 04/16, the turbine tripped from 256 power due to high level in 'C' steam generator which resulted from the main feedwater control valve not responding. The unit remained off line until 1243 on 04/23. Critien1 path work during this outage included nuclear service water system work and feedwater check valve work. After taking the reactor critical, a delay in putting the generator on line was caused by generator seal oil pressure problems. During the subsequent power increase, the unit was held at 29% power from 0700 to 1000 on 04/24 for a turbine control valve movement test, at 496 power from 1715 on 04/24 l to 0235 on 04/z5 for nuclear instrumentation power misnscesi sdjustments, at 63% power from 0410 to 1405 on 04/25 for '2A' main feedwater pump turbine repairs, at 646 power from 1440 to 1606 on 04/25 for high vibration on '2B' condensate booster pump, and at 68% from 1730 on 04/25 to 0005 on 04/26 for repairs to the '2A' main feedwater pump turbine. The unit reached 100% full power at 1050 on 04/26, and operated at or near 100% full power.for_the remainder of the month, i Prepared by: S. W. Moser Telephone: 704 373 5762 . ~. .}}
