UNIT: Catawba 2 Date: 06/15/95 NARRATIVE

SUMMARY

MONTH: May 1995 Catawba Unit 2 began the month of May in an. outage due to lo-lo '2B' steam generator feedwater level. The unit was placed on-line 05/01/95 at 1457. At 14% power the unit experienced a reactor trip due to loss of feedwater flow at 1603. The unit was placed on-line on 05/03/95 at 1054. During power escalation, the unit held at 20%

power from 1200 to 1550 due to lo feedwater isolation valve temperature. The unit returned to 100% full power on 05/04/95 at 1344 and operated at or near 100% full power the remainder of the month.

NARRATIVE

SUMMARY

l MONTH: May 1995 l

Catawba Unit 1 began the month of May operating at 100% full power..On 05/23/95 at 0841 the unit began decreasing power to investigate a suspected reactor coolant pump seal water return heat exchanger. leak. Ac 1530 the unit held at 45% power until 05/26/95 at 0138 due to reactor coolant pump seal water return heat exchanger maintenance. The unit reduced to 18% power and held from 0440 to 1303 due to '1A' reactor coolant pump upper motor oil level alarm. The unit was taken off-line on 05/26/95 at 1432 due to '1A' reactor coolant pump upper motor bearing site glass vent line replacement (reactor remained critical). The unit returned to service on

~

05/27/95 at 0745. During power escalation, the unit held at 30% power from 1019-to 1150 due to secondary chemistry out of spec. The unit held at 45% power from 1335 to 1351 to evaluate excore nuclear instrumentation system power _ tilt ratio. At 65%

power the unit held from 1500 to 1645 due to adjustment of nuclear instrumentation system / thermal power mismatch. The unit returned to 100% full power on 05/28/95 at 0130 and operated at or near 100% full power the remainder of the month.
