UNIT SHUTDOWNS AND POWER REDUCTIONS DOCKET NUMBER : 50-382 UNIT NAME : WATERFORD 3 DATE OF REPORT : October 12,1998 COMPLETED BY : D. S. Freeman TELEPHONE: (504) 739-6575 1

1 REPORTING PERIOD : September,1998 Outage Date Duration Shutdown Cause, Comments and Number (yymmdd) Type (Hours) Reason Method Corrective Actions 98-04 980910 S 47.6 A 1 Anomalies were discovered in the oil of Main Transformer B, predicating future failure of the transformer. A controlled shutdown of the unit was performed to disconnect the transformer. The plant then operated at a reduced power level with the remaining Main Transformer while the damaged one was swapped out with a spare. (see CR-98-1179) 98-05 980917 F 314.8 A 1 Elevated levels of leakage were l being experienced from the Pressurizer Code Safety Valves. The unit was conservatively shut down due to leak-rate projections. Both Safety Valves were replaced. (see CR-98-1195)

Return to power was delayed by 4% days due to the threat by Hurricane Georges i i and requirements to receive NRC and FEMA approval for post-hurricane restart.
