SUMMARY
OF OPERATINO EXPERIENCE 10/01/85 At the beginning of the month the Ouane Arnoid Energy Center was operating at 100% of rated power with 542 MWe not going out to the grid.
The plant was in day $ of a 30 day LCO for repairs to the 80' Hain Steam line Isolation valve-Leakage Control System (MSiv-LCS), and da y 2 of a 30 day LCO for repales to the
'B ' Resl dua l Heat Removal Service Water (RHR$W) pump discharge check valve.
10/02/85 At 200$ hours after completion of planned maintenance on the pump discharge check valvo, the
'B' RHR$W pump was returned to service thus en dlnq the 30-day LCO.
10/04/85 At 0733 hours0.00848 days <br />0.204 hours <br />0.00121 weeks <br />2.789065e-4 months <br /> the
'A' Control Ro d Dr i ve (CRO) pump was removed f rom service for repairs of minor leaks to the pump seal cooling piping.
At 1735 hours0.0201 days <br />0.482 hours <br />0.00287 weeks <br />6.601675e-4 months <br /> repairs were complete and the pump was returned to ser vice.
10/05/85 At ISIS hours a 7 day LCO was entered when personnel viewing the four Drywell Sump Timers noted three of the four timers did not start at the appropriate times during manual pumping.
Repales were completed on 10/11/85 at 2227 hours0.0258 days <br />0.619 hours <br />0.00368 weeks <br />8.473735e-4 months <br /> and the system was returned to service, thus cancelling the LCO.
