DUQUESNE LIGHT COMPANY Beaver Valley Power Station NARRATIVE

SUMMARY

OF MONTHLY OPERATING EXPERIENCE - JUNE 1980

, June 1 Station in Operational Mode 5 with the reactor coolant

-system at atmospheric pressure and approximately 100F.

June 2 Station in Operational Mode 5 with the reactor coolant through system pressurized to approximately 100 PSIG for type-C June 8 leak testing of safety injection isolation check valves.

June 9 Station in Operational Mode 5 with the reactor coolant through system at atmospheric pressure and approximately 100F, June 30 MAJOR SAFETY RELATED MAINTENANCE - JUNE 1980 Beaver Valley Power Station Unit No. 1 is presently shut down for major system modifications required by the Nuclear Regulatory Commission. These modifications are performed as construction activities. The following major modifications were performed or in progress during June, 1980.

1. Testing, seal replacement and re-installation of Bergen-Patterson large-bore snubbers was completed. Final inspection of the re-installed snubbers is in progress.

2. Modifications to the refueling water. storage tank are in progress. These modifications provide additional quench spray system capacity and incorporate additional instrumentation required for signaling automatic change-over from injection mode to recirculation mode.

3. Re-installation and construction proof-testing of the modified quench spray pumps are in progress.

4. Inspection and modification, on a continual basis as required, of pipe hangers, supports and baseplates are in progress.

5. Inspection, internal cleaning and modification of the reactor coolant pump motors thrust runners and lift oil system to reduce cavitation and break-

'down of the motor lubrication oil are in progress.

6. Piping modifications to increase the auxiliary feedwater pumps minimum recirculation flow capacity were completed. Preparations for system testing are in progress.

?

7. Inspection and installation of the Unit iow pressure turbine rotors into the Unit L main turbine is in progress.
