DUQUESNE LIGHT COMPANY Beaver Valley Power Station Narrative Summarv Of Operating Experience - December, 1979 Date Event December 1 to Station in Operational Mode 3. Main unit generator was off-line December 3 at 0000 hours and the reactor tripped at 0029 hours due to an N-31 source range detector signal spike. Maintained Tavg at 525F for setpoint testing of the main steam safety (pressure relief) valves. The test was completed satisfactorily at 1400 hours on December 2 and RCS cooldown to Operational Mode 5 was commenced. Entered Mode 4 at 1535 hours. Cooldown was temporarily secured at an RCS temperature of 390F in order to maintain steam pressure in the auxiliary steam system. Degassing of the reactor coolant was in progress. Dect2ber 4 Station in Operational Mode 4 with Tavg at approximately 330F. RCS cooldown was still in progress. The residual heat removal system was placed into service at 1630 hours. Began draining the steam generator secondary side at 1910 hours. Decenbar 5 Station in operational Mode 4 with Tavg at approximately 250F and RCS cooldown to Mode 5 in progress. Continued draining the secondary side of the steam generators and began establishing a nitrogen blanket. Entered Mode 5 at 0635 hours and began breaking the containment vacuum. Degassing of the reactor coolant system was resumed at 0730 hours. Secured draining the steam generator secondary side at 1945 hours. Began purging the containment atmosphere at 2140 hours. December 6 Station in Operational Mode 5 with Tavg at approximately 130F. Containment purge and exhaust flow was throttled to 30,000 CFM. Degasification of the reactor coolant was in progress. Opened the containment airlock doors at 1330 hours. December 7 Station in Operational Mode 5 with Tavg at approximately 130F. December 8 Station in Operational Mode 5 with Tavg at approximately 130F. At 0930 hours, drew a steam bubble in the pressurizer and started a reactor coolant pump in preparation for addition of hydrogen peroxide to the reactor coolant. The peroxide was added at 2025 hours to aid the clean-up of the reactor coolant system. December 9 and Station in Operational Mode 5. Reactor coolant system clean-up December 10 in progress. Began the 24-hour load test for the No. 2 Diesel Generator at 1205 hours. e

bdQUESNE LIGHT COMPANY Beaver Valley Power Station Narrative Summary Of Operating Experience - December, 1979 (continued) Date key December 11 Station in Operational Mode 5 with Tavg at approximately 125F. Reactor coolant system clean-up in progress. Completed t.te load test for the No. 2 Diesel Generator at 1248 hours. Comuenced RCS cooldown to 110F for reactor vessel nozzle inspection. December 12 and Station in Operational Mode 5 with Tavg at approximately 110F. December 13 RCS clean-up in progress. Holding RCS temperature steady for reactor vessel nozzle inspection. Started the 1C Reactor Coolant Pump at 1256 hours on December 13, 1979 and energized the pressurizer heaters for boration to the refueling boron concentration. December 14 to Station in Operational Mode 5 with Tavg approximately 120F. December 16 Boration of the reactor coolant to 2050 ppm (refueling mode boron concentration) was in progress. December 17 Station in Operational Mode 5 with Tavg approximately 115F. Began filling the spent fuel pool. December 18 to Station in Operational 5 with Tavg approximately ll5F. Fill December 31 and boration of the spent fuel pool in progress. Major Safety-Related Maintenance - December, 1979_ l. Repairs of the No. 3 and No. 4 Inverters are in progress. 2. Design changes of the low head safety injection pumps are in progress as part of the scheduled major modifications program. 3. Design changes of the grench spray pumps are in progress as part of the scheduled major modifications program. 4 Disassembly and inspection of the inside recirculation spray pumps is in progress. 5. Removal, inspection and overhaul of Bergen-Paterson large bore snubbers is in progress. \\}}\\ }}
