DUQUESNE LIGHT COMPANY Beaver Valley Power Station NARR/SIVE

SUMMARY

dF MONTHLY OPERATING EXPERIENCE - DECEMBER 1982 December 1 Station was in operational mode 1 with reactor power at a through nominal 100% and the reactor coolant system at normal December 8 operating temperature and pressure.

December 9 Commenced redu'cing the load at 0901 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.428305e-4 months <br /> on the 9th to 27%

thro ugh reactor power in order to repair a broken stem on the 1A Main December 10 Feed Regulating Valve [FCV-FW-478). At 0435 hours0.00503 days <br />0.121 hours <br />7.19246e-4 weeks <br />1.655175e-4 months <br /> on the 10th, the valve, [FCV-FW-478), was returned,to service and reactor

, power was increased back to a nominal 100%.

"ecember 11 On the lith, the station was in operational mode 1 with reactor through power at a nominal 100% and the' reactor coolant system at December 12 normal- operating temperature and pressure. A load reduction of 100 MWe was begun upon request by the system operator at 2300 hours0.0266 days <br />0.639 hours <br />0.0038 weeks <br />8.7515e-4 months <br /> on the lith and completed at 2326 hours0.0269 days <br />0.646 hours <br />0.00385 weeks <br />8.85043e-4 months <br />. The system operator requested a further reduction of 150 MWe at 2345 hours0.0271 days <br />0.651 hours <br />0.00388 weeks <br />8.922725e-4 months <br />. This was completed at 0019 hours2.199074e-4 days <br />0.00528 hours <br />3.141534e-5 weeks <br />7.2295e-6 months <br /> on the 12th with reactor power at approximately 70% and the main unit generator output at 620 MWe gross. At 0830 hours0.00961 days <br />0.231 hours <br />0.00137 weeks <br />3.15815e-4 months <br />, a load in-crease was begun. Reactor power was stabilized at 97% at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> in order to perform a heat balance. At 1115 hours0.0129 days <br />0.31 hours <br />0.00184 weeks <br />4.242575e-4 months <br />, the load was increased to 100% reactor power.

December 13 Station was in operational mode 1 with reactor power at a .

through nominal 100% and the reactor coolant system at normal operating December 23 temperature and pressure.

December 24 The following changes taok place during this period at the through request of the system operator: At 0001 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> on the 24th, December 31 a load reduction was begua.

t DUQUESNE LIGHT COMPANY-Beaver Valley Power Station MAJOR SAFETY-RELATED MAINTENANCE - DECEMBER 1982

1. Repaired actuator on auxiliary feed pump supply trip valve [TV-MS-105B).
2. Maintenance work on the 1A Main Feedwater Regulating Valve [FCV-FW-478]

was performed twice during the month of December. On the 2nd, Instru-ment and Control repaired the valve actuator and instrumentation. On the 9th, a broken valve stem was replaced.

3. Electrical maintenance inspected power-operated relief valve [MOV-RC-535]

after the valve failed to stroke fully open during an operations surveil-lance test. No apparent cause could be found for the problem. The valve was subsequently stroked satisfactorily and declared operable.
