TELEPHONE:
503-556-3713 Ext. 234 OPERATION: The plant entered February operating at 100% power.
Power was reduced to 70% on February 3, when the south main feed pump tripped on low suction pressure.
The loss of the pump was attributed to transients in the heater drain system while an operator was adjusting heater drain tank level.
Power was back at 100% 14 hours1.62037e-4 days <br />0.00389 hours <br />2.314815e-5 weeks <br />5.327e-6 months <br /> later. On February 4 a high differential pressure across a stator cooling water system strainer required the main turbine to be taken of f the line for strainer replacement. The reactor subsequently tripped from 5% power on
'A' steam generator Lo-Lo level caused by difficulty in manually controlling level.
The plant was returned to service the next day and 100% power was reached on February 6.
Full power operation continued throughout the rest of the month with the exception of a 3% power reduction on February 22 for a periodic engineering test to measure the moderator temperature coefficient.
MAJOR SAFETY RELATED MAINTENANCE: Completed hanger support modification on the east and west residual heat removal pumps. Completed semiannual preventive maintenance on the east emergency diesel generator.
MISCELLANEOUS MAINTENANCE: completed repacking the south service water pump.
Replaced bearings and rebuilt the jockey fire pump.
Replaced motor bearings on the south containment chiller.
LICENSE CHANGES:
NONE MISCELLANEOUS:
Reactor coolant system activity continued to increase slightly during February.
The dose equivalent iodine level has reached about 78% of the Technical Specification limit.
