SUMMARY
OF OPERATING EXPERIENCE DOCKET NO: '50-344 DATE:
1-5-82 COMPLETED BY:
W. O. Nicholson TELEPHONE:
503-556-3713 Ext. 409 OPERATION The plant operated at or near 100% throughout the month of December.
On December 1, 1981, preferred instrument bus Y 24 failed due to the loss of its associated static inverter Y 28.
Power to Y 24 was switched from the inverter to instrument bus Y O2 with no effect on plant operation.
The inverter has been reenergized on a test load bank to determine the cause of the failure.
The Steam Generator primary-to-secondary leak rate increased over the month from 0.2 gallons per day to about 13 gallons per day. Most of the leakage appears to be from "B" Steam Generator.
The Reactor Coolant System gross gamma activity increased slightly during the month from about 25 pCi/ml to about 29 pCi/ml.
MAJOR SAFETY RELATED MAINTENANCE Completed semi-annual maintenance on the west emergency diesel generator.
t Replaced mechanical seal on the north boron injection tank recire pump.
Completed modification adding additional valves to the Containment post-accident Hydrogen Analysis System.
MISCELLANEOUS MAINTENANCE Worked throughout the month attempting to repair failed static inverter Y 28.
Replaced mechanical seal on the south boric acid transfer pump.
Completed semilannual maintenance on the Joy Air compressors.
Completed annual maintenance on the startup boiler.
LICENSE CHANGES (Effective November 24, 1981)
Amendment 68 - reduces the trip setpoint for high containment pressure as specified in NUREG-0737 " Clarification of TMI Action Plan Requirements".
Amendment 69 - revises requirements for the Fire Protection System.
