503-556-3713 Ext. 234 OPERATION:

The plant entered January at 100% power. Operation continued until Jan 9, 1982 when a manual reactor trip was ordered due to a failed elbow in an 18-inch steam line to the 5B FW heater. The elbow was replaced and the main generator was synchronized i

onto the gr-id January 11, 1982. The following day the reactor was manually tripped due to a failure of No. 2 inverter and loss of instrument bus Y22.

Two and one-half hours later a high temperature (205'F) appeared for the reactor vessel flange leak-off; a containment entry was made to cycle the reactor vessel flange leak-off manual isolation valves which caused the temperature to return to normal. Later in the day a spurious 4

safety injection (SI) signal was received when instrument bus Y22 was shif ted from YO2 to No. 2 ir erter. The SI was caused by Tave < 553*F briefly and steam line high flow indication. When Y22 was deenergized the steam flow bistables on each loop powered...

(See Attached Page for Continuation)

MAJOR SAFETY RELATED MAINTENANCE:

Completed semiannual preventive maintenance on the east auxiliary FW pump. Completed quarterly preventive maintenance on the diesel fire pump driver. Replaced transformers in Uos. 2 and 4 inverters.

I f

MISCELLANEOUS MAINTENANCE: Completed repairs to the non-ESF electric auxiliary FW- -

pump when it failed to start after the reactor trip on January 9, 1932.

Replaced mechanical seal on north BIT recirc pump.

1 Plugged 16 tubes in 2A FW heater.

l MISCELLANEOUS: IAEA was on site to inspect their camera surveillance equipment.

The primary activity that has been increasing during the current cycle has reached about 75% of technical specification limit.

7 SUMMANY OF OPERATING EXPERIENCE Page 2 from Y22 tripped, completing the SI logic. The main generator was sychronized on the grid early January 14, 1982.

On January 16, 1982 No. 2 inverter failed while at 100% power. An SI with e reactor trip followed due to the steam dump valves opening causing actual high steam flow bistable trips concurrent with low steam line pressure. Loss of bus Y22 failed PT-506 and armed the steam dump and also failed' the summator used to compute TREF which then saw an apparent load rejection and opened the dumps. Laring the reactor startup on January 18, 1982 control rod D2 would not move. The startup was terminated and all rods inserted into the core. A diode in the movable gripper assembly was replaced.

The main generator was sychronized onto the grid at 0550 hours0.00637 days <br />0.153 hours <br />9.093915e-4 weeks <br />2.09275e-4 months <br /> the same day.

On January 26, 1982 power was reduced to 70% power to remove the FW heater string from service. Sixteen tubes were plugged in the 2A FW heater and the train was placed back in service. The plant completed the month'at 100% power.
