The unit was back on line at 0641 the following morning.

The unit was limited to 96% power upon its return to service until 1215 on the lith to permit adjustments on the level controllers in the Heater Drain System. These adjustments were necessary to stop flow oscillation

. in the Feedwater System.

The unit tripped at 1426 en March 24 due to high moisture separator and reheater level. Failure of a dump valve caused the trip. This valve was

! repaired and the unit returned to service at 2400 March 25.

Oconee Unit 1 finished the month operating at full power.

Month: March, 1983 Oconee Unit 2 operated at full power until March 10 at 1616 when the unit tripped due to an operator error. While performing a control rod drive surveillance test with two of four breakers open a third was inadvertantly tripped causing the unit to trip. The unit was back on line at 0131 the next day.

March 14 at 1247 the unit tripped due to a loss of 125 volt D.C. power to the turbine control circuitry. The 125 volt sensing relay was changed out and the unit returned to service at 1816 the same day.

Power escalation was held up at 60% power due to problems with the 2B feedwater pump suction relief valve. Repairs were completed the 15th at 2105 allowing the unit to begin increasing load.

Power escalation was held up at 95% power for ten and one half hours due to level problems with the 2E2 heater drain pump. _

, March 19 at 1558 power was reduced to 50% due to a break on the discharge i piping from the 2nd stage moisture separator reheater drain tank. The piping was isolated for repairs and the unit began increasing power at 1900.

The unit finished the month at full power.
