SUMMARY

OF UNIT 1 OPERATING EXPERIENCE March 1987 3/1 The Unit began this reporting. period at full reactor power (860 MWe).

3/10 At 1120, the Unit was removed from the grid-to repair leaking Pressurizer Relief Valves.

3/15 At 1845, Unit 1 became critical, and~at 2102 the Unit was paralleled.

Startup was delayed to repair Pressurizer Vent Valves.

At 2215, the Unit was held at 30% power because of water chemistry.

3/16 At 0400, the. chemistry hold was released and the Unit began increasing power.

Between 0800 and 1035, the Unit was held at 350 MWe because of a failure of the Plant Computer.

At 2000, the Unit was at. full reactor power (860 MWe).

3/28 At 2109, the Unit was limited to 760 MWe due to the loss of the Plant Computer.

3/29 At 1400, the Plant Computer was repaired and the Unit was returned to full power by 1615.

3/31 The Unit ended this reporting period at full reactor power (860 MWe).

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE-March 1987 3/1 The Unit was shutdown at the. start of this reporting period because of a failure of the control system of 21 Feed Regulator Valve.

The failed-component was i

replaced and the Unit became> critical at 2038.

3/2 At 0118, the-Unit was paralleled and.at 0200, the Unit was held at 30% reactor power for a water

. chemistry hold.

At 0330, the chemistry hold was released and the. Unit began increasing power.

At 0900,.the Unit was at a maximum possible power (805 MWe).

After this, power levels were limited by j

1) PSTP-10 coastdown, 2) waste processing 1

restrictions, and 3) xenon transients.

Step power changes are shown below.
