DOCKET NO. 50-528 UNIT NAME PVNGS-1 DATE COMPLETED BY K.A. Chavet Se tember 1991 09/01 0000 Unit began the month in Mode 1, 100% RX power.

09/14 1501 CEA slipped during performance of 41ST-1SF01.

09/14 1510 Commenced power reduction due to COLSS being declared inoperable because of the slipped CEA.

09/14 1722 Entered Mode 3 when RX tripped on High Steam Generator Level after economizer valve SGN-FV1112 failed open. Also received Main Steam Isolation Signal (MSIS) due to High Steam Generator level.

09/14 1730 Declared NUE due to MSIS..

09/15 0401 Terminated NUE.

09/17 0351 Entered Mode 4 to work on pressurizer relief valve. This work was unrelated to the initial cause of the outage.

09/17 2046 Entered Mode 5.

09/21 1742 Entered Mode 4.

09/22 0348 Entered Mode 3.

09/24 0233 Entered Mode 2.

09/24 0709 Entered Mode l.

09/24 1257 Main generator synchronized to the grid.

09/24 1630 Plant stabilized at 18% for RWT boron concentration measurement.

09/25 0000 Commenced power ascension at 3% per hour.

09/25 0730 RX power ascension stopped at 47% for evaluation of RCS iodine levels.

09/25 1100 Commenced RX power ascension.

09/25 1830 RX power stabilized at 65% for boron addition to RWT. Also performed RCS leak rate test, 41ST-1RC02 09/26 1730 Commenced RX power ascension to 100% power.

09/27 0620 Stabilized plant at 98.7% for completion of maintenance on Extraction Drain Pump "B".

09/28 1137 RX power at 100%.

09/30 2400 Unit ended the month in Mode 1, 100% RX power.
