SEPTEMBER 1996 DAY TIME REMARX/H00E 09/01 0000 Unit started the month at 100% power.

09/18 1245 Unit tripped after a reactor coolant system instrument spike that resulted from a lightning strike. Unit entered Mode 3.

09/20 2257 Commenced reactor startup, 2351 Unit in Mode 2.

Reactor entered criticality.

09/21 0517 Unit entered Mode 1.

0608 Unit synchronized to the grid: unit began ramping up power.

09/22 0354 Unit held at 61t power due to high bearing temperature of Heater Drain Pump 2 02. Began overhaul of Heater Drain Pump 2-02.

1407 Reduced power to 56% due to Main Feedwater Pump 2 01 high bearing temperature. Power maintained at 56% to repair the bearing on the Main Feedwater Pump. Also during this time Turbine Plant Cooling Water Pump 2 02 was realigned to resolve high bearing temperature on this pump.

09/26 1650 Repairs completed on all pumps and initiated unit ramp up.

09/27 0553 Unit achieved 100% power.

09/30 2400 Unit ended the month at 100% power.
