4 The following is a summary of Plant Operations for September 1990.

e On September 1,1990 at 00:00 hours, the plant was in Mode 1 at 30% power for Chemistry hold. At

07

02 hours, power ascension resumed.- By 22:55 hours, the plant was at 80% power and conducting

flux mapping.

On September 3,1990 at 04:57 hours, the plant was manually tripped due to a low suction pressure on the Main Feed Pumps. At 18:10 hours, a primary plant startup was commenced. By 19:11 hours, the plant was in Mode 2, Startup.

On September 8,1000 at 22:55 hours, the plant was phased to the grid. Power was held at 9% because i

of a Chemistry hold.

On September 9,1990 at 04:29 hours, a load increase was commenced. By 06:35 hours, the plant was -

at 30% power on another Chemistry hold. At 22:43 hours, a load increase was commenced.

j

~ On September 10,1990 at 04:05 hours, the plant was at 80% and conducting flux mapping. At 12:30 hours, the plant reduced load due to Pressurizer level channels 1 and 2 being declared moperable. By t

14:36 hours, the load decrease was stop been declared operable. At 14:59 hours, ped at 70% power because the Pr:ssurizer level a load increase was commenced. By 16:37 hours, the plant was at 80%_ power conducting flux mapping.

On September 14,1990 at 00:24, the plant commenced increasing load. At 02:03 hours, the load o

increase was halted at 83% power due to condensate pump motor current oscillations. At 19:36 hours, a load increase was commenced. At 22:00 hours, the plant was at 90% and holding for completion of steam line break Estrument calibration. By 23:02 hours, a load increase was resumed. At 23:30 hours, the plant was at 92% and power was reduced due to low discharge pressure on the "IB" condensate i

pump. Plant load was then stabilized at 88% power.

H

' On September 15,1990 at 12:30 hours, the plant commenced a load increase. At 12:50 hours, the load was stabilized at 89% power.

['

. On September 16,1990 at 23:03 hours, plant load was reduced due to current oscillations on the condensate pumps.' Load was stabilized at 87 % power.

On Se}itember 19,1990 at 13:10 hours, a load increase was commenced. By 14:00 hours, the plant-was at 92% power and began a load reduction to 88% power due to condensate pump oscillations.

~

On Septetaber 20,1990 at 00:01 hours, the plant commenced a load reduction to troublesh'oot and.

repair the condensate pumps. At 06:28 hours, the load was at 50% power. At 07:15 hours, the Reactor

= was manua.ly tripped due to low feed pump suction caused by the isolation of the "lB" condensate 1

pump. The plant was returned to Mode 3, (Hot Standby).

. On Septemt er 21,1990 at 14:40 hours, the plant entered Mode 4 (Hot Shutdown) to permit working on pressurizer level instrumentation.

On September 24,1990 at 11:40 hours, a plant heatup was commenced. By 12:26 hours, the plant was in Mode 3 (Hot Standby.)

On September 25,1990 at 03:31 hours, the plant reached Mode 2 (Startup).

On September 26,1990 at 03:22 hours, the plant was phased to the grid and in Mode 1,'(Power Operation) at 5%. At 13:28 hours, a load increase was commenced. By 19:45 hours, the plant was at -

30% power and holding for Chemistry. At 21:33 hours, a load increase was commenced.

On September 27,1990 at 20:12 hours, the plant reached at 10Po power.

The plant continued to operate at 100% power for the remainder of the month.
