1.0 Introduction Dresden Nuclear Power Station is a three reactor generating facility owned and operated by the Comed Company of Chicago, Illinois.

Dresden Station is i

located at the confluence of the Kankakee and Des Plaines Rivers, in Grundy County, near Morris, Illinois.

Dresden Unit 1 is a General Electric Boiling Water l

Reactor with a design net electrical output rating of l

200 megawatts electrical (MWe).

The unit is retired in place with all nuclear fuel removed from the reactor vessel.

Therefore, no Unit 1 operating data is provided in this report.

1 Dresden Units 2 and 3 are General Electric Boiling l

Water Reactors, each licensed at 2527 megawatts l

thermal.

The gross outputs of Units 2 and 3 are 832 and 834 megawatts electrical, respectively, with design l

net electrical output ratings of 794 MWe each.

The i

commercial service date for Unit 2 is 11 August 1970, and 30 October 1971 for Unit 3.

Waste heat is rejected to a man-made cooling lake using l

the Kankakee River for make-up and the Illinois River l

for blowdown.

The Architect-Engineer for Dresden Units 2 and 3 was Sargent and Lundy of Chicago, Illinois.

i This report for November 1996, was compiled by Gary A.

I Abrell of Dresden Regulatory Assurance Staff, telephone number (815) 942-2920, extension 3749.

1 2.0 SUte4ARY OF OPERATING EXPERIENCE FOR November 1996 2.1 UNIT 2 MONTHLY OPERATING EXPERIENCE

SUMMARY

Unit 2 was on system at the beginning of the period near full power.

l At 0126 on November 17, 1996, a load drop began l

for routine surveillance testing.

Following circulating water flow reversal, load increase began'at 1300 from 650 MWE.

At 2100 on November 23, 1996, load drop began to time main steam isolation valves, to scram test l

control rod drives, and to enter the drywell to add oil to 2A Recirc Pump motor.

Commenced load increase at 1430 on November 24, 1996, and reached full power at 0130 on November 26, 1996.

On November 26, the 2% thermal power derating caused by feedwater flow measurement uncertainty was lifted.

At 2000 on November 28, 1996, commenced load drop to change condensate demineralizers and perform i

control rod drive exercising.

Power was l

stabilized at 550MWE at 2245 on November 28 and remained at that level for the remainder of the period.
