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.

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. l l

At 2100 on November 23, 1996, load drop began to I 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, I 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.
