1. Introduction Dresden Nuclear Power Station (DNPS) is a two reactor generating facility owned and operated by the Exelon Generation Company, LLC. DNPS is located at the confluence of the Kankakee and Des Plaines Rivers, in Grundy County, near Morris, Illinois.

DNPS Unit 2 is a General Electric Boiling Water Reactor. DNPS Unit 2 is licensed at 2957 megawatts thermal. The gross electrical output is 912 megawatts, with design net electrical output ratings of 864 megawatts. The commercial service date for Unit 2 is August 11, 1970.

DNPS Unit 3 is a General Electric Boiling Water Reactor. DNPS Unit 3 is licensed at 2527 megawatts thermal. The gross electrical output of Unit 3 is 834 megawatts, with design net electrical output ratings of 795 megawatts. The commercial service date for Unit 3 is October 30, 1971.

Waste heat is rejected to a man-made cooling lake using the Kankakee River for make up and the Illinois River for blowdown.

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

SUMMARY

OF OPERATING EXPERIENCE FOR MARCH 2002 A. UNIT 2 MONTHLY OPERATING EXPERIENCE

SUMMARY

From March 01 through March 05, 2002, Unit 2 operated between 725 and 850 MWe, for planned maintenance on Feedwater, Condensate, and Condensate Booster Pumps. Operation at full uprated power requires all of these pumps to be in operation. Therefore periods have been scheduled for power derates in order to perform routine maintenance on these pumps. With the exception of the above description and scheduled surveillances, Unit 2 operated at full power for the remainder of the period.

B. UNIT 3 MONTHLY OPERATING EXPERIENCE

SUMMARY

Unit 3 was shutdown from March 15 through March 24, 2002 to replace Jet Pump hold-down beams. This action was taken in response to a failed jet pump beam at the Quad Cities Nuclear Power Station. With the exception of the above, Unit 3 operated throughout the remaining periods at full power except for short periods for maintenance and surveillances.
