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 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 Reactor with a design net electrical output rating of 200 megawatts electrical (MWe). The unit is being decommissioned with all nuclear fuel removed from the reactor vessel. Therefore, no Unit 1 operating data is provided in this report.

Dresden Units 2 and 3 are General Electric Boiling Water Reactors; each licensed at 2527 megawatts thermal. The gross outputs of Units 2 and 3 are 832 and 834 megawatts electrical, respectively, with design net electrical output ratings of 794 MWe each. The 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 the Kankakee River for make-up and the Illinois River for blowdown.

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

SUMMARY

OF OPERATING EXPERIENCE FOR FEBRUARY 1999 2.2 UNIT 3 MONTHLY OPERATING EXPERIENCE

SUMMARY

Unit 3 began the period in refueling outage D3R15.

Following completion of scheduled work activities and the vessel hydrostatic test, the reactor start-up began at 0753 on February 24, 1999. The reactor was critical at 1228 that day. At 2118 on February 24, 1999, electromatic relief valves were tested ratisfactorily in accordance with DOS 250-04. The turbine roll began at 1246 on February 25 to support various modification tests.

The unit was synchronized to the grid at 2143 on that day to complete the refueling outage in 26 days. The generator was separated from the grid at 0337 on February 26 for turbine overspeed and other planned tests. The generator was  ;

synchronized to the grid again at 0611 that day.

The unit continued power ascension testing for the I remainder of the period.

4.2 Technical Specification Amendments Amendment 170 and 165 for Dresden Unit 2 and Unit 3 respectively was issued on February 8, 1999.

The amendment relocated the requirement to remove the Reactor Prctection System shorting links under certain conditions to the UFSAR from the technical specifications. Removal of the shorting links enables a non-coincidence high flux scram from any neutron-monitoring instrument Amendments 171 and 166 for Dresden Unit 2 and Unit i 3 respectively was issued on February 16, 1999. l The amendment revised the Technical Specifications ]
