l Drmden Nuclear Power Station is a three reactor generating facility owned and operated by the Commonwealth l
Edison Company of Chicago, Illinois. Dmden Station is heated at the connuence of the Kankakee and Des Plaina Rivers, in Grundy County, near Morris, Ilhmus.
Dresden Unit 1 is a General Electric Boiling Water Reactor with a design net elecincal output rating of 200 megawatts electrical (MWe). The unit is retired in place with all nuclear fuel runoved from the reactor vessel.
Therefort, no Unit 1 operating data is provided in this report.
Dmden Units 2 and 3 are General Electric Boiling Water Reactors with design net electrical output ratings of 794 MWe each.
l
.l l
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.
