Dresden nuclear plant Unit 2 down for maintenance

Spokesman Bob Osgood says Unit 2 was taken down Thursday afternoon so crews can work on small water tubes within the unit's condenser and perform other routine maintenance.

Steam is used to spin the turbine to create electricity, and the condenser converts leftover steam back into water that is reused to make more steam.

Osgood did not say when Unit 2 is expected to be returned to service, but Unit 3 will continue to operate normally and continue producing electricity.

Dresden Generating Station is located about 60 miles southwest of Chicago.
