Exelon LaSalle Unit 1 is off-line again

Unit 1 at the Exelon LaSalle Generating Station was taken off line Saturday morning, less than 24 hours after it had returned to 100% generating power. Megan Borchers, Site Communications Manager, said the action was taken to replace seals on 2 pumps that were not performing at optimum levels. The unit had just gone back on line Friday after a refueling and maintenance outage.

Borchers did not say when Unit 1 would be brought back on line.
