The Nuclear Regulatory Commission said Friday that it sent the company a list of concerns about its plan to handle a catastrophic flood at Dresden. The plant is in Morris, about 60 miles southwest of Chicago. Exelon has 30 days to respond.
The NRC says recent inspections raised concerns about whether the current plans are adequate in the event of a flood like the one that swamped the Fukushima Dai-ichi (dye-EE’-chee) plant in Japan last year.
Exelon says it’s added better pumps, generators and other equipment to reflect "lessons learned" from Fukushima.
The company plans a public meeting at the station on Dec. 15.
