Peach Bottom Atomic Power Station will test its emergency sirens next week.

At 1 p.m. Wednesday, all 97 sirens will sound throughout the 10-mile radius around the Delta station.

The sirens were installed last year as part of parent company Exelon Generation's $11 million investment to replace 400 sirens in areas surrounding Peach Bottom, Three Mile Island Nuclear Generating Station and other nuclear power plants it owns in Pennsylvania.

Though they've never been used to notify residents of a nuclear emergency, the Peach Bottom sirens are sometimes used by emergency management authorities in Pennsylvania and Maryland to notify residents of severe weather.

The sirens are tested on the first Wednesday of June and December each year.
