Peach Bottom Atomic Power Station is getting a facelift, as owner Exelon Nuclear begins replacing all 97 emergency warning sirens in the 10-mile radius of the Delta facility.
The units feature battery backup and are expected to be in place early next year.
"Along with safety and security, we are committed to emergency preparedness," said Tom Dougherty, vice president of the Peach Bottom site. "Although an emergency is unlikely, it is important to replace the existing sirens to ensure sustained reliability of the system."
Though Peach Bottom has never used the existing sirens for emergency notification, they are often used by Pennsylvania and Maryland emergency management authorities to notify residents of severe weather, a company statement said.
As part of an infrastructure investment of more than $9 million, Exelon is also replacing and upgrading emergency sirens at Three Mile Island Generating Station, Limerick Generating Station in Pottstown and Oyster Creek Generating Station in New Jersey.
