DELTA, PA - Exelon Generation will conduct its semi-annual, full volume test of the new emergency warning sirens with battery back-up on Wednesday, Dec. 4 at approximately 1:00 p.m. EST. This is just one of two semi-annual tests scheduled for the first Wednesday of June and December each year.
The semi-annual sounding replaces the full, three-minute sounding on the first Wednesday of each month-a process that began October 2, 2013 when the original sirens were retired. Exelon Generation replaced all 97 emergency warning sirens in the 10-mile radius around Peach Bottom Atomic Power Station with new, state-of-the-art units featuring battery back-up. The siren replacement project began in May, 2012.
The Peach Bottom siren investment is part of Exelon Generation's commitment to replace and upgrade the emergency sirens at all of the sites in the mid-Atlantic, including Limerick Generating Station, Three Mile Island Generating Station and Oyster Creek Generating Station. This project will involve a total investment of more than $11 million and the replacement of 400 sirens.
While Peach Bottom has never used the sirens for emergency notification, they are often used by Pennsylvania and Maryland emergency management authorities to notify residents of severe weather. The sirens are not a signal to evacuate, but a warning to tune to a local Emergency Alert Broadcast Station.
Peach Bottom Atomic Power Station is located on the west bank of the Conowingo Pond (Susquehanna River) in York County, Penn. The station is home to two boiling water reactors capable of generating 2,280 megawatts combined. Both reactors began commercial operation in 1974.
