 Testing of New Emergency Warning Sirens around Peach Bottom Atomic Power Station to Commence 

 Comprehensive Testing Schedule Announced 


DELTA, PA – Exelon Generation has completed the installation of a new state-of-the-art siren system around the Peach Bottom Atomic Power Station, part of a $13 million investment to upgrade sirens around the company’s nuclear stations. The new system will now undergo extensive testing in accordance with Federal Emergency Management Agency (FEMA) requirements.

The test schedule is as follows:

  • Wednesday, July 17, 24 and 31, 2013 - Three minute test beginning at 1:00 p.m.
  • Tuesday, August 6, 2013 – Six separate tests beginning at 8:00 a.m. (every 90 minutes)
  • In the event of inclement weather, these tests will occur on Thursday, August 8, 2013.

    The siren replacement and tests are part of a larger project to replace 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 and is expected to be completed by the end of 2013.

    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. The sirens are part of Peach Bottom’s extensive emergency response system that includes detailed emergency plans; dedicated off-site facilities; and training and public information materials. A postcard announcing the test schedule has been mailed to all residents who reside within the Peach Bottom emergency planning zone.

    Peach Bottom Atomic Power Station is located on the west bank of the Conowingo Pond (Susquehanna River) in York County, Pa. The station is home to two boiling water reactors capable of generating 2,280 megawatts combined. Both reactors began commercial operation in 1974.
