Exelon Nuclear to Replace Sirens Around Three Mile Island Generating Station New sirens to include battery back-up power
LONDONDERRY TOWNSHIP, PA (Nov.19, 2009) Exelon Nuclear will begin a project next week to replace all 96 emergency sirens in the 10 miles around Three Mile Island Generating Station with sirens that include battery back up. The first phase of the project will have contractors visit and identify certain features of each existing siren. The initial phase of this project will take approximately 60 days. Installation of the new sirens will begin in 2011. The new and old sirens will run concurrently for a 4-month period to ensure they operate properly. Completion of the project and removal of the existing sirens is scheduled for 2012. “The sirens are an important part of our emergency plan, and they also benefit the five counties that are able to use the sirens for any emergency,” said Bill Noll, TMI Site Vice President. “The battery back-up will add an additional layer of confidence in our emergency preparedness system. While we are confident in our current siren system, the model we currently use is nearing the end of its service life and it is time to replace all of the sirens with the best available technology.” Contractors performing the first phase of the project will be from ANS Services and individuals performing work will be required to have a company photo ID. Please remember that any contractor wishing to enter a property should produce the proper company ID upon request. This $2.2 million investment around Three Mile Island is part of Exelon Nuclear’s commitment to replace and upgrade the emergency sirens at all of the sites in the mid-Atlantic including Limerick Generating Station, Peach Bottom Atomic Power Station, and Oyster Creek Generating Station. This project will involve a total investment of more than $9 million and the replacement of 400 sirens. The warning sirens are one of several methods used by county emergency management authorities to provide notification of emergencies. Individual counties may activate the sirens to warn the surrounding community of events such as fires, floods, tornados, hazardous material releases, or nuclear energy plant events. The sirens are not a signal to evacuate, but to tune to the local Emergency Alert Station.
