State-of-the-Art Siren System for Three Mile Island installed; Tests scheduled

Exelon Generation has completed the installation of a new state-of-the-art siren system around Three Mile Island (TMI) Generating Station, part of a $13 million investment to upgrade sirens around the company's nuclear stations.

The new system includes 96 sirens with improved sound coverage and battery back-up capability. This ensures the sirens will be able to operate and provide notification if electrical service is interrupted. The system will now undergo extensive testing in accordance with Federal Emergency Management Agency requirements for new siren systems. The test schedule is as follows: • Thursday, Oct. 4 at 12:30 p.m. – full three minute test • Thursday, Oct. 18 at 12:30 p.m. -- full three minute test • Thursday, Nov. 1 – six separate tests beginning at 8 a.m. (three minutes each) In the event of inclement weather these tests will occur on Friday, Nov. 2. • Thursday, Nov. 15 at 12:30 P.M. – full three minute test

"Protecting the health and safety of the public is our top priority and emergency planning is a key part of that effort," said Rick Libra, Three Mile Island Generating Station Site Vice President. "The siren system upgrade strengthens the ability to alert the public in the unlikely event of plant or local weather related emergencies."

The sirens are part of TMI's extensive emergency response system that includes detailed emergency plans; dedicated off-site facilities; training and public information materials, all designed to protect public health and safety. A postcard announcing the test schedule has been mailed to all residents who reside within the TMI Emergency Planning Zone. Exelon is conducting the test in cooperation with Cumberland, Dauphin, Lancaster, Lebanon and York Counties and the Pennsylvania Emergency Management Agency (PEMA). The purpose of the sirens is to notify residents to tune to an Emergency Alert System (EAS) radio or television station in case of an emergency.
