Susquehanna Nuclear will test all sirens that are part of Susquehanna Steam Electric Station’s (“SSES” or the “Station”) Emergency Notification System on Thursday August 18th at 11 a.m. During the test, all sirens within a 10-mile radius of SSES will sound in a steady tone for approximately three minutes.

“We test sirens periodically, with this full-scale test conducted annually, to ensure that SSES’ Emergency Notification System (“EAS”) is working properly,” said Jay Barnes, Manager –Emergency Planning. “The sirens are an important part of our EAS, signaling the public to tune in to local EAS radio or television stations for information and instructions. Our proactive testing helps to ensure that the system is ready in the event it is ever needed.”

After the sirens sound, local EAS radio and television stations will carry a message about the test. Emergency notification features on mobile devices also may be activated during this test. No public action is required during this test. In all cases, the sirens sounding is not a signal to evacuate, but rather a way to alert individuals to tune in to an EAS television or radio station for information and instructions.

A list of EAS stations can be found in SSES’ Nuclear Emergency Information Brochure, mailed annually to households and businesses within its Emergency Planning Zone (within a 10-mile radius of the Station), or online at www.susquehannanuclear.com/emergency-planning/.
