Title	Inadvertent Emergency Siren Actuation
Event Description	This event is being reported in accordance with 10CFR50.72(b)(2)(xi). On July 2, 2015, at approximately 0830 EDT, an inadvertent actuation of the Perry Nuclear Power Plant's (PNPP) alert notification system occurred. Seventy-six of seventy-six sirens sounded for three minutes affecting the emergency planning zone in Ashtabula, Geauga, and Lake Counties. Following the actuation, county agencies received calls from members of the public. PNPP's capability to notify the public in an emergency was not affected. The siren actuation was not related to any condition or event at the PNPP. An investigation is in progress to determine the cause of the inadvertent actuation. Preliminarily, it appears that the wrong test was initiated from a county agency; an audible test was initiated instead of a silent test. At the time of the event, the plant was in Mode 1 at 100 percent rated thermal power. The public was informed of the inadvertent actuation by way of the Emergency Alert System (EAS). Additionally, social media was used to respond to social media inquiries. The NRC Resident Inspector has been notified. The licensee notified the Ohio Emergency Management Branch Chief, and the County Emergency Managers of Ashtabula, Geauga, and Lake Counties.
