Wireless Emergency Alert system will be tested for the first time
JENKINSVILLE, S.C. — Dominion Energy will conduct annual testing of its V.C. Summer Nuclear Station siren warning system at approximately 1 p.m., Tuesday, April 2. During the test, 109 Early Warning Siren System (EWSS) sirens that are within a 10-mile radius of V.C. Summer will sound for three minutes.
In conjunction with the siren testing, the South Carolina Emergency Management Division, in cooperation with Dominion Energy, the Federal Communications Commission, and local officials will conduct a test of the Wireless Emergency Alert (WEA) and the Emergency Alert System (EAS). The WEA will be tested for the first time during the siren test, as an additional safety enhancement for the public in the surrounding area.
The WEA will geo-target mobile cellular users within an approximate radius of 10-miles around the plant through the Integrated Public Alert and Warning System (IPAWS). During this time, cell phones that are switched on and within range of an active cell tower should be capable of receiving the test message. Cell phones should receive the message once. The test will assess the operational readiness of the infrastructure for distribution of a regional message and determine whether technological improvements are needed. This will be the third WEA test executed for Dominion Energy, and the first for the V.C. Summer Nuclear Station.
The WEA system currently is used to warn the public about dangerous weather, missing children, and other critical situations through alerts on cell phones. It allows customers whose wireless provider participates in WEA and who own a compatible wireless phone to receive geo-targeted alerts of imminent threats to safety in their area through unique tones and vibration.
The EAS test is made available to participants through radio and television broadcasters, cable systems, satellite radio and television providers, and wireline video providers. It is scheduled to last approximately one minute.
Area residents are reminded that the sounding of sirens during this time period is only a test. In the unlikely event of an actual emergency at the plant, the sirens would sound with no prior notice and would alert area residents to tune to an EAS radio or television station for further instructions.
Information about siren tests, nuclear generation and emergency planning is mailed to residents within 10 miles of V.C. Summer Nuclear Station in the annual emergency preparedness calendar.
