Two public alert notification sirens around Harris Nuclear Plant will be tested on Tuesday, Nov. 15 starting at 8 a.m. This will be a short duration, full-volume test lasting approximately five seconds for each siren. During the annual siren test last week, it was determined that some maintenance was needed on sirens C11 and W17 (see location below). After maintenance is performed, the sirens will be tested to ensure they are working properly. More than one test may be conducted if needed to ensure operability. No action is needed by the public.
As information: There are 83 sirens within 10 miles of the Harris Nuclear Plant. These tests are conducted in cooperation with the State of North Carolina as well as Chatham, Harnett, Lee and Wake counties.
Because this is a test, local broadcasting stations will not interrupt regular programming to broadcast Emergency Alert System (EAS) messages. If there were ever a real emergency at the plant requiring the sirens to be sounded, local radio and television stations would broadcast information and instructions to the public. In the event of severe weather, the siren test will be postponed until a later date.
Duke Energy Progress performs full-volume tests annually. Silent tests are conducted every two weeks and short duration full-volume tests every three months.
