SALEM TOWNSHIP -- If you hear a siren Thursday in the Berwick area, don't be alarmed.
Talen Energy says it is testing all of its sirens within a 10-mile radius of the nuclear power plant outside Berwick.
Testing the sirens is an annual requirement that helps the energy company make sure the warning system is working the right way.
The sirens will sound once at 11 a.m. Thursday lasting about three minutes.
