The Palo Verde Nuclear Generating Station, just west of Phoenix, is conducting its annual siren test on Thursday.

Maricopa County Department of Emergency Management spokesman Ron Coleman says people living within a 10-mile radius of the Palo Verde Nuclear Generating Station will hear sirens at noon and 12:30 p.m.

"There’s 70 sirens strategically placed around that area. Those sirens are going to sound a full test," said Coleman.

Coleman says the county will also send out text alerts, similar to an Amber Alert, to cellphones in the area.

Besides ensuring the sirens work, the test is also about making sure folks know what to listen for in the event of a real emergency.

The Palo Verde Generating Station near Tonopah is the nation’s second-largest nuclear facility.
