Palo Verde Generating Station

TONOPAH, AZ (3TV/CBS 5) -- Officials at the Palo Verde Nuclear Generating Station are working to determine why emergency alarms sounded at the power plant near Tonopah Thursday morning.

The alarms at the plant, which can be heard for about a 10-mile radius, went off around 9:30 a.m. There was no emergency, said APS spokeswoman Jill Hanks. Crews are working to find out what triggered the siren. The alarm system at the nuclear facility is tested regularly, but nothing was scheduled for Thursday morning. APS officials want to reassure residents in the area that there is no real-world emergency.

The Palo Verde Nuclear Generating Station "has been the nation's largest power producer of any kind for more than 25 years," according to APS, which described the plan as "the heart of the APS generation fleet." The facility is located near Tonopah in western Arizona, about 45 miles due west of downtown Phoenix.
