pipe bomb puts arizona nuclear plant on lockdown

from ap: Security officials at the nation's largest nuclear power plant detained a contract worker with a small pipe bomb in the back of his pickup truck Friday, and investigators were searching his apartment, authorities said.

It didn't appear to be an act of terrorism, authorities said, but they were still trying to determine why the device was in the truck.

The worker, identified Friday afternoon as Roger William Hurd of Goodyear, Ariz., was stopped and detained at the entrance of the Palo Verde Nuclear Generating Station, about a half mile from the containment domes where the plant's nuclear material is stored, plant spokesman Jim McDonald said. Security officials then put the nuclear station on lockdown for a few hours, prohibiting anyone from entering or leaving the facility until Friday afternoon.
