http://www.usatoday.com/news/nation/2007-11-02-az-plant_N.htmA pipe bomb was found in the truck of a contract worker when security staffers stopped him at an entrance to the nation's largest nuclear power plant Friday, a plant spokesman told USA TODAY.
The incident occurred at the Palo Verde Nuclear Generating Station about 50 miles west of downtown Phoenix.
"The sheriff's department has classified it as a pipe bomb," Jim McDonald, a Palo Verde spokesman, told USA TODAY. "How big and how powerful — I don't know."
Maricopa County Sheriff's Office spokesman Doug Matteson said the worker was stopped because of a suspicious package in the vehicle. Sheriff's deputies were called, and the Associated Press reported the worker was taken into custody.
