The Palo Verde Nuclear Generating Station is about 50 miles west of the center of Phoenix. In changes which went into effect on December 2011, the U.S. government is allowing communities within 50 miles of nuclear power plants to practice less often for major accidents and is recommending that far fewer people who live nearby be evacuated immediately. Under new emergency planning rules, federal regulators also are ending a requirement that emergency personnel always practice for a release of radiation. (AP Photo/East Valley Tribune, Tim Hacker)
