"Eighty percent of the world's nuclear power plants are more than 20 years old, raising safety concerns, a draft U.N. report says a year after Japan's Fukushima disaster. Many operators have begun programs, or expressed their intention, to run reactors beyond their planned design lifetimes, said the International Atomic Energy Agency (IAEA) document which has not yet been made public."

"MANILA, Philippines -- The Asian Development Bank is warning countries to prepare for influxes of people fleeing natural disasters as climate change exacerbates rising sea levels, soil degradation and seasonal flooding."

"It's a sunny morning in the Poconos. As residents prepare to head to work or school, some begin to feel dizzy or light-headed."

Is it safe to extend the life of the aging US fleet of nuclear power plants -- even those whose obsolete designs match those of the failed reactors at Fukushima?

"TOKYO -- A year after a huge earthquake and tsunami caused nearly catastrophic meltdowns at a nuclear plant, Japan is still grappling with a crucial question: was the accident simply the result of an unforeseeable natural disaster or something that could have been prevented?

"Regulators on Friday told the owners of the nation's nuclear reactors to implement new safety rules based on the lessons learned from the earthquake and tsunami that crippled Japan's Fukushima Daiichi nuclear plant a year ago. The Nuclear Regulatory Commission (NRC) said it authorized its staff to issue three immediately effective orders implementing some of the more urgent recommendations."

"As many as 12 of Britain's 19 civil nuclear sites are at risk of flooding and coastal erosion because of climate change, according to an unpublished government analysis obtained by the Guardian."

"FUKUSHIMA, Japan -- Yoshiko Ota keeps her windows shut. She never hangs her laundry outdoors. Fearful of birth defects, she warns her daughters: Never have children."

"Nuclear Regulatory Commission Chairman Gregory Jaczko said Tuesday the agency wasn't on pace to meet its own timeline for improving safety at U.S. nuclear plants in response to the meltdown at Japan's Fukushima Daiichi plant a year ago."

"The NRC will soon issue its first orders in response to the Fukushima accident, but it is also weighing a host of regulatory changes that could impose extra costs on the operators of the 104 reactors in the U.S."
