"The operators of 20 of the nation’s aging nuclear reactors, including some whose licenses expire soon, have not saved nearly enough money for prompt and proper dismantling. If it turns out that they must close, the owners intend to let them sit like industrial relics for 20 to 60 years or even longer while interest accrues in the reactors’ retirement accounts."

"TOKYO -- A vast majority of Japanese favor the gradual phasing out of nuclear plants but accept that some reactors need to be restarted to secure enough power in the short term, a newspaper poll showed on Sunday."

"A nuclear reactor on the California coast will remain shut down indefinitely while a team of federal inspectors determines why several relatively new tubes became so frail that tests found they could rupture and release radioactive water, a federal official said Thursday."

"Ten years into a campaign to make radioactive materials harder for terrorists to steal, Congressional auditors have found one hospital where cesium was kept in a padlocked room but the combination to the lock was written on the door frame and another where radioactive material was in a room with unsecured windows that looked out on a loading dock."

"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."

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."
