As the Nuclear Regulatory Commission begins a presidentially ordered review of U.S. nuclear power-plant safety, the NRC's chief operations officer says no major safety changes are needed.

The U.S. has called for evacuating a 50-mile radius around the stricken Japanese nuclear plant. If a similar disaster were to require evacuation around the Indian Point plant, the comparble circle would include almost all of New York City and a big chunk of New Jersey. Despite an evacuation "plan," such an evacuation on short notice would be unrealistic.

"The birth of the 'nuclear renaissance' and proposed construction of up to 100 new nuclear reactors in the United States will be crippled by the crisis in Japan as regulators struggle to incorporate 'lessons learned' into the country's existing nuclear fleet, a former member of the Nuclear Regulatory Commission said [Friday]."

"The U.S. government on Friday said that "miniscule" amounts of radiation were detected in Sacramento, California, but that no radiation levels of concern have been uncovered in United States."

"That it would take more than 20 years for federal regulators to finally propose toxic emissions standards for the power industry is testament to both the slow wheels of bureaucracy and the clout of the nation’s utility and coal interests, which bitterly — and for years, successfully — fought the controls, even as other industries bowed under."

"The U.S. government said on Friday it had struck a deal with wildlife advocates to remove some 1,200 wolves in Idaho and Montana from the endangered species list."

"The chairman of the Nuclear Regulatory Commission said Sunday morning that the spent fuel pools at American nuclear reactors are less vulnerable than the ones in Japan because of steps ordered by his agency after the attacks of Sept. 11, 2001, including having utilities prepare to use fire hoses to pump in extra water in the event ordinary cooling systems are knocked out."

"The Nuclear Regulatory Commission failed to resolve known safety problems, leading to 14 'near-misses' in US nuclear power plants in 2009 and 2010, according to a new report from a nuclear watchdog group."

"A U.S. EPA report suggesting that Americans have significantly higher cancer risks because of toxic emissions from motor vehicles has reopened the debate over dangers posed by outdated diesel engines."
