After promising Senators that he would conduct new studies of the health effects of airport X-ray scanners, TSA Administrator John Pistole seemed to say yesterday that the agency did not need to do the study.

"In a direct act of rebellion against Tokyo Electric Power Company, which owns the crippled Fukushima nuclear plant, the local government in Tokyo is moving swiftly to build a huge natural gas facility that would generate as much electricity as a nuclear reactor."

"The European Union on Monday prohibited the use of X-ray body scanners in European airports, parting ways with the U.S. Transportation Security Administration, which has deployed hundreds of the scanners as a way to screen millions of airline passengers for explosives hidden under clothing."

"A team of international researchers said food production would likely be "severely impaired" by the elevated levels of caesium found in soil samples across eastern Fukushima in the wake of meltdowns at the tsunami-hit plant."

"FUKUSHIMA DAIICHI NUCLEAR POWER PLANT, Japan -- The most striking feature at this crippled plant on Saturday was not the blasted-out reactor buildings, or the makeshift tsunami walls, but the chaotic mess."

The U.S. nuclear industry more than a decade ago pinned its hopes for a "renaissance" on getting the friendly Bush Nuclear Regulatory Commission to approve a single reactor design. But engineers say the Fukushima disaster revealed this "safe" reactor could fail in seven different ways. Now public interest groups are asking the NRC to delay licensing it until safety issues are resolved.

"The Union of Concerned Scientists is questioning whether the building housing the Davis-Besse nuclear reactor was properly designed and remains structurally sound. The challenge comes about three weeks after contractors cutting a hole in the building to replace the reactor's lid noticed a long hairline crack on one side of the opening."

"United Nations weapons inspectors have amassed a trove of new evidence that they say makes a 'credible' case that 'Iran has carried out activities relevant to the development of a nuclear device,' and that the project may still be under way."

"Dominion Virginia Power and federal nuclear regulatory staff members covered up knowledge of geologic faulting at the North Anna Power Station site in 1973, according to a U.S. Justice Department memo."

"Tokyo Electric Power Co. detected signs of nuclear fission at its crippled Fukushima atomic power plant, raising the risk of increased radiation emissions. No increase in radiation was found at the site and the situation is under control, officials said."
