A nuclear power plant in central Virginia may have experienced twice as much shaking as it was designed to withstand during last month's rare East Coast earthquake, according to federal nuclear regulators, although no major damage has been found. Dominion Virginia Power, operator of the North Anna plant, confirmed that ground motion from the Aug. 23 quake exceeded the plant's design. But the company contended that the shaking was not as severe as federal regulators claimed. The data, as well as new details of the damage revealed at a Nuclear Regulatory Commission hearing Thursday, paint the clearest picture yet of how the magnitude 5.8 earthquake rocked a nuclear plant only a dozen miles from the epicenter in Mineral, Va. North Anna is the first nuclear power plant in the country to undergo ground motion that exceeded its design.

In March 2004, an attorney for Southern California Edison sat before state utility regulators to propose what seemed like a great deal. The San Onofre nuclear plant was approaching the end of its life span. But Edison wanted to invest $680 million in new steam generators, attorney Carol Schmid-Frazee told a judge presiding over a hearing at the California Public Utilities Commission's San Francisco headquarters. The new equipment, she said, would give the 2,200-megawatt plant a new lease on life, providing cheap, reliable energy in Southern California for decades to come while also saving ratepayers nearly $2 billion.

Nearly seven months after the San Onofre nuclear power plant was closed because of a leak, officials are grappling with whether it makes financial sense to bring the plant fully back online, and if so, who should pay for the necessary repairs. Fixing San Onofre is shaping up to be an expensive proposition, with the price tag jumping into the hundreds of millions of dollars if the plant's massive steam generators require replacing. But keeping San Onofre shuttered is also proving costly to the two utilities that own the plant.

Radiation levels increased sharply inside and outside the Fukushima Daiichi nuclear power plant Thursday, slowing work on the devastated facility again and once more throwing into doubt the integrity of the containment vessels that hold the fuel rods. Tokyo Electric Power Co. officials said the level of radioactive iodine in water at the plant hit levels 10,000 times the permissible limit, preventing workers from getting near the water, which accumulated during early efforts to prevent a full-fledged meltdown by flooding the plant.

Iran said its Bushehr nuclear power plant is safe after confirming some of its industrial computers have been targeted by a computer worm and that it is working to counter the cyber-attack. "The main systems of the Bushehr nuclear power plant have not been damaged," Mahmoud Jahfari, the plants project manager, told the official Islamic Republic News Agency today. "Investigations show that some private software of the power plants employees have been contaminated. " The cyber assault has had no impact on the operations of the plant, Jahfari said.
