Nuclear Power & Radiation

"The earthquake that shook the East Coast last week rattled casks holding radioactive nuclear waste at a Virginia plant, moving them as much as 4.5 inches from their original position, the plant's operator said.

The 5.8-magnitude quake shifted 25 casks, each 16 feet tall and weighing 115 tons, on a concrete pad at Dominion Resources Inc's North Anna nuclear plant."

Roberta Rampton reports for Reuters September 1, 2011.

"Texas governor Rick Perry tried to sideline a state commissioner who opposed expanding the scope of a nuclear-waste landfill owned by one of the governor's biggest political donors, Reuters has learned."

"The risk that an earthquake would cause a severe accident at a U.S. nuclear plant is greater than previously thought, 24 times as high in one case, according to an AP analysis of preliminary government data. The nation's nuclear regulator believes a quarter of America's reactors may need modifications to make them safer."

"An independent investigation panel has confirmed that [Japan's] Nuclear and Industrial Safety Agency asked utilities in at least three cases to mobilize their employees for government-sponsored symposiums on nuclear power and express supportive or neutral opinions."

"The earthquake that prompted the shutdown of a Virginia nuclear power plant last week may have been more severe than the plant’s reactors were designed to withstand, federal regulators said."

"BIBLIS, Germany — Not since the grim period after World War II has Germany had significant blackouts, but it is now bracing for that possibility after shutting down half its nuclear reactors practically overnight.

"The earthquake that rattled much of the East Coast last week is sparking angry calls from elected officials seeking an immediate reevaluation of seismic risks at two dozen or so commercial nuclear plants around the country, including two in California.

The frustration is directed at members of the federal agency charged with regulating commercial nuclear plants, the Nuclear Regulatory Commission."

"The nuclear regulator said on Thursday that it will require operators of the nation's 104 nuclear reactors to review their earthquake risks as part of an ongoing update of seismic hazards for power plants.

The Nuclear Regulatory Commission said it will provide existing plants with a seismic analysis tool later this year that will allow plants to perform "an updated review."

"Like thousands of other people, Miwa Kamoshita's life was turned upside down when the March 11 tsunami struck the Fukushima No. 1 nuclear plant, leading her and her family to voluntarily evacuate their home in Iwaki, some 40 km south of the crippled power station."
