"ANGELICA, N.Y. — Questions about the integrity of official water tests are stirring the latest controversy over New York State’s embattled policy of allowing imports of radioactive waste from natural gas drilling operations in Pennsylvania."

"WASHINGTON -- States cannot shut down nuclear plants over safety worries, the United States Court of Appeals for the Second Circuit ruled on Wednesday, upholding a lower court’s decision that allowed the Vermont Yankee plant to keep running despite a seven-year effort by the Vermont Legislature to close it."

"The operator of Japan's crippled Fukushima nuclear plant is preparing to remove 400 tons of highly irradiated spent fuel from a damaged reactor building, a dangerous operation that has never been attempted before on this scale."

"WASHINGTON — A federal appeals court ruled on Tuesday that the Nuclear Regulatory Commission was 'flouting the law' when it stopped work on a review of the proposed nuclear waste dump at Yucca Mountain, despite the Obama administration’s insistence that the site be shut down."

"TOKYO — First, a rat gnawed through exposed wiring, setting off a scramble to end yet another blackout of vital cooling systems at the Fukushima Daiichi nuclear plant. Then, hastily built pits for a flood of contaminated water sprang leaks themselves. Now, a new rush of radioactive water has breached a barrier built to stop it, allowing heavily contaminated water to spill daily into the Pacific."

"Highly radioactive water seeping into the ocean from Japan's crippled Fukushima nuclear plant is creating an 'emergency' that the operator is struggling to contain, an official from the country's nuclear watchdog said on Monday."

"SEOUL, South Korea — Like Japan, resource-poor South Korea has long relied on nuclear power to provide the cheap electricity that helped build its miracle economy. For years, it met one-third of its electricity needs with nuclear power, similar to Japan’s level of dependence before the 2011 disaster at its Fukushima plant. Now, a snowballing scandal in South Korea about bribery and faked safety tests for critical plant equipment has highlighted yet another similarity: experts say both countries’ nuclear programs suffer from a culture of collusion that has undermined their safety."

"Two and a half years after the worst nuclear disaster since Chernobyl, the operator of Japan's wrecked Fukushima plant faces a daunting array of unknowns."
