"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."

"The operator of Japan's stricken Fukushima nuclear power plant said on Monday that contaminated ground water had likely been flowing into the sea, acknowledging such a leakage for the first time."

"OAK HARBOR, Ohio — Davis-Besse is identified in a new economic report as one of a dozen U.S. nuclear reactors most likely to be closed by their utilities before their licenses expire because of changing energy markets, including falling natural gas prices, rising costs of nuclear operations, repairs, and post-Fukushima retrofits."

"As China pushes an aggressive expansion of nuclear power it is running into a major stumbling block - a breakdown of trust, post-Fukushima, in official assurances of public safety."

"TOKYO — The operator of the Fukushima Daiichi nuclear power plant stood ready Thursday to inject boric acid into one of its most heavily damaged reactors after it found steam emanating from the reactor building. The preventive measure would stave off sustained nuclear reactions in the reactor’s damaged core, though officials stressed that such reactions were a remote possibility."

"ST. PETERSBURG, Russia -- So much for the lessons of Fukushima. Never mind oil spills, the Russian Federation is preparing an energy initiative that, if it has problems, will inject nuclear material into the maritime environment."
