"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."

"Significant progress was made last year in strengthening nuclear safety around the world, the U.N. atomic watchdog said in its annual review, despite the 'challenge' posed by a large number of ageing reactors."

"Its stock is sliding. Its economic future is in question. The company that operated and is now responsible for shutting down the Paducah nuclear fuel plant insists it will meet its obligations to safely and cleanly return the aging facility to its owner, the U.S. Department of Energy, next year."

"Tokyo Electric Power Co. has started taking measures to contain highly radioactive groundwater at the Fukushima No. 1 nuclear plant, but its strategy is based on a theory that is disputed by industry experts."

"Japan's nuclear regulator says radioactive water from the crippled Fukushima power plant is probably leaking into the Pacific Ocean, a problem long suspected by experts but denied by the plant's operator."

"Nuclear and radioactive materials are still going missing and the information the United Nations atomic agency receives about such incidents may be the tip of the iceberg, said a senior U.N. official."

"WASHINGTON — As more nuclear reactors across the country are closed, the problem of what to do with their waste is becoming more urgent, government officials and private experts said at a conference here this week."
