This week's power outage at Japan's tsunami-crippled nuclear plant may have been caused by a rat Masayuki Ono, spokesman for Tokyo Electric Power Co., the utility that runs the Fukushima Dai-ichi plant, says a 15-centimeter (6-inch) rat was found dead Wednesday near a switchboard. He says the rat may be linked to the power failure, but that more investigation is needed to be sure.

The released videos offer the first minute-by-minute account of the last-ditch effort to avert what would become the worst nuclear calamity since Chernobyl.

Japan's Fukushima nuclear crisis was a preventable disaster resulting from "collusion" among the government, regulators and the plant operator, an expert panel said on Thursday, wrapping up an inquiry into the worst nuclear accident in 25 years.

Kansai Electric Power Co on Sunday restarted the 1,180-megawatt No. 3 unit at its Ohi atomic plant, the utility said, Japan's first nuclear reactor to come back online since the Fukushima crisis, despite public safety concerns.

Japan’s government on Wednesday approved a 1 trillion yen ($12.55 billion) bailout for the operator of the disaster-hit Fukushima nuclear plant, putting the massive utility under temporary state control as it continues to deal with the colossal damages.

The damage to the core of at least one of the meltdown-stricken reactors at Fukushima could be far worse than previously thought.

Documents show that Japanese leaders foresaw the possibility of a meltdown at the Fukushima nuclear power plant, but kept their knowledge secret for months.

Japan's prime minister ordered workers to remain at the tsunami-crippled Fukushima nuclear plant last March as fears mounted of a "devil's chain reaction" that would force tens of millions of people to flee Tokyo, a new investigative report shows.

Iran has yet to give an explanation over a small quantity of missing uranium metal from a research site, the U.N. nuclear watchdog said in a report that voiced concern over possible military links to Tehran's nuclear program.

Iran will present a new advance in its atomic program Wednesday by loading domestically made nuclear fuel into a research reactor in the capital Tehran, a senior Iranian official told a Russian news agency Tuesday.
