Tepco engineers have cleared away the top section of Fukushima Daiichi unit 4's reactor building, ready for work to start on the overbuilding they need for fuel removal.

Honeywell is evaluating a series of upgrades for the Metropolis Works uranium conversion plant following the results of inspections on its preparedness for extreme natural disasters.

The Japanese government has announced it will be able to scale back energy saving targets in some areas thanks to the restart of Kansai Electric's Ohi 3.

Independent regulators should play a greater role in communicating the risks associated with energy generation and distribution because the government is not considered as an impartial source of information, according to a report from the UK parliament's Science and Technology Committee.

Japan has generated its first nuclear electricity in two months after unit 3 of the Ohi plant began supplying power to the grid today. While unit 4 of the plant is expected to resume operation by the end of the month, it is not yet known when the country's other idled reactors will restart.

The faults of every player in last year's Fukushima crisis have been laid out by a parliamentary commission. No organisation was singled-out as responsible - but rather Japanese culture itself. For the continuation of nuclear power in the country, regulation must go through an "essential transformation process."

Tepco workers have dealt with a temporary loss of cooling systems at Fukushima Daiichi unit 4's used fuel pool. Meanwhile, Japan's first reactor to restart after the Fukushima accident has reached criticality.

Japan's nine nuclear power utilities have rejected calls from some of their shareholders to reduce or even eliminate the use of nuclear energy. Tokyo Electric Power Co's shareholders approved a ¥1 trillion ($12.5 billion) injection of state funds which effectively nationalizes the company.

French authorities have laid out the improvements they want to see from the country's nuclear operators to ensure safety in case of extreme natural disasters like those that led to the accident at Fukushima Daiichi.

The appetite of UK business leaders for new nuclear generating capacity has not diminished, despite the Fukushima accident, a poll conducted by the Institute of Directors (IoD) of its members shows. The IoD has published a report calling nuclear energy a "clean, cheap and safe" way of generating electricity.

Permission to restart the first two of Japan's idled fleet of nuclear power reactors has been given by the prime minister following approvals from local municipal and prefectural authorities. Units 3 and 4 of the Ohi plant are both expected to be back at full power by the end of next month.
