Engineers publish new research on meltdown materials

Engineers at the UK's University of Sheffield have developed materials that they say could be used to help decommission the Chernobyl and Fukushima nuclear power plants. In the new research published today, they report their development of small batches of low radioactivity materials that can be used to simulate lava-like fuel containing materials. LFCMs are a mixture of highly radioactive molten nuclear fuel and building materials that fuse together during a nuclear meltdown.

Lifting of Fukushima evacuation orders re-opens rail link

Lifting of Fukushima evacuation orders re-opens rail link

Evacuation orders in the towns of Futaba, Okuma and Tomioka - imposed after the March 2011 accident at the nearby Fukushima Daiichi nuclear power plant - are to be partially lifted in early-March. The areas include three train stations, allowing a full service to resume on the JR Joban Line.

Revisions to Fukushima Daiichi decommissioning roadmap

Revisions to Fukushima Daiichi decommissioning roadmap

The trial removal of fuel debris from the damaged reactors at Japan's Fukushima Daiichi nuclear power plant will begin at unit 2 in 2021, according to the latest revision to the mid and long-term roadmap towards decommissioning the plant. Meanwhile, the removal of fuel from the storage pools at units 1 and 2 has been delayed by up to five years.

Effectiveness of Fukushima decontamination studied

Effectiveness of Fukushima decontamination studied

Following the March 2011 accident at the Fukushima Daiichi nuclear power plant, the Japanese government launched decontamination work in the surrounding area. With most of this work now completed, the European Geosciences Union has today published an assessment of the effectiveness of the strategies used, with a focus on radiocaesium.

Japan nuclear shutdown did 'more harm than good', study finds

Japan nuclear shutdown did 'more harm than good', study finds

Increased electricity prices and greater use of fossil fuels have led to more deaths following the Fukushima accident in March 2011 than the subsequent evacuation from the area surrounding the nuclear power plant, a new study shows. No deaths have been recorded as a direct result of the accident itself, but the decision to suspend nuclear power generation in response to it has contributed to loss of life, it says.

Evacuation order lifted in Fukushima host town

Evacuation order lifted in Fukushima host town

Some residents of Okuma, the closest town to the Fukushima Daiichi plant, have today been allowed to return home. The evacuation order issued in 2011 has been lifted for the more mountainous and less inhabited western area, where around 380 of the town's former population of 10,500 lived.
