'An act of betrayal': Japan to maximise nuclear power 14 years after Fukushima disaster

The Guardian > Energy

More than a decade after the triple meltdown at the Fukushima Daiichi power plant, Japan is again turning to nuclear power as it struggles to reach its emissions targets and bolster its energy security. In a draft strategic energy plan due to be approved by the cabinet this month, the trade and industry ministry signalled it was ditching attempts to lessen Japan's reliance on nuclear power in the wake of the Fukushima disaster – the world's worst nuclear accident since Chornobyl 25 years earlier. The document dropped a reference to "reducing reliance" on nuclear energy that had appeared in the three previous plans, and instead called for a "maximisation" of nuclear power, which will account for about 20% of total energy output in 2040, based on the assumption that 30 reactors will be in full operation by then. The plan envisages a share of between 40% and 50% for renewable energy – compared with just under a third in 2023 – and a reduction in coal-fired power from the current 70% to 30-40%. The push to restart reactors idled since the plant was struck by a tsunami triggered by a magnitude-9.0


Inside Fukushima: Eerie drone footage reveals first ever look at melted nuclear reactor with 880 tonnes of radioactive fuel still inside - 13 years after disaster

Daily Mail - Science & tech

Eerie new drone footage has for the first time revealed the extent of the damage to the Fukushima nuclear power plant 13 years on from its meltdown. The plant's operators, Tokyo Electric Power Company Holdings, or TEPCO, released 12 photos from inside the site, which are the first ever images from inside the main structural support called the pedestal in the hardest-hit reactor's primary containment vessel, an area directly under the reactor's core. Officials had long hoped to reach the area to examine the core and melted nuclear fuel which dripped there when the plant's cooling systems were damaged by a massive earthquake and tsunami in 2011. The high-definition color images captured by the drones show brown objects with various shapes and sizes dangling from various locations in the pedestal. Parts of the control-rod drive mechanism, which controls the nuclear chain reaction, and other equipment attached to the core were dislodged by the drones. The Fukushima disaster was one of the world's most devastating nuclear mishaps The plant's operators, Tokyo Electric Power Company Holdings, or TEPCO, released 12 photos from inside the site TEPCO officials said they were unable to tell from the images whether the dangling lumps were melted fuel or melted equipment without obtaining other data such as radiation levels.


Fukushima disaster has created boar-pig hybrids, scientists say

Daily Mail - Science & tech

Japan's catastrophic Fukushima disaster in 2011 has resulted in a unique species of boar-pig, a new study reveals. Researchers investigating the effects of the nuclear disaster on animals in the area report that radiation has had no adverse effects on their genetics. However, wild boars (Sus scrofa leucomystax) have proliferated in the area, after being left to roam freely from the lack of humans. The boars have bred with domestic pigs (Sus scrofa domesticus) that escaped from nearby properties after farmers had to flee, creating a new hybrid species. Rare spotted wild boar observed inside the evacuated area of Fukushima, Japan, indicative of the'introgression' - the transfer of genetic information from one species to another - with domestic pigs Images from remotely-operated cameras indicate wildlife is flourishing in Fukushima's exclusion zone. Wildlife ecologist James Beasley of the University of Georgia and colleagues used a network of 106 remote cameras to capture images of the wildlife in the area over a four-month period.


Cheap power the key to AI-based business The Japan Times

Human brains are extremely energy-efficient. When a person thinks in a concentrated manner, his or her brain consumes a mere 21 watts of electricity. But AI doing the same degree of intensive thinking requires over 10,000 times more electricity. If that is the case, the international competitiveness of businesses will depend on factors concerning the supply and cost of electricity in their home country. How, then, does Japan stand with regard to power supply and cost?


U.N. hears how the Fukushima disaster is transforming Japanese students into agents of change

The Japan Times

NEW YORK – For a dozen students from Futaba Future High School in Fukushima Prefecture, a recent visit to the United Nations was a chance to share their plans to improve the lives of others by drawing from their catastrophic earthquake and tsunami experiences as a source of strength. Despite overcoming enormous hurdles in the aftermath of the March 11, 2011, disaster that took more than 19,000 lives, the surviving students have moved forward with aspirations of choosing future paths to benefit the global community. "Thanks to all my experiences like getting bullied, joining the drama club and studying at my high school, I think I could grow well," Satsuki Sekine told U.N. diplomats, staff and youth representatives who gathered to hear their presentation on the current situation in Fukushima early this month as part of a scheduled visit while in New York. The 17-year-old explained how drama can be used to portray the challenges of discrimination and conflict "not as an abstract concept but with specific and visual examples." Recounting how the tsunami rendered her home unlivable, she explained how her life in Tomioka as a normal 9-year-old was turned upside down.


Fukushima disaster: The robots going where no human can

BBC News

Robots have become central to the cleaning-up operation at Japan's Fukushima nuclear power plant, six years after the tsunami that triggered the nuclear meltdown.

Radiation, risk and robots: Ripping out a reactor's heart

The Japan Times

MUELHEIM-KAERLICH, GERMANY – As head of the Muelheim-Kaerlich nuclear reactor, Thomas Volmar spends his days plotting how to tear down his workplace. The best way to do that, he says, is to cut out humans. About 200 nuclear reactors around the world will be shut down over the next quarter century, mostly in Europe, according to the International Energy Agency. That means a lot of work for the half a dozen companies that specialize in the massively complex and dangerous job of dismantling plants. Those firms -- including Areva, Rosatom's Nukem Technologies Engineering Services, and Toshiba's Westinghouse -- are increasingly turning away from humans to do this work and instead deploying robots and other new technologies.


Five years after Fukushima disasters, region encourages rise of robotics

The Japan Times

Japan is spending more than 1 billion to resurrect the area around the wrecked Fukushima No. 1 nuclear plant as the country's "Innovation Coast." The region is trying to capitalize on technology developed in the five years spent cleaning up the worst nuclear disaster since Chernobyl, including Hitachi Ltd. and Toshiba Corp. robots that slither like snakes or cruise through radioactive water like speed boats to investigate the flooded reactors. Fukushima Prefecture -- like Beirut or post-bankruptcy Detroit -- is ripe to develop a strong tech community, according to Samhir Vasdev, an innovation consultant at the World Bank. "To lead the future from Fukushima, we must overcome our failures," Fukushima Gov. Masao Uchibori said at the Foreign Press Center in Tokyo last month. "Creating new industries will attract new people, which will be vital to revitalizing the region."
