Twin nuclear reactors at Taishan in China have been sealed into their concrete domes despite fears that the reactor vessels have serious metallurgical defects. No safety test data has been released by the two companies in charge, EDF and CGN, to show that the reactors will not crack in operation, releasing radioactivity.
President Obama should overcome political constraints in Hiroshima this week to say 'sorry' for the nuclear bombs, writes Linda Pentz Gunter. Even more important, he must change his stance on nuclear weapons - abandoning the US's $1 trillion WMD modernization program and lifting the threat of world-destroying nuclear conflict.
Another week, another series of disasters for EDF and it's Hinkley C nuclear power project, writes Oliver Tickell, with the company's credit rating downgraded partly due to its exposure to the project, and its Chinese partner CGN ruling out a takeover of the site. How much longer can the tragicomedy continue before the curtain falls?
With five reactors closed in the last three years, the US nuclear industry is in shutdown mode, writes Linda Pentz Gunter - and that means big spending on decommissioning. But now the nuclear regulator is set to exempt owners from safety and emergency costs at their closed plants - allowing them to walk away from the costs and liabilities, and palm them onto taxpayers.
Britain's nuclear bomb test veterans suffered severe genetic damage from radiation, writes Chris Busby, and their case for compensation is being heard in the High Court today. Key to their case is evidence of similar damage inflicted on in utero babies exposed to radiation from the Chernobyl disaster, and how the dreadful health impacts of radiation cascade down to future generations.
Tidal lagoons could generate 8% of the UK's electricity, writes Stephen Tindale, and go on doing so for 120 years to come. With the Hinkley C nuclear project looking ever more dicey, and with promises to shut down coal fired generation by 2025, a promised new tidal lagoon In Swansea Bay would come in very useful. So why hasn't the government included it in the Energy Bill?
Planned air transports of high-enriched uranium from Dounreay in Scotland to the US state of Tennessee would risk of accident or a terrorist seizure of weapon-usable nuclear material, writes Ernie Galsworthy. The motive for the transport appears to be purely commercial - and would thus put the public at needless risk for the sake of a cut-price nuclear waste / fuel deal between US and UK authorities.
Almost entirely unknown to the outside world, and even to most local residents, hundreds of square kilometres of South Africa's Karoo dryland have been bought up by uranium mining companies, writes Dr Stefan Cramer. With no strategic assessment of the industry's devastating impacts and massive water demand, official permission could soon be granted for vast open pit mines.
Field studies show that the intense radioactivity released by the Chernobyl and Fukushima nuclear disasters is seriously and unequivocally damaging to wildlife, writes Timothy A. Mousseau - in stark contrast to theoretical studies that show little or no impact on plant and animal health and populations.
The Chernobyl nuclear catastrophe may have scared most of the world off nuclear power, write Jan Haverkamp & Iryna Holovko. But mysteriously, not Ukraine, where the reactor meltdown actually took place. Thirty years on more than half of Ukraine's electricity is still nuclear, while the power sector is dominated by powerful oligarchs. So what are the chances of a post-nuclear Ukraine?
The Chernobyl sarcophagus which has long contained the fissured reactor core is at risk of collapse, writes Claire Corkhill. The solution: build a pair of tracked arches 260m wide and 100m high, and slide them over the site to enclose it for a century to come: so creating a sealed space for robots and remotely operated machinery to deconstruct the reactor and sarcophagus piece by radioactive piece.
Thirty years since the 1986 nuclear disaster at Chernobyl the impacts are still being felt, writes Ian Fairlie, and they will persist long into the future. Some 40,000 cancer deaths can be expected across Europe over the next 50 years, and 5 million people still living in areas highly contaminated with radiation. Yet the nuclear madness continues, with even Belarus building new nuclear reactors.
Thirty years after Chernobyl former Soviet leader Mikhail Gorbachev remains haunted by the world's greatest ever industrial catastrophe, writes Linda Pentz Gunter. Now 85 and a committed environmentalist, he's still campaigning to bring the failed nuclear experiment to an end before further disasters follow, and encouraging a clean, efficient and renewable global energy economy.
Belarus may have taken the brunt of the fallout from the Chernobyl nuclear disaster in Ukraine, writes Kieran Cooke. But now it's pushing ahead with its own nuclear power station at Ostrovets - just 50km from Lithuania's capital, Vilnius, where the project is causing widespread public concern.
Evolutionary biologist Timothy Mousseau and his colleagues have published 90 studies that prove beyond all doubt the deleterious genetic and developmental effects on wildlife of exposure to radiation from both the Chernobyl and Fukushima nuclear disasters, writes Linda Pentz Gunter. But all that peer-reviewed science has done little to dampen the 'official' perception of Chernobyl's silent forests as a thriving nature reserve.
Why do we humans resort to shooting, whenever a challenging problem confronts us? Whether it's culling badgers to protect hedgehogs, or renewing the Trident missile threat with expensive upgrades, our species seems determined to upset the balance of nature and harmony on Earth by shooting first - and never asking the questions at all.
Don't believe the spurious claims of nuclear shills constantly doing down renewables, writes Mark Diesendorf. Clean, safe renewable energy technologies have the potential to supply 100% of the world's electricity needs - but the first hurdle is to refute the deliberately misleading myths designed to promote the politically powerful but ultimately doomed nuclear industry.
The nuclear industry is forever reinventing itself with one brilliant 'new' idea after another, Amory Lovins wrote in this classic 2009 essay. But whether it's touting the wonders of future SMRs, IFRs or LFTRs, the reality never changes: the reactors they are building right now are over time, over budget and beset by serious, entirely unforeseen technical problems.
Just as climate change deniers leap from scientific uncertainty over the precise impacts of greenhouse gas emissions to certainty of little or no impact at all, so 'pro-nuclear environmentalists' conflate uncertainty of the mortality arising from Chernobyl and other nuclear disasters to certainty of few if any deaths, writes Jim Green. Their position is equally indefensible.
Britain is shipping 700kg of highly-enriched uranium capable of making scores of nuclear bombs to the US, writes Gordon MacKerron. The move is a symptom of a huge problem that's afflicting all nuclear nations - what to do with their nuclear wastes? The only real solution is deep geological disposal. But it's politically fraught, technically challenging, very expensive - and has yet to be done.
Nuclear power sites in Belgium have been targetted by Daesh radicals seeking radioactive materials to use in terrorist attacks, write Robert J Downes & Daniel Salisbury. One top nuclear researcher has come under hostile surveillance, while 'insider threats' have led to 11 workers being excluded from nuclear sites. But despite increased security, the threat has not gone away.
EDF in the UK may be propelled by its disastrous nuclear ambitions, writes Chris Goodall. But across the Atlantic it's another story: the company is the US's biggest wind developer, and selling its power, profitably, for under 40% of the price it has been promised for Hinkley C, including federal tax credits.
For Saskatchewan, uranium is an important part of the economy, but for the province's indigenous peoples, the land is everything. It is filled with relationships between beings who dwell together in an interconnected web. Their traditional ecological knowledge is not just a set of terms or data, but a deep, broadly-viewed reality which contains systematic respect for all creation.
The tiny Pacific state of the Marshall Islands has given oral evidence to the International Court of Justice against all nuclear armed states for failing to pursue disarmament. The UK, India and Pakistan were present to deny the charges, but the US, Russia, France, China, Israel and North Korea have denied the ICJ's compulsory jurisdiction.
